Strength enhancement and retention in magnesium subjected to uniaxial compression using centralized partial drill holes

The automotive industry approached light weighting vehicles using alloys and composites of aluminium and magnesium to improve fuel efficiency. They further introduced sensors to gain insight into real-time monitoring of their components. In the biomedical industry, reducing stiffness of implants, promoting cell proliferation, providing controlled drug delivery, and enabling real-time monitoring of implants has been the focus. With magnesium being a biocompatible material, research on improving the material properties of biocompatible magnesium alloys and composites is ongoing. However, tracking the efficiency of these implants in-vivo is essential and can be done using appropriate sensors. But the question of where to place them and would it affect the structural integrity of the implant needs to be answered. While previous research has explored the effect of through holes in different directions and materials, the effect of a controlled drill hole has not yet been explored. Hence, this study varies the drill depths in pure magnesium from 1 mm to 2.5 mm and drill diameter from 1 mm to 2.5 mm respectively in an 8 mm diameter cylinder to study the same. Further, an exploratory work on the effect of shape of the drill hole has also been taken up. Results convey that the sample with 1 mm drill diameter and 1.5 mm drill depth provided optimum results.

DOUBLE-BARREL DRILL SLEEVE: A SURGICAL INNOVATION FOR PERCUTANEOUS OSTEOTOMY

IntroductionOsteotomy is a key step in distraction osteogenesis. Various techniques of osteotomy have been described with its own benefits and pitfalls. Percutaneous osteotomy using multiple drill holes is one of the most widely used osteotomy techniques. It still remains a challenge however to keep the drill holes aligned prior to the osteotomy. Moreover, the efficacy of percutaneous irrigation practice to keep the temperature low during drilling with this technique is also debatable. With an aim to overcome these challenges, we are introducing a device called the Double Barrel Drill Sleeve (DBDS) to perform percutaneous osteotomies. We attempted to compare this method to the conventional multiple drill holes technique using laboratory experiments and clinical data.Materials & MethodsDBDS has two adjacent parallel barrels that can fit 3.2 to 3.5 mm diameter drill bits. It has a guide member at the drilling end that can be inserted through a pre drilled hole at the near and far cortices of a bone. This provides a constant rotating point for drilling of holes through the barrels. An osteotomy simulation was performed to compare percutaneous drilling with DBDS vis-a-vis a conventional single drill sleeve (SDS) by qualified orthopaedic surgeons, mainly to assess the drilling patterns of both techniques. Percutaneous drilling was done on PVC pipes wrapped in thick sponge to simulate tubular bone with surrounding soft tissue. We also assessed the effect of indirect irrigation on temperature during drilling using the DBDS against a control group on a cadaveric bone model. Ultimately we reviewed our patients who had undergone osteotomy for distraction osteogenesis with DBDS and the conventional technique, and compared their outcomes.ResultsCompletion time for the osteotomy simulation in the DBDS group was significantly faster than the conventional drilling group; 74 seconds to 179 seconds. There was significantly less drilling deviation from the midpoint in the DBDS group as compared to the SDS group. Mean bone temperature during drilling with indirect irrigation using DBDS was significantly lower (32.6'C) compared to the control group (48.4'C). There was no significant difference in healing index between patients treated with DBDS and the conventional method. None of these patients developed non union.ConclusionsPercutaneous drilling with DBDS was quicker and more linear compared to the conventional method. Its double-barreled feature allows effective indirect irrigation during drilling. A comparable healing index in both of the techniques shows its clinical efficacy. These attributes make DBDS a usefull tool to overcome some of the pitfalls associated with the conventional multiple drill holes technique.

Analysis of MRR, Thrust Force, and Torque in Drilling Al/BN/Al2O3 Composites using Hybrid Grey–Taguchi Technique

The demand for hybrid composite materials has been expanding globally in all kinds of mechanical industries. Drilling is one of the basic operations required in manufacturing of various components and choosing optimum parameters of drilling is vital for getting good quality holes. The main objective of our work is to determine the ideal parameters of drilling and tool coatings required to minimize the thrust force and torque in drilling and to maximize the material removal rate (MRR) using Grey–Taguchi technique. Hybrid composite specimen made by reinforcing Al7075 alloy with 4% of aluminum oxide and 2% of boron nitride in stir casting process and drilling was carried out in a sequence at different drilling feed rates (40, 80, and 120 mm/min) and spindle speeds (1,200, 2,400, and 3,600 rpm) in a vertical machining center attached with drill tool dynamometer, using twist drills of diameter 5 mm and point angle 118° made of uncoated carbide, diamond-like carbon (DLC)-coated carbide and high carbon (HC)-coated carbide. The recorded thrust force and torque from the dynamometer and the computed MRRs during each drilling operation are tabulated as per Taguchi’s L27 orthogonal array and the results are analyzed using hybrid Grey–Taguchi technique. In our analysis, the optimum thrust force of 62.12 N and torque of 0.766 Nm were obtained when using a DLC-coated tool at a maximum speed of 3,600 rpm and minimum feed rate of 40 mm/min. An optimum MRR of 178.79 mm3/s was obtained while using DLC coated at a maximum speed of 3,600 rpm and a maximum feed rate of 120 mm/min.

Modeling of process parameters on DSS 2205 through RSM, ANN, fuzzy under cryo-MQL process

Duplex stainless steel (DSS) 2205 is considered difficult to cut machine materials. Therefore, an advanced cooling technique, such as a hybrid Liquid carbon dioxide (LCO2)-Minimum quantity of lubrication (MQL) approach, is proposed for drilling duplex stainless steel 2205. In this research study, parametric optimization was performed by using the Response surface method (RSM) with the box-Behnken design of the matrix. For parametric optimization, select three input parameters: drill diameter, spindle speed, and feed rate, while hole deviation and cylindricity error are output responses. The Analysis of variances (ANOVA) test showed that spindle speed is the major factor that influences both responses, e.g., hole deviation and cylindricity error, with contributions of 38.90% and 59.42%, respectively. The modeling and predictive abilities of developed Fuzzy logic system (FLS) and Artificial neural network (ANN) to the comparison of experimental results. It was also found that the predicted values from regression analysis, artificial neural networks, fuzzy logic interfaces, and the proposed method were in good agreement with actual experiment results. Also, the Artificial neural network model provides a minimum % of error of 1.36% and 2.44 %, respectively responses compared to other models.

Machinability analysis of Typha angustifolia natural fiber reinforced composites through experimental modeling – Influence of fiber orientation

AbstractNatural fiber composites are currently considered to be the most sustainable and renewable substitute for synthetic fiber composites in several low and medium‐density applications. Various research works are ongoing to evaluate the machinability of plant‐based natural fiber composites. In the current investigation, an attempt has been made to fabricate and examine the drilling behavior of Typha angustifolia fiber reinforced (TAFR) composite. Composites were manufactured using Typha angustifolia fibers in unidirectional (UD) and bidirectional (BD) orientations using the epoxy matrix through the compression molding technique. Fibers were characterized using the X‐ray diffraction method to determine the crystallinity index and crystallite size. Drilling experiments were conducted on TAFR composites and using Taguchi's L18 mixed‐level design with various process parameters the experiments were conducted. The optimal experimental combination rendering the lowest value of exit delamination and thrust force was determined using Taguchi‐TOPSIS hybrid approach. A quadratic model was also developed to predict the response of drilling. Drilled hole morphology was analyzed using scanning electron microscopy to know about various failure mechanisms and damages induced during the drilling operations. It was found from the results that the lowest speed and feed rate and higher drill diameter rendered minimal delamination and thrust force for both UD and BD TAFR composites.

Analysis of the influence of surgical robot drilling parameters on the temperature of skull drilling based on Box-Behnken design.

It is easy to cause thermal damage to the bone tissue when the surgical robot performs skull drilling to remove bone flaps, due to the large diameter of the drill bit, the large heat-generating area, and the long drilling time. Therefore, in order to reduce the thermal damage during the robot-assisted skull drilling process, the relationship between the drilling parameters and the drilling temperature during the skull drilling was studied in this paper. Firstly, a dynamic numerical simulation model of the skull drilling process was established by ABAQUS, and a temperature simulation plan for skull drilling was designed based on the Box-Behnken method. Then according to the simulation results, a quadratic regression model of drill diameter, feed rate, drill speed, and drilling temperature was established by using the multiple regression method. By analyzing the regression model, the influence of drilling parameters on the drilling temperature was clarified. Finally, the bone drilling experiment was carried out, and the error percentage was lower than 10.5% through the experiment to verify the reliability of the conclusion, and a safety strategy was proposed to ensure the safety of the surgical drilling process based on this experiment.

Comparison of a Novel Static Computer-aided Surgical and Freehand Techniques for Osteotomy and Root-end Resection

IntroductionThis study compared the accuracy and efficiency of a novel static computer-aided surgical technique using a 3-dimensional (3D)-printed surgical guide (3D-SG) with a fully guided drill protocol (3D-SG FG) to the freehand (FH) osteotomy and root-end resection (RER). MethodsForty-six roots from 2 cadaver heads were divided into 2 groups: 3D-SG FG (n = 23) and FH (n = 23). Cone-beam computed tomographic scans were taken preoperatively and postoperatively. The endodontic microsurgery was planned in Blue Sky Bio software, and the 3D-SG was designed and 3D printed. The osteotomy and RER were conducted using a guided twist drill diameter of 2 mm and an ascending tapered drill with diameters of 2.8/3.2, 3.2/3.6, 3.8/4.2, and 4.2 mm with respective guided drill guides. Two-dimensional and three-dimensional virtual deviations and angular deflection were calculated. Linear osteotomy measures and root resection angle were obtained. The osteotomy and RER time and the number of mishaps were recorded. ResultsTwo-dimensional and three-dimensional accuracy deviations and angular deflection were lower in the 3D-SG FG protocol than in the FH technique (P < .05). The height, length, and depth of the osteotomy and root resection angle were less in the 3D-SG FG protocol than in the FH technique (P < .05). The osteotomy and RER time with the 3D-SG FG protocol were less than the FH method (P < .05). ConclusionsWithin the limitations of this cadaver-based study using denuded maxillary and mandibular jaws, 3D-SG FG protocol showed higher accuracy than FH osteotomy and RER. Moreover, the 3D-SG FG drill protocol significantly reduced the surgical time.

Drilling Response of Carbon Fabric/Solid Lubricant Filler/Epoxy Hybrid Composites: An Experimental Investigation

Carbon-fiber-reinforced epoxy composite (CEC) has gained widespread acceptance as a structural material in various applications. Drilled holes are essential for assembling composite material components. Reducing drilling-induced damage and temperature effects is crucial for improved surface quality and integrity of the drilled composite. In the present work, drilling experiments were conducted on CEC, hexagonal-boron nitride (h-BN) dispersed CEC, and molybdenum disulfide (MoS2) dispersed CEC at three different levels of spindle speed, feed, and drill diameter using solid carbide twist drills. The filler concentrations used in this study were 4, 6, and 8 wt%. Analysis of variance (ANOVA) was used to determine the significance of input factors (feed, spindle speed, drill diameter, and filler concentration) on the drilling responses such as thrust force, temperature, arithmetic mean surface roughness (Ra), and push-out delamination factor (DFexit). The average drilling temperature, Ra, and DFexit of MoS2 dispersed CEC were reduced by 24.7, 46.5, and 11.3%, respectively, when compared to neat CEC. In h-BN dispersed CEC, the average drilling temperature, Ra, and DFexit were reduced by 25.2, 40.9, and 13.2%, respectively, compared to neat CEC. The lubricating properties and high thermal conductivity of filler added to epoxy are responsible for the lower temperature and improved hole surface finish. The improved delamination resistance in filler-loaded CEC is due to the strengthening of the matrix and fiber–matrix interface. Scanning electron microscopy (SEM) was used to examine the morphology of the drilled composite surface. The spindle speed of 5500 rpm, feed of 0.03 mm.rev−1, and filler loading of 4 wt% produced the minimum Ra and DFexit. The response surface method (RSM) was applied to determine the input parameters based on multi-response optimum criteria.

Laser Induced Breakdown Spectroscopy (LIBS) for whole rock geochemistry

To meet the ever-increasing global demand for metals, new mineral deposits need to be discovered. However, as the exploration frontier progressively moves towards deeper buried prospective areas, sampling is becoming costlier and deposit discovery rates are in decline. New technologies and analytical procedures able to deliver fast, reliable, and cheaper samples, analysis, and data, compared to current procedures are therefore, crucial in decreasing the risk of exploration targeting and can represent a step change in mineral exploration. In this study we demonstrate how to emulate laboratory whole-rock geochemical data for major elements (Al, Ca, Fe, K, Mg, Na, Si, and Ti) by averaging LIBS spot analyses performed over single, 1-mm spaced transects, that imitate downhole trajectories, along ~1-meter length drill core intervals for chemically, texturally, and mineralogically diverse rocks. Data was collected using a benchtop prototype LIBS instrument that could be reconfigured to fit within a ≥ 75 mm diameter drill hole. The prototype comprises a customised 8 ns pulsed 532 nm Nd:YAG laser with maximum pulse energy of 40 mJ at 5 Hz; two high-resolution spectrometers that together cover a spectral range from 190 to 830 nm, hence allowing all elements to be analysed; a motorised stage; and optics. Estimated LIBS geochemistry shows strong correlations with laboratory whole rock geochemistry for the selected major elements, particularly for Si, Al, and Na, and to a lesser extent K, although the LIBS estimation can breakdown for elements found in low concentrations (e.g., 0.06 wt%). Factors including the variability in mineralogy and element deportment, or roughness of the analysed surface can result in under- or over-estimation in LIBS whole rock geochemistry. In addition, for more efficient data collection processes, investigations of the optimal number of LIBs spot analysis showed that optimal ~30 to ~560 spot analyses per meter are required to emulate whole rock geochemistry (e.g., 1 % error and 95 % confidence). The strongest influence on the optimal number of LIBS analysis required for estimation of whole rock geochemistry is the range of element concentration and to a lesser extent the number of minerals that host an element as well as grain size. The results of this study show promise in development of strategies for rapid whole rock geochemical analysis down a drill hole.

An investigation of basalt/E-glass hybrid composite pipe on drilling using Box–Behnken design

ABSTRACT This paper discusses E-glass-basalt hybrid composite pipe drilling characteristics effects. FRP is usually applied to commodities and subjected to drilling for various applications. The hybrid composite specimen was fabricated using basalt and E-glass fibers via the filament winding technique with varying process parameters followed by high-temperature curing using a furnace. The drill dimension [D], feed rate [F], and cutting speed [S] are considered input variables of the process parameters. The Box–Behnken design orthogonal array involves 15 runs of experimentation for modeling and data acquisition of the response surface technique (RSM). The delamination factor (Fd) is computed using a simplistic Chen’s one-dimensional equation in the ultrasonic C-scan technique, and the thrust force and the surface roughness responses were resolved over the experiments, and the Regression Prediction Model is constructed and confirmed through confirmation test. In terms of multiple responses of the drilling characteristics on hybrid fiber composite pipe, the drill diameter (4 mm), speed (1000 rpm), and feed rate (50 mm/min) are the optimum process parameters obtained by using the GRA technique. The constructed regression model exhibits a superior level of robustness with R-sq values above 85%. The confirmation experiment indicates that the approximated model is more acceptable, with a mean prediction error of about 3.2%.

Minimum temperature of 31°C was achieved at speed of 186rpm, feed of 0.196 mm/rev, drill diameter of 3.85mm, and drill tip angle of 110°. Response SurfaceMethodology (RSM) was used to develop a mathematical model to predict the type of relationshipbetween inputs and response. It was concluded that the most influencing parameter was drill diameter.

ディープホールドリリング法による溶接部残留応力の高精度測定

This paper presents a method to improve accuracy of measuring through–thickness residual stress for welds through deep hole drilling (DHD) technique. The focus of this study is the effect of dimensions of the hollow cylinder, which is manufactured by drilling and trepanning processes, on residual stress measurement at the welds. First, stress concentration–induced plastic region around a reference (drilled) hole was theoretically quantified according to value of existing stress. The plastic region around the hole is not negligible for the welds at where high tensile residual stress exists. In order to reduce the influence of the plastic region, it is considered effective to set a large ratio of trepanning diameter to drilling diameter. Another noteworthy thing is that weld residual stress is present in a relatively narrow region along a weld line. Then, DHD technique was applied to measure through–thickness residual stress at the welds of melt–run welded–plate specimens under conditions of various drilling and trepanning diameters. These DHD residual stress measurement results were compared with those measured by X–ray diffraction and contour methods and calculated by weld thermal elastic–plastic analysis. As the results, it was shown that through–thickness residual stresses measured by DHD technique were obviously influenced by dimensions of the hollow cylinder. Measurement accuracy becomes higher with increasing the ratio of trepanning diameter to drilling diameter. Meanwhile, trepanning diameter should not be larger than width of generation area of high tensile residual stress to be measured at the welds. It was concluded that a method for determining appropriate dimensions of the hollow cylinder to be drilled and trepanned was successfully proposed to accurately assess through–thickness residual stress at the welds through DHD technique.

Effects of a simplified drilling protocol at 50 rpm on heat generation under water-free conditions: an in vitro study.

In recent years, guided implant surgery has been widely used for the convenience of patients and surgeons. Further streamlining the surgical procedure would make implant surgery more convenient. Low-speed water-free conditions are often used in guided implant surgery. Therefore, in this study, we attempted to confirm once again whether drilling was safe at a low speed without water. The main purpose of this study was to evaluate whether a simplified drilling protocol that omits some intermediate steps in the drilling process was safe from the viewpoint of heat generation. D1 density artificial bone blocks were drilled under 50 rpm, 10 N·cm water-free conditions, and the surface temperature was measured using a digital infrared camera. First, drilling was performed with the sequential drilling method, which is the most widely used technique. Second, for each drill diameter, the temperature change was measured while performing simplified drilling with omission of the previous 1, 2, or 3 steps. In sequential drilling, the heat generated during drilling at all diameters was less than the critical temperature of osteonecrosis (47°C) except for the ⌀2 drill. Statistical significance was observed in all groups when comparing sequential and simplified drilling in the ⌀3.2, ⌀3.8, and ⌀4.3 drills (P<0.001). However, in the simplified drilling procedures, the temperature was below the osteonecrosis threshold temperature (47°C) except for the ⌀4.3 drill with the omission of the previous 3 steps (⌀3.0, ⌀3.2, and ⌀3.8). In general, drilling under low-speed, water-free conditions has shown stable results in terms of heat generation. Simplified drilling showed statistically significantly greater heat generation than sequential drilling. However, most of the diameters and omitted steps seem to be clinically acceptable, so it will be useful if an appropriate selection is made according to the patient's clinical condition.

HYDRO-MECHANICAL DRILLING OF WELLS

The solution to the problems of the construction of deep wells is possible when creating downhole tools on a fundamentally new ideological basis, involving physical principles, technical solutions unconventional in the field of drilling equipment. It is important to take into account the energy resources that increase with depth. Following this concept, based on the tasks of geological exploration, a downhole layout has been developed and introduced into the production of drilling wells, with design features and technological capabilities focused on a comprehensive solution to the problems of well wiring. Structurally, the downhole layout aimed at maximizing the potential energy of the working fluid is universal, designed for drilling wells with core sampling of increased diameter (100 mm or more), and with a solid face. In addition to the outer pipe and core receiver, the downhole layout is equipped with diamond drill heads with a stepped matrix, with a separate system of flushing channels, collectively realizing the effect of hydro-mechanical destruction of rocks. By introducing into the composition of the bottom-hole layout, converting the ascending flow into a rotational-ascending one, the problem of removing sludge from under the end of the stepped matrix is effectively solved. Production tests of the downhole layout with core sampling were carried out at the polymetals deposit of Central Kazakhstan, solid face during drilling of groundwater wells in the territory of the Almaty region. According to the results of production tests, it was found that the hydro-mechanical destruction of rocks is especially effective in combination with diamond drill heads with a stepped matrix. The presence of a turbulator-expander in the bottom-hole layout made it possible to significantly increase the amount of incoming sludge of drilled rock in the well sump, especially when drilling wells with a solid face. In comparable geological and technical conditions of drilling wells, serial core sets HQ with a drilling diameter of 95.6 mm had the following indicators: energy consumption – 2.1-2.4 kW / hour, core yield with a diameter of 63 mm – 93%, specific lumpiness of the core – 5-8 pcs / per linear meter of drilling, drilling was carried out at an axial load of 2200-2500 kgf, rotation speed 500-700 rpm. Similar indicators of the downhole layout: energy consumption – 1.2-1.5 kW / hour, core yield – 98-100% with a diameter of 112 mm, specific lumpiness – 2-3 pieces, axial load – 700-900 kgf, rotation speed – 300-400 rpm.

Experimental Investigation on Drilling of Fiber Metal Laminates Using Grey Based Taguchi Approach

The drilling of multi-material stacks is a complex task for engineers due to their heterogeneous nature. Delamination is the main surface damage involved during multi-material composites drilling leads to workpiece rejection. In this work, the influence of three distinct drill geometries with different diameters and cutting parameters in the drilling have been assessed through the delamination factor.

Analysis of variance has been used to find the effect, percentage contribution, and significance of the process parameters, namely, cutting speed, feed rate, drill bit type and diameter. The focus of this article is to convey multi-objective optimization of CNC drilling parameters using the Grey-Taguchi method to achieve the minimum response in the machining of multi-material composites used in aircraft industries. The hybrid technique’s effective execution aids in the production of high-quality, defect-free holes.

Composite/metal stack materials, which have excellent mechanical properties, are wideyl used in aerospace industry. However, their machining operation is challenging due to two different material. In this study stack materials consisting of CFRP and Al 7075-T6 were drilled with different drilling parematers to investigate delamination defect, thrust force, inner surface roughness of hole and wear of the cutting tool. Cutting speeds of 50 and 200 m/min, feed rates of 0.10 and 0.20 mm/rev were selected as cutting parameters. The materials were drilled respectively in CFRP/Al 7075 and Al 7075/CFRP directions to observe effect of machining direction in the experiments Drilling experiments were carried out with an uncoated 9 mm diameter drill at variable and constant speeds. Experimental results showed that the surface roughness increased with the increase of cutting speed and feed rate, delamination increased in experiments where cutting tool came out of CFRP, thrust force at variable speeds increased and low amount of wear of cutting tool thanks to internal cooling.

Prediction and optimization of temperature in bone drilling based on response surface methodology

Bone drilling is a standard surgical procedure. High drilling temperature can reduce the biological activity of bone tissue, cause thermal damage, and possibly reduce drilling quality. This study was based on the simulation of the surgical drilling process with the finite element method (FEM). The drilling temperature was predicted through the response surface method (RSM) and obtained the minimum temperature and its corresponding drilling parameter combination. In this study, residual and variance analyses were performed on the drilling temperature prediction model and proved that the model fitting effect was good and the reliability was high. Furthermore, this study analyzed the influence trend of three parameters affecting drilling temperature: drill diameter, rotational speed, and feeding speed. It has a specific reference value for orthopedic clinical surgery.
