Analisis Efektivitas Mesin Bordir Komputer Menggunakan Metode Overall Equipment Effetivenes (Oee) dan Six Big Loses pada UD. Jadi Gumilang Sukorejo

The garment company UD. Jadi Gumilang is a home-based industry located in Mojotengah Village, Sukorejo District, Pasuruan Regency, East Java. UD. Jadi Gumilang engages in the production of bags, clothes, uniforms, and embroidery, which are produced only when there are customer orders. Frequent damage to the computerized embroidery machine occurs because operators do not perform routine maintenance as per the garment's regulations. To address this issue, the Overall Equipment Effectiveness (OEE) value was calculated to analyze the major factors causing downtime. OEE itself is the result of multiplying the variables of Availability (90%), Performance (95%), and Quality (99%). After calculating the OEE value, the six big losses values were calculated to identify the highest losses that cause low OEE values. Then, from the highest loss values, a fishbone diagram (cause-and-effect diagram) analysis was conducted to identify the factors causing damage to minimize the recurrence of similar issues in the future. The results of the study show that out of the 2 computerized embroidery machines, one machine has an OEE value below 85%, which is the computerized embroidery machine 1 (84.64%). From this value, the six big losses calculations reveal that the largest loss is idling and minor stoppages losses, amounting to 20.02%. After conducting a fishbone diagram analysis, the factors causing idling and minor stoppages losses were identified as Human, Machine, Method, and Raw Material. Suggestions to prevent idling and minor stoppages losses include frequently cleaning the production area after production, regularly lubricating the machine to prevent wear, always checking the machine's condition before use, and others.

Optimal design and experiments of a novel bobbin thread-hooking mechanism with RRSC (revolute–revolute–spherical–cylindrical) spatial four-bar linkage

Abstract. To solve the problem of low supply of bobbin thread and frequent bobbin changes existing in current embroidery machines, a novel bobbin thread-hooking mechanism with an RRSC (revolute–revolute–spherical–cylindrical) spatial four-bar linkage is proposed which can achieve a large number and continuous supply of bobbin thread. Based on the analysis of the chain stitch formation principle, the design requirements for motion trajectory and posture of the hooking mechanism are proposed. The methods of direction cosine matrix and mechanism identity condition are applied in kinematics modeling and analysis of the RRSC mechanism. The optimization design model and computer-aided software are developed, then the human–computer interaction optimization method is used to obtain optimal solutions to meet working requirements. The physical prototype is machined and a test bench is built. The virtual simulation and prototype high-speed camera kinematics tests are conducted. The results verify the correctness of mechanism design and show good application feasibility of the mechanism.

From Smartphone to Fabric: Mobile Embroidery Programming

Equipping the next generation with skills in science, technology, engineering, art, and mathematics (STEAM), including computational thinking and graphic design, is crucial. Yet it can be difficult for young people to sustain interest in technology – particularly for girls due to persistent differences in their socialization. Project-based learning combining hands-on experience with fashion and design offers a promising means of sparking and sustaining interest in technology. Mobile embroidery programming is one such project, but there are still challenges to be overcome in transferring embroidery files to programmable embroidery machines as part of school courses or coding weeks. This report presents a device we developed that facilitates wireless file transfer. The embroidery file, encoded in a common format like DST, can be wirelessly transferred to the embroidery machine. We optimized the process of the embroidery workflow in a series of 14 workshops. Furthermore, we tested additional hardware for embroidery file transfer based on Raspberry Pi on a group of 18 participants. Our findings suggest that wireless file transfer may be useful with other maker devices such as 3D printers. The results will benefit schools, maker spaces, code clubs, and individual users seeking to engage in STEAM activities.

Adaptive tactile interaction transfer via digitally embroidered smart gloves

Human-machine interfaces for capturing, conveying, and sharing tactile information across time and space hold immense potential for healthcare, augmented and virtual reality, human-robot collaboration, and skill development. To realize this potential, such interfaces should be wearable, unobtrusive, and scalable regarding both resolution and body coverage. Taking a step towards this vision, we present a textile-based wearable human-machine interface with integrated tactile sensors and vibrotactile haptic actuators that are digitally designed and rapidly fabricated. We leverage a digital embroidery machine to seamlessly embed piezoresistive force sensors and arrays of vibrotactile actuators into textiles in a customizable, scalable, and modular manner. We use this process to create gloves that can record, reproduce, and transfer tactile interactions. User studies investigate how people perceive the sensations reproduced by our gloves with integrated vibrotactile haptic actuators. To improve the effectiveness of tactile interaction transfer, we develop a machine-learning pipeline that adaptively models how each individual user reacts to haptic sensations and then optimizes haptic feedback parameters. Our interface showcases adaptive tactile interaction transfer through the implementation of three end-to-end systems: alleviating tactile occlusion, guiding people to perform physical skills, and enabling responsive robot teleoperation.

Machine embroidery of light-emitting textiles with multicolor electroluminescent threads.

Advances in electroluminescent threads, suitable for weaving or knitting, have opened doors for the development of light-emitting textiles, driving growth in the market for flexible and wearable displays. Although direct embroidery of these textiles with custom designs and patterns could offer substantial benefits, the rigorous demands of machine embroidery challenge the integrity of these threads. Here, we present embroiderable multicolor electroluminescent threads-in blue, green, and yellow-that are compatible with standard embroidery machines. These threads can be used to stitch decorative designs onto various consumer fabrics without compromising their wear resistance or light-emitting capabilities. Demonstrations include illuminating specific messages or designs on consumer products and delivering emergency alerts on helmet liners for physical hazards. Our research delivers a comprehensive toolkit for integrating light-emitting textiles into trendy, customized crafts tailored to the unique requirements of diverse flexible and wearable displays.

Stretching the Limits of MRI-Stretchable and Modular Coil Array Using Conductive Thread Technology.

We propose a modular stretchable coil design using conductive threads and commercially available embroidery machines. The coil design increases customizability of coil arrays for individual patients and each body part. Eight rectangular coils were constructed with custom-fabricated stretchable tinsel copper threads incorporated onto textile. Tune, match, and detune circuits were incorporated on the coil. A hook-and-loop mechanism was used to attach and decouple the modular coils. Phantom and in vivo scans at various anatomical flexion angles were acquired to highlight performance, and a temperature test was performed to verify safety. In vivo MRI experiments demonstrate high sensitivity and coverage of each anatomy. As the coils are stretched, the sensitive volume increases at a rate of 10.93 mL/cm2. The SNR reduction of a single coil was greater during compression than when stretched, but this did not affect image quality for the array. The modularity of the array allows for adaptability for any anatomy with simple on-demand adjustment to the number and position of coil elements. The images demonstrated high sensitivity and coverage of the stretchable array for various anatomies and flexion angles. Stretching the coils increases the sensitive volume, allowing for a larger region to be effectively imaged. The resonance shift and SNR decrease during stretch and compression support further investigation of methods to reduce frequency shift in stretchable coils. The proposed array design allows for highly stretchable, flexible, modular, and conformal patient-centered coils that allow for increased imaging quality, greater comfort, and rapid production.

Design of ergonomic chair for the embroidering processes of the bag making (case study: CV. Pinus Bag’s Specialist)

Physical activities related to work activities in production operators are jobs that need attention—operator activity on a CV. Pinus Bag’s Specialist engaged in convection, especially in the embroidery process, is done using a machine; the design will be sent from the computer to the embroidery machine monitor. The operator on duty would set the fabric to be embroidered, thread the needle, frequently change the thread, and correct the twisted thread. Meanwhile, the risk level of the embroidery workers has not been evaluated, and no unique chairs have been designed for it. Then, this study will assess the risk level of employees working in the embroidery department and create ergonomic chairs that are comfortable, durable, and robust. The risk level of workers is assessed using REBA. It uses anthropometric data from 2 workers who work in the embroidery section at CV. Pinus Bag’s Specialist, Yogyakarta, Indonesia. The anthropometric data come from buttocks-popliteal length (seat length), popliteal height (chair height), hip width in the sitting position (chair base width), and side shoulder width (chair back width). And shoulder height in the sitting position (backrest height). After that, the chair is designed with the help of the application. The study indicates that most of the work activities in the embroidery process require corrective action. In addition, the chair design used for the embroidery process is adjustable, comfortable, durable, and strong. The seat height is adjustable with an operator and an embroidery table. Ultimately, the embroidered chair reduced work risk from medium to work postures with low work risk.

The Longest (s, t)-Path Problem on O-Shaped Supergrid Graphs

The longest (s,t)-path problem on supergrid graphs is known to be NP-complete. However, the complexity of this problem on supergrid graphs with or without holes is still unknown.In the past, we presented linear-time algorithms for solving the longest (s,t)-path problem on L-shaped and C-shaped supergrid graphs, which form subclasses of supergrid graphs without holes. In this paper, we will determine the complexity of the longest (s,t)-path problem on O-shaped supergrid graphs, which form a subclass of supergrid graphs with holes. These graphs are rectangular supergrid graphs with rectangular holes. It is worth noting that O-shaped supergrid graphs contain L-shaped and C-shaped supergrid graphs as subgraphs, but there is no inclusion relationship between them. We will propose a linear-time algorithm to solve the longest (s,t)-path problem on O-shaped supergrid graphs. The longest (s,t)-paths of O-shaped supergrid graphs have applications in calculating the minimum trace when printing hollow objects using computer embroidery machines and 3D printers.

NEW SOLUTIONS IN THE PRODUCTION OF COMPOSITES - MECHANICAL PROPERTIES OF COMPOSITES REINFORCED WITH TECHNICAL EMBROIDERY AND WOVEN FABRIC MADE OF FLAX FIBERS

The main purpose of the article is to present the new possibilities of producing natural fiber composite reinforcement. In this case, a computer embroidery machine by ZSK type JCZA 0109-550 was used. A technical embroidery with a stitch length of 2 mm was made on the machine. The embroidery was made of flax roving with a linear density of 400 tex. The woven fabric was made of the same flax roving as the embroidery, with a surface mass of 400 g/m2. Composites were then produced from the technical embroidery and woven fabric using the infusion method with epoxy resin. The individual configurations differed from each other in the orientation of the roving in the embroidery samples. Samples for tensile strength and tensile elongation tests consisted of 4 layers, while samples for the DCB test consisted of 6 layers, with the addition of a separating foil between the 3rd and 4th layer. Composites were then subjected to strength tests - tensile strength, tensile elongation and DCB test (Double Cantilever Beam test), on the INSTRON machine. During the action of force along the direction of the fibers, composites containing technical embroidery as reinforcement were characterized by higher strength than composites containing woven fabric as reinforcement. Additionally, embroidery is a barrier to the formation of interlayer cracks. Technical embroidery is made on the basis of Tailored Fiber Placement (TFP) technology. This technology allows optimizing the mechanical values of the composite reinforcement.

Image Processing Based Pattern Recognition and Computerized Embroidery Machine

In the last decades, embroidery getting much attention in industries and academics. Although the technique is very old, it is still very much adopted. The current era of machine learning and smart devices makes this method even more attractive, easy to adopt and high accuracy. The proposed research work aims to highlight the implementation of new smart devices in this field, and the work is based on microcontrollers. Adopting the proposed work will be very easy and feasible to transform from the old sewing machine to a new smart method. Using smart devices, it is very easy and precise to get the embroidery fulfilling the user's demands. It gives simple raster images, which are used to convert into digital images to portray any new product. The current work is a novel idea of generating simple images rather than complicated ones, which are difficult to draw. In our method, we introduce the digitization process to input any image file used for vectorizing raster images, where vector images can easily convert into a DST embroidery file, a commonly used embroidery format originally from Tajima. It also has a Gcode file. The machine runs on a Gcode file which can be easily generated and runs on a product.

Domination and Independent Domination in Extended Supergrid Graphs

Supergrid graphs are derived by computing stitch paths for computerized embroidery machines. In the past, we have studied the Hamiltonian-related properties of supergrid graphs and their subclasses of graphs. In this paper, we propose a generalized graph class for supergrid graphs called extended supergrid graphs. Extended supergrid graphs include grid graphs, supergrid graphs, diagonal supergrid graphs, and triangular supergrid graphs as subclasses of graphs. In this paper, we study the problems of domination and independent domination on extended supergrid graphs. A dominating set of a graph is the subset of vertices on it, such that every vertex of the graph is in this set or adjacent to at least a vertex of this set. If any two vertices in a dominating set are not adjacent, this is called an independent dominating set. Domination and independent domination problems find a dominating set and an independent dominating set with the least number of vertices on a graph, respectively. The domination and independent domination set problems on grid graphs are known to be NP-complete, meaning that these two problems on extended supergrid graphs are also NP-complete. However, the complexities of these two problems in other subclasses of graphs remain unknown. In this paper, we first prove that these two problems on diagonal supergrid graphs are NP-complete, then, by a simple extension, we prove that these two problems on supergrid graphs and triangular supergrid graphs are also NP-complete. In addition, these two problems on rectangular supergrid graphs are known to be linearly solvable; however, the complexities of these two problems on rectangular triangular-supergrid graphs remain unknown. This paper provides tight upper bounds on the sizes of the minimum dominating and independent dominating sets for rectangular triangular-supergrid graphs.

Comparison of Mechanical Properties of Composites Reinforced with Technical Embroidery, UD and Woven Fabric Made of Flax Fibers.

The main purpose of the article is to present the possibilities of producing composite reinforcement with the use of a computer embroidery machine. The study below presents the results of strength tests of composites containing technical embroidery, woven fabric, and UD fabric as the reinforcement. Each of the samples was made of the same material-flax roving. The samples differed from each other in the arrangement of layers in the reinforcement. The composites were made using the infusion method with epoxy resin. The embroidery was made on a ZSK embroidery machine, type JCZA 0109-550. A total of 12 types of composites were produced and tested. The test material was subjected to strength tests-tensile strength, tensile elongation, and shear strength, on the INSTRON machine. As the research showed, the use of technical embroidery as a composite reinforcement increases its tensile strength. Furthermore, the use of embroidery is a vertical reinforcement of the composite and prevents the formation of interlayer cracks. The technology of technical embroidery allows for optimizing the mechanical values of the composite reinforcement.
