Abstract
This paper outlines a simulation study to investigate the correlation between radial depth of cut (RDOC) and axial depth of cut (ADOC) in 4 axis machining processes. Computer-aided Manufacturing (CAM) plays a crucial role in simulating cutting operations before the real process executed. Several cutting parameters can be analysed through effective CAM program to predict the outcomes. However, an efficient program required skilled operator to develop the process planning. Besides, a standard CAM system has limited capabilities to handle repetitive simulation due to unavailable function to support the analysis. In this study, the combination of RDOC and ADOC is analyses on different parts features consist of planar surface and non-planar surface. Several set of pairing percentages between RDOC and ADOC are used in the simulation program to analyses the cutting operations. In order to perform the simulation, a customized program was developed in NX CAM system to assist the routines. It capable to generate machining data files from each simulation and assess the total volume removed. A pairing set with high volume removal is denoted as an optimum value and will be chosen as a cutting parameter in finishing operation. Generally, ADOC has a significant effect compared to RDOC in terms of total volume removed from the workpiece.
Highlights
An optimum selection of cutting parameter is highly contributes to the increasing of productivity and decreasing of production cost
The simulation results has shown that the developed program manages to build a complete machining operation and successfully minimizes the time spent for process planning up to 79% compared to conventional approach
After machining simulation were executed using 3 different models, the findings show a trend where highest volume removed is achieved by using high Radial depth of cut (RDOC) and low Axial depth of cut (ADOC) parameter
Summary
An optimum selection of cutting parameter is highly contributes to the increasing of productivity and decreasing of production cost. Modern industries require a digital management platform that capable to storing uniform data related to product design, process design and manufacturing processes This system is developed to provide solutions by combining all digital information in a single database. The Master Model application manage to reduce the product life cycle time and percentage of error generation during NX parts assembly information updating processes. Standard user form was used as an interface in macro method and able to help user to interact with CAD model It contains a labeled text box and a commands button to start the design process. The simulation results has shown that the developed program manages to build a complete machining operation and successfully minimizes the time spent for process planning up to 79% compared to conventional approach
