Cutting tools in finishing operations for CNC rapid manufacturing processes: simulation studies

By Muhammed Nafis Osman Zahid, Keith Case and Darren M. Watts

Abstract

This is a conference paper. The conference website is at: http://www.solent.ac.uk/conference-centre/events/icmr-2014/icmr-2014.aspxCNC machining has been widely used in producing metal parts with high accuracy and reliable \ud quality. A distinct process planning approach that utilizes an indexing device to hold the workpiece \ud has extended CNC applications into the realm of rapid manufacturing (CNC-RM) processes. This \ud study improves the implementation of this technology by providing a methodology for integrating the \ud tools into finishing processes. It aims to enhance the process efficiency by minimizing the stair-casing\ud effect of layer removal and so improve the quality of machined parts. In order to achieve this, \ud finishing operations are executed using different types of end mill tools to cater for specific surfaces. \ud Simulations are carried out to verify the method and implications. The findings indicate the \ud advantages of the approach in terms of cutting time and the minimisation of excess volumes left on \ud parts. Using different cutters for finish cuts improves the capabilities of CNC machining in rapid \ud manufacturing applications
