High-Speed Machining for CNC Milling Simulation Using CAM Software

Abstract

The two types of computer numerical control (CNC) machining are conventional and high-speed machining. In this work, the high-speed machining is investigated. The term ‘high-speed machining’ typically refers to milling machining at high levels of rotational speed, feed rate, and/or material removal rate. High-speed machining technology sometimes uses high revolutions per minute (rpm) rate and has a small step-over with significantly increased feed rate. Thus, the high-speed machining is suitable for replacing an existing machining process with increased flexibility and efficiency. Therefore, a gap of knowledge for high-speed machining information exists and must be explored on the basis of in-house resource availability. This work presents an investigation of high-speed machining for CNC milling simulation using Mastercam software. This work aims to study the difference between CNC machining strategies for high speed and conventional machining on a 3D part model containing a pocket with a protrusion island. The high-speed machining is compared with conventional machining using the same software to ensure the reliability of the former. Furthermore, the toolpath strategies for cutting methods are compared.
