... Capturing the in-process workpiece geometry generated during machining is an important part of tool path verification and increasingly the physics-based simulation of cutting forces used in Virtual Machining. Swept volume generation is a key supporting methodology that is necessary...

... 13 06 2012 This paper is intended to contribute to ongoing research [1–3] in geometric modeling of the virtual machining. In geometric modeling the tool paths are verified by performing the machining simulations and also the cutter workpiece engagements (CWEs) are extracted. CWE...

... 21 03 2011 Virtual Machining (VM) is the use of computers to simulate the physics of machining processes. It can be used to effectively identify problems in machining complicated workpieces and in optimizing processes. At the heart of VM is the ability to predict the cutting forces...
