Proc. ASME. IDETC-CIE2012, Volume 2: 32nd Computers and Information in Engineering Conference, Parts A and B, 751-760, August 12–15, 2012
Paper No: DETC2012-70550
... 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...

Proc. ASME. IDETC-CIE2011, Volume 2: 31st Computers and Information in Engineering Conference, Parts A and B, 805-815, August 28–31, 2011
Paper No: DETC2011-48668
... 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 geometry is a key input to force calculations and feed rate scheduling in milling...

Proc. ASME. IDETC-CIE2010, Volume 3: 30th Computers and Information in Engineering Conference, Parts A and B, 363-372, August 15–18, 2010
Paper No: DETC2010-29003
... 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 generated as the tool...
