From Great Sim:
Machining Simulation 2011 simulates CNC machines and system panel on computer, which can familiarize CNC learners with CNC machine and avoid damage of fixture and cutting tool by eliminating CNC learners' errors of programming and detecting for clashes in advance. The 3D simulation of the work piece and NC machine tool enable you to visualize the machining exactly as it occurs on the shop floor and corrects tool path errors before machining, potential crashes/collisions, gouges, and over/undercutting.
What's new in this version:
Version 220.127.116.11 fixed of G73 without d value for clearance.
