The 3vm.mch default 3-axis vertical mill machine is retrofitted during this session to provide A axis rotary functionality. The shape of various machine
16、 components are also changed to support the A-axis addition and provide more accurate collision detection. The step at the end of the session shows how to save the machine configuration in a Machine file. A User file containing a reference to the Machine file is also saved enabling VERICUT to be eas
