Determining appropriate and Geometric BODY SET for parts and semi-on working tree. Create a 3D model.
Creating a blank (rough stock) with those allowances which will be model.
Going to the machine mode of CAD/CAM system and set tool parameter, which will perform roughing model.
Defining the strategy of machining operations, which are determined semi-alone model, the machining allowance, tolerances, cutting speed and feed motion of the machine tool path.
Setting the proper parameters of the other cutting tools which will perform profiling.
