A good numerical control can automatically handle spindle synchronization, gripping, pulling and even parting of the workpiece. The means the control has the power to interpolate the various axes of motion to perform all the these actions, plus has the memory and repeatability to recognize the position of the workpiece in relation to the cutting tool. In the most advanced versions, onscreen simulation will allow a cutting cycle to be displayed in 3D, real-time and actual cutting conditions, although this can (and should) also be completed offline. Doing so ensures better production runs, and allows for better scheduling and even better estimating of job costs and raw material needs. This straightforward counterspindle cycle enables operations to be accom- plished without any additional CNC lan- guage commands and sloping surfaces to be programmed easily. The machining plane can be rotated to the correct ori- entation without the need for either that trusty pocket calculator or CAD/CAM system preparation. On older or less powerful CNC mod- els, code is needed for each plane of motion, even when the shape of the cav- ity is identical. Newer CNC technology enables that code to be automatically stored in the CNC memory and be replicated and re-oriented to another plane of motion. The upside is a considerable sav- ings in time with no loss of part integrity. In the end, machining molds with complex inside contours with relief cuts or deep pockets becomes much easier on a machine with a more sophisticated CNC. A geometric track- ing function can even handle the identification of residual material automatically.
