The block transitions are only constant in the velocity, while acceleration of the
participating axes can be in jumps at block transitions.
Block transitions have continuous acceleration. This ensures both smooth velocity and
acceleration of all axes at block transitions.
The compression that uses a lot of computation time and memory space is optimized
regarding surface quality and speed. COMPCAD should only be used if measures to
improve the surface cannot be taken by the CAD/CAM program in advance.
