Abstract: The machine tool controller uses a microprocessor (5) which accepts data on both the profile of the finished piece and on the blank from which the piece is machined, and stores both these sets of data in two memory zones.  The microprocessor program then processes the profile data to remove data which presents a concave part of the finished profile to a third memory zone, and places the remaining data representing the concave profile in a fourth memory.  The tool is then controlled so that it makes maximally effective passes to reducc the blank profile to the finished form, using the stored data on the differences between the two profiles.
