METHOD OF PREPARING NC DATA FOR CUTTING GROOVES.

摘要

A unit normal vector (N) is found at a position (Pe) at which the groove cutting is finished after the NC data for cutting have been prepared. A displacement vector is found by the multiplication of a designated displacement (da) and unit normal vector. NC data for escapement are prepared for moving the tool (TL) from the position (Pe) to a point defined by moving vector.
