Method and apparatus for setting moving data in a machine tool

摘要

A contour shape of a desired shape of a workpiece at section along a predetermined axis is divided into machining units. Each of the machining units includes a plurality of inflection points including a machining start point and a machining end point. Machining data at least necessary for performing machining is set for each of the machining units. Arrival times at the inflection points are calculated based on the machining data, and a position of at least one of the workpiece and the tool is calculated for each of the inflection points. For each of the machining units, a rotation angle position of the workpiece corresponding to the arrival time is set as an accumulated count value.
