Controller for controlling servo motor and spindle motor

摘要

In a controller (10) a contour machining is performed through synchronous control of a mechanically movable portion (servo axis) driven by a servo motor (17x, 17z) and a main shaft (spindle axis) driven by a spindle motor (19). The position of the servo axis and the position of the spindle axis are collected at the same timing for each predetermined cycle and are stored. The stored position data of the servo axis and the spindle axis are converted to obtain a machining contour shape data, and the shape obtained is displayed on a display device of a personal computer (22) or the like. <IMAGE>
