PROGRAM INVESTIGATING DEVICE FOR NUMERICALLY CONTROLLED WORKING DEVICE

摘要

PURPOSE:To easily find out an unsuitable NC program step by providing a shape display control means, an indicating means and a step display control means to a numerically controlled working device. CONSTITUTION:When a program is investigated, the shape display control means displays the shape of a work on a display means according to an NC program. Then, an investigated point is indicated with the indicating means while the displayed shape is observed. Then, the step display control means displays a step of an NC program corresponding to a point indicated by the indicating means on the display means. In this way, which is the step of the NC program corresponding to the investigated point in the work shape can be found out.
