Method and apparatus for a numerically controlled industrial machine

摘要

A numerical controller for an industrial machine such as a robot and an assembling system utilizing plural robots. The numerical controller controls movements of plural movable portions of the industrial machine by a synchronous control in which plural movable portions are moved in a synchronized manner. Based on an operational program, the numerical controller identifies a movable portion or movable portions which must be moved independently from other movable portion. The identified movable portion or portions are moved by an independent control. On the other hand, movable portions which are not designated are moved by synchronous control. Further, plural groups of movable portions may be formed for the synchronous control. In this case, movable portions in each group are controlled in a synchronized manner independently from other groups.
