NUMERICAL CONTROLLER HAVING FUNCTION OF SUPERIMPOSING SUPERPOSITION CYCLE SYNCHRONIZED WITH PERIODIC OPERATION CYCLE

摘要

A numerical controller controls a machine tool which carries out machining by moving a workpiece or a tool using a periodic operation cycle for repeatedly executing the same operation. The numerical controller stores command data of each execution period of a superposition cycle superimposed with the periodic operation cycle. Command data sets of the superposition cycle are synthesized every execution cycle in synchronization with execution timing of the periodic operation cycle.
