METHOD OF CONTROLLING POWER OF CNC LASER MACHINE TOOL.

摘要

A method of controlling the power of a CNC laser machine tool in which a numerical controller (CNC) and a laser machine tool are combined together. The instructed output power value is read from a memory (11) and is given to an output power control means through a pre-processing means (12). An output power control means (17) decreases the output power depending upon the decrease in the actual speed obtained from an actual speed calculation means (16). Therefore, the machining precision is improved and the thermal effect is reduced in the corner portions.
