Abstract
A laser power controlling method in which a laser output is controlled by an NC instruction as a function of an instruction regarding the moving speed of a mechanical system. The moving speed instruction is inputted to a simulator approximated to the mechanical system with a first-order or second-order function, and based upon the results operated by the simulator, a laser instruction value is generated, so that synchronism between the moving speed of the mechanical system and the laser output control is assured. Therefore, the moving speed of the mechanical system is synchronized with the power of the laser beam projected onto a workpiece to thus enhance cutting performance.
Claims2
A laser power controlling method in which a laser output is controlled by an NC instruction as a function of an instruction regarding the moving speed of a mechanical system, the method comprising the steps of:
- providing an instruction regarding moving speed to a simulator approximated to said mechanical system with a first-order or second-order function;
- and
- generating a laser output instruction based on the result obtained by said simulator,
- whereby synchronism between the moving speed of the mechanical system and the laser output control is assured.
