CNC 레이저 가공기의 가공 정밀도 개선을 위한 입력성형 적용

Abstract

This study presents an application of input shaping to a CNC laser processing machine to enhance performance. An effective command generation method is developed to reduce tracking errors and vibrations during the XY stage of laser processing. This study then conducts simulations with an analytical model of the stage in which anisotropic characteristics are considered. Simulation results revealed that two-mode input shapers should be employed during command generation to reduce tracking errors caused by input shaping. Experiments were successfully performed to show the enhanced processing quality with the CNC laser processing machine on two typical laser marking processes: linear marking and a combined process of linear and circular marking. The simulations and experiments showed that the proposed command generation method is very useful for improving the processing precision of the CNC laser processing machine.
