Adaptive Control Constraint System through Current Monitoring of Spindle in NC Lathe Process

NC 선반공정에서 주축 전류 모니터링을 통한 구속적응제어 시스템

In order to regulate cutting force at a desired level during NC lathe process, a feedrate override Adaptive Control Constraint system was developed. Nonlinear model of the cutting process was linearized as an adaptive model with a time varing process parameter. Performance of the ACC system was confirmed on the NC lathe equipped with the developed NC system through a large amount of experiment.
