Self-tuning control of the milling cutting process in industrial CNC machines

Abstract

Adaptive control in machining systems leads to an increased production rate as well as tool breakage prevention.Nevertheless, most achievements in adaptive control for cutting processes are limited to laboratory environments; they are seldom to be implemented directly in CNC machines. By decoupling the whole machining system into the time-invariant servo system and the time-varying cutting process, this paper presents a systematic approach to realize self-tuning control in a personal computer along with the CNC conmller successfully. In this paper, satisfactory experimental results have proven that this developed technique is feasible for manufacturing industry.
