ADAPTIVE CONTROL FOR MACHINE TOOLS

Abstract

Adaptive Control (AC) of machine tools is a recent development in production engineering 'which aims at performing the cutting operation more efficiently. Usually feeds and/or speeds are adaptively controlled in accordance with the data obtained by sensing process parameters such as tool tip temperature, cutting force, spindle torque, vibrations etc. By virtue of its ability to economize metal tutting process, AC call be expected to play a vital role in machine tool industry. AC systems applied to machining processes such as turning, milling, grinding are discussed in this report. The principle, types and advantages of AC systems are also described.
