A SEMINAR ON

ADAPTIVE CONTROL MACHINING

ABSTRACT

Adaptive control system is a logical extension

of the CNC-mechanism. In CNC mechanism the cutting speed and feed rates

are prescribed by the part programmer. The determination of these operating

parameters depends on the Knowledge and experience regarding the work

piece, tool materials, coolant conditions and other factors.

By contrast in adaptive control machining, there is improvement in

the production rate and reduction in the machining cost as a result of

calculating and setting of optimal parameters during machining. This

calculation is based on measurements of process variables in real time and

followed by a subsequent on-line adjustments of the parameters subjected to

machining constraints in order to optimize the performance of the overall

system.
