An integrated size and roundness adaptive control system for the plunge grinding process

A time variant, roundness based adaptive size and roundness control system is presented for the plunge grinding process which avoids the need for a large data processing capacity and compares favourably in performance with the large and expensive control system previously developed and therefore improves the prospect of industrial use. The non-linear control functions and adaptive model are presented and analysed. The hardware of the integrated, low cost system and the software algorithms used to reduce the computational power requirements are discussed and the results of grinding experiments are presented.
