Abstract

Dimensional repeatability and predictability of tolerance levels are two of the most fundamental requirements of today's automated manufacture leading towards unmanned manufacture. Regarding continuous batch production, when Computer Numerical Control (CNC) machines are utilized, the certainty of achieving these is rather poor, despite the high order of accuracies claimed by CNC machine manufacturers. The aim of the present thesis is to investigate the likely causes for the poor performances in CNC machining operations and to propose some control measures to eliminate or at least reduce the shortcomings.
