Abstract: As a result of high pressure and temperature and the speed of relative movement, the contact surfaces of tools deteriorate during operation. The low dimensional stability of a tool is one of the reasons for the degradation of processing accuracy. Due the stability of this low-dimensional tool, surface treatment operations with precise dimensions are inefficient and expensive. This work presents methods for the stability improvement of end measurement tools. Three practical examples for engineering applications are presented along with relevant equations. Furthermore, the locating chart of the tool on the machine and work surfaces on the cut surface and edge was designed. A scheme to obtain a hole with a constant diameter in case of tool deterioration is also presented. The results show that differential methods significantly increase the service life of tools beyond their dimensional stability. Moreover, differential methods are simple and cost-effective.
