Abstract: Currently, it is impossible to imagine production without cutting tools with interchangeable polyhedral plates. The life of a cutting tool depends on many factors, for example, on the geometric and structural features of the cutting part, processing modes, properties of the tool material, types of reinforcing coatings, etc. The objective of a number of our studies is to increase the life of the cutting tool by renovating polyhedral plates using grinding. Grinding can be performed along the contour, along the back or front surface of the polyhedral plate. In order to obtain a satisfactory result, it is necessary to work out the issue of fastening and correct basing of the plate in the device, taking into account the further increase in automation of this fastening. In this scientific article, the methods of basing the cutting plates in the device are considered. The following methods of fastening polyhedral plates in a contour grinding device have been studied: fastening with a clamp centered on the chamfer; fastening with a clamp; fastening with a screw; fastening with a collet; fastening with a screw centered on the sleeve. The calculation of the basing error for the considered types of fasteners of cutting plates has been performed. The conclusion is made about the expediency of using each type of fasteners based on calculations.
