Abstract
<jats:p>The initial prerequisites for the development of technology for turning welded parts are determined, which include the calculation of allowances and boundary dimensions of the product in accordance with technological transitions and the thick-ness of the welded coating. An approach to setting the depth of cut is proposed, which ensures that the coating layer on the machined part has the best and most stable properties, which gives the product better performance, in particular, greater wear resistance. In general, the average depth of cut can be determined using the curve of the relative bearing surface of the coating profile, and, taking into account the Hirst method, the variable part of the depth of cut during coating processing can be determined through the fractal dimension of the surface profile. Some approaches to determining the cutting speed based on the requirements for ensuring the quality of the deposited coating layer and the stability of the cutting tool, as well as the geometric parameters of the tool, taking into account the properties of the material being processed, are considered.</jats:p>
