Abstract

Relevance Modern requirements for turning accuracy of parts during turning are constantly increasing. In order to provide them, in addition to using modern CNC machines and tooling, it is necessary to minimize errors arising during the operation of the machine drives (main and feed drives), as well as the cutting tool that is used during the process. This task can be carried out using specialized tracking systems for controlling the electric drive of a CNC lathe. The use of the control system allows you to control nondeterministic cutting parameters and ultimately provide the required amount of roughness. Aim of research The main aims of the research develop a model of the tracking system for controlling the feed and main motion of the CNC lathe. Research methods The control system model is synthesized using the MATLAB SIMULINK program. Results As part of the study, the MATLAB SIMULINK software package was used to develop a model of the tracking system for controlling the feed motors and the main motion of the CNC lathe. As a result of the operation of the servo control system, it has become possible to determine the values of non-deterministic cutting parameters, which will ensure the accuracy of processing the surfaces of the workpiece with a minimum error value.
