Abstract

Relevance The process of processing a part by cutting is constantly complicated. This is due to the fact that as a result, it is most often necessary to obtain a part of difficult profile shape, and its surfaces must correspond to a high quality of accuracy with a minimum error. The process of turning complex parts is implemented under the conditions of using undetected cutting indicators. In order to control and influence their changes, it is advisable to use a specialized roughness control system. Aim of research The main aims of the research develop a fuzzy logic roughness management system using the MATLAB SIMULINK software package. Research methods To achieve computer-automated modeling, control system development methods were used. In particular, the MATLAB SIMULINK software package was used. Results As part of the study, MATLAB SIMULINK synthesized a system for controlling roughness when machining a part with a CNC lathe. The simulated process of the system has shown the effectiveness of its application, which is expressed in the accurate receipt of the required roughness parameters during part processing. The required values are achieved by adjusting the longitudinal feed drive and the speed of the cutting tool.
