IMPROVEMENT OF TECHNOLOGICAL PROCESS OF MECHANICAL PROCESSING WITH THE DESIGN OF THE CUTTER FOR FINISH TURNING
The technological process of mechanical processing of composite materials is considered. A brief description of composite materials, their physical and mechanical properties, and their structure is studied. Depending on the state of the surface layer, the cutting tool required for mechanical processing is considered. The rationale for the need to improve the design of the cutting tool is given. The design of the cutting head has been developed for the cutting process. It consists of a rough and finishing incisors. The values of the design parameters of the tool head are considered and selected. The optimal cutting depth for the finishing tool has been determined. We experimentally selected the geometric parameters of the finishing tool, the purpose of which is to provide the required quality of processing. Using experiments, the values of the angle of deviation of the main cutting edge from the horizontal plane were found. The design of the finishing tool, which largely eliminates the disadvantages of processing, is described in detail. The appearance of a leading crack when turning with a finishing tool is excluded.
