Stages of modeling diamond grinding of a hard-alloy tool for processing composites
In this paper, the specifics and complexity of cutting processing of nonmetallic composite materials related to their unique combination of properties in the example of milling are considered. It is noted that a tool equipped with a carbide cutting element for the processing of polymer composites should have a quality cutting blade in order to provide the desired shape and technical characteristics of the treated surface of the parts. The problem of forming a cutting wedge with the required parameters for the processing of nonmetallic composites is considered. A technique for modeling diamond grinding of a hard alloy using the Johnson-Cook breakdown measures is presented. The proposed method allows to evaluate the grinding conditions and tool material, from the point of view of the occurrence of fractures along the cutting edge. Conclusions and prospects of further research are formulated.
