Predictions of Tool Wear by Estimating Weight Loss During Polymer Composites Processing

Abstract

The main criterion for wear of the tooltip when processing polymer composites is a technological criterion, namely the conventional amount of wear on the tool flank face. The cutting edge wear is asymmetrical, and it was assumed that during the wear process, the initial tip of the sharpened tool moves along the rank surface. Then, in the plane of the tool top, you can calculate the change in area and find the weight loss over a certain period. A geometric model was developed that allows you to relate the amount of tool weight loss and the classical determination of the wear value on the flank face. Using experimental data on fiberglass processing, the relationship between the conditional amount of wear on the back surface and the loss of weight and the change in the shape of the cutter for various technological parameters of processing ’, ’ feed, speed, and depth of cutting ’, ’ was established. Generalized dependencies were obtained, which connect the amount of weight loss by the tool with technological parameters and processing duration.
