“…At the same time, the process of cutting polymer composite materials is accompanied by the same phenomena as when cutting metals, i.e., chip formation, force, thermal phenomena, and intense wear of the cutting tool are observed. Each of the listed phenomena differs from similar phenomena during metal cutting, therefore, to control the processing of polymer composite materials, it is necessary to evaluate the thermophysical phenomena that occur during their cutting [2].…”

The Purpose of the paper. The study of thermal physics of the process of drilling polymer composite materials based on the capabilities of the engineering package Comsol Multiphysics. Determination of the values of temperatures arising in the cutting zone when drilling with a cutting tool in polymer composite materials, namely, in carbon fiber. Establishment of the depth of heat propagation inside the workpiece from the edge of the formed hole of the polymer composite material. In this work, the Fourier heat equations are used. Numerical simulation of the drilling process wascarried out in the engineering package COMSOL Multiphysics. A technique for modeling thermal effects during drilling of carbon fiber reinforced plastics in the Comsol Multiphysics environment has been developed. As a result of computer calculation, temperature fields were obtained at the edge of the carbon fiber reinforced plastic hole. The study of the thermal state of carbon plastics has been carried out. On the basis of the conducted research, it was revealed that the temperature during drilling of carbon fiber reaches 650 K. The distance over which heat spreads from the edges of the hole into the workpiece for carbon fiber is 3 mm. The developed technique for modeling the thermal impact of cutting polymer composite materials in the COMSOL Multiphysics environment can significantly simplify complex analytical calculations, help to avoid overheating of the part during drilling, which improves the quality of processing.
