Diagnosing of the Glass Fiber Reinforced Polymer Material High Performance Drilling Process State

The article presents the results of works on the analysis of using cutting forces and torque measurements to determine the state of dry fiberglass matrix polyester resin composite high performance drilling process. The research and analyzes were carried out for the different states of tool state and the process state itself. GFRP - Glass Fiber Reinforced Polymer was used to perform the experiment. As a result of the conducted analyzes, it was determined that booth the forces and torque generated in drilling process can constitute a good diagnostic signal, on the basis of which it is possible to conclude about the state of the process and tool.
