SELECTING EQUIPMENT SOLUTION FOR THE CHARACTERIZATION OF THE FRICTION DRILLING PROCESS

A process currently under researchers' attention in terms of making holes is the so-called friction drilling. The process is based on pressing a conical-shaped tool, driven in rotation, into the workpiece to be drilled. The analysis of the process highlights that there will be a variation of the axial force to the physical-mechanical properties of the workpiece material. To highlight the axial force variation, it was necessary to select, among several alternatives, a device that would make this possible. In this sense, the method of analytic hierarchy process was used. It was possible, thus, a justified selection of the device intended to allow obtaining additional information on the friction drilling process.
