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 hi

The study of residual stresses in metal parts can be performed by making slits where such stresses are assumed to exist. Measuring the width of the slits can provide information on the type and size of residual stresses. The slits must be made by mac
