Abstract
Compreg – machinability during drilling. The article presents the results of tests of machinability of compreg. Machinability was evaluated during drilling. The value of the axial force and cutting torque for 7 variants of feed per revolution and the quality of the drilling process were examined. Cutting forces were measured using piezoelectric Kistler sensor and Labview software. The quality was determined on the basis of digital photos taken using macro lens, two quality indices were calculated. It turned out that the assessment of machinability during drilling requires an analysis of axial force and cutting torque. One of the analyzed quality indicators observed outside the nominal diameter of the hole, was strongly dependent on feed per revolution. The impact of feed on the second indicator was much less clear.
