EXPERIMENTAL STUDY ON DIMENSIONAL AND GEOMETRICAL ACCURACY ACHIEVED AT THE CONTOURING MILLING OF 6082 ALUMINUM ALLOY

摘要

In this paper it is presented an experimental study concerning the accuracy achieved at the exterior contours finishing at work pieces made by 6082 aluminum alloy, on a vertical machining centre YMC 1050 with three axes. The chosen profile is compound of straight and arc portions, in order to be properly obtained on these machines, where we can determine dimensional, linear and angular, deviations and geometrical, shape, sense of direction and position, deviations. The accuracy of the manufactured surfaces was analyzed from the cutting speed and feed influence point of view, which were varied at two level values and by the milling method, climb or conventional millin.
