Abstract
To produce a chamfer or a keyway on a workpiece, the workpiece is machined with a longitudinal feed following the course of the chamfer or groove. To obtain a clean chamfer or groove in an economic way, machining is effected by a peeling operation by means of a peeling knife, whose broadside forming a cutting edge is aligned transverse to the feed direction during the longitudinal feed, and which is guided parallel to the workpiece surface with a certain cutting depth.
Claims3
A method of producing V-shaped grooves machined in the surfaces of different materials of a workpiece having outer contours, the V-shaped grooves having a predetermined depth relative to the surface, which comprises the steps of advancing a peeling knife in a feed direction along the surfaces, the peeling knife having a broad side forming a V-shaped cutting edge penetrating the surfaces to the predetermined depth, machining the V-shaped grooves with the cutting edge while aligning the cutting edge transversely to the feed direction as the peeling knife is advanced, cutting the outer contours of the workpieces along bottoms of the V-shaped grooves after the grooves have been machined with the peeling knife to produce parts of the workpieces of the same outer contour, and arranging said parts of different materials in an alternating pattern.
