Abstract:
A method for cutting a workpiece with a tool having reversible cutting tips, each having a cutting wedge (2) defined by a first face (3) and a first flank (4), said cutting wedges (2) having a clearance angle of 0Â° to 3Â°, said method comprising the steps of:providing a coating (8) on a surface of said first flank (4), said coating (8) comprising wear-resistant cutting elements (17) embedded in a binding agent (16), wherein said binding agent (16) forms an elastic matrix allowing said wear-resistant cutting elements (17) to elastically yield; removing cuttings (7) from a workpiece (6) by said cutting tips (1); immediately after the step of removing, smoothing a crack surface (20) of the workpiece (6), created by removing cuttings (7), with said wear-resistant cutting elements on said surface of said first flank (4) so that the workpiece (6) is roughed and smoothed in a single machining operation.
