ABSTRACT:
In a method for producing a surface that is intended to form part of a coupling for use in chip removing machining, the surface includes a number of groove sets to allow locking by shape against another surface provided with grooves. Each groove set has a main direction, and the main directions of adjacently situated groove sets intersect. The number of groove sets are at least three, each groove set is produced in a separate cutting operation, and an equally large part of the surface is machined during each cutting operation. A surface that is intended to form part of a coupling for use in chip removing machining is also disclosed.
