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.

Method for producing a surface that is intended to be comprised in a coupling for use at chip removing machining, comprising:
- forming at least three groove sets in a surface at an end of a cylindrical member for contacting another surface provided with grooves, wherein each groove set has a plurality of elongate grooves extending in a main direction, at least one groove of the plurality of grooves of each groove set having a length more than twice a width of the groove, and wherein main directions of adjacent groove sets intersect, each groove set being produced in a separate cutting operation;
- during each cutting operation, machining an equal part of the surface;
- and
- during an end phase of at least one cutting operation, overlapping a groove set being produced with at least one adjacent groove set.

- forming at least three groove sets in a surface at an end of a cylindrical member for contacting another surface provided with grooves, wherein each groove set has a plurality of elongate grooves extending in a main direction, at least one groove of the plurality of grooves of each groove set having a length more than twice a width of the groove, and wherein main directions of adjacent groove sets intersect, each groove set being produced in a separate culling operation;
- during each cutting operation, machining an equal part of the surface;
- and
- during an end phase of at least one cutting operation, overlapping a groove set being produced with at least one adjacent groove set.
Surface for use in a rotating tool for chip removing machining, comprising a surface having a center hole, at least three groove sets for contacting another surface provided with grooves, each groove set being adjacent at least two other groove sets of the at least three groove sets, wherein each groove set has a plurality of elongate grooves extending in a main direction, at least one groove of the plurality of grooves of each groove set having a length more than twice a width of the groove, and the main directions of adjacent groove sets intersect, adjacent groove sets overlap, and each groove set covers an equal part of the surface.
