The reference material (in Europe) for comparison is the leaded free-cutting brass CuZn39Pb3.This reference material is assigned the machinability index 100. The machinability index is an index of the productivity that can be achieved with a material in series production, expressed as a direct comparison with another material. Machinability indices for copper alloys are issued by the German Copper Institute and by material suppliers. Criteria for dividing the machinability into 3 main groups: Tool life Chip formation Cutting forces Surface quality The classification was made primarily in regard to the expected chip formation. However, for the difficult-to-machine materials in Group III the high level of wear on the tool is the key feature for the classification. Machinability group I Copper materials containing lead, tellurium or sulphur, homogeneous or heterogeneous structure. Very easy to machine. Machinability group II Copper materials with higher tensile strength and better cold forming characteristics, long chipping. Good to moderate to machine. Machinability group III Copper materials with homogeneous structure. Good cold forming characteristics lead to poor chip formation (long tough chips) and high tool wear. Difficult to machine. 153
