This paper deals with the influence of hob geometry, rake angle and relief angle, on tool wear reduction effect of lubricating additives in cutting oils for bobbing and effect of the additives for improving of finished surface roughness. Experiments were carried out using a fly tool. It was revealed that among the additives used in these experiments, sulfur type's sulfurized fatty oil showed a best performance in terms of an extension of tool life and an improvement of surface roughness for almost of rake angles, relief angles and at all cutting speeds tested. Especially, it was obvious that the sulfurous EP additive is effective for the hob having the geometry of rake angle of 0゜ and relief angle of 12゜. The use of sulfurized fatty oil as an additive is very effective for environmental pollution control and for improving the safety of the operator.
