Description

This paper deals with the influence of water-soluble cutting fluid on tool life (flank wear) of various coated cutting tools and finished surface roughness compared with dry cutting and water-insoluble cutting oil in hobbing. Experiments were conducted by simulating hobbing by fly tool cutting on a milling machine. The following results were clarified. (1) In the conditions of 1-thread and 3-thread hobs, the water-soluble cutting fluid used in the tests prolongs the tool life of TiSiN- and AlCrSiN-coated tools compared with that obtained with dry cutting and the water-insoluble cutting oil. (2) The water-soluble cutting fluid used in the tests is effective for all of various coated tools in the term of finished surface roughness. (3) From the viewpoints of tool life and finished surface roughness, the water-soluble cutting fluid is suitable for TiSiN- and AlCrSiN-coated tools.
