• This paper deals with the comparison of water-soluble cutting fluids for hobbing with dry cutting in performance, in terms of flank wear, crater wear and finished surface roughness, using TiN and (Al,Ti)N coated high-speed steel cutting tools. The experiments were performed using a fly tool of the same geometry as that of one tooth of a hob on the milling machine. The results helped clarify the following points: (1) The flank wear and the crater wear obtained with the water-soluble cutting fluids are larger than those obtained with the dry cutting, when using both TiN and (Al,Ti)N coated tools at the cutting speed of 117m/min, but in the case of the (Al,Ti)N coated tool at the high cutting speed of 159m/min, they are small when using the fluids. (2) The finished surface roughness when using the fluids is almost larger than that obtained in dry cutting, irrespective of the change in the kinds of coating films and the cutting speeds. (3) At the high cutting speed of 159m/min, the fluid containing the synthetic lubricating additive and the sulfuric EP additive is effective in the cutting performance compared with the dry cutting.
