Cutting Performance of High Speed Steel Hobs with Different Coating in Dry Hobbing
This paper explains the results of a systematic dry hobbing experiment performed on a general mechanical transmission type of hobbing machine. The HSS hobs with different combinations of coat materials and coating states display significant variations in tool life. A TiN coating hob demonstrates the best cutting performance although the coating cost is the lowest. Furthermore, some meaningful discussions related to the dry hobbing mechanism are also presented.
