78Abstract In this research the effects of production factors on wear of two types of gear hobs were investigated These factors consist of hob materials heat treatment and grinding process Both of gear hob materials were high speed steel HSS AISI M2 and ASSAB ASP30 The evaluation of topography and microstructures hardness profile and phase detection were performed by optical and scanning electron microscopy microhardness tester and X ray diffraction respectively Effect of heat and high temperature of grinding on topography microhardness profile and wear of the HSS machining insert were studied The results show that gear hobs material produce by powder metallurgy ASP 30 has better properties than M2 steel in the end of heat treatment and the best microstructure and properties in tempering process obtain in the range of 540 560 C after four times
