Research on drilling of Ni-based powder metallurgy superalloys
The application of Ni-based powder metallurgy superalloys materials was limited for its difficult-to-machine, such as excessive tool wear, frequent tool change, short tool life, low productivity, and large amount of power consumption etc.So the studying of Ni-based powder metallurgy superalloys drilling process becomes extremely important.This paper mainly introduces the research status of drilling of Ni-based powder metallurgy superalloys materials and through synthesize considering cutting force and cost effective, we determined the optimal of cutting tool materials is carbide YG8 twist drill.The optimal parameters of drilling of Ni-based powder metallurgy superalloys: cutting speed of 15rn/min, feed per tooth of 0.02mrn/r.When the superalloys material is machined by standard twist drill, it is always appearing the failure modes of drilling.
