RESEARCHES ON DRILLING MACHINABILITY OF SOME SINTERED MATERIALS

摘要

In this paper, are presented, in the first part, the methodology to establishment the machinability, using the drilling process, for some materials obtaining through powder metallurgy process. In the second part are presented the experimental results concerning the evaluation of the machinability for these materials through the cutting efforts and tool life. It is been study the influence of the cutting fluids on the machinability.
