The newly developed cutting force and temperature measuring system with high response speed and fine resolution can monitor cutting process as well as, tool wear during high-speed endmilling of hard materials. The system enables us to preciseiy determine a transient cutting'force and temperature action which. is generated by each cutting edge of an endmill tools with various rake angles and helix angles. It is found that the cutting force and temperature in high-speed endmilling are sensitive to the helix angle, rake angle and tool wearing process. When the helix angle and rake angle are 60 degrees and - 15 degrees respectively, the cutting force and the flank wear of each cutting egde generated is smaller than those for other angles of helix and rake.
