In this paper we describe a newly developed cutting force measuring system with high response speed and fine resolution. It can monitor the cutting process using various tools as well as the tool wearing process during high-speed endmilling of hard steel materials. The system enables us to precisely determine a transient cutting force action which is generated by each cutting edge of various helix angled endmill tools rotated at speeds of 40000 rpm. It is found that the cutting force and its waveform in high speed endmilling are sensitive to by the helix angle and tool wearing process. When the helix angle is 45 degrees, the cutting force and the flank wear of each cutting edge generated is smaller than those for angles of 15 and 30 degrees.
