A description is made to clarify the cutting mechanism of micro drill machining, and the tool dynamometer for micro drill machining, which is a measuring device required for setting the optimum machining conditions. The drill diameters coverd by this tool dynamometer are from 0.08mm to 0.04mm. In order to distinguish the usage in accordance with the size of diameters, two types of tool dynamometers were made experimentally. Tool dynamometer of TYPE- I was made experimentally for micro drills up to 0.08mm in diameter with the exception of 0.04mm in diameter, and micro bearings were employed. Tool dynamometer of TYPE-II was made experimentally for micro drills of 0.04mm in diameter, and pivot bearing were used. Both of the two types of tool dynamometers are markedly characterized by the capability to measure simultaneously the thrust and torque among the fine outting forces generated when machining the micro drills. For the performance evaluation of the tool dynamometers which were made experimentally, calibration was done based on the concept of the newly established JIS Z 9090,and the practicality of these tool dynamometer machining examples.
