Abstract
An in situ measurement system is established to measure the waviness of rounded cutting edge of diamond tool, into which a capacitive linear variable differential transformer (CLVDT) sensor and a diamond rectangular pyramid probe with an end line length of less than 1.2 μm are integrated. To accurately fit the short-arc cutting edge, a random statistics enhanced least-square circle method is further proposed. Moreover, the rotation error of the air shaft of the planetary lapping machine is measured with consideration of error separation. Finally, in situ measurements are carried out by using the established method to acquire the cutting edge waviness of a newly shaped diamond tool, and off-line measurements are also performed on a surface profiler to verify the in situ acquired data. The results validate that the proposed in situ method is effective to evaluate the cutting edge waviness accurately.
