Abstract
This paper presents the development of the contact-type displacement probe with low measuring force for the profile measurement of the cutting edge on-machine and non-damaging. This probe is consisted of a triangulation-based laser displacement sensor and both-ends supported leaf spring, on which a stylus tip will be mounted. The displacement of the stylus tip can be measured by detecting the deflection of the leaf spring with the laser displacement sensor. The probe is mounted on the linear stage to scan the cutting edge. To realize the large measurement range and low measurement force, the probe tip is contacted intermittently in the vertical direction. The low measurement force of less than 0.1 mN can be achieved. The measurement accuracy is evaluated, and then, the profile of the sharpened edge is measured by utilizing the developed probe system.
