| Abstract:
A process for adjusting an effective tool diameter D and an effective tilt angle .alpha. of a cutting tool to a stipulated tool diameter and a stipulated tilt angle, respectively. The cutting tool includes a cutting blade disposed on a shaft and defining a cutting point and a cutting edge tilted by the effective tilt angle with respect to a rotational axis of the shaft, and a guide element disposed on the shaft opposite the cutting blade and defining a guide point and a guide line, the cutting point and the guide point being disposed on a cutting plane of the cutting tool. The process includes the steps of utilizing a measurement arrangement including a camera and a measurement slide supporting the camera; moving the measurement arrangement for acquiring the guide point on the camera; and moving the measurement arrangement to the cutting point for acquiring the cutting point on the camera. The process further includes the steps of determining the effective tool diameter D by determining the distance travelled by the measurement slide between the guide point and the cutting point; determining the effective tilt angle .alpha. by acquiring the tilt angle on the camera; converting the effective tilt angle .alpha. into an effective tilt diameter D1; adjusting the effective tool diameter D to the stipulated tool diameter; and adjusting the effective tilt angle .alpha. to the stipulated tilt angle by adjusting the effective tilt diameter D1 to a stipulated tilt diameter. |
