Process and device for adjusting reamers and the like

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 including a shaft, a cutting blade disposed on the 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 of the cutting blade and the guide point of the guide element being disposed on a cutting plane of the cutting tool, the process comprising the steps of:

• clamping the cutting tool in a toolholder mounted on a coordinate slide;
• utilizing a camera-equipped measurement arrangement including a camera, a measurement slide supporting the camera, and a computer connected to the camera;
• traversing a distance with the measurement arrangement between the guide point and the cutting point, including the steps of:
• moving the measurement slide and the camera thereon to the guide point for acquiring the guide point on the camera;
• fixing the guide point as a zero reference position II on the measurement arrangement;
• and
• moving the measurement slide and the camera thereon to the cutting point as a measurement position I for acquiring the cutting point on the camera;
• 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. utilizing the measurement arrangement by acquiring the tilt angle on the camera;
• converting the effective tilt angle .alpha. into an effective tilt diameter D1 defined in a direction parallel to the effective tool diameter D at predetermined distance L from the cutting plane measured in a direction parallel to the rotational axis of the shaft;
• adjusting the effective tool diameter D to the stipulated tool diameter by manipulating the cutting tool;
• and
• adjusting the effective tilt angle .alpha. to the stipulated tilt angle by adjusting the effective tilt diameter D1 to a stipulated tilt diameter.
