Method for measuring a program-controlled machine tool
First Claim
1. A method for measuring a program-controlled machine tool using a measuring sphere, the machine tool having a controller with stored target values, the method comprising:
- positioning a measuring sphere on a machine part of the machine tool;
moving a sensing element installed in the machine tool to a selected initial position;
repeatedly moving the sensing element until it contacts various points on the surface of the sphere;
calculating the spatial position of the center of the sphere based on the obtained measurement values; and
comparing the calculated spatial position of the center of the sphere with the target values stored in the controller.

Abstract
A method for measuring a program-controlled machine tool using a measuring sphere. According to this method the measuring sphere having known dimensions is positioned on a machine part. A sensing element installed in the machine is moved to a selected initial position in which it is located approximately 10 mm above the vertex section of the sphere. Then the sensing element is repeatedly moved until it contacts various points on the surface of the sphere, and the coordinate values of those points of contact are input into the controller. Thereafter the spatial position of the center of the sphere is calculated and compared with target values stored in the controller.
