Claim Text:
1. Measuring device for in-process measurement of test pieces during a machining operation on a machine tool, comprising: a) a base body; b) a measuring head which is movable relative to the base body of the measuring device between a neutral position and a measuring position in which the measuring head is in measuring contact with a test piece; c) an angle sensor which operates in a machine reference-free manner provided and associated with the measuring head for detecting an angular position of the measuring head relative to the test piece, during a measuring operation, the angle sensor includes an acceleration sensor, and the acceleration sensor determines the static acceleration of the measuring head with reference to gravitational acceleration; d) the angle sensor detects changes in the angular position of the measuring head relative to the test piece; e) the angle sensor includes an accelerometer which delivers at least one output signal; f) an evaluation device which determines the angular position of the measuring head relative to the test piece as a function of the at least one output signal of the accelerometer delivered to the evaluation device; and g) the angle sensor is connected to the evaluation device.
