Coordinate measuring machine for determining spatial coordinates on a measurement object
First Claim
1. A coordinate measuring machine for determining spatial coordinates on a measurement object, comprising:
- a probe head having a body part, a coupling part moveable relative to the body part, a probe tool arranged on the coupling part, and a probe head sensor system designed to detect a position of the coupling part relative to the body part, anda frame structure designed to move the probe head relative to the measurement object,wherein the probe tool has at least one stylus for making contact with the measurement object and has a rotating plate via which the stylus is rotatably coupled to the coupling part in order to establish a defined orientation of the stylus relative to the coupling part, andwherein at least one roll motion projection is formed on the body part, with the rotating plate being configured to roll along the roll motion projection as a result of a defined movement of the coupling part relative to the body part, thereby allowing to set the defined orientation of the stylus.

Abstract
A coordinate measuring machine for determining spatial coordinates on a measurement object has a frame structure on which a probe head is arranged. The probe head has a probe head sensor system, a body part and a coupling part which can move relative to the body part. The frame structure is designed to move the probe head relative to the measurement object. The probe tool has at least one stylus for making contact with the measurement object, and also has a rotating plate. The stylus is coupled to the coupling part by means of the rotating plate, such that it can rotate. At least one roll motion projection is formed on the body part. The rotating plate can be rolled along this roll motion projection by means of a movement of the coupling part in order to set a defined orientation of the stylus.

18. A method for determining spatial coordinates on a measurement object, comprising the steps of:
-
providing a probe head having a body part, a coupling part moveable relative to the body part, a probe head sensor system for detecting a position of the coupling part relative to the body part, and a roll motion projection, providing a frame structure designed to move the probe head relative to the measurement object, providing a probe tool coupled to the coupling part, said probe tool comprising at least one stylus for making contact with the measurement object and a rotating plate via which the stylus is rotatably coupled to the coupling part, bringing the rotating plate into contact with the roll motion projection, moving the rotating plate along the roll motion projection by means of a movement of the coupling part relative to the body part in order to set a defined orientation of the stylus relative to the coupling part, touching a measurement point on the measurement object by means of the stylus, and determining spatial coordinates of the measurement point as a function of the position of the probe head relative to the measurement object and as a function of the defined orientation.
