Abstract
A coordinate measuring machine for measuring coordinates or properties of a workpiece includes an extended stylus. The extended stylus includes an extension element and a connection element. The extension element includes a carrier portion mounted at the connection element so as to be rotatable about an axis of rotation. The extension element includes, on a side remote from the connection element, a shaft portion that is aligned so as to deviate from the axis of rotation. The coordinate measuring machine includes a measurement head to which the extended stylus is attached. The measurement head is configured to measure deflections of the stylus resulting from contacts of the extended stylus to the workpiece.
Claims20
A coordinate measuring machine for measuring coordinates or properties of a workpiece, the coordinate measuring machine comprising:
- an extended stylus including an extension element, a probing contact element, and a connection element, wherein the extension element includes:
- a carrier portion mounted at the connection element so that the carrier portion is rotatable about an axis of rotation relative to the connection element, and
- on a side remote from the connection element, a shaft portion that is aligned so as to deviate from the axis of rotation, wherein the probing contact element is arranged at an end of the shaft portion and lies on the axis of rotation and wherein the carrier portion and the shaft portion are fixedly connected to each other;
- and
- a measurement head to which the extended stylus is attached,
- wherein the measurement head is configured to measure deflections of the extended stylus resulting from contacts of the extended stylus to the workpiece.
An extended stylus for a coordinate measuring machine for measuring coordinates or properties of a workpiece, the extended stylus comprising:
- a connection element;
- a probing contact element;
- and
- an extension element including:
- a carrier portion mounted at the connection element so that the carrier portion is rotatable about an axis of rotation relative to the connection element, wherein the carrier portion extends from a first end proximate the connection element to a second end remote from the connection element, and
- a shaft portion that is aligned so as to deviate from the axis of rotation and that is connected to the second end of the carrier portion,
- wherein the probing contact element is arranged at an end of the shaft portion and lies on the axis of rotation, and
- wherein the carrier portion and the shaft portion are non-rotatably connected to each other, and
- wherein the extended stylus is configured to be attached to a measurement head of the coordinate measuring machine.
An extended stylus for a coordinate measuring machine for measuring coordinates or properties of a workpiece, the extended stylus comprising:
- a connection element;
- a probing contact element;
- and
- an extension element including:
- a carrier portion configured to rotate with respect to the connection element about an axis of rotation, wherein the carrier portion includes a first end connected to the connection element and a second end remote from the axis of rotation, and
- a shaft portion including a first end fixedly connected to the second end of the carrier portion and a second end connected to the probing contact element, wherein the carrier portion and the shaft portion are arranged to locate the probing contact element on the axis of rotation throughout rotation of the extension element and wherein the extended stylus is configured to be attached to a measurement head of the coordinate measuring machine.
