Embodiment Construction

[0014] figure 1 is a diagram illustrating various typical components of a metrology system 1 including a general-purpose coordinate measuring machine providing a context for the application of the fundamental principles disclosed herein. Certain aspects of metering system 1 are further described in US Pat. No. 8,438,746. The metrology system 1 may include: a coordinate measuring machine main body 2; a motion controller 3 which controls the drive of the coordinate measuring machine main body 2; an operation unit 4 for manually operating the coordinate measuring machine main body 2; and a host computer 5 which issues commands to the motion The controller 3 also executes processing such as shape analysis of the workpiece 10 (object to be measured) arranged on the coordinate measuring machine main body 2 . A representative input unit 58 and output unit 59 are connected to the host computer 5 like the display 5D.

Abstract

A method of manually controlling the motion of a coordinate measuring machine (CMM) is disclosed. The method may include: providing at least one guide element motion tracking sensor; defining a guide element active tracking volume relative to one of the guide element tracking sensor and a portion of the CMM; placing the guide element in the active motion tracking volume; position; and move the measurement pointer of the CMM in response to the tracked position (eg, track position changes). The method may further include detecting a tracking motion activation trigger indicator or condition, and operating the CMM to move the CMM according to the tracking motion after the tracking motion activation trigger indicator or condition is detected and according to the condition that the guiding element is positioned in the active tracking volume part of the measuring detector.

Description

technical field [0001] The present invention relates to metrology systems and in particular to methods for manually controlling the motion of a coordinate measuring machine. Background technique [0002] Certain metrology systems, such as Coordinate Measuring Systems (CMM's), can be used to obtain precise measurements of inspected workpieces and can be controlled at least in part by inspection operations of workpiece characteristics that have been programmed on a computer. An exemplary prior art CMM is described in the U.S. In Patent No. 8438746, the entirety of which is incorporated herein by reference. As described in Patent No. 8438746, a CMM includes a detector for measuring a workpiece, a motion mechanism for moving the detector, and a motion mechanism for controlling the motion mechanism. controller. [0003] A CMM including a surface scanning measurement probe is described in US Patent No. 7,652,275, which is hereby incorporated by reference in its entirety. After s...
