Embodiment Construction

[0065] figure 1 An exemplary embodiment of a gantry coordinate measuring machine 1 (CMM) according to the invention is depicted, the coordinate measuring machine 1 comprising a base 5 and a frame structure for connecting a probe head 13 to the base 5, the frame structure comprising a relative Several frame assemblies 7, 9-11 that move with each other. The first frame part 7 is a gantry with two gantry arms connected at their upper ends by a bridge part 9 . Driven by a drive mechanism (not shown), the frame assembly 7 is movable along the longitudinal sides of the base 5 . This direction corresponds to the first direction X. The movement of the frame assembly 7 is performed by, for example, a toothed rack attached to the base 5 which meshes with a pinion on the frame assembly 7 .

[0066] The second frame assembly 10 (rack) is movably arranged on the bridge portion 9 of the frame. Movement of the second frame assembly 10 is also achieved by eg a rack and pinion. Vertical ...

Abstract

Method for providing information about a sensor chain of a coordinate measuring machine is provided. The coordinate measuring machine comprises a drive mechanism for moving a tool carrier relative to a base for approaching a measurement point. The CMM also comprises the sensor chain carried by the tool carrier and comprising an arrangement of sensor chain components providing a particular sensor configuration for measuring the measurement point, and a camera for providing an image of at least a part of the sensor chain. The method further comprises capturing an image of at least a part of the sensor chain, deriving at least one sensor chain property from the image by image processing, comparing the sensor chain property with reference data which relates to a set of known sensor chain components and using information relating to the identified at least one sensor chain component to establish a part program to be executed so as to measure the object.

Description

[0001] This application is a divisional application of the original patent application number 201510244432.1 (application date: April 07, 2015, title of invention: method for generating information about a sensor chain of a coordinate measuring machine). technical field [0002] The present invention generally relates to a method of collecting information about a sensor configuration of a coordinate measuring machine (CMM) by means of a camera and a database of reference data, wherein images of the sensor configuration are acquired and processed. Background technique [0003] It is common practice to inspect the workpiece after production on a coordinate positioning device such as a coordinate measuring machine (CMM) to check the correctness of predefined object parameters, such as the size and shape of the object. [0004] On a conventional 3D coordinate measuring machine, the tool holder is supported to move along three mutually perpendicular axes (along the X, Y and Z dire...
