Problems solved by technology

However, sensors with high mechanical response bandwidth and very high natural frequency have a very limited operating range
For example, a sensor with a frequency response above 50Hz may have an operating range of less than 500um

Embodiment Construction

[0047] A coordinate measuring machine (CMM) is shown in FIG. 1 and includes a mechanical table 4 on which a workpiece 8 can be placed. An analog probe 5 with a deformable stylus 9 and workpiece contact tip 12 is mounted on quill 6 of machine 4 . The quill 6 and the probe 5 can move along the X, Y and Z directions under the action of the X, Y and Z drives of the CMM, and the X, Y and Z drives of the CMM are controlled by a computer. The CMM's X, Y and Z scales display the instantaneous coordinates of the position of the quill shaft on which the probe is mounted in three dimensions. Signals from the probe indicating probe stylus deflection are combined with readings from the CMM's X, Y, and Z scales to calculate the position of the stylus tip and thus the surface of the workpiece.

[0048] The computer contains programs that cause the probe to scan the surface of the workpiece.

[0049] The probe will now be described in more detail with reference to FIG. 2 . The probe 5 has ...

Abstract

The present invention provides a measurement probe (5) which comprises a housing (16) for mounting on an arm (6) of a coordinate positioning apparatus (2) and a stylus (10) mounted on a stylus support member (28). The stylus (10) and the stylus support member (28) are deflectable with respect to the housing (16). A first transducer system (40-48) measures movement of the stylus support member (28) relative to the arm (6) of the coordinate positioning apparatus (2). A second transducer system (38) measures movement of the stylus tip (12) relative to the stylus supporting member (28). A measurement of total stylus deflection is achieved by combining data from the first and second transducer systems.

Description

technical field [0001] The present invention relates to a scanning probe applied to a coordinate positioning machine, such as a coordinate measuring machine, a machine tool, a manual coordinate measuring arm or an inspection robot, to determine the position or profile of a surface. Background technique [0002] A known type of coordinate positioning machine comprises, for example, a support arm for movement in mutually perpendicular directions relative to a table on which a workpiece can be supported, and sensors for measuring the reference or base position of the arm relative to the table . Scanning probes generally consist of a relatively fixed structure, such as a housing, contacts supported on a bracket assembly for three-dimensional movement relative to the fixed structure, and contacts for measuring relative to a reference position on the fixed structure position sensor. [0003] In use the fixed structure of the probe is fixed to the arm of the machine and in normal...
