Scanning probes
Scanning probes can acquire several hundred surface points each second, enabling measurement of form as well as size and position.
Scanning probes can also be used to acquire discrete points in a similar way to touch-trigger probes.
A range of solutions is available, suitable for all sizes and configurations of CMM.

Scanning explained
Scanning provides a fast way to capture form and profile data from prismatic or complex components.
While touch-trigger probes gather discrete points on the surface, scanning systems acquire vast quantities of surface data, providing a clearer picture of the form and shape of the workpiece. Scanning is therefore ideal for measurement applications where the form of a feature is a significant element of the overall error budget, or where complex surfaces must be inspected.
Scanning requires a fundamentally different approach to sensor design, machine control and data analysis.
Renishaw scanning probes feature innovative, lightweight passive mechanisms (no motors or locking mechanisms) that exhibit a high natural frequency, making them suitable for high speed scanning. Isolated optical metrology systems measure the deflection of the stylus directly (not via stacked axes within the probe mechanism) for better accuracy and faster dynamic response.
How does a scanning system capture and analyse surface data?
Scanning probes provide a continuous deflection output that can be combined with the machine position to derive the location of the surface. When scanning, the probe stylus tip is brought into contact with the feature and then moved along the surface, gathering data as it moves. Throughout the measurement, it is necessary to keep the deflection of the probe stylus within the measurement range of the probe.
For best results, this demands close integration of the sensor and machine control, as well as sophisticated filtering algorithms to convert the resultant data into useable surface information. Scanning drive algorithms can adapt to the contours of the part, changing the scanning speed to suit the rate of curvature (going faster on flatter surfaces) and adjusting the rate of data capture (taking more data where the surface changes quickly).
Motorised and automated probe heads
Motorised heads enable automated, repeatable re-orientation of probes to allow access to features on all faces of the part, improving the capability of the CMM and maximising productivity.

Indexing heads
Motorised indexing heads are designed to position the probe at one of 720 positions, so probing can be carried out at many angles. The repeatability of the head allows to recall those positions without the need for requalification, saving operator time and applying the probe to the surface at the best angle for the most accurate result.
Servo heads
Motorised servo type heads provide almost unlimited angular positioning and are ideally suited to horizontal arm CMMs.
