Where can SP80 be used? (3)
•DIGITISING Applications
–Capturing large amounts of data about an unknown surface
–Creation of CAD models
–Uses many of the same techniques as scanning
•
•
•REVERSE ENGINEERING Applications
–Digitised data can be exported to CAD for   reverse engineering purposes
–Used to generate a machining program for          re-manufacture
Like scanning, digitising is best performed using a scanning probe since the amount of data required is very high. Whilst discrete point measurement techniques can be used, these are very much slower.

Digitising uses many of the techniques needed for scanning, except that the motion of the CMM is controlled in a different manner.

On described parts, the probe can move in a pre-defined path, accommodating any surface deviations. By contrast, on an unknown part the probe is moved within a pre-defined area and the probe deflection vector is used to determine which way to move the CMM to keep the probe stylus in constant contact with the surface.

Digitising is used for re-manufacture and reverse engineering where a master part must either be replicated or converted into digital form.
