Fixing VA11 calibration artefact and VA90 to CMM
The VA11 calibration artefact is designed to be fixed securely to the bed of the CMM to allow accurate and repeatable calibration of the RVP
system components. The diagrams below show how to fix the VA11 to the bed of the CMM.
1. Locate an appropriate threaded hole in the bed of the machine.
2. Position the artefact plate above the threaded hole.
3. Screw the correct cap head bolt through the hole into the threaded hole on the machine. The supplied washer can be used to correctly fit
smaller diameter bolts.
4. Tighten with a hex wrench.
5. Attach the calibration pillar to the kinematic mount. Integral magnets will secure it in place. Polarisation of the magnets will ensure the
pillar is fitted in the correct orientation.
6. For use with ACM, VA90 can be fitted to the VA11 kinematic mount and the calibration pillar fitted instead to the kinematic mount on the
VA90.
Securing the pillar / VA90
The VA11 pillar and VA90 can optionally be secured to the baseplate or each other using the supplied bracket and screws.
1. Fix the VA11 baseplate to the bed of the CMM before securing the pillar or VA90.
2. Position the bracket with the curved face towards the pillar.
3. Attach the bracket to the baseplate or VA90 using the supplied M2 cap head screw and tighten with a hex wrench.
4. Screw the M2 shoulder bolt through the bracket into the pillar or VA90 and tighten with a hex wrench. Ensure the bolt is not overtightened,
it should float within the bracket so as not to affect the kinematic location of the pillar or VA90.
