Hello,
At the moment we have a couple of CMM's with Renishaw PH10M heads and either a TP20 or a TP200 module.
We are thinking about buying a new CMM. We are planning to scan some products.
Hexagon recommended their own rotating head type HP-L. This looks quite fancy, except that I have heard that for calibration it needs
25 hits for each angle being used. If that is so, then we will lose plenty of time calibrating instead of measuring. At the moment we calibrate using 5 hits on the calibration sphere. (Minimal I know, but it seems to work for us)
The difference is 5 times longer!!
I have 3 questions:
Is the 25 hits correct?
If we were to buy a Renishaw SP25 how many calibration hits are needed on the sphere? I asked Renishaw, they replied that it is up to the software.
Concerning the HP-L or the SP25
Is it not possible to calibrate the first position with 25 hits, then the other angles scan the sphere?
Regards
John
