Renishaw TP20 modules

constadin
Hello,

In my company in TIGO SF machines we use TP20 modules in various configurations. Normally they use low force modules when a 0.5 tip is mounted and a 6way module for all the rest. The TP20 machines as compared to TIGO machines with X1C head are way...way less repeatable/accurate.

I read in the specs that 6way are generally less precise than standard force modules and also more expensive. I would like to replace 2 probes specifically 1 with 6way that is in star formation (length of probes out of specs with 40 mm vertically and 1 tip at 30 mm horizontally) and a low force module that is in star formation with 0.5mm tips left right and a pointing (x+) 2x40 mm tip. I know both probes are out of specs but replacing them with standard force modules does not seem to improve the results by a lot (at least some preliminary testing).

So i would like more experienced user to let me know if using low force modules in star configs is a good idea (out of specs according to renishaw), how can I mount a 0.5mm in a star probe if a low force module is needed and finally what are your opinions of 6way probes for none special applications needing measures in Z-

Thanks in advance!

  • The thing is that the rack with the 6ways and in general the whole build of the probes is how I found them. We have many programs, validated since many years ago that work like this and any change for example going from 40mm to 30mm would require work not worth having. I know for a fact that we don't measure in Z- by pulling so 6way modules are not needed and for me it was a mistake done many many years ago by the person that build the rack.

    The issue now is that I seem to be unable to get good results with a 0.5 tip if not used in a low force module, while having a low force module in conjunction with a star formation is a no go per renishaw.
