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!

  • 6 way probes are the only ones that are designed to be "pulled" to get a reading. All other forces are only meant to be "pushed."

    With that said I would not recommend changing your 6 way star probe, made to take a Z minus reading to a standard force one.

    I have a probe that is basically an "L" for measuring in Z minus, on a 6 way TP20. We used a 50mm carbon fiber extension, to a 5 way star, and then a 2x20. It calibrates and measures just fine.

    Maybe your build is too heavy for the 6 way. Try taking the 40mm off, and see how the 30mm does just by itself. (if I read your description right, sounds like that was two tips on one probe.)
