  • Touch Force

    How do I determine the actual touch force of the probe to the part during measurement?

    What kind of Machine/probe are you using?

    BS
    Windows 7
    Pc-Dmis 2015
    Global Performance 7-10-7

      I have a B&S MicroXcel DCC machine, with a PH10T / TP20.
      Thanks!

        Are you talking touch speed or the velocity it takes to set off the probe.

          Do you mean how do you adjust touch speed or how can you measure the grams of force it takes to trigger the probe?

          Touchspeed is in settings or parameters. I use 1% for everything. They sell gages for measuring the force. You also can look at the specs for the probe modules have (TP20, TP200 , Etc.)
          When in doubt, post code. A second set of eyes might see something you missed.

            I would like to know the velocity / force that triggers the probe. I am working on a project now, where the impact of probe contact may have an effect.
            Thanks!

              That is usually factory set to a certain standard.You could probably go on the website and call up the TP your using and find out that info.

                Would machine acceleration and/or move speed be a factor in this?
                Thanks!!

                  I looked at the book that came with my TP20s. All it mentions is medium, standard, and extended force. Color coded in order; black, grey, brown.

                    There are gram gages that will measure that. It will tell you the force required to trigger your ttp.

                        I have found some info in the Renishaw catalog. It says that a medium force TP20 has a trigger force of 0.08N XY & 0.75N in Z. It also mentions an "overtravel force"...does anyone know what that means? Thanks!!

                          James - thanks for the info, this may be what I'm looking for. Can this datasheet be downloaded from the Renishaw site?
                          Thank you!

                            I would imagine so. I have a copy given to me by the Renishaw guy (its' on a thick paper so I know I didn't download it). That's why I included all pertinent info.

                              Like James said 0.08N = 8.1577297g, 0.75N = 76.4787160g
                              I wonder what the acceptable ± tolerance is? My guess is the module probably goes bad for reasons other than the strain gage first but I have nothing to back that up. Modules are nice but I like the "tunability" of the old TP20s and the TP2s, at least for manual machines it is nice to be able to tune it. For DCC I suppose it is less relevant to have to adjust asside from changing modules.

                                Trigger Force???
                                by Hardrive
                                Morning gents,
                                I know about the tp20's and the different forces in the modules, but can I change the force in Pc-Dmis so it doesn't touch so hard....

                                by himmel_dustin
                                It seems to me like my probe takes to hard of a hit on whatever surface it is reading... what should normal max,low force be? or trigger force?
                                ...

                                I am measuring a flexible part that I can't support. I'd like to reduce the trigger force to get accurate result and to make sure the part doesn't move....

                                I need to write a CMM program for a cork part. The part is way to flexible to use normal settings so I need to change the touch pressure for this program...
