  • Temp Compensation Settings Global 4.2mr1

    Im new to this equipment and others have come and gone since it was installed. Setting changed ect. What are the recommended settings on a Global?


    We have the optional material probe and its not used.

    The rest of the temp Comp system appears not to be enabled. I thought it was odd given the accuracy of features we are trying to verify.

    As a bare minimum I would think the controller & axis comp would be default.

    Am I going in the wrong direction?

    We have all the bells and whistles for the temp comp and never use it.

    It depends on what you are measuring and the environment you are in.

    We measure mostly heavy wall titanium.

    If we were measuring aluminum we would need to set it up and use it.

    I am not saying that because we are measuring heavy wall titanium that we will see no expansion/contraction, but in our case the value gained is minimal.

    A material with a greater coefficient of thermal expansion can REQUIRE temp compensation.

    We should probably be using it...we don't.
    Lately, it occurs to me
    What a long, strange trip it's been.

      I come from using systems where machine temp comp was not optional... it was on all the time and if failed the machine would error so my instinct would say it should be ON. (not referring to part comp)

      If the machine was calibrated with temp comp on, then it seems that it would have to be on when you used it.

        You should find settings in file "serv1.stp", I don't remember the exact directory. Use the compens by the controller for part and axes, it's better. The compensation works while you don't shut off the controller. I insert the comptemp function at the start of each programm (Comptemp/F9/recall default values/enter).

          I had worked on an Alpha with temp comp.
          It was my understanding the temp comp was required,
          the machine was calibrated with it on and it was needed
          not only to compensate for the part, but the machine as well.
          Without it turned on, the machine is effectively not calibrated.
          Of course, more than not the line I would add to the program
          to turn it on, would be deleted by the operator.

            Thank you. I will enable it in beginning of programs.

              +1 machine must be calibrated with temp comp on in order to use temp comp
