  • Need a better understanding of T-Values

    Could someone please explain what a T-Value really is. I have never work with sheet metal axis before.

    I think it is what i want but not sure.

    Hello,
    The easiest way to describe it, from what I understand,,,it is kind of like true position, in relation to the vector and the compilation of x, y, z. Mainly used in sheet metal or stamping, but that depends on the customers requirements and surface points.

      I've never used sheetmetal either and what you just said, came in one ear, flew out the other
      I used to be high on life but I built up a tolerance.

        In relation to the vector??? i mean how does pcdmis calculate vector deviation and how is that used in conjuction with x,y,z deviation. Also if its something like TP where is the math....cant be anything alike.....

          The math calculation is something I have never bothered with or questioned. But now that it has come to light, I will have to find the equation (sp?). We may have to wait till the main gurus get back to work. I will search for it later after work, since the internet is limited here. May have the answer by monday,,,sorry

                    T value is surface deviation... a plus value is extra material, a minus value it missing material... the calculation is x dev squared, plus y dev squared, plus z dev squared and the square root of that answer... hope that helps... if you need more assistance email me.
