This is really, sorta, not a CMM question.... but then again, it is. And I have never been disappointed by the knowledge of this forum! ANYWAYS...
I have a drawing, its a sheet metal part, that in the notes says I can restrain to 10 lbs MAX.?? (to datums). How would anyone rate the poundage of a clamp holding down a part, on a CMM table? Kind of a grey area. When we have a machined parts its suppose to be measured in the 'free state' ?? Again... the part will move if you do not clamp them down. Any thoughts?? Its funny because an "engineer" will say.. "thats suppose to be in the free state" , only if their part isn't correct. And I tell them... .show me how YOUR supplier inspects this part without holding it down....nothing ever becomes of this.
Paul Sarrach we have the push pull ones. The gages are fixed to a base plate that slides on a track (T slots with a thumb screw) this allows us to set a prescribed amount of force either pushing or pulling and lock the base down as needed.
for the dive weights we have designated amounts we can use per inch / foot up to a max amount. kind of a PITA as we sometimes have to modify cmm programs to avoid the weights.
