I recently acquired a Brown & Sharpe Reflex CMM. I never had or used a CMM before so everything is new to me! After getting it set up, I checked the precision of the x, y, and z axes using gauge blocks. I ran the machine in "height gauge" mode. I performed the measurement with blocks of different sizes. What I observed was the Z axis results always had approximately 0.078in added to the values. The other axes did not exhibit this.
I ran the probe set up procedure several times and got the same result. The machine also came with a second
(Renishaw TP1) probe and I got the same result with the different probe. I posted a table of the measurements in this thread to illustrate what is happening.
Since this mode of measurement only takes two points and subtracts them, how is it coming up with this additional value?
Anybody have any idea what is causing this and what I could try to correct it?
Thanks,
Alan
