On machine probing
On machine probing
(OP)
Hi,
I have a doubt regarding on-machine probing, I mean using touch trigger probes on CNC machines. Considering that machine tools themselves are not that accurate and repeatable, how can we rely on results given by a probe mounted on the machine tool spindle? Isn't a CMM probe more accurate?
Thank you.

I am sure this might be properly addressed by probe manufacturers, but I am not clear with this.

At least that is the way I have used them.

Secondly, in addition to initial preset people are using this to check final part dimensions after machining on the machine itself. It's here I've doubt that how well these values match with that of CMM measured values.
