Gentlemen, Tool length offsetting is BIG subject. It is difficult to get people to agree on what it is and where it should be measured from. You must determine how you are going to do it in your shop and then be consistent with it. I have two machines that need the tool lengths set to the p

I guess I don't really see the issue here with tool length and diameter probing. Years ago now I wrote a little tickle script that allowed me to turn the probe switch over, pressed it with the tool and from the known height of that switch, wrote those values to the tool table and then reread the

Hi Chris, After thinking about it a bit. Are you proposing a tool referenced against the zero tool after every (manual) tool change? That would take time but would work for non-tool holder machines i.e. collet on the spindle as well as those of us with tool holders. Might make a really nice o

Hi Chris, You are quite correct in assuming I have a series of tool holders; however I do a lot of one-off stuff in which the tooling outruns the number of tool holders I have. With the right probe and program we ought to be able to gage both length and diameter in a manner analogous to the l

Hi Chris, others. Really tool length is just part of the problem. A tool number is associated with both a tool length and a tool diameter which may or may not be nominal. So far I just grit my teeth and work thru the process. I have considered (briefly) a procedure to normalize the measured

Hi all, In reading about the probe function it looks to do something close to what I would like to do with a touch plate. This touch plate is put on top of the material and Z is lowered until the tool touches the plate, which completes the circuit and turns on an input. When this occurs, I would
