Tool Offsets and Z position display in hand jog

[aadrew10]

Hello,

I have not been able to figure out how to make any of the 4 position readouts give the position of the tip of a tool in the Z direction. I would ideally like to be able to change through tools, and then be able to scroll down to Z0 with each tool, and have that position be at the zero point of my work piece. While a program is running, the readout shows the z height of the tip of the tool. I would like to get it to do this in hand jog mode. I hope this makes sense. Any info is much appreciated.

Thanks,

- Andrew

Hit the post bit key a few times it will give youa few different options axis position options

As far as I know, the only way you can do that is to program a move to a known height in MDI, then zero the operator position screen, then make incremental moves from there in handle jog mode. For instance, if you have G54 Z set to the top of your part:

G0 G80 G90 G54;
G43 H1;
Z0.

From there, you zero your readout and move around.

Yep.
I keep this in MDI:

G90 G00 G54 G43 Z2. H1;
M30;

Then I change the H callout to the tool in the spindle. Once it gets to the position, I set the Z to 2.0 on the operator position page. You can add X0. Y0. to it and set those axis as well.

Thanks for the tips guys.
