So, we just got a new Haas lathe. We are used to the older Fanuc lathes, so its not that big of a difference. We came across one tho.

In the Fanuc, in MDI if we type:

T1111 G00 X8.9 Z0.

The relative position would be correct to the tool offset

Is there a way to do this in the Haas? If the above is typed, all positions are equal to machine home, and aren't giving the numbers that we want. Now I can do a X8.9 origin, and then the Operator Position will be correct, but is there a way to do this without having to set the position manually?

Sorry if its hard to follow, I know the Haas mills front to back, but not so much on the lathe.

Thanks

Relative will be relative to the currently enabled work offset.

OK, so.. how would I go about making that show me what I want then. I know that the machinist doesn't use G54-59 at all for X axis, so those are always set at 0. Is the only way of doing this by setting the operator X position to current X position.

Bit more info, this is just to manually bore jaws out.

Maybe I am misunderstanding the issue. Write a program for boring lathe jaws.

When I bore jaws I measure the tool then use ABS X for my diameter and if I need to hold a Z depth just touch the tool off the face of the jaws and origin Z in relative I do use a program some times but for a quick skim cut I dont.

[txcncman]

I am still not understanding your "relative" problem. Have you read the complete manual?

Try this:

Set G54 Work Coordinates to X0.000 and Z0.000 -

Set you boring tool for X and Z to the chuck jaws -

Go to MDI -

Clear any previous commands -

Type G00 X0. Z0. and press Enter -

Press the Cycle Start button -

Report back here what happens.

In order to HAND / JOG in the display position of the tool in the workpiece coordinate system, perform the following steps:
"MDI"
G54
T1111
G0X8.Z2.
M30
"CYCLE START"
"POSIT"
"PAGE DOWN"(Repeatedly until the information appeared "POS OPER")
X8. "ORIGIN" Z2. "ORIGIN"
HAND / JOG
