Lathe Tool Offsets

Hello,

The Mori SL-1 project is up and running. I have a question on the tool offsets. I am using version 4.32a.

In the tool offset screen the offset that is labeled Y I assume is just a typo and is actually the offset for the Z?

How do I make the X and Z offsets active through G code?

Thanks.

Hi Epiphany,

No that isn't a typo. There are X and Y tool offsets. The Z offset is called the "Length" to be consistent with a mill or router.

G43 turns Tool Length (and offset) compensation on. G49 turns it off. The H word specifies the Tool Slot or ID (Numbers less than 100 are slots, greater than 100 are Tool ID references). So for example:

G43 H1006

Thanks for the heads up. I have this working and taking cuts, works great. In regards to the G32, I have it working although it is not making the 45 deg pullout and leaves a groove at the end of the threads.

Here is a sample of the test code I am using.

G20 G40 G49 G90
M6 T5
G43 H5
M3 S500
G00 X1.0 Z.1
G32 Z-1.0 F.125
G00 X1.03
Z.1
X.99
G32 Z-1.0 F.125
G00 X1.03
Z.1

Thanks for the help.

Hi Epiphany,

I don't see where your code specifies a 45 degree pull out. You must code a second G32 to stay synchronized during the pull out. See this Post for an example of the code. Not it is also important to have the correct Trajectory planner settings. A Break angle of 45 degrees or less would cause a undesirable exact stop. And it would be good to round the corner for a smooth transition. Not also that the Feed rate on the 45 degree pull out should be increased by a factor of 1.414 to maintain the same thread pitch along the Z axis.

Tom,

I see now :o. After closer examination I understand how this works.

Thanks.
