Setting lathe tools with a touch probe V5.08

[PhilipTrueman]

I have been using my touch probe to set up my lathe which has a turret and is rear mounted.
When setting up the lathe tools using the touch probe I first set up tool number 1 and use the auto touch off to set the Z ref and the X ref in the tool offset page.

Lathe tools
When setting up tools that face towards the operator the X ref diameter figure should be a positive value ie 10.00mm for the probe diameter.
And the approach for the tool should be in a negative direction.
Boring bars
When setting up boring bars that face away from the operator the X ref diameter figure should be a negative value ie -10.00mm for the probe diameter.
And the approach for the tool should be in a positive direction.
Drills
When setting up drills the X ref diameter figure should be a negative value ie -10.00mm for the probe diameter + the diameter of the drill. ie a 12mm diameter drill would be -22.5mm
And the approach for the tool should be in a positive direction.
I hope this helps for some people using a touch probe for setting up lathe tools.
I had a problem with the parting tool and the threading tool setting the X offset The threading tool was 10mm out and the parting tool was 20mm out from the figure that it should have been.
Is there something wrong in the programming with the way Centroid sets up these offsets for threading tools and parting tools?
I would like my boring bars cutting edge to face the same way as my turning tools but this is not possible because of the way the cuts are made on the ID of a bore.
I have attached a report.

When you say "tools that point forward", presumably you mean "away from the operator". And when you say boring bar "face away from the front", you mean the insert is pointing toward the operator.

As you know, I had problems with lathe tool offsets. I forget the specifics although I recall I couldn't figure out a consistent explanation for the error. Either way, until the release notes suggest Centroid have addressed it, I am manually setting offsets. Not ideal but what else can I do?

Yes it is still not right. Has it ever been correct from the first version of Centroid 12?
There must be variables for the threading and parting tool as these don't set correctly. I tried it more than once and it is consistant in getting it wrong.

I am using both front and back for gang tooling, and it works perfectly with the probe.

For drills I use a centricator in X and Y and the probe for Z

In 4.62 ID tools were not ok with the probe, that was the way I came to beta testing.

All later versions are ok.

I will have to use a coaxial indicator to centre the drills to be very precise.

It is called a coaxial indicator in English.

ok, my English is featuring some potential for improvement

No worries

For drills I use my harbor freight center punches and a dead center in the chuck and eye it up........YIKES
