Returning to Hole Centre in Clean Circle

Hi Guys,

We have XR5 3D Mill Expert and have it posting to our Haas mills. The post works great for most things but this isn't something we do much, but it would be great to know it will work when we do need to produce this sort of feature.

I have used clean circle with a grooving tool, to put an undercut into a bore. The problem I am getting is that the tool doesn't return to dead centre of the bore before retracting the tool, this causes the grooving tool to machine some of the main bore out.

The hole is X0, Y0, so if I manually programmed it, I would just send the tool back to the X/Y zero before retracting in Z.

Is there any way to get the clean circle cycle to do the same?

It's an 18mm dia tool going into a 18.4mm dia bore and grooving out to 20.4mm dia

Thanks in advance for any help

No way in clean circle, Use mill profile.
Line in 1.2mm, leadin angle 90
Line out 1.2mm, leadout angle 90

File in inches.

John

Thanks John.

That works a treat. Not as simple as it could be, but hey ho.

use a g13 instead. will start and stop @xy0

How do you get OneCNC to use G13?

I am able to do that manually no problem, but I don't want to write half a program with OneCNC and then have to go and finish it manually.

i have not figured it out either. i just do a drill comand there and edit program. ive yet to see any cam system do a g13...
and adding a g13 is only 3 lines, so its not that bad

Guys,

Setting up your post to output a G13/G14 operation is rather simple.

In fact there are post on the OneCNC forum already set up to do this. Haas for example. But others are easy to do too..

Pop over and have a look..

Cheers

Cheers wms. I got the job done as John had suggested above but will look into editing the post going forward.
