Clean hole cutting tips

[cademaer]

My machine is cutting clean and accurate holes, very little to complain about!

BUT I'm still getting little chunks cut out beyond the circle area where the torch turns after the beginning lead-in. I saw a video where the torchmate machine does a swoop inwards and overlaps with another inwards swoop to complete the circle cut (horrible description, I know).
What is this called and how can I get my machine to do this to make my holes look better?

Thanks!

In the CAD you can change the type of lead in along with add an overlap to help reduce the pierce area.

So you have your part created and selected. Go to MACHINE/CREATE TOOL PATH/MALE

add your feedrate under BASIC CUT TAB then go to the LEAD-IN/OUT



So change to ARC and then you can add just a little overlap. Usually 30%-50% of the thickness of material will help smooth it out.
