What value do you have in D08 offset ?
& Are you programming to "Comp in Control" ?

It cannot be larger than any inside radius, as it cannot follow the shape
5.999 may work, where 6.0 may not.

[Niketan1121]

D08 is set to 12, and yes, the program is set to "Comp in Control."
I have attached some compensation selection option window screenshots for reference.

Strange that you input a diameter size for a radial offset ... but if that is what your machine set up for, so be it...

My CAD plotting of your XY points gave a radius that was 0.0005mm smaller than your tool "radius".

Try setting the additional check in "look ahead" to check for any "internal corner radius <= tool radius"...


Query... have you tried using the "toolpath centre with comp" ?
-- Where a comp value of zero makes the path correct for a true sized tool
-- A +ive offset makes the tool pass further away from your part,.
-- and a -ive value makes the pass closer to the part.
This method cuts down on a lot of scrap parts as you only need to check that radial offsets are 0.000

I previously used a 12mm cutter, but now I am using a 10mm cutter, and it works.
