Hi Kiri,

You're plasma cutting, is that right? kerf is based on your plasma torch, amp, material and thickness cut.

The fillet that you are referring to for filleted rectangles, different sizes fillets should not have an effect on overall length and width of the part.

It is not normal for parts to come out different length and width, if they only differ in corner fillet radius. You can of course confirm the NC CODE is correct.

Use FastPLOT and measure. If the NC CODE checks out, the rest is in servicing troubleshooting your cutting machine.

on re-reading my earlier comment it was poorly worded, i've updated it to not be confusing with the word 'size' and what it is referring to. Pardon me.

Hi

Jackson,

The Size refers the fillet radius dimension in the part.

Hi Kiri

kerf is based on your plasma torch, amp, material and thickness cut, rather than sizes of the fillets.

hopefully that clears it up!
