Hello.
If the finishing distance is 0.3mm and Madcam roughing a pocket... Why madcam also dont cuts the middle of the pocket?

There also stand Material in 0.6mm... 0.3 from both sides.

I hope you understand my english 😒

Because Roughing only go in complete Z-steps. If your roughing is set to 2 mm steps and the material left is 0.6, there will be no 0.3 mm pass. If there was 2.3 mm left there would be another pass, if there was 2.2... ...no.

Okay.

I understand. 🙂

But what's to the side? The stepover is 50% but in the middle of a square is region that the bit don't cut.
