Where this radius sits

The DNMG 0702 group in this directory has 3 entries, from 0.1 to 0.4 mm radius. This is the largest listed radius in that group.

Confirm the part contour and tool compensation for 0.4 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
