the tool is not milling till the bottom of the part do i need to change the cut parameters setting.or
do i need to use other method?
is parallel finishing is ideal for this type of part or use others or mixed need suggestion on this


Do you have a Z limitation set in the Mop? Looks like you might have programmed the tool to not cut below Z=0. To cover the entire part including vertical or near-vertical walls, the ball-end mill cutter needs to be allowed to go below the bottom of the part by the tool radius.

Hi thanks for reply.
U means the Z CONTAINMENT section?
