clearance for 3d milling

[brian]

I'm doing a 3d milling that is 2" thick in 2" stock.
Rough pass .5 endmill .2 offset
Finish pass .25 ball
I'm worried about the spindle hitting the edges of the remaining wood outside the cutting zone.
Do I remove some wood outside the intended cut area.
Or do I buy a longer .25 bit.
Let me know how you approach this.

create vectors outside the perimiter of your work and pre remove the material that will hit the collet
