Dear Forum,

I am slowing stepping through to my first CNC attempt. I am using camworks and solid works 2013 and have an issue / lack of understanding of machinable faces, operation plan for camworks.

the part i have is very simple and for the most part the toll path works for me, however i add a fillet (larger radius)and re-run find machinable faces and camworks excludes the areas.

being a newbie, I assume camworks would instruct the mill to cut the fillet (3ax)? So my questions are:

am i doing something wrong?
is there a specific tool I need?
all of the above
other?

no sure where to start?
