Contour finishing -Toolpath 3D - Mastercam for beginners

[@aspeaerospaceprecisionenging]

very powerful toolpath not only for simple shapes but can finish complex part including flats . 1 of my fav 3d ops

[@majmunlud5934]

Just one question why did the toolpath go inside the model?
Because it's happens to me and I don't no way?

[@aspeaerospaceprecisionenging]

@@majmunlud5934 this happens because it is a 3d contour toolpath and if you select the face like in this case the only fillet going around the part (big rad face) you have 2 contours internal and external, Mastercam will finish contour from outside and inside :) 3:45 on this video
you have to select also horizontal faces (the top face in our case here)
90% of the times I select the whole 3d model :)
It is shown on this video (on Mastercam CNC)

@@majmunlud5934 Hello,
you can use containment boundary to limit machining area + check surfaces for faces you want to keep your cutter away from - (faces you want to avoid)
