Mastercam won't recognize curved pocket.

You can do the followings:

Option 1.

You just need to make a boundary around the pocket (use create curve all edges first to make the wireframe and the project the curves needed using project to the top plane z above the solid). In the toolpath pick the entire solid and then select as containment the projected boundary.

 

 

Option 2.

Use the general selection and click on Activate solid selection icon and then enable only the Select face icon.

Make sure that you select all necesary faces include the side walls.

+1 to Mariana... if you are using Surface Rough Pocket and just select the bottom curved surface by itself, you're not really selecting a full pocket... you're just selecting the floor of the pocket and Mcam wouldn't know anything about the walls (i.e how high they were). So you either you select the wall faces too, or create/use a tool containment boudary as decribed above (which does away with the need to select the walls on a relatively simple job like this).

 

Seperately, when you selected the top face and the tool went down into the three holes, the Pocket operation basically dropped the tool into them, creating its own boundraries on the fly. But as you found that might have not been ideal with the 1/4" end mill. Plus if you hadn't physically selected the curved surface at the same time, the result would have been a three flat-bottomed pockets

(Also if that top surface happened to have no holes in it at all, you would have got the same "no cut found" message as you did with the curved surface since again Mastercam wouldn't find any pocket shaped areas to cut out.)

 

It's worth knowing that if your curved surface was round in section (like a dish) rather than having parallel sides, Rough Pocket probably would have been fine. Once the toolpath got below the top of the dish shape it would see a "wall" all around the tool and decide it was indeed inside a pocket

 

Hope that all makes sense!
