need smaller radius in pockets on a surface

[left coast lefty]

I have a bunch of surface pockets on the slope of a dome shaped part. Now the customer wants smaller radii in the corners, but no new model of course. I'm having trouble figuring out how to do this without re-drawing the part.

 

I used surface finish scallop, start point in the middle. Works fine. I tried to chase it with a 3D contour, but I can't change the fillets in 3D.

 

What am I doing wrong?

 

Thanks in advance.

Solid? Make mating solids with smaller rads, then boolean remove. At least you would not have to redraw the whole part.

Not a solid. I always bring in step files as surfaces with lines, arcs, and splines.

 

I haven't even tried to work with solids yet, to be honest. Not sure when it would be beneficial.

 

Thanks a lot MCM.

Right now.

can you extend the walls, remove the fillets, then re-create fillets to revision? then trim surfs

[Justin Beebe at Folsom Tool]

You can try this. I did it with a simple model and it worked but I don't know what your dealing with.

 

1. Create a solid from your surfaces

2. Use solids find features to bring up history on the fillets

3. Change the fillet size using the solids fillet parameters.

I always import step files as solids so I can modify if necessary then make surfaces from solids to machine to. Modifying the solid would be 10x easier than modifying trimmed surface models at least for me anyway.

Thanks to all!

This should get me headed in the right direction.

Toolpath /Surface / Finish / Project.

 

Make a toolpath that cuts the sufaces walls with contour in 2d and project that onto the surfaces using the tool dia. that will give the proper inside corner rad.

 

Bag the model, get this running and move onto the next part.

Thanks Verndog.

 

We have a winner! This is what I was looking for. I will try manipulating solids later, need to make chips today.

 

Thanks to all, really appreciate your help.
