Spherical groove

[Anonymous]

Hi. this is surely a dumb question but I am becoming crazy on this.

I need to design and machine a very simple groove meant to accomodate a spherical head screw.

The ideal  would be the ability to "sweep" the sphere along a specific path ( as it would be milled) .

This would me allow to control the width of the groove considering how much the sphere is deepen  in the solid

Maybe there is an easier way to do it but I was unable to find it.

Can someone help me?

Like this?

Revolve cut the semi circle, at one end, then extrude the vertical face to the other end of the centre line, then revolve cut the other end, 90 degrees.

You could make yourself a slot sketch to define the groove, then sweep the desired profile around in that slot to cut out the material.

Thank you both for the help. I managed to make the groove.

regarding the first solution I had to use a perpendicular sketch at the beginning for positioning the ball deep enough in the metal sheet. after that I extruded it and then used revolve on both sides .

The second technique is fat and easy but I had to use revolve anyway for make the end curved isn't it?

Thank you very much at both of you.

My method does not require you to Revolve the ends. If you make your profile exactly half (one side) of the slot width, AND if you choose the outside of the slot as the path, the Sweep will wrap around the ends and come back down the other side, removing all the material in one operation.

Look closely at the picture I provided. You will see that the Profile is half the width of the slot, and the outside of the slot was chosen as the path.

ok I understand , in this specific case if I should  do an elliptic   path .

thank you

I know this is long, but it might give you some good ideas.

I am a real beginner with fusion , I had to change a lot of software during last time, sketchup first then onshape now Fusion. Sketchup was the one I used most , so I have to make some brain washing for "thinking" in a fusion way 🙂

I have built a small CNC and the fact fusion have CAM capability is a big push for me to learn and stay with fusion 🙂

Thank you for the time you spent for helping me I learned a lot from your video
