A fellow shopbotter has asked for my help in creating a 2-part solid box to house a sphere shaped puzzle. He wants the box split in the middle with the lid held in place by magnets. The sphere is 2.25" in diameter.
I need assistance in modeling the toolpaths in Aspire. I'm assuming it would be as simple as drawing a 2.25" diameter circle and use "Create shape from vector outlines" under the modeling tab? If so, what would the shape profile angle be? I'm also assuming that the depth of the recess would be half of the diameter of the sphere since the recess would have to be machined into both the bottom of the box as well as the lid.
Is there a easier method using a large ball nose cutter and a 2D toolpath?
Thanks for any assistance offered.
