Heart shaped box

Postby cusoak » Sun Feb 11, 2018 3:59 pm

I made a 1.5 'high heart shaped box with a heart shaped pocket off set by .25 from the out side 1.25 inches deep.
Then I used the same heart shape and made a lid. Using the same vector as I did for the pocket and the out side shape I cut a pocket there. Then another toolpath to cut the top out.
Well to my surprize the top did not fit into the pocket in the bottom.
So I am trying to figure out to set up to cut the inner shape smaller in the top to allow it to fit
Is there some way to do a inner cut allowance.
Or how do I make the top fit into the box.

My guess is that you used the "default" setting of climb mill. Cut conventional direction

Not sure how changing direction of the cutter that will make the area of the top that needs to be smaller any smaller when it is still following the same vector.
That is what I needs to happen.
I thought I saw a video some where that showed how to fit 2 parts together using some offset that all you need to do was input a value.

Because machines flex, especially hobby machines like the ShapeOKO.

When climb cutting, the tool is pushing away from the part, resulting in slightly larger parts.
Conventional cutting pulls the tool into the part, resulting in slightly smaller parts.
