How to cut along a singular path?

[machinemoney (Chris Hayes)]

I took a screenshot to better explain what I’m trying to do. I’ve seen others seem to be able to do it but I can’t figure it out. I have a wavy path that I need to cut out, it just needs to make the cut back and forth over this path. The red highlighted area should be deleted because if it cut there it would ruin the work piece.

Any tips on how to do it?

What you want to do is create a pocket that is only on the left side, then pocket that out.

I’ll assume you are using a 1/8" bit. First, Offset Vectors (to the outside) slightly more than the width of the bit (I’ll use .135"). Next, draw a shape that roughtly encloses what you want to cut:

Now do Boolean Intersection with that shape and the Offset Vector you created earlier:

Now take that shape and the Original, and do Boolean Subtraction, to get:

Now do a Pocket toolpath on that shape.

Here’s that file with the intermediate vectors kept:
