Pocketing cut direction

1

(“Pocketing” in the general sense: not the Kiri:Moto “surface clearing” sense.)

I’m carving some irregular holes directly through a board. Some holes are circles, some were hand drawn. They were all converted to SVG, and imported (via DXF) into OnShape.

Because I don’t want the plugs floating around and jamming the mill when they’re released, I’m planning on simply clearing the entire void. When I rough out these holes, it’s important that at least the bottom-most layer is cut from the middle of the opening outward, so that the last bit of plug is all sawdust by the time it’s done.

Is there a way to control cut order (out to in, or in to out)? My shapes all seem to alternate cut direction layer by layer – very efficient, but then the final cut direction depends on the number of passes. The longer irregular shapes don’t seem to alternate as reliably, so I don’t know that I can predict the final cut order.

Am I missing a way to control this?

(I tried switching to “conventional”, thinking it might have an effect. It didn’t, but then I realized that my holes are being milled with alternating climb and conventional milling, layer by layer. Is this just because I’m only using roughing?)

there is no current setting for this, but I can add one. the current roughing strategy is to make the smallest possible travel move that starts cutting again. when using the in/out out/in path planning this means we don’t have to [ lift z, travel, plunge Z ] nearly as often

I understand that completely. If there were another way to accomplish what I need, I’d happily use it, but I didn’t see one.

[ How do most people deal with the “loose plug” issue? Double-sided tape might do it, but I’ve had bad experiences with it letting go and ruining pieces in the past. :-/ ]

if you want to file a github issue / feature-request it will help me keep track of this
