Best approach for CNC cabinetry project

evanbooth — Sun, 23 Feb 2025 16:09:51 GMT

Hey! I need to cut and carve a few cabinet doors to match the ones I already have (which were built traditionally).

Since these will be carved from 3/4" MDF with a CNC router, my original approach for this involved creating a profile for the bits that should be removed, and extending it around a path with a sweep. The issue, as shown in the attached pics, is that the cut actions are undone where the corners meet.

Given the user parameters shown, what would be the smartest way to approach this problem that would allow me to update the profile sketch to change the design of the cabinet door?

Thanks!!

@evanbooth

You have an offset between the cutting profile and the sweep path.

They should be coincident.

Also, the Handle on this end of the spline show have a Horizontal or Tangent to Horizontal Constraint.

Personally, I would use tangent arcs rather than spline as spline is art - not reproducible without a lot of work.

@TheCADWhisperer These are issues in the model, to be sure, but will addressing them fix my central problem?

How will you manufacture? Simply a route into a single MDF Panel? 3 Axis Machine? CAM will be tedious but you say it's just a few?

You can create stiles and rails then combine

Yeah, I'll just get as close as possible with my tapered ball mill on my 3-axis router.

@Warmingup1953 I really appreciate you putting this solution together-- I think it'll work perfectly!

@evanbooth

If it is a single piece rather than 4 pieces - there will be radii in the corners when manufactured in the real world.

Hi! This is a Sweep path issue. The path of choice here is the outer path, which can lead to collision. You need to create the inner path and the desirable result will be obtained.

Many thanks!
