CNC Question!

Hi All!

Just a quick couple of CNC questions.

Am hoping to test out CNCing this join, would anyone know the best way to do it? I can’t work out whether the negative would be cut in panels or altogether. I know the piece that slots in would be CNCed in 2 parts but can’t work out the negative!

Second question, does anyone know of a place that would have a 500 mm x 500 mm CNC bed? I realise the makerspace is limited to the small bed, this join is part of a modular box I’m hoping to make but if I can’t find anywhere am happy to just test the join itself at the makerspace!

Thanks guys, hope someone can help!!

When we get the second arch up and running I believe we will have a 2400 x 1200 CNC :slight_smile:

Thanks so much!! I am looking forward to that being in use, sadly am needing this worked out fairly urgently :(( so might be a case of just using the small one

I think your options for the internal feature are

  1. Acquire a cutter to directly cut the profile.
  2. Laminate the sheets in two halves. This would require slow 3D contouring tool paths and won’t make as tight of a joint
  3. Cut on a table saw. This is the fastest option but would violate SLMS rules and would have to be done elsewhere
  4. Make a jig to cut with a router straight cutter at different angles.

It looks like you could use a dovetail router bit of which we have plenty, only if the shape didn’t have the curve at the bottom…

Petra is right, looks like a classic sliding dovetail

I think the round bottom is a special part of the x fix system. The engineered bow tie is actually two wedges.
