Parametric Japanese Timber Joinery for post and beam construction

My goal had been to design my structure as lines (or lines and arcs) and then take each joint and specify it’s parameters.

Do you mean “wire-framing” the joint by making simple line shapes (e.g. T or Y shape) and then extrapolating from that the joint geometry? Or something else?

Somewhere out there someone has done this for the extremely elaborate and ornate Japanese joinery but I can’t find that link now.

Also think about how you will fixture your robot and the limitations of routering mortice and tenons… for example, a 10mm cutter is going to leave 5mm rads in the mortice corners so perhaps you want rounded tenons to match! Perhaps you can get mortice drills for robots though?

I don’t know about mortice drills for robots, but you can get mini-chain saws (Bosch NanoBlade) that could do plunge cuts, but they are kinda annoying to use. Rounded corners are all good. Some papers out there on people doing similar things…
