Re: 60 Degree DIY Mid Hi
Max,
Way to dive in on this project, and work on executing!
In addition to controlling depth of cut, you'll need to make sure your feed rates are compatible with material. What sort of endmill are you using (upcut/downcut/compression)? How many flutes? What is your spindle speed, and have you checked feedrates for proper chipload?
Does your CAM package do things like ramp in and and out, or control toolpath speed around tight corners? If your spindle has the juice, it would be preferable to execute these cuts in a single pass, even it requires a ramp in, and/or modified toolpaths for corners.
Briefly looking at the Shopbot site, their workhorse machine would appear could either be a 2.5 axis, or perhaps true three axis. Either way, things like miters and fillets are either going to require special cutters, or are going to be secondary operations off machine. It would be my suggestion that you finish your miters and fillets after CNC using a table saw and router/router table with a roundover bit.
Since it appears the Shopbot uses a spoil board, it would be likely they have the tools to make spoil boards, and therefore plenty of tools to execute your secondary operations.
Drawing components for CNC, or most other manufacturing processes, is typically trivial to setting up and owning the manufacturing steps to replicate the drawing. See for example.
