I've been writing my own code for the last several months and have MS Excel setup parametrically. I have the input data (usually just part type, ID code and part length and width) in a few fields on one sheet, calculations on another then the sheet with the actual code on another. That way I can just type in the part info in a few cells then the entire 100 - 600 line program gets updated and ready to copy to the text editor and feed my machine. I'm saying this because a modeling program is out of the question since I can only model one size at a time.
I intend to start making doors using "round-end tenons" which are just like regular tenons but with ends the same radius as my tool that cut the mortise slot. I'll do this with my 90 deg aggregate head with, for example a 3/8" mill tool. I just watched a video on cutting arcs in the X-Y plane and it seems simple enough but as you can imagine I need to do this in the Z axis. Can anyone describe how this is done?
Cheers!
