I'm currently working on a summative project for my grade 12 manufacturing Engineering Technology class, and it's going to be a "twisted block" (imagine taking a rectangular prism and "twisting it" one quarter turn). I am designing it on AutoCAD LT 2000i, and cutting it on a 3-axis Haas Mini-Mill.
I have most of the drafting done, but I've hit a roadblock: Since I'm using a 2-d drafting program to plot this, I need to figure out a few things. I dont have the luxury of tangency or loft functions, so in order to cut the 3-d "flutes", i need to know how to program arcs in the z-axis (universal G-Code). Also, was wondering if it is possible for the haas to cut both an arc in the x-y plane AND the z-axis at the same time.
If ANYONE can help me with this I would be very grateful. Just drop me an example-line of code (e.g. "z-0.200; g03 z-0.350 r.315" etc. etc...)
