Here's my machine!
Got the frame almost finished. Gonna use 20 mm Hiwin linear slides.
Now, Gotta make the final decisions on the motion control. Thinking about 3/4" x 5 Acme leadscrews and 0 lash Supernuts.
For motors and drivers I am thinking about 600 in. oz. servos (500 cpr) and Gecko 340s. This should give me plenty of resolution at the single pulse per step rate and faster cutting speeds in the multistep mode (.00025" vs .0025"). Obviously a lot of other factors come into play regarding accuracy. But the drivers and motors area key factor, all other things being kept under a reasonable amont of control.
My goal is to be able to cut at high speeds at a modest resolution and high resolution at low speeds.
NC application will be Mach 2 and
CAM app will be Visualmill to take laser scanned inputs and create 3D surface cutting routines.
Does this make sense?.... Comments... Suggestions???? |
