I currently send out via either email, or if very large on CD, G-Code files for complex shapes, all I require is your preferred type of cutting strategy (Spindle speed, Surface speed, depth of cut, step over etc), Although I can provide this, type of controller Fanuc, Heidenheim, etc, and after some small test we should be ok.
I regularly send out files in the region of 100mb up to 60hrs machining time, and have some much larger, and of course very much smaller.
Pictured on the upper left is a finishing pass using a 0.5mm Ballnose Endmill for the moving half of an injection mould tool, of High end Model soldiers which stand 52mm tall (Note the grenade in one hand and the rifle in the other, next is the cutter path being simulated.
Below that is a 4th Axis path for a Spur Gear
Bottom left is a snippet of the G-code for the soldier, (Fanuc controller 17Hrs Machining time.)
