No, the thing is that i have a 3 axis milling drilling machine that i have converted, but in april there is a new syil X6 big table with 4 axis that is arriving to my workshop here, in Argentina. In my workshop i make engine competition parts, and i want to make an inner shape, so that why i need the 4th axis, i dominate the solid cam with 3axis, but i never can do anything with the 4th. So i try with mastercam for solid works, it's great! but i dont dominate like the solidcam. I try for making one camshaft lobe, just for trying, and then i have tried something like that of the inner shape, but it's strange, because every single code the feedrate change, ok nevermind.
What i know about the 4 axis in the solid cam is that yo have to pick the rotary axis (x, y, z) and then you start with the option of the 4th axis. Did you try with milling turning option? because it make the 4th axis option available. But the post procesor didn't work, and the fanuc option is not available. May be with a post pro that recognize the milling turning option we can use the 4 axis.
