With a Lathe, the spindle rotation direction for right handed tools is CCW. However, when setting up tools in Fusion 360 CAM, in order to have the tool use G03 (start spindle CCW) you must select spindle rotation CW. I see where that might be confusing because from the tool rotation standpoint, it is CW. However, in a 2-axis lathe the tools don't spin, the part in the spindle does, and again, for a right handed tool, the direction the spindle spins is CCW.
