That, of course, is NOT true on 5-axis machines with different construction. Certainly, Chris Radek's 5-axis desktop mill is an example. Proper kinematics solves this, but you have to be in world mode for it to work. I believe Chris has a video on Youtube with the machine drilling a hole at a compound angle. I THINK it can do this in manual, as well.
