Re: [CAD_CAM_EDM_DRO] Re: 4 Axis Cam Software

Hi Jon and all   
     That is why I ask the question!  For what he is making is he really going to be moving all four axis at the same time.  To move all four axis at the same time involves very complex trig. and calculus because of the different (feed) rates of change for each axis.
