What software would you recommend for being the most user friendly for single through 4- axis milling? The software I am currently using (geopath) is fine for drilling,tapping,& milling on flat surfaces,even using the 4th axis for rotation between cuts, but when it comes to cutting multiple splines, slots or spirals on the outer diameter of cylenders needing 4 axis movement at one time it becomes somewhat cumbersome. Any and all suggestions appreciated.This will be something I think all shops would be interested in seeing the replies!
