    Depending on how tight of helix is on you part you are probably going to need to tilt the head. I think you will need a 5 axis tool path for this job. I am sure you know that you need to create a CYS based on how you are fixturing the part. Then you will need to create another CYS that will allow your spindle or table to reposition the part perpendicular to the spindle. When you create you 5 axis toolpath it should do the remaining positioning for you witch should be minor. A 5 axis surface tool path will probably work good, a 5 axis trajectory will work as well but you need to know more about you setup. At any rate I do not know what your machine setup looks like or how you are fixturing the part. But your part needs to be rotating, head needs to be tilting as it moves thru the helix and traversing in the axis you have it fixtured in. You will not be able to machine this part using 4 axis.

    Are you just indexing with a rotary or do you have a full 4 axis cut?
