VMC 4 axis contour help

[RICARDO_GOMES]

Hi folks,

I am a new member at the forum!

I,ve started working with mastercam a few months ago and i have never had any kind of formation at it, so, i am learning it by myself, with the reasonable doubts that are comming.

Well, see the atchment, please, it is a part i have to machine on a vertical milling  cnc center. The machine have XYZ plus A axis, A is a rotary axis. 

The part is a conical part with a recess at the outside. I have tryed a lot of diferent configurations but i could not have success wit any one. It absolutly needs the sides to be sharp edges, not round ones. How can i achive that? As you can see, i use a 5 axis flow to achive the recess, but i can not find a way to achive the sides to be sharped edges. What do you advise?

Thanks in advance.

Best regards!

Well, no one had a clue but i finally made it.

I have used a 3D contour but it needed to be changed at some points: the use of axis substitution, y axis. And this Y axis take me a lot of time to find out. Last, use a rotary diameter bigger than the part itself to achieve side by side perfect tool alignment. That is it.
