Slant face machining in HMC

[Sunder]

I am doing programming in Mastercam X4 for a slant faced part which is going to be cut in a Makino HMC with a indexing tombstone. The part is loaded vertically on the tombstone and the slant face goes to the top. Instead of machining the slant face in a different setting, if I rotate the tombstone the slant face will be compensated and I can machine the face as a vertical wall...

I have calculated the angle to be rotated and created a WCS for that angle. After creating the toolpath with the new WCS, the solid verification in Mastercam cuts the part exactly as required. But when I do NC code verification with in Vericut software there is .025" stock left on the face. I am not able to understand why this happens...I have checked the offsets, tool dia, stock to leave, measured the toolpath, and so on, but still the problem persists.

 

If someone has already done these types of jobs, please suggest me the way to identify the angle of rotation and how to create the curve on the face...

 

Thanks...
