Heidenhain Programming Help !

[ShiZniT]

I am working on a Horizontal CNC Boring Mill (5 axis) machine with an iTNC530 Heidenhain Panel and i have a preety hard program to do and i don't know how to make it.
I attached a photo so you can see what i am talking about ... i have to make a half circle on Z Y axis and i dont know how to do that ... i tried with the C an CC function but no luck ... I am tring to do this with a 40 mm diameter mill
Please help me guys

Don't know about any more advanced 5-axis options, but on a 3-axis the first thing I would do is a Tool Call with X as the spindle axis.

Would probably set up a spherical cutter using the centre of the sphere as the reference point for my tool length/radius and program it using CC and C movements as you thought (arc radius size = part radius + cutter radius), incrementing in X.
