Hello everyone!

I hope someone know how and want to help me with my problem. I hope this doesnt seem too simple for you, It s just that i am a little bit uncertain.

I have writed G code myself and I wondered if its correct. I just want to make a thread with a mill using cylindrical interpolation in CNC lathe with driven tools. The mill is quite a small so I ll remove small amount of material just 0.1 mm. So i have to make several cuttings. the depth of threats is 1mm so its 10 cuts. When I program several cuts i quess I need to change cylinder radius notation. Here is an example Workpice radius=7.5mm and the depth of thread=1mm

and so on and so forth..

I dont have a postprocessor to do this. Can you tell me if this is correct???

Ill give any further information if needed..

Thank you very much!!
