If you wanna do Machining a model with the CNC machine than use the software Power mill (By delcam).
Just simply save your model as STEP/IGES and import it to the power mill, Make your tool spec and generate the program for a specific CNC m/c.
Just go through my power mill tutorials..!!
Answered with a tutorial: https://grabcad.com/tutorials/hi-how-can-convert-a-3d-max-file-to-cnc-machine
Is there another way
export like ACIS sat an then in alphacam inportte file
It's also depend on your model complexity-ness ,
I mean that if you have simple model in which you are able to write the co-ordinate for each place than able to write programs by manual.
If you tell me more about your 3dMax model than i will surely help you completely.
To do machining with various CNC machine is only the way to generate its G & M code, which tell the tools to move in a particular curves and direction.
Final thing is, you have to generate the G & M code's to do machining your model.
Either the software is Power mill or any similar.!!
