Would anyone have an idea where to find some information about writing post-processor for CNC machines?
Thanks

i.e help or something
you can modify the post processor of any software according to the codes your machine understands and this is always not a very difficult stuff
RE: Writing post-processor for CNC lathe
We have found that for simple 3 axis machining, it is sufficient to modify an existing post to suit our needs. generic posts are usually supplied with CAM software.
However, for more complex and specialised machining, (eg 5 axis maching of complex surfaces), we have found that writing our own posts using Visual Basic gives us the most control over the tool. Once you have a CL (cutter location) or APT file you can write your own post, which works with your machines in the way you want it to.

airuno is askink for absolutely different story ,
he is a student in the first degree in the university of agriculture and wants to learn the early beginings of G codes and post processors I doubt that he knows what a milling machine is .
but anyway thanks a lot

Thank you

Here is how mastercam works:
An NCI file is generated by the software which contains tool, cycle and cutter location information. The file is set out as follows:
CYCLE
PARAMETERS
For example, a rapid move would be defined by the following 2 lines:
0
10.5 3.8 1 0
In this example, the first line contains a zero which defines that the following parameters are for a rapid move. The second line contains the rapid move parameters: x position, z position, cutter comp, move angle.
The post processor merely needs to have a databse of all the cycle numbers and what parameters each one requires. Converting this into G-code is then straightforward.
