CAM in Polar format

I need to convert a simple 2D .dxf CAD drawing of a tool path to a
machine code in a Polar format, of the Vector distance and relative
angular Direction. I can manually write the code or manually extrapolate
the information from the verification functions in Bobcad, but i'm
looking to generate a post processed code automatically.

Any help would be greatly appreciated.

Thanks in advance,

Jay Hayes
