Files for 3D CNC routing of plywood and MDF

I have designed several projects. I need output code to be sent to a local woodworking company's CNC machine. The first projects are panels for small boxes. After that will be designs for frames, chairs, and other household items. The parts will vary from 1/4" to 3/4" (6MM to 19MM) in thickness.

I will provide drawings and images after you reply.
