How can we generate program on CAD CAM?

Hello Sharjeel, your question is so general and broad.

In principle, CAD is the geometrical representation of something (a design/part/component or even a sketch) in a computer. This also applies to2D. Some people expand this term to include the process of design using a computer claiming that CAD stands for Computer Assisted Design rather than Drafting. The representation itself can be used in many many and many different applications, including manufacturing & machining, but it’s never restricted to that.. No way!

In machining, you need to have CAM in order to do what you're up to of doing, out of the CAD data that you have in your hand. This process include having the CAD data fed into your CAM system then applying the needed machining strategies (or steps) in order to get what you want from your machine tool, that will have a workpiece to be machined, cut, shaped…etc

There are many CAD tools in the market, as well as CAM systems. Each one has a different flavor depending of whta you want to do.

Sorry, I can't elaborate more unless you're getting more specific.
