I am using CAMBAM to illustrate the CAD process. CAMBAM includes a few basic CAD functions and primitives that enable you to design an object. I say basic CAD functions, but CAMBAM is extremely versatile and there really is no limit to the complexity for the object. In the next tutorial, I will exhibit some of the great features of this program and design something more complex.
Once I create the design, I then use the machining functions. In this tutorial, I limit the machining functions to drilling and profiling. Three holes will be made using the spiraling drill technique, where the bit is smaller than the hole. I will also show how to make similar holes with profiling; however, you will see that the drilling method is cleaner and makes a perfect circle. In addition, the profiling will be used to cut out the final object.
