Beginner's Guide to CNC Milling. CNC stands for computer numerical controlled machining, and milling is a process that is similar to both drilling and cutting. However, in the case of CNC milling, tools move on multiple axes, with the work piece moved in different directions. On a traditional machine, the cutting or drilling occurs …

Dr. Garner tasked us with converting one PM-727V to CNC and leaving the other as manual. This was for a number of reasons, the first being that a CNC machine can make certain cuts that are impossible using a manual machine. Secondly, the CNC machine takes the manual mill from its 0.001" table graduation accuracy using lead screws, to …

A human would turn the hand wheels in order to make parts. A CNC machine will use motors to accomplish the same thing. Motors come in two basic varieties, stepper motors and servo motors. Steppers are a special type of multiple pole motor. Each pulse of current turns the shaft some small angle, typically 1.8 degrees.

The machine code to make your part is generated in several steps. 1. Your Rhino designs (2D or 3D) are used by some CAM software (which can run inside Rhino or as an external application) to generate toolpaths. This step needs your input to some degree. (This depends on what CAM software you're using and the complexity of the part.)
