This is a short video of my CNC-converted Grizzly Mill-Drill (Sieg Super X3) being used as a lathe to cut a switch knob for a PDP-7 computer. A 3/8″ 6061-T6 aluminum bar about 3″ long is mounted in a collet in the mill, and is driven past standard lathe tools mounted to the mill table. The spindle is running in reverse direction due to the orientation of the tools. I created a G-Code program by hand to make the two different tapers and cut off the knob at the end. Depth of cut was .010 because heavier cuts caused the rod to deflect too much. Spindle speed is about 800 RPM; cuts were made at 3 inches/minute except for the final cutoff, which is about .3 IPM. UPDATE: I have received a good number of questions about the videography. I used an HD camcorder (Sony HDR-SR11) which captures in AVCHD format. youtube will not accept AVCHD video, so I used a program called Free HD Converter from Koyotesoft.com to convert it to MP4 at 1280×720 resolution; which I was able to upload directly to youtube. Not much work all told, and the results speak for themselves. Of course, good even lighting and using a tripod are key to getting good video.

Machining refers to the industrial process of cutting and fabricating metals and other materials into predetermined shapes and sizes. Machining process is controlled with the help of computer numeric control (CNC) software that guides the cutting equipment along the lines and arcs of a computer aided design (CAD) drawing.

A machining process may involve the use of different techniques depending on the number of parts being manufactured and the type of material. Machining techniques may include manual machining, which is used for cutting metal sheets in simple shapes such as circular, square, and rectangular. This process is however being replaced by automatic machining systems and processes that can cut any type of shape out of metal sheets needed for different purposes.

Chemical etching machining technique is mainly used for producing typical precision parts. The machining system offers a great flexibility for producing precision parts with unusual configuration as well as metals with tight tolerance within .0005′. Besides this, chemical etching machining is capable of producing small holes and bars that are not possible with other machining techniques. Another common process is Wire Electrical-Discharge Machining (EDM) in which the metal is separated from a conductive work piece by means of electrical erosion. During this process, the wire never touches the conductive work piece and leaves a path on the work piece, which is slightly larger than the wire.

Another technique known as the metal stamping machining phenomenon, which is also referred to as progressive die stamping or long run metal stamping, is extensively used in production of precision parts with thickness from .002′ to .135′. The technique is mainly used for processing typical low price parts that are formed into three dimensions.

Apart from these, some modern techniques are also in use such as abrasive water jet and laser machining that are more accurate and environment friendly as compared to conventional machining techniques.
