DFM Course 8 Part 1: Machining (CNC)

Course 8 will cover Machining and Stamping. First, we’ll cover the overview of the typical parts you might find. Then we’ll talk about the pros and cons for machining. After, we’ll look at how the process works along with some of the design guidelines. Lately, we’ll cover some of the common materials that you might use.

Onto Machining, or as we refer to it: CNC (Computer Numeric Control); in that the computer is actually driving the cutting tool. The other process is just a manual process of a numerical bridgeport, which is great for prototyping, but does not really apply for high volume. Some examples of machined parts are precision gears, if you need the extra strength of a metal gear, different fittings connecting two parts, or drive components to transfer power.

The full course lecture and accompanying slides are below:

    Thank you for sharing your knowledge. I have seen most of the Dragon videos on YouTube.

    I’ve always thought that CNC machining was a fascinating field. I’m not the most mechanically inclined person in the world, but I would be very interested in viewing this course lecture. I’ll have to check it out.

    It is good to know that cnc is still alive and well today. There have been predictions that 3D printing would entirely replace cnc at some point in the next decade, The truth of the matter is, cnc is still the way to go in terms of a lot of things, like building cars, heavy machinery, and materials with moving parts in general. Cnc is not going anywhere, it is still preferred over 3D printing since you still exercise a bit of control over the process.
