SME: Basic Manufacturing Processes

SME (the Society of Manufacturing Engineers) has a great playlist of Youtube videos that outlines many basic manufacturing processes, and they are all right here for you. Most of the videos are from two to five minutes in length, and get the main points of those processes across to students in an easy to understand format. There are 44 videos in all. Thanks SME!

The best way to search for or find  a particular video is to use Ctrl + F in the browser window and then type in the process you are looking for. It will then jump to the video you are searching for!

A CNC machine for $4000? Really?

Thanks Ryan Dennes!  He sent me an email outlining a new CNC machine that will cut everything up to and including aluminum, for only $4000. The post for it is already baked right into HSM too, so you should be able to send code for it right out of Inventor! It’s called the Pocket NC.

I am NOT saying go rogue and buy one… do NOT say “well Chris and Jim said…”. I have not even seen one in action yet, except for a few Youtube videos. Just saying that if you had an extra $4k kicking around and you know a bit about CNC, this machine may do all we need it to to make projects for CIM. Oh… and it has a fifth axis to boot!  Just let us know how it works out for you.

Here are a few Q & A’s from their FAQ:

How much does the Pocket NC cost?

A Pocket NC costs 4000USD plus shipping.  

What materials can you cut with the Pocket NC?

The Pocket NC can cut wax, plastic, wood, and aluminum.  Basically any materials with hardnesses up to that of aluminum.

What size parts can you make with the Pocket NC?

The travel of the Pocket NC is 4.3 inches (109 mm) in X, 5.0 inches (127 mm) in Y, and 3.5 inches (89 mm) in Z.  How your part fits in this envelope is highly dependent on your setup.

What kind of software will I need to run the Pocket NC?

We are partnering with Autodesk to offer a one-year commercial subscription to Autodesk® Fusion 360™ with each of our machines.  After the one-year period is over, Fusion 360 is free for enthusiasts, hobbyists, and startups and is compatible with Windows and OSx.  You may also use whatever CAD/CAM software you would like, we would be happy to help facilitate the generation of a post processor for our machine.

Are you going to make a machine with a larger work area?

We do plan to design a machine with a larger work area, however it is still a couple of years from being released.

CNC Vocabulary For HSM

Question:

Since I switched from EdgeCAM to HSM, the vocabulary is a little different. Do you have any Key Terms that you use in your classroom that you wouldn’t mind sharing?

Answer:

Of course not! The terminology is a little bit different when you switch from EdgeCAM to HSM, but the concepts are the same. PLTW has not updated their key terms in many years, but I have in my classroom. Please understand that these are definitions that I made up for use in my classroom; I do not utilize definitions from a dictionary. That being said, feel free to utilize the attached vocabulary list.

Also, please feel free to edit the definitions to your liking, and then send them back to me to update them. Thank you in advance!

How do I use an edge finder?

Tired of using the I.L.A.R method of finding the corner of your stock (It Looks About Right…). Then here’s the video for you! This video was made by Tormach, and it shows you how to utilize two different types of edge finders. Thanks Tormach!

This video demonstrates the use of a mechanical edge finder and an electronic edge finder. Essentially, an edge finder is a dynamic indicator of the location of a workpiece edge with reference to the centerline of the spindle to which it is attached. Both versions of the edge finder are used in a similar fashion. The edge finder is put in the rotating chuck and the edge of the workpiece is moved towards the chuck. As the lower cylinder of the edge finder touches the edge, that lower cylinder “kicks” to the left (assuming a clockwise rotation as seen from above). When the kick is observed, the axis of the spindle and the edge of the workpiece are located to 1/2 the diameter of the edge finder. Continue Reading
