Your students really need to know how things are made in industry, so below are some resources to help you get started with the learning process. My students became an “expert” in one particular field, picked a topic, and made a brochure about a specific manufacturing process. Part of their research was to find a great video that explains the process. The links to all of the videos, as well as some of their brochures as well.
CNC Milling is the most common form of computer numerical control (CNC) machining, performs the functions of both drilling and turning machines. CNC mills are categorized according to their number of axis and are traditionally programmed using a set of codes that represent specific functions.
Brochure coming soon…
CNC Turning refers to the automated machining process of shaping material, such as metal, wood or plastic, using a computer numeric control (CNC) machine. Turning is usually done when making round parts.

Waterjet Cutting: is a form capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance.
Brochure coming soon…
Laser Cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.

Drop Forging is the process of heating metal and hammering it in to a special die (cast die) to produce a final product. Manufacturers use the drop forging process to produce hardware products which need to be strong and durable.
Investment Casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term “lost-wax casting” can also refer to modern investment casting processes.Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes, refractory materials and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys.

Sometimes you just have to see it to understand it. I know because I am a visual learner. So here it is: How to make the container from start to finish….. Physically speaking! From a block of Renshape to final product. No code or 3D modelling at all!
If your looking for the Inventor tutorials for the container, look here: http://chrisandjimcim.com/how-do-i-make-a-container-in-inventor/Lets start with the fixture:Then we can machine the base:And now for the lid. It gets machined on the back side of the base!Next we use a bandsaw to split the top from the base:Want to manually face the part? Here is how:Last but not least…. How to put a surface on your container:Continue Reading
Sorry it took so long, but here is some info on how to make the Dual Handshake Module Jim & I designed two years ago. All files are attached in a zip file at the link below. These files include:
All inventor part files: tweak to your heart’s content
STL and Makerbot files
DXF files for the cover.
Various pictures to help with assembly
PDF of this Project
Handshake Module ContainerItems above in red are not needed. These were from version 1. This brings the cost down, but requires you to use less costly servo extension wires for the cables.
Soldering Diagram (Better one coming soon!)
Solder 4N25 IC’s in place. Use caution and work quickly as they are heat sensitive.
Solder LED’s and Headers in place (or wires, your choice!)
Knock the corners of the board off so it fits into the container.
Snap the board into the container.
Place the spacers on top of the board.
Place the cover on carefully.
Put the 4-40 screws through.
Put the nuts on the back, tighten carefully.
Tips and Tricks:
Paint the cover BLACK before you peel it, and the black dots will indicate where the black wires go! The arrows indicate the direction of the communication: Tail of the arrow = the signal “Sender”, head of the arrow = signal “Receiver”
Container back prints with space for 4-40 nuts.
Container front prints so that the board will snap into the built in standoffs. IN ORDER TO FIT, YOU HAVE TO KNOCK THE CORNERS OFF THE BREADBOARD. I used a belt sander.
To assemble the parts, see below. Be sure to use the printed spacers to stop the board from wiggling around!
How do I get my Lynxmotion robot to connect with my computer? I have the new USB version of the SSC-32.
It is a little bit different, in that there is now only one switch, and it will connect every single time, as long as you follow the right steps. The steps are listed below and can be downloaded as a PDF from the link as well. Pay attention to the last step! Even if you are not using bluetooth turn it on.
