Experiences

We design and develop a variety of mixed reality, multi-sensory, and interactive digital experiences to increase learning engagement, deepen the quality of learning, and broaden learning access. These learning experiences are primarily for learning manufacturing or micro/nanotechnology and are broadly grouped into (i) apps, (ii) simulations, and (iii) haptics.

APPS

Product Disassembly and Inspection

These apps enable learners to manipulate, and virtually disassemble various parts and products (representing high-volume manufacturing processes), while receiving scaffolded guidance. This work has been published and recently won two best paper awards at ASEE 2021.

Machine Shop Skills

This set of AR apps enable blended learning of machining hands-on skills. These instructional modules can be experienced before a student steps into the machine shop to prepare, or during the course to augment in-person instruction.

2.670 Flashlight Instructions and Mill Intro

Download Vuforia View on a tablet/iPad (this experience was made for big screens).

Hold your tablet screen landscape for best experience.

GET THE APP

Open Vuforia and select the QR scanning tab on the bottom. 

Scan this QR code to load Experience. It should be titled “2.670 Learning App”.

To bookmark the app for later use, click on the three dots in the top right corner and click “Share”

Then click on the “Bookmark” button.

Milling introduction

Download Vuforia View on a tablet/iPad (this experience was made for big screens). 

Hold your tablet screen landscape for best experience.

GET THE APP

Open Vuforia and select the QR scanning tab on the bottom. 

Scan this QR code to load Experience. It should be titled “2.670 Learning App”.

After it says that your experience server has been set, scan the appropriate thingmark to whatever experience you want to view (thingmark below is one example)

        • ******make sure the thingmark you’re scanning is the right size and orientation (notch is on top) — both of these things are set in Vuforia Studio
        • One thingmark can have multiple experiences on it so make sure you’re selecting the right one (e.g. Machine Shop AR)

 

1. Landing page: Click either the Introduction or FAQ

2.Scan the thingmark to see the AR model

    • ***make sure the thingmark is in the right place, size, and orientation as it is in Vuforia Studio

3. Tabs on the left represent categories and you can click on them to see the dropdown menu with expanded content

    • Select an option from the dropdown menu and a popup will appear on the right of the screen with information

4. Click anywhere in the middle of the screen to clear OR hit the “clear” button on the top left

5. If you want to hide the AR CAD, hit the lightbulb on the top right of the screen to show and hide the model as needed

FAQ

  • General
  • What is a burr?
    A burr is a rough edge or ridge that results from a cutting or machining operation.
    burring, define, definition, sharp, edge, file

  • Inspection

  • What features can I measure with calipers?
    Calipers allow you to measure the distance between two points with precision of +/- .001″. Those points can be external features (such as an external diameter or height of a shoulder) or internal features (such as an inside diameter or depth of a hole).
    measuring, caliper, measure, increment, micrometer

  • What measuring equipment should I use for specific tolerances?
    Different measuring devices hold different tolerances. Tape measures and scales (rulers) are commonly used for tolerances of +/- 1/64″, calipers for tolerances of +/- .001″, and micrometers for tolerances of +/- .0001″.
    tools, measure, measuring, tape, tape measure, caliper, micrometer, increment

  • How do I calculate the depth of a thread?
    Toggle Content
    threading,

  • How do I check hole locations?
    Toggle Content
    hole position,

  • What does “squaring a block” mean?
    Squaring a block refers to the process of machining faces of a cuboid shape / rectangular prism (6 sided) so that all surfaces are at 90 degrees to one another.
    square, squaring, mill, block

  • Filing

  • Why only file in one direction?
    File teeth are directional, so filing only
    filing, removal, deburr

  • What is draw filing?
    Draw filing is a technique for quick material removal in which the user holds the file handle in the left hand and the tip of the file in the right hand. Material is removed by applying downward force of the file on material while pulling the file towards the user.
    draw file, removal

  • What are the different kinds of files? And how do I know when to use them?
    Files differ from one another in shape, material and tooth configuration. The proper selection of a file depends on the type of material being worked, the shape of the cut, and the desired surface finish. Files that remove material aggressively will leave a rough surface finish – and those that leave a fine surface finish remove very little material at once. For more information see (insert good reference like https://paulbudzik.com/tools-techniques/Files/files.html )
    file, mill, bastard, double cut, needle

  • How do I know if the file is dull?
    Files can dull over time with general use and when used on particularly hard materials. You will know the file is dull or the material is too hard to file if you can’t observe chips generated from the effort.
    dull, trouble shooting

  • Why do I need a handle on my file?
    The feature of the file that mates with a handle is called a tang. This feature, unprotected by a handle, is sharp and can cause injury to the hand of a user if handled improperly. This is especially true when using a file on a part spinning in a lathe.
    dull, trouble shooting

  • How do I clean my file?
    The tool used to clean a file is called a file card. It works by mechanically brushing file chips from out between the teeth of the file. If not cleaned properly, dirty files won’t remove material properly and can mark the surface of the material being filed.
    file card, brush, clean, deburr

  • Simulations

    AFM Image Artifact Simulation

    This simulation enables visualization of imaging artifacts of the Atomic Force Microscope (AFM). Students can manipulate parameters such as tip shape, surface profile, and tip cleanliness, and compare the actual surface to the imaged profile.

    Contact us if you are interested in using this simulation.

    Kits

    AFM Haptics and Visualization

    This visualization and haptic feedback controller kit enables students to see and “feel” the forces acting on the Atomic For Microscope (AFM) tip to enable multi-modal learning of mechanical principles on the nanometer scale. This work was most recently published in Nisal Ovitigala’s thesis.
