99.96
 
6. Using six sigma, what is the maximum number of manufacturing errors you can you have per million products?
0.004
0.4
3.4
3400
 
7. In the DMAIC method of six sigma, in the improve phase three of the four steps are: ____________________________________________________________________________
 
8. What methodology is used by companies when they want to release a new product created from scratch?  DMADV or DMAIC?
Explain why you think this to be true.  
__________________________________________________________________________  
 
9. According to six sigma, and the manufacturing wheel, when launching a new product, who’s input is most important? Why?
__________________________________________________________________________  
 
10. List three of the industries that have found success using six sigma. _____________________________________________________________________

Step 3: Count your M&M’s

Watch the video below: CnJ Manufacturing Math and Statistics Part1: Counting, and take note of how many M&M’s you estimate to be in a small bag, and a large bag.

CnJ Mfg Stats Student Template

Copy and paste the questions below into a google doc, an LMS, or a Word doc, and hand them in to your teacher.

Conclusion: Counting

  1. How close were your estimates to reality?
  2. Compare the # of each color in the small bag with the big bag. Describe your comparison. What do you see in the above data?
  3. Compare the amount of colors in your small bag to what the video says they should be. was your data the same as in the video? Compare and explain your results.
  4. Put your data from the small bag above into the sheet labelled Colors in the column labelled YOUR DATA.

Step 4: Color Analysis

Watch the video below: CnJ Manufacturing Math and Statistics Part 2: Color Statistics, and open your excel spreadsheet from Step 3 and follow along. Be sure to save your work when done.

Step 4 Conclusion: Copy and paste the questions below into a google doc, an LMS, or a Word doc, and hand them in to your teacher.

Conclusion: Color

  1. Will the data for the color be the same from year to year? Why or why not?
  2. What do you think could’ve happened to make Jonny’s data incorrect?
  3. Define the following terms:
    Mean
    Median
    Mode
    Standard Deviation
  4. Draw the histograms in your notebook if you cannot get Google sheets to make them correctly.

Step 5 Measurement Analysis

Watch the video below: CnJ Manufacturing Math and Statistics Part 3: Measurement Statistics, and open your excel spreadsheet from Step 3 and follow along. Be sure to save your work when done.

Step 5 Conclusion: Copy and paste the questions below into a google doc, an LMS, or a Word doc, and hand them in to your teacher.

Conclusion: Size

  1. Will the data for the size be the same from year to year? Why or why not?
  2. What do you think the shape of the histogram should be in an ideal situation? Describe it in words.
  3. How do your histograms compare to the ideal situation? Describe why you think this is true.
  4. Draw the histograms in your notebook if you cannot get Google sheets to make them correctly.
  5. How does what you have learned in this activity deal with the concept of Six Sigma in Manufacturing? Explain fully.

This activity is suitable for use by students via distance learning as well.

How to hold material in the xsTECH

What’s the best way to hold _____________ in my xsTECH router? From strap clamps to double sided tape, we have it all! Learn how to hold everything including circuit boards, flat stock, and blocks in this video.

Can you believe that you can use strap clamps, sticky tape, and all kinds of ways to hold stuff down… sometimes a little ingenuity helps as well. The strap clamps it comes with are pretty cool too, but they won’t hold down everything.

Have a great way of holding something down? Let us know!

Will a vice fit in an xsTECH?

Answer:

That’s a fair question. When trying to come up with an aswer though, you’ll have to do a bit of research, as it will depend on what you’re machining. Also, there are many different one’s out there.

Luckily Jim did some research for us… maybe this video will help guide you to an aswer.

Basic Part Creation Using Autodesk Fusion 360

Download the Worksheet Download Hand-In

Student Notes: Download the Worksheet, dimension the parts using the given scale, then make them in your 3D modeling software! Here is a project to help you and your students get acquainted with Autodesk Fusion 360. There are eleven parts to make, and they are all pretty simple. There are many examples of subtractive and additive 3D modeling techniques as well as extensive use of the Hole tool. There is a Loft as well.

Teacher Notes: Download and hand out the Worksheet, so that students can figure out the dimensions and take notes, then hand out the Hand-In file electronically so that students can paste a snip of the parts into it so that you can grade it.

These parts originated from a worksheet I used to use when we used t-squares and triangles on a drawing board so some of the more “seasoned” professionals may get a kick out of them!

This would be another activity that you might be able to use as a distance learning project during the COVID-19 outbreak as well.
