The videos below are for instructional purposes and are not to be distributed to others. I have saved most of the videos onto your computer. If you look on the C drive and in the folder HCHS, you will find higher quality videos that what you download from this webpage.


Eighth Week Overview

Assignments due from previous weeks!!!

1. Practice Test B (Due Tuesday)
2. Oil Pump Drawings  (Due Wednesday)

Assignments due this weeks!!!

1. Hex Bolt (Due next Friday October 21)
2. Round Head Bolt (Due next Friday October 21)
3. Flat Head Bolt (Due next Friday October 21)

There are a total of 6 Fasteners that you will make over the next two weeks. With each of these assignments there are two questions in a spreadsheet quiz, making a total of 12 questions. These questions will check to see that everything is correct in your model. So as you finish the parts, please answer the appropriate questions. All the questions ask for the volume. Remember to get the volume, you have to right click on the part name and go to iproperties and to the physical tab. Click update and you will have your answer. If you are getting the wrong answers, then email me the part and let help you. As long as the answers are correct, just hold on to all the files and send them to me on October 31. Remember that next week is Spiritual Emphasis week, so there will be less class time. However, as you make them, the models should get easier and faster. The links below are the picture, the spreadsheets for the iparts and the spreadsheet quiz that you will need for all 6 parts.

Hex Bolt
Due Friday October 21 - When you look at the picture, you will see at the top a bolt designation. For the Hex bolt, you will see 1/2 2-1/4 13NC Hex Hd. The 1/2 refers to the shaft diameter. The 2-1/4 refers to the length of the bolt from the shoulder to the bottom. The 13NC refers to the number of threads per inch, abbreviated TPI. NC stands for Normal Coarse. All the dimensions are based upon these three numbers (Diameter, Length, and TPI) and most of them are based upon the diameter. For example, the thickness of the head is designated as 2/3D or 2/3*Diameter. The objective is to create 3 user parameters which is explained in the video and then every dimension will be a formula. So the entire design of the bolt will be controlled by those three numbers.

Creating the ipart
Due Friday, October 21 - Basically, we will be creating a spreadsheet using Microsoft Excel and placing the 3 main parameters into the spreadsheet and imbedding it into the part file. This will allow you to select a certain row of the spreadsheet from the browser and the program will pull the dimension from the spreadsheet and build the part. It is important to check many of the different bolts to make sure there are no errors. Otherwise, the errors will be propagated to all the following parts. So it is important to fix any errors now. In a few cases, I have run into some problems with Excel and Inventor working together. If you have this problem, please bring this up with me and with Mr. Flowers. If we cannot get this resolved, then you will have to manually change the parameters to be able to answer the questions on the quiz. You can accomplish this by going to Save As and giving it an appropriate name. Then change the parameters. However, with this method, you will get an error message in the threads. You will need to edit the thread and set it to the right diameter. This is all explained on the video. If you get the first two questions on the quiz correct, then proceed to the next problem. If there is a problem and you cna not resolve it, then email me the part and I will look at it and get back with you.

Flat Head Bolt
Due Friday October 21 - Rather than re-inventing the wheel, we will make modifications to the Hex Bolt. But you must "Save as" first and give it an appropriate name. If not, then you will mess up your hex bolt and you do not want to do that. This way, you keep the ipart table and many other features of the model. This should help you in editing models and fixing problems as they occur.

Round Head Bolt
Due Friday October 21 - We will create the Round Head Bolt using the same procedure we did for the Flat Head Bolt
