Procedures:

Your grade in this course will be determined from your performance on:

v  Drawings,

v  Quizzes,

v  Midterm and final exams.

 

The course consists of lectures and laboratory sessions, with new subject areas covered through reading assignments, lectures, and demonstrations. Each lecture is followed by drawing assignments using the theory and principles of the subject areas. Students are required to attend the class during the assigned times. Open lab sessions scheduled throughout the week are also available for the student to complete assignments. These open labs are monitored and are available on a “first come, first served” basis.  Students may use the graphics labs only to work on specific assignments from the MET department.

 

Attendance is expected and required during all class and lab periods. If you miss a class, it is your responsibility to get the assignments for that day and to have your homework turned in on time. Any student needing additional help should make an appointment with his/her professor. Also, there are ample open lab sessions available for the student to complete assigned work.

 

(Some of the materials in this page are obtained from the website of Prof Greg Conrey).

 

Drawings

All assigned drawings (assignments) are to be turned in at the beginning of the class period on the announced due date. Any drawing turned in after the beginning of the class period will be considered late and will lose 5pts out of a possible 10pts. Drawings are graded on technical accuracy, layout, and professional appearance. One drawing grade will be dropped before the final grade is computed.

 

Quizzes

Quizzes are given without prior notice. They are based on the reading assignment for that day and previous lecture materials. Quizzes are given at the beginning of the class period and cannot be made up. One quiz grade will be dropped before the final grade is computed.

 

Exams

A mid-term exam will be given. Also, a final exam or final project will be given or assigned.  Each exam will be comprehensive and will include previous reading assignments, lectures, and drawings.  There is a time limit on each exam. Exams can only be made up with a legitimate excuse and at the professor’s discretion. A grade of zero will be assigned to any missed exam. No exam will be dropped.

 

Grading policy:

 

The course grade is broken down as follows:

Drawings (Assignments)                   35%

Quizzes                                               25%

Midterm                                             20%

Final Exam                                        20%

TOTAL                                               100%

 

[90 - 100% = A,   80 - 89% = B   70 - 79% = C   60 - 69% = D   Below 60% = F]

HW1- Lettering Assignment:

 

The first page of this assignment which was handed out is due Mon Aug 30th (or Tuesday Aug 31st depending on the section you are in).  Try to write the letters neatly and with correct spacing, height and width. "Any stroke sequence that you choose is ok," as long as they are well written. If the guide-lines are not visible, draw them lightly with correct spacing. If you need, you can draw some vertical guide-lines, so that you can work on the width of each letter.

Just don’t rush to fill the pages, as if the letters are not written correctly, I will ask you to do them several times! The second page was also handed out.

 

HW2- Scales Assignment:

 

This assignment is due Wed Sep 1st  (or Thursday Sep 2nd. Determine the measurements and fill the corresponding tables (Mech Metric, Civil, Architect’s and combination scales respectively). Solutions were emailed.

 

 

HW 3 – Part 1 and 2: Sketching Assignment:

 

The 12 objects assignment (figures 13 to 24 of this file) and also the second part of HW 3 which were handed out in class are due Mon Sep 20th (or Tues Sep 21st depending on the section you are in).

 

Part1: Sketch the parts neatly, following the correct alphabet of lines (types of lines, thicknesses, etc) and also the precedence of lines. Also draw the construction lines and the miter line for each object.

  Solution

Part 2: Make freehand sketches of the two views given on the first page (following the correct alphabet of lines). Also for the second page, find the missing lines in multiview drawings.

  Solutions: Page 1                 Page 2

Part 1: 4 pts each (total of 48)

Part 2: Sketches 14 pts each (28 total)

Part 2: Missing Lines 1pt each (24 total)

 

4- Multiview sketching assignment:

 

Use this A3 sheet format and prepare your sketching paper. Read this document very carefully and follow the instructions. The weight of this assignment is more than previous ones. So take it seriously and sketch it very neatly. This is due Wed Sep 22th (or Thurs Sep 23st depending on the section you are in).

 

The formulas for finding A1, A2, B1 and B2  (in inches):

 

A1 = A2 =  (10.5 – 1.5 – W- D)/2 = (9- W- D)/2                                 1.5” for the gap between front and side views.

B1 = B2  =  (8 – 2(0.375)- 1.5 – H- D)/2 = (5.75- H- D)/2                  1.5” for the gap between front and side views. The title block height should be taken away from the total 8”.

 

(where H= height, W= width and D= depth of the object).

 

 

5- Multiview sketching assignment:

 

Use this A3 sheet format and prepare your sketching paper. Read this document very carefully and follow the instructions. The weight of this assignment is more than HW4. So take it seriously and sketch it very neatly. This is due Wed Sep 29th (or Thurs Sep 30th depending on the section you are in).

 

 

Assignment 6:

Study Isometric Drawing-1 and sketch the isometric drawings in slides 41 and 42. This is due Monday Oct 4th or Tues Oct 5th depending on the section you have. There is no need to show the extension and dimension lines. The isometric papers given to you has 4 blocks per inch. So you can consider a scale of 1 and draw the objects (either two on one page (if they fit) or one on one).  More isometric papers are available in a letterbox outside my office.

 

 

Assignment 7 or Bonus Assignment on Oblique drawing:

 

Follow the instructions in this file and hand in this assignment on Wednesday Oct 6th (or Thursday Oct 7th). The two objects are shown here in figures 32 and 35.

 

 

Assignment 8:

Part 1: Use a normal grid paper and with the small font (each letter one block high) introduce yourself and write about your hobbies, your future goals and anything else that you wish. I want to get to know you more. This should not be less than 150 words. Use Gothic letting for this introduction. If you are using a 10 by 10 rid paper, each letter could be a bit larger than one block high. Write very neatly.

 

Part 2: Draw isometric pictorial sketches of these objects (page 569 & 570 of your book). Don’t use a page for each, instead sketch 4 to 6 of them in one page.  So you just need to enlarge them a little bit. You can use normal grid paper or print out the isometric paper from internet and sketch the parts. I want you to think about dimensions and choose them proportionally.

 

This is due Wed Oct 13th (or Thurs Dec 14th )

 

 

Solidworks:

 

Assignment 9 (In-class): Make the Tool Holder (Fig 7.58) in this file Multiview-Projection Exercises

 

Assignment 10: Create a solid model of the Finger Guide Fig 7.56 in this set of drawings. This is due Monday Nov 8th (or Tuesday Nov 9th depending on your class). Email the sldprt file to metengcomp@gmail.com.  Rename the file to show your name: HW10-John-Smith.sldprt and when you send it, choose this subject for your email: HW10-T-R or  HW10-M-W.

 

Assignment 11: Create a solid model of the Roller Stud, Fig 7.78 in this set of drawings. This is due Wednesday Nov 17th (or Thurs 18th). Print out the drawing file after working on all dimensions. Remember that you should make each feature based on the dimensions given to you!

 

You can also work on the Rod Support or 7.57, but this one is just for practicing. Try to make other parts as well.

Assignment 12 (In-class): Create a solid model of the Cam, Fig 7.63 in this set of drawings. This is an in-class assignment for which you need to create the drawing as well. Remember that you should make each feature based on the dimensions given to you!

 

Here is the instruction for making this part.

 

Assignment 13: Practice problem- Create a solid model of a part shown in page 37 in this file. This is Remember that it is easier to use the method of revolving in which you just need to introduce a half-cross-section of the cylindrical part and revolve it about the z axis. Then add the base and ribs. Use the normal extruding method or rib tool for making the first rib, then use mirror feature to copy it using the front and right planes.

 

Here is the instruction for making this part.

 

   Also work on part 7.61 or the bearing and see how you change the appearance of the part.

 

Here is the instruction for making this part.
