·        Objectives:  After completing all the sessions on CAD, students should be able to create simple 2-D and 3-D drawings using Cadkey.  Cadkey is not a CAD software package commonly used in industry.  It is used in classes because it is easy to learn – and much less expensive than most packages used in industry.  Students will learn what features a CAD package typically has, and should be able to learn how to use another package quickly if their jobs require that.

·        It is important that students work through Chapter 1, following the instructions step by step.  If they skip around, they miss important concepts.  However, playing around with options between steps is a good way to learn about the software.

·        The title block must be saved as a pattern.  The drawing the title block will surround is saved as a part.  Only one part may appear on the screen at a time.  However a pattern can be added to the screen while the part is present. 

·        Do Assignment 22, which is the hex nut with a title block around it.

Day 69           Camera Lab 3-2, Lab Volume, Page 364

(in lab)

·        Objective:  Students will learn about the use of the camera as an instrument to collect spatial information.  Most students think of the camera as a way to document events or maybe just a way to remember good times.  However, the information recorded by a camera can be used to make maps, to determine the location of objects in photos taken from space, or even to help solve crimes.

·        Complete Tasks III, IV, and V.

·        Outline Camera Lab #3 report and make writing assignments.

·        If there is time, discuss answers to the questions at the ends of the tasks.

·        Assignment:  Write your portion of the lab report.

Day 71           Electrical Circuits-1, Basics Volume, Page 330

(in classroom)

·        Assignment 29:  electrical circuits.

 

Day 73           Camera Lab 4-1, Lab Volume, Page 392

(in class)

·        Objective of today’s lesson:  Students should understand the objectives of Camera Lab #4, learn the core and auxiliary functions of the flash circuit, and learn how a capacitor works.

·        Emphasize that we are continuing to look at the systems in the camera.  We have looked at the mechanical and optical systems.  Now we’re going to look at the electrical system.  Engineers from different disciplines work on different systems in the camera, and they have to work together because all of the systems in the camera have to function in concert in order for the camera to work properly. 

·        Also emphasize that we will be using the information we learned in the past couple of days – symbols for components of electrical circuits and calculations of voltage, current, resistance, etc.

·        Show slides of Camera Lab 4 Objectives and core and auxiliary functions of the flash circuit.

·        Show slides explaining how a capacitor works

·        Show Video 16:  Demonstration of Camera Lab #4

·        Assignment:  Read Camera Lab #4 Prelab, including the description of an oscilloscope.   Do prelab assignments 1 and 2.  Read Camera Lab #4 procedure for Task #1.  Students should be able to begin doing some of this reading in class. 

 

Day 74           Camera Lab 4-2, Lab Volume, Page 426

(in lab)

·        Objective:  Students learn what an oscilloscope is used for and how it works.  Conduct Camera Lab #4, Task 1.

·        Overview of Camera Lab #4.  Explain what will be measured in each of the 3 tasks.

·        Explain how the oscilloscope will be used to make these measurements.

·        Provide a summary of the Task 1 procedure.

·        Students do Task 1 and gather data.  Be sure all students on each team have the data before leaving class.

·        Point out that there are specific instructions for the Camera Lab #4 report, and they are at the end of the Camera Lab #4 procedure.

·        Assignment:  Make and check calculations for Task 1.  Answer questions under Task 1 in “Report Instructions”.  Read the Task 2 procedure.

 

Day 75           Camera Lab 4-3, Lab Volume, Page 434

(in lab)

·        Review Task 2 procedure.

·        Be sure to call students’ attention to the safety reminder (slide 3).

·        Students conduct Task 2.  Be sure all team members have the Task 2 data.

·        This task gives students another opportunity to connect the oscilloscope to the test board and adjust the display controls.  Team members who did these jobs yesterday will automatically start to do them again today.  But they should not.  Every team member should have a chance to work with the equipment as they will all be tested on their knowledge of the experimental setup and operation of the equipment.

·        This task should not take very long.  Students should have quite a bit of time to work on the assignment.

·        Assignment:  Make and check calculations for Task 2.  Answer questions about Task 2 in “Report Instructions”.  Plan the Camera Lab #4 report and make writing assignments.  Read Task 3 procedure.

NOTE:  Task 3 is usually optional.  If Tasks 1 and 2 take more time than anticipated, Task 3 can be skipped.  But if possible, it should be done.  It gives the students one more chance to solidify their understanding of the equipment and techniques.

 

Day 76           Camera Lab 4-4, Lab Volume, Page 438

(in lab)

·        Review Task 3 procedure.

·        Students conduct Task 3 and collect data.

·        Assignment:  Make and check calculations.  Answer questions about Task 3 in “Report Instructions”.  Prepare your portion of Camera Lab #4 report.

Day 78           Sketching-13, Basics Volume, Page 177

(in classroom)

·        Objective:  Review multi-view drawings.

·        Go over important concepts in making multi-view drawings:  which views are needed, views must be in proper location and aligned, principal dimensions (H, W, D), etc.

·        Assignment 30:  Bertoline, Problem 2.9, items #7 (pg 56), #25 (pg 58), and #46 (pg 59).  Copy the isometric (for practice) and draw front, top, and right side views on rectilinear grid paper.

 

Day 79           Sketching-14, Basics Volume, Page 181

(in classroom)

·        Objective:  Review isometric drawings.

·        Review process for making an isometric drawing – if necessary

·        Assignment 31:  Bertoline.  Problem 2.10, items #3 (pg 60), #16 (pg 61), and #26 (pg 62).  Copy the multi-view drawing on rectilinear gird paper (for practice) and sketch the isometric on isometric grid paper.

 

Day 80           Section Views-1, Basics Volume, Page 304

(in classroom)

·        Objective:  Students will learn how to show internal features of an object using section views.   (Most students have trouble with making a section view because they can’t visualize what the object looks like when it is cut open.  Having them make an isometric drawing of the cut object seems to help them understand what the 2-D section view is showing them.)  The emphasis today will be on full and half section views.

·        Explain the uses and importance of section views.

·        List the types of section views and explain when each is used.

·        Show slides that illustrate full and half section views. 

·        Some points that are important to make:

o       Proper way to make section lines (crosshatching)

o       How and where to show the cutting plane and the direction the arrows should point

o       In general, there are no hidden lines in section views.  The idea is to show the object cut open so that the internal features are visible.

o       In a half-section drawing, the line that separates the external and internal views is a center line.

·        Show Video 17:  Drawing Full and Half Section Views

·        Assignment:  Read Bertoline, Section 3.1 – 3.4.  Do Assignment 32 from the drawing packet– make the full and half section views and draw an isometric of the full section on isometric grid paper.

 

Day 81           Section Views-2, Basics Volume, Page 317

(in class)

·        Objective:  Students will learn how to make section views other than full and half sections.

·        Name the other types of section views and show pictures of them.

·        Explain what students will see in Camera Lab #5.  Explain how it is related to the other camera labs. Tell students what will be expected in the Camera Lab #5 report so they can gather the information they need while at the OSU lab.

·        Assignment 33 from the drawing packet.
