Tutorial 1: Extrusions, Sketching, and Cuts

Introduction

Extrusions are one of the most basic ways to design a part in Pro/E, and sketching is an important part of the design process. In this

section, you will learn basic operations by creating a simple part using an extruded protrusion. You will then modify the part using a cutting

operation.

Starting Pro/E and Creating new Part

1. Start Pro/E Wildfire. 2. Select [File] -> [New] from the menu bar. The dialog shown in Figure 1.1 will pop up.

[Figure 1.1]

3. Type the part name [Example1] in Text Box. 4. Click [OK] button (or press Enter Key). You will see the screen shown in Figure 1.2.

Alternative Method for Creating Base Part

In this section, you will use Intent Manager to create the same part that was created in the previous section. Many people find this method

easier to use - you have less work to do since Pro/E is making assumptions about the geometry you are drawing. In future tutorials and

problems, you can use either sketching method. However, the tutorials will demonstrate the use the first method, without Intent Manager.

1. Select [File] -> [New], and type the part name [Example2B] in Text Box. 2. Click [OK] Button. 3. Select the Extrude Tool icon from the tool bar at the right of the screen. 4. Select the Sketcher icon from the dashboard, and click the reference plane marked as FRONT. 5. Click the Sketch button from the Section menu. Pro/E will switch to Sketch Mode. 6. Use pan and zoom operations to change the viewing so that you see the coordinates as shown in Figure 2.14. 7. Now sketch the shape of the cross-section shown in Figure 2.14. Follow the steps below:

Select the Line icon from the tool bar at the right of the screen.

Click points A and B with the left mouse button, and then press the middle mouse button.

Select the Arc icon from the tool bar at the right of the screen.

Click points B and C with the left mouse button, and then press the middle mouse button. The letter "T" should appear near

point B. This indicates that the arc is tangent to the line.

Select the Line icon again.

Click points C, D, E, and A with the left mouse button, and then press the middle mouse button.

[Figure 2.14]

8. You should see dimensions drawn very faintly on the sketch. These indicate weak dimensions, meaning they can be overridden by manually dimensioning the drawing. You can change these dimensions by performing the steps below:

Select the Modify Dimension icon from the tool bar at the right of the screen.

Click on the dimension at point A in Figure 2.15, and change the value to 240. You may need to pan and zoom to see the image.

Select the Modify Dimension icon again.

Click on the dimension at point B, and change the value to 65.

Change the value of the dimension at C to be 180 if necessary.

You should notice that the dimensions you changed are now shown in yellow.

If you wish to add dimensions in locations where there are no weak dimensions, use the Add Dimension Icon. Manually entered

dimensions will override weak dimensions.

Tutorial 6: Sweeps and Blends

Introduction

Sweeping and blending are useful techniques for designing parts which may be difficult to model with extrusions or revolves. Unlike these

other modeling techniques, sweeps and blends allow for parts with varying cross-sections and parts that twist or bend. In this section you

will created a constant cross-section U-shaped part using a sweep and a vase using a blend.

Creating a Swept Part

1. Start Pro/E Wildfire. 2. Select [File] -> [New] and name the new part [Example6A]. 3. Select [Insert] -> [Sweep] -> [Protrusion] from the menu bar. 4. Select [Sketch Traj] from the Menu Manager. This will allow you to sketch the trajectory of the sweep. 5. Select the plane labeled FRONT, and select [Okay] from the DIRECTION menu in the Menu Manager. 6. Select [Default] from SKET VIEW. Pro/E will switch to Sketcher Mode. 7. Select [Sketch] -> [Intent Manager] from the menu bar. 8. Draw the path shown in Figure 6.1 as follows:

3. Click the OK button to accept the default parameters, and close the Analyses window. 4. Select [Run] from the Menu Manager. 5. Select [Motion (Standard/Motion)] in the Run window, and click the Start button. If you did everything correctly, you should see an

animation of the assembly with the driver completing one revolution in 10 seconds. If you get a message saying that there was an error

while compiling the equations of motion, you may need to define path and environment variables to run a C++ compiler.

6. Select [Results] -> [Animate] -> [Start] from the Menu Manager. This will bring up an Animate window with normal play, stop, etc. buttons. Experiment with these buttons to view an animation of your assembly. Click the link below to view the correct animation.

Assembly Animation

7. Close the animation window and select [Done/Return] from the ANIMATE menu. 8. Now you will plot the velocity of the end of the guide. To do this, you will first need to create a datum point. Select [File] -> [Open] from

the menu bar and open the guide. A new window should open.

9. Select the Datum Point icon from the tool bar at the right of the screen. 10. Select the front surface of the guide, hold down the Control key, and select the axis of the hole through the guide, as shown in Figure 3.6.

11. Click the OK button from the Datum Point window. 12. Select [File] -> [Save] from the menu bar and click the green check button to save the part. 13. Select [File] -> [Close] from the menu bar. 14. In the window with the assembly, the guide should be automatically updated. You will need to run the Motion analysis again to obtain the

velocity profile of the end of the guide. Select [Motion] -> [Run] from the Menu Manager.

15. Select [Motion (Standard/Motion)] in the Run window, and click the Start button. You should see the same animation you saw in step 6. 16. Select [Results] -> [Graph] -> [Pt Velocity] from the Menu Manager. 17. Select on the point you just created on the guide. 18. Select [Mag] from the Select the Component window, and click the Accept button. 19. Select the OK button on the Select window. You should see the velocity profile shown in Figure 3.7. You can use the menu bar on this

window to format, save, and print the graph.

Introduction

In this tutorial, you will perform a thermal analysis of the Inverted Slider Mechanism to determine the minimum and maximum temperatures

of the end of the guide link. You will learn how to apply boundary conditions, model different materials, and run and plot thermal analyses.

Building the Thermal Model

1. Start Pro/E Wildfire and open the Inverted Slider assembly. 2. Select [Applications] -> [Mechanica] from the menu bar. A window will be displayed containing the unit information for the assembly.

Note the units displayed, as all analyses you will perform will not show units, and click the Continue button on this window.

3. You will now define the materials of the assembly. To make the thermal analysis more interesting, the materials will be different than those originally used for the motion analysis. Select [Thermal] -> [Materials] from the Menu Manager.

4. Select AL6061 from the Library, and click the Add Material icon . 5. Select the Assign->Part button, hold down the Control key, and click on the two pivots, the driver, and the slider. 6. Select the OK button from the Select menu.

7. Select STEEL from the Library, and click the Add Material icon . 8. Select the Assign->Part button, and click on the guide. 9. Select the OK button from the Select menu and close the Materials window.

10. You will now set the temperatures of the pivots. Select [Bndry Conds] -> [New] -> [Prescr Temp] -> [Surface] from the Menu Manager.

11. In the Prescribed Temperature window, change the name to Pivot1Temp. 12. Click on the arrow under Surfaces, select the bottom surface of the first pivot (the one attached to the driver), and click OK from the

Select window.

13. Set the temperature to 75 degrees. You should see the windows as shown in Figure 5.1.
