## The Cam Tutorial

Welcome

This tutorial gives step by step instructions to design and create a model of cam. No prior experience of using Solid Edge or Engineering Reference is required for this tutorial. However an engineering knowledge on the design of cam will be useful.

Tutorial Guide

Each step in the tutorial demonstrates the task to be performed with Graphical User Interface (GUI) of Engineering Reference. Some tasks may require interaction with Solid Edge also. This tutorial should take about 15 min to complete

Introduction

In this tutorial you design and create a model of cam with the following specifications.

• Pitch Circle Dia : 160 mm
• Max Lift : 30 mm
• 0 to 110 deg segment with Simple Harmonic rise to a lift from 0 to 15
• 110 deg to 240 deg segment with Double Harmonic rise to a lift from 15 to 30
• 240 deg to 360 deg segment with Simple Harmonic fall from 30 to 0

Follower Roller Dimensions

• Width : 12 mm
• Eccentricity : 0

You will do the following tasks in the design of cam

1. Start Solid Edge and Engineering Reference
2. Entering basic Inputs like Pitch Circle Diameter, Maximum Lift and Follower Roller Dimensions
3. Setting parameters and calculating the output for each segment
4. Creating the 3D Model

Start Solid Edge and Engineering Reference

Engineering Reference environment is accessible through Solid Edge environment only. So if Solid Edge is not running currently, start Solid Edge from the windows start menu.

To start Cams Module, Select the Engineering Reference tab from the Edge bar. Scroll down the edge bar until you find Cams

Double click on Cams to start the Cams Module

Entering Basic Input

From the Engineering Reference interface start Cams module.

Enter the Pitch Circle Diameter, Cam Width   and the Follower Roller dimensions.

• Pitch Circle Dia : 160 mm
• Cam Plate Width : 12 mm

Follower Roller Dimensions :

• Width : 12 mm
• Eccentricity : 0

Leave the other parameters in the GUI to default

Setting parameters and calculating the output for each segment

Now switch to Calculated Results tab to input the details of each segment of the cam. Input the following parameters for the segment 1

• Profile = Simple Harmonic
• Ending Angle = 110
• Final Lift = 15

Click on Calculate to display the results for the first segment. The segment count moves to the next segment.

The segment count is set to 2 now. This indicates that the calculation is complete for the first segment and input is required for the segment 2. Input the following parameters for the segment 2

• Profile = Double Harmonic
• Ending Angle = 240
• Final Lift = 30

Click on Calculate to display the results for the second segment.

The segment count is set to 3 now. This indicates that the calculation is complete for the second segment and input is required for the segment 3. Input the following parameters for segment 3.

• Profile = Simple Harmonic
• Ending Angle = 360(This is automatically set)
• Final Lift = 0(This is also set automatically since the cam has to return to its original position)

Click on Calculate to display the results for the third segment.

Creating the 3D Model

Use the Create button to create 3D model of cam.

: If the current environment is a Part Environment then a new part is created. Use File, Save As command in Solid Edge to save the file to a different location. If the current environment is Assembly Environment then an instance of the 3D model is added to the assembly and the assembly is saved.

This concludes tutorial

In this Tutorial you have learned how to use Cams Module to design and create a 3D model of cam for the given inputs
