Design through Manufacturing Approach for Kinematics Class

Yeu-Sheng Paul Shiue Mechanical Engineering Department Christian Brothers University Memphis, TN 38104 USA

Abstract

The design through manufacturing approach for the Kinematics class brings students into the design process at an earlier stage. Students in the Mechanical Engineering Department at Christian Brothers University learn the traditional and modern manufacturing processes including machining tools, CNC programming, and welding in their sophomore year. In order to maintain students’ manufacturing skills through interaction and hands-on experiences, an industry or community-related class project must be carefully selected. Applying classroom knowledge to a day-to-day product is the best way to make students realize the importance of the subject. In the junior level Kinematics class, instead of building traditional simple four-bar linkages or slider-crank mechanisms, a project is selected to apply four-bar linkage, gear and gear train, relative motions to a day-to-day product. The current project is to design and manufacture an automatic feeding device for children who have disabilities. The main focus of this project is on the mechanism design with a complete kinematics analysis of the critical components. The final product is evaluated and tested by the children at Shrine School in Memphis, Tennessee. This approach encourages students to review their manufacturing skills and shows them the importance of teamwork and communication while learning basic kinematics.

Introduction

Kinematics is a major part of the curriculum in mechanical engineering. Traditionally, the instructor teaches kinematics by demonstrating theory and analysis to the students with simple mechanisms, such as the slider-crank, the four-bar, and quick-return mechanisms. In some cases, small class projects are assigned for students to construct basic mechanisms as mentioned above. The materials used in these projects are usually wood or aluminum. Students will definitely be able to learn the position analysis of the mechanism and compare it with the analytical results. However, it is not possible to study the velocity and acceleration of the mechanism without a
