Integrating CAD/CAM/CAE and Composite Molding Technologies in a Research Experience

Abstract

This paper discusses the research experience of a student who integrated design and manufacturing functions to improve a brake shoe used on a band saw. The CAD/CAM and composite tooling technologies selected for this project were primarily based on student’s undergraduate and graduate course work. The scanning/digitizing and rapid prototyping technologies were also studied. This study shows the integration of these technologies could be successfully achieved.

Introduction

An Independent Research course (IET 791) in the Department of Engineering & Technology at Central Michigan University provides a venue for graduate students to showcase their comprehensive knowledge and skills. It serves as an important tool in evaluating their abilities in handling real world problems. This paper discusses the research experience of a student who integrated design and manufacturing functions to significantly improve a product.

A braking shoe used on a band saw was first selected for the project. This defective part, which was made of cast iron, was broken near the larger hole as depicted in Figure 1. The primary focus of this project was on developing an effective approach for producing a much stronger replacement.

An initial evaluation based on brake shoe design suggested a composite material would be preferred over a metal. A composite material was selected as the substitution for cast iron. This is because they have inherent properties that provide performance benefits over metals. It is well known that cast iron has built-in notches that can catastrophically fracture under impact. Composites are composed of a matrix material reinforced with fibers which are the primary load carriers of the material. The matrix component permits the load to be transferred from fiber to fiber providing good damping characteristics and high resistance to fatigue1,2. In addition, a
