The Department of Engineering Design, Manufacturing and Management Systems is involved in a variety of research and training activities. The following is an overview of the areas that research teams work in, with some faculty members participating in more than one research area. The descriptions that follow present many of the areas of expertise that the listed faculty has.

Dimensional metrology methods are used to evaluate parts and tooling for precision, accuracy, surface finish, capability, and tolerance modeling. The ATOS II high-resolution digital scanning system allows precise volumetric scanning for dimensional verification. Training is offered in part and process verification through the application of quality management systems and ISO 9000.

Metrology is the science of measurement. A metrologist is a person who practices one or more of the methods employed in measurement. All measurements are relative in that they are comparisons of some known standard. Some ways to measure things are by weight, pressure, resistance, temperature, quantity, capacity, etc.
Metrology in the Department of Engineering Design, Manufacturing and Management Systems serves many majors which are related to manufacturing. In our modern industrial society, we need to be able to produce manufactured goods that are made to exacting standards, able to be repaired with interchangeable parts, and be consistent in their production so that costs can be reduced.
Although all arts of measurement are important, the course titled Dimensional Metrology, focuses on the dimensional characteristics of products. Students successfully completing this course will:
- Understand the purpose of critical dimensions in manufacturing.
- Understand the principles and operation of precision measurement tools and equipment used in modern manufacturing.
- Understand the fundamentals of inspection methods and systems.
- Analyze simple parts for dimensional accuracy and functionality.
- Measure the manufacturing process using deterministic metrology through statistical techniques.
- Design simple inspection gauge and checking fixtures.
- Design simple productive tooling that assures duplicate parts.

Used mainly by our manufacturing engineering technology students, the fabrication lab provides individuals with hands-on experience about materials and processes used in fabrication, and it is used to show students how and when to apply these materials and processes in an industrial environment.
Fabrication has to do with studying and applying ways to form and connect materials in order to create a whole product. The process is one of the most important in the manufacturing of consumer products. For instance, what would modern society do without the likes of automobiles, ships, bulldozers and washing machines? All are examples of fabricated items. In fact even the building that houses our fabrication lab is an example of fabrication.
Therefore, students may learn how to form materials such as sheet metal and angle iron, (such as an "I" beam) in order to integrate them into the final product. This task might include one or more of the following processes: press working, shearing, bending, flame cutting, welding and fastening methods including adhesives.
Students may also be exposed to the post-fabrication methods of plating, coating, and painting for the aesthetic and protective improvement of a part or product.
Machining is a process where parts receive their final size and shape by the removal of chips using a shaped cutting tool. Traditional methods include sawing, turning on a lathe, milling, abrasive grinding, drilling and shaping machines. Modern methods use electrical discharge, abrasive water jet and lasers instead of a shaped cutting tool.
Students learn how to set up and operate these machines in order to productively and economically produce consumer products. They understand jig and fixture design, cutting tool choices, material machine ability, cutting speed and feed rates and can calculate machine time and cost estimates.
High performance cast metal design uses the four major solidification software packages, advancement of non-traditional casting processes, and thermal distortion testing of a variety of bonded mold materials.

Western 九一麻豆制片厂 University offers a superlative student-centered metal casting experience in an environment that is unparalleled by other colleges. The goal is to see students applying practical concepts that will prepare them for a future in the manufacturing industry. To achieve this our lab is equipped with machinery, tooling, hardware, and software to help students design, produce and test a wide range of cast metals and cast metal matrix composites.
Our facilities and equipment allow students to understand the following melting, molding and casting processes, which are related to many facets of engineering: green sand mulling, green sand molding, shell molding, investment casting (wax press, tooling and cure furnace), gas and crucible melting, no-bake core melting, evaporative pattern casting and grinding and finishing.
This lab allows for the custom formulations of alloys. Students and faculty use the following software programs to analyze these alloys, minimizing problems in casting defects and maximizing aesthetic qualities.
- Gating design
- Risering systems
- Finite element analysis
- Solidification analysis
A metal casting short course sponsored by local chapters of the American Foundry Society is held at WMU each June. During a week-long stay, students work with a professor and senior CEAS students to mold, melt and pour.
The full service metallography lab, located in room G-108, mainly functions to support teaching and research related to metallic materials. This lab contains the following equipment:
- Stereomicroscope with digital image capture
- Metallurgical microscope with digital image capture
- Electrolytic etching equipment
- Rockwell hardness tester (A, B, and C scales)
- Brinell hardness indenter and measurement systems
