Slide 1: Materials Science and Manufacturing Process
Manufacturing - Technologically
Application of physical and chemical processes to alter the geometry. properties, and/or appearance of a starting material to make parts or products
Manufacturing as a technical process
Starting material → Manufacturing Process → Processed Part or Scrap and Waste
Manufacturing process
Machinery, Tooling, Power, and Labor
Manufacturing - Economical
Starting Material → Material in Processing (value added) → Processed Part
Manufacturing Capability
Consists of processes, people, and systems designed to transform a certain limited range of materials into products of increased value
Three building blocks of modern manufacturing
Materials, Processes, and Systems
Manufacturing capability includes:
Technological processing capability
Physical product limitation
Production capacity
Three generic perspectives on How New Products Are Made
Business Development Perspective
Company Perspective
Product Development Perspective
Solidification Processes
Starting work part is shaped by application of forces that exceed the yield strength of the material
Ex. Forging and Extrusion
Deformation Processes
Starting material is heated sufficiently to transform it into a liquid or highly plastic state
Ex. Metal Casting and Plastic Molding
Material Removal Processes
Excess material removed from the starting piece so what remains is the desired geometry
Ex. Machining: Turning, drilling, and milling; Grinding and Nontraditional Processes
Manufacturing Engineering
Efficient use of Resources
Machinery, Tooling, Power, Labor
Quality
Excite Customers, Minimize Variation
