Everyone in this class is an “A” student until you prove yourself otherwise.

Why do you need to take this course?

A company must produce products in an optimal way to compete in today’s global marketplace.

Why do you need to take this course? A knowledge of the basic manufacturing processes is essential for a successful engineer in today’s global marketplace.

What do engineers do? Design Products Manufacture Products Manage Departments and Companies Research

Course Objectives Students should understand of the principles of the major manufacturing processes Students should be able to recognize the standard processes used to produce products Students should be able to select the optimal process to produce a product

Manufacturing processes alter a material’s properties in a controlled manner to produce components of products. What is a manufacturing process?

Types of Processes 1.Material removal 2. Deform or shape material through heat or pressure 3. Join two or more materials

Remove Material 1.Sawing 2.Drilling 3.Milling 4.Turning (Lathe) 5.Abrasive finishing

Deform/Shape Material 1.Casting 2.Rolling/Forging 3.Extrusion/Drawing 4.Sheet metal forming 5.Powder metal processes

Join Two or More Materials 1.Welding 2.Brazing 3.Soldering 4.Adhesive bonding 5.Fastening

Math/Manufacturing In calculus there is usually only one correct answer to a problem. In manufacturing there are usually many ways to make a part, some ways are better than others

Manufacturing A company must produce products in an optimal way to compete in today’s global marketplace. On all tests and quiz questions you are expected to give an optimal answer to a question, not just an answer that will work.

Example How can you sharpen a wooden pencil?

Example Knife or other sharp object Sand or abrasion Toy pencil sharpener Hand pencil sharpener Electric pencil sharpener Automated pencil sharpener How can you sharpen a wooden pencil?

Example You are taking a timed test Situation You are designing a department office You are in your dorm room You have 500,000 pencils that are to be packaged with a crossword puzzle
