Why to study mechanical shaping Mechanical shaping is important economically Mechanical shaping (manufacturing) is important historically Historically, the importance of manufacturing (mechanical shaping) in the development of civilization is usually underestimated Throughout history, human cultures that were better at making things were more successful Making better tools meant better crafts & weapons � � Better crafts allowed the people to live better Better weapons allowed them to conquer other cultures in times of conflict

Manufacturing process Two ways to define manufacturing: a) as a technical process, and b) as an economic process So, a manufacturing plant consists of a set of processes and systems (and, of course, people) designed to transform a certain limited range of materials into products of increased value.

Classes of Materials

MET 206 – Fundamentals of Mechanical Shaping MET 206

Solidification Processes Casting and molding processes start with a work material heated to a fluid or semifluid state. The process consists of: (1) pouring the fluid into a mold cavity and (2) allowing the fluid to solidify, after which the solid part is removed from the mold. Not in this course

Deformation Processes

Material Removal Processes

Particulate Processing Particulate processing: (1) the starting material is powder; the usual process consists of (2) pressing and (3) sintering.

Waste in Shaping Processes

Surface Processing (1) cleaning (2) surface treatments (3) coating and thin film deposition processes. Not in this course
