week 1 Flashcards
what is Manufacturing technological
the application of physical and chemical processes to alter the geometry, properties, and/or appearance of a given starting material to make parts or products. Also includes assemble of multiple parts.
what is Manufacturing economical
The transformation of materials into items of greater value by means of one or more processing and/or assembly operations
what is a Primary industry
cultivate and exploit natural resources (e.g., agriculture and mining)
what is a Secondary industries
take the output of the primary industries and convert them into consumer and capital goods (e.g., manufacturing, construction, power utilities)
what is a Tertiary industries
constitute the service sector (e.g., retail, financial, education, transportation, government)
what are Consumer goods
products purchased directly by consumers (e.g., cars, personal computers, TVs, tires, and tennis rackets)
what are Capital goods
products purchased by companies to produce goods and/or provide services (e.g., aircraft, trucks and buses, machine tools, construction equipment)
what are Processing operations
transforms a work material from one state of completion to a more advanced state that is closer to the final desired product
what are Assembly operations
joins two or more components to create a new entity, called an assembly, subassembly, or other term (e.g., weldment)
what are shaping operations
alter the geometry of the starting work material
what are Property-enhancing operations
improve the physical properties of the material without changing its shape
what are Surface processing operations
performed to clean, treat, coat, or deposit material onto the surface of the work
what are Solidification Processes
Starting material is a heated liquid or semifluid that cools and solidifies to form the part geometry
what is Particulate Processes
Starting material is a powder, and the powders are formed to create geometry and heated to strengthen
what are Deformation Processes
Starting material is a ductile solid (commonly metal) that is deformed to shape the part
