Chapter 1 - Introduction to Manufacturing Processes
Cards in this deck (18)
- 1Characteristics changed by manufacturing processes (5)State, geometry, microstructure, properties, and appearance
- 2Starting material can be (3)ingots, billets, or semi-finished products
- 3Primary goal of manufacturing processesproduce components of a selected material at the lowest possible cost with the required geometrical shape and optimum properties for the proposed service environment
- 4Lowest cost implies (5)Fewest number of steps with little or no secondary processing.
Making a component as close as possible to the final product shape and size.
Using high recovery processes resulting in fewer scraps and limited material handling.
Use of less expensive starting material.
Using environmentally friendly processes. - 5Manufacturing/production systemA collection of operations and processes used to obtain desired products, parts, or components
- 6Bases for classification of manufacturing processes (4)The state of completion of the product.
The effect of processing operation on the properties of the initial material.
Effect of the processing on the surface of the component.
Initial state of the raw material. - 7Conversion processesInvolve the transformation of materials from their raw, natural, or initial state to a more useful semi-finished form (extraction, and casting and molding processes)
- 8Processing operationsManufacturing processes that can be used to transform a work material from one state of completion to a more advanced state that is closer to the desired product. (shaping operations, property-enhancing operations, and surface processing operations)
- 9Controlled application of energyUsed to alter a work part's shape, physical and mechanical properties, and/or appearance (thermal, mechanical, electrical, and chemical).
- 10Shaping operationsAlter the geometry, and in some cases, physical and mechanical properties (solidification, deformation, particulate, material removal)
- 11Property-enhancing operationsUsed to manipulate or enhance both the physical and mechanical properties of the starting solid semi-finished material or product (heat treatment and deformation processes).
- 12Surface processing operationsOperations performed to clean, treat, coat, or deposit material onto the exterior surface of the work part (electroplating, nitriding, and case hardening).
- 13Assembly operationsInvolve the uniting of two or more separate parts to form a new entity (joining processes, and mechanical assembly).
- 14Joining processesInvolves the uniting of individual workpieces permanently or semi-permanently to form subassemblies by melting, use of adhesive bonding materials, and/or filling and impregnating workpieces. Most joining processes are based on the addition of weight (welding, brazing, soldering, adhesive bonding, and solid-state bonding).
- 15Mechanical assemblyInvolves the uniting of assemblies without melting (semi-permanent assemblies using: nuts, bolts, screws, and other threaded fasteners; permanent assemblies like: press-fitting and expansion fits).
- 16Primary manufacturing processesConversion of the natural raw materials into unfisinished engineering materials.
- 17Secondary manufacturing processesConversion of the products from the primary manufacturing operations into semi-finished or finished products or parts.
- 18Additive manufacturingProduction of a functional engineering component built one layer at a time from CAD data (3D printing and rapid prototyping).
