It looks at the terms for classifying forming processes and the characteristic values and basic laws of metal forming including flow stress, plastic strain, plastic flow under combined stresses, flow curves, average flow stress and energy considerations. This lecture is a necessary prerequisite to understand the more specific treatment of metal forming subjects such as forging, impact extrusion and sheet metal forming in the subsequent TALAT lectures 3401 to 3805.

A general background in production engineering and machine tools is assumed.

The lecture includes examples of aluminium forgings and covers classification of forms for die forgings, tolerances for aluminium forgings, design rules, dimensional precision of die forgings and designing for material flow and grain structure.

A general understanding of metallurgy and deformation processes is assumed.

This course introduces you to modern manufacturing with four areas of emphasis: manufacturing processes, equipment/control, systems, and design for manufacturing. The course exposes you to integration of engineering and management disciplines for determining manufacturing rate, cost, quality and flexibility. Topics include process physics, equipment design and automation/control, quality, design for manufacturing, industrial management, and systems design and operation.

Class objectives are: internalize the attributes along which the success or failure of a manufacturing process, machine, or system will be measured: quality, cost, rate and flexibility; provide exposure to a range of current industrial processes and practices used to manufacture products in high and low volumes; apply physics to understand the factors that control the rate of production and influence the quality, cost and flexibility of processes; understand the impact of manufacturing constraints on product design and process planning; apply an understanding of variation to the factors that control the production rate and influence the quality, cost and flexibility of processes and systems; understand the role of control in processes and systems, especially in view of the presence of noise (variation); and provide exposure to a range of manufacturing system constraints.

Physical metallurgy encompasses the relationships between the composition, structure, processing history and properties of metallic materials. The seminar from which these images are taken seminar introduces metallurgy in a particularly “physical” way. The students do blacksmithing, metal casting, machining, and welding, using both traditional and modern methods. The seminar meets once per week for an evening laboratory session, and once per week for discussion of issues in materials science and engineering that tie in to the laboratory work. Students begin by completing some specified projects and progress to designing and fabricating one forged and one cast piece.
