Course Objectives:
Students who complete this course will reach the following objectives:
- An understanding of the relationship between product design decisions and cost
|
- An understanding of the economics of assembly and manufacturing processes
|
- An understanding of the relationships between material and process selection
|
- An appreciation of the importance of product design in the context of global competitiveness
|
- An appreciation of the relationships between design decisions and manufacturing defect rates
|
- An understanding of the importance of team working in product development
|
Topics:
-
Analysis of products for ease of manual assembly and the establishment of an assembly efficiency rating. Project involving redesign of a small product and estimation of reductions in assembly time and cost.
-
Product design considerations for assembly automation. Special considerations of part design for automatic presentation in automatic assembly systems.
-
Consideration of the major importance of the initial choice of materials and processes in product design. Relationship between material selection and process capabilities. Comparison of performance and cost of alternative classes of materials.
-
Design for individual manufacturing processes and assessment of tooling costs. Investigation of procedures to identify the number of cavities or processing steps at the early design stage. Consideration of the effects of design decisions on material, tool and processing costs. Case studies involving redesign of components or selection of alternate materials to reduce machine size requirements, processing times and mold or die costs. A selection of material and process combinations will be covered.
-
Consideration of the effect of product design on manufacturing quality and defect rates. Particular attention will be paid to assembly quality issues.
