Competitive Manufacturing Flashcards
Considerations for product design
Simplicity
Performance
Environmental impact
Possibility for future growth/changes
Necessary precision
Accessibility
Possibility for maintenance
Safety
Commercial availability of components
Characteristics of a high quality product
Reliable
Safe
Inexpensive
Upgradable
Robust
Accessible
Return on quality (ROQ)
Quality is viewed as an investment
More expensive upfront but pays for itself in the long run
Total quality management (TQM)
Defect prevention is better than defect detection
Quality should be improved/maintained at all manufacturing stages
Taguchi method
Design and manufacturing optimized for quality and cost by combining engineering and statistics
Deviation from design objective is a loss in quality which in turn is a financial loss
QS 9000
Developed for automotive industry to standardize supplier quality
ISO 14000
Concerned with affects of processes/products on environment
ISO 9000
Certifies processes (not products) through periodic audits of manufacturing facilities
Life-cycle assessment factors
Material input and output
Energy input and output
Environmental impact and burden
Designing for recycling involves
Modular design
Less material overall
Avoiding non-recyclable coatings
Not mixing materials
Recyclable materials
Avoiding permanent joining
Automation can improve
Efficiency
Precision
Integration
Cost reduction
Consistency
Hard automation
Modular machines designed for very specific purposes
Only financially feasible for large production runs
Soft automation
Flexible machines that can be configured for many different applications
Industrial robot movement classifications
Cartesian
Cylindrical
Spherical
Articulated
Fixed/variable-sequence robot
Follows a set sequence of movements
