Manufacturing Systems Flashcards
What is advanced manufacturing technology?
- Impact of computers on manufacturing
- Impacts manufacturing management with integration of product development and manufacturing stages through ICT
Give 4 examples of advanced manufacturing systems
- Computer aided design (CAD)
- Computer aided manufacture (CAM)
- Computer integrated manufacture (CIM)
- Robotics
What is quick response manufacturing?
Developed to give companies a competitive advantage by increasing their operating efficiency
What does quick response manufacturing entail?
Manufacturer to move from batch production to flow production, triggered by consumer demand not demand forecasts
Give 3 examples of quick response manufacturing
- Total quality management
- Just in time
- Manufacturing cells
Give 4 advantages of quick response manufacturing
- Lower working capital required as raw materials and finished goods stock are minimised
- Better position to increase market share as quicker response times attract new clients
- Increased turnover of stock as production systems are triggered by demand
- Reduce the cost of quality by minimising waste
Give 4 disadvantages of quick response manufacturing
- Increased reliance on suppliers to react to demand
- Large variations in demand
- Managing and implementing changes can be difficult as QRM changes roles of employees, causing friction
- Manufacturer must have representation and backing from all disciplines to implement QRM
What is concurrent manufacturing?
Provides a systematic approach to integration of design, manufacture and related processes where all life cycle stages are considered at once
What is the main advantage of concurrent manufacturing systems?
Produces designs ‘right first time’ through the use of multi-disciplinary design teams, reducing development times enabling earlier release
What is quality function deployment?
Early in development, designers use QFD as a way of remaining ‘in touch’ with customer requirements to create a more successful product
What are the main features of quality function development?
- Focus on customer requirements
- Use of multi-disciplinary teamwork
- Comprehensive (House of Quality) matrix
Give 5 advantages of using quality function deployment as part of a concurrent manufacturing system
- Reduced time to market
- Reduction in design modifications
- Decreased design and manufacturing costs
- Improved product quality
- Enhanced customer satisfaction
What are the 6 major components of the ‘House of Quality) matrix?
- Customer requirements (Structured list of requirements taken from market survey)
- Technical requirements (Structured set of relevant and measurable characteristics)
- Planning matrix (Illustrates customer perceptions observed in market survey)
- Interrelationship matrix (Explores strength of relationship between customer and technical requirements
- Technical correlation (Used to identify where technical requirements support or hinder each other in the design)
- Technical priorities (Quality targets against each technical specification point)
What is a flexible manufacturing system?
A form of flexible automation in which several machines are linked together by a material-handling system, which is controlled by a central computer
What are the 2 main features of a flexible manufacturing system?
- Machine flexibility (Systems ability to be changed to produce new product types and change the order of operations)
- Routing flexibility (Use multiple machines to perform same operation on a part, and absorb large-scale changes e.g. volume)
