Q

What is the difference between liner and iterative design

A

Instead if leading straight into manufacturing a model or prototype is made and tested first
After testing, the evaluation stage generates suggestions for improvements

Q

What is an advantage of iterative design

A

It enables and encourages a culture of continuous improvement , which leads to better products and higher sales
The product will motion the clients briefer closer

Q

What is an disadvantage of iterative design

Study These Flashcards
A

Has potential for scope creep
Inconsistent planning

21
Q

What is ment by anthropometric data

Study These Flashcards
A

Research-based data that provides guidance on typical measurements for different parts of the body

22
Q

What is meant by design for manufacture

Study These Flashcards
A

Design approach that ensures products incorporate features that support the use of a particular process in their manufacture

23
Q

What is an example of a design manufacture approach

Study These Flashcards
A

Using a draft angle an injection-moulded components to allow them to be easily released

24
Q

What is the purpose of testing

Study These Flashcards
A

To ensure that a design elements have fully fulfilled the client brief and PDS. Also to ensure it is suitable, effective and safe

25
What is ment by commissioning
Process of getting a newly installed machine or piece of equipment up and running. Ready for handover to the customer
26
What is effective maintance
Maximise the service life of machinery and equipment so that it lasts longer and needs to be replaced less frequently
27
Reactive maintance
Addressing equipment issues as they arise. Is used when a machine has broken down. Is best used for assets that have low repair costs and aren’t immediately essential to success of operations
28
What is an advantage of reactive maintenance
Low initial maintenance costs No unnecessary maintance Simplicity and flexibility
29
What is an disadvantage of reactive maintance
Increased unplanned downtime Delays sourcing spare parts Risk to worker saftey
30
What is planned maintance
This is scheduled, proactive activities armed at maintaining, repairing, or upgrading systems, equipment, or infrastructure. Typically used in situations where an organisation wants to proactively maintain or improve its system
31
What is an advantage of planned maintenance
Reduces downtime Cost savings Increased equipment lifespan Improved performance and efficiency
32
What is a disadvantage of planned maintance
High upfront costs Unnecessary maintenance Can be hard to perform maintenance in optimal time
33
What is preventive maintance
The act of performing regularly scheduled maintance activities to help prevent unexpected failures in the future
34
What is an advantage of preventive maintance
Reduces unexpected downtime Can help identify and dress potential issues early
35
What is an disadvantage of preventive maintance
It can be costly and time consuming Can lead to over maintance Result in unnecessary costs and waste
36
What is condition based manufacturing
Maintance that involves performing maintenance tasks only when monitoring indicates the equipment is showing signs of wear or potential failure
37
What is an advantage of condition based maintance
It optimises resource unitilization and reduce costs
38
What is an disadvantage of condition based maintenance
It requires significant upfront investment in monitoring technologies and systems
39
What are machine operators
People who are responsible for the day to day operation of machines and equipment
40
What are maintenance engineers
People who conduct the maintance and repair tasks required by planned maintenance schedules or in response to breakdowns
41
What are maintance managers
People who are responsible for planning and organising maintance activities and for making sure unplanned maintenance is minimized
42
What is an environmental influence on maintence
Minimising emissions and preventing leaks of oils, hydraulic fluids or other chemicals
43
What is function layout
Similar equipment and skilled workers are arranged into workstations based on process types
44
What are the advantages of functional layout
It’s a flexible system, that uses little automation, it works well in batch production wear there is high degree of variation
45
What are the disadvantages of a functional layout
Works in progress spends a lot of time being moved between workstations and waiting to be processed Highly skilled workers required drive up costs compared to other layouts.
46
What is cellular layout
Self-contained manufacturing cells for batch porduction of variants within a family of similar components or products
47
What are the advantages of cellular layout
Arranged in a horseshoe shape to enable workers to move quickly and easily to compete multiple tasks Maintance flexibility by using highly trained workers who are familler with he product Changeover is quick and easy
48
What are the disadvantages of cellular layout
Prone to production bottlenecks in case of machinery breakdown Errors int he setup can lead to a loss of effiency The setup time can be long since moving machinery and training take time
