13. Design for manufacture and Project Management

Question 1

What is quality control?

Answer 1

Monitoring, checking and testing procedures used throughout production

Question 2

What is quality assurance?

Answer 2

Procedures and policies which enusre that products meet specifications criteria.

Question 3

What are some examples of quality assurance procedured and policies?

Answer 3

• Checking correct temperature
• cutter maintenance shedules
• pre productions CAD modelling
• FEA
• CFD
• Mould flow analyis

Question 4

What is total quality management (TQM)?
(PMS)

Answer 4

A system to improve QA by harnessing workforce expertise.
- reduce waste, make products right the first time.
- workforce views feedback and communcations are highly prioritised.

Question 5

What is scrum?
(PMS)

Answer 5

Use of workforce teams to respond quickly to product desing and manufacture.
- Main focus is to work in a team to reach goals in a short timescale.
- Teams goals are specifies and fedback progress at daily update meetings - responding to issues

Question 6

What is a Project Management System?

Answer 6

Systems to improve effienciency and reduce waste.

Question 7

What is the six sigma
(PMS)

Answer 7

System for process improvement to reduce defects to fewer than 3.4 in every million
- Procedure monitors , assessed and improved each stage of desing and manufacture.
DMAIC

Question 8

What are the 5 key stages of the six sigma?
(PMS)

Answer 8

D efine the issure requiring improvement
Measure the extent of the issue
Analyse where the measured issue occur
Improve by intorducing rectifications procedures
Control the modified procedures through effective QA

Question 9

What is Critical Path Analysis?

Answer 9

Analysis of stages in a project to ensure time efficient completion.
- unnecessary waiting times can be identified
- Parallel processing oppurtunites can be exploited for max efficinecy.

Question 10

What are some quality control techniques?

Answer 10

Monitoring, checking and testing
Tolerance
Digital measuring devices

Question 11

What are specific Quality control methods?

Answer 11

go/no go gauge
Laser or probe scnning
Digital measuring devices
NDT

Question 12

What is the Go/No go gauge

Answer 12

• These check single measurement for tolerance range with pass or fail reading
• Made with minimum and maximum dimensions so it is easy to read
• quicker than vernier
• no need for adjustments

Question 13

How do Laser ot Probe scanning and measuring work?

Answer 13

• Co ordinate Measuring Machinery can be used
• Highly accurate
• CMM checks tooling accuracy
• can scan thousand of reading per second.
