1

What is manufacturing?

Turning raw material into an end product

2

What is technology?

A piece of equipment

3

What are systems?

A group of resources

4

What are the 3 features of technology?

Operating capability - e.g. how large a product
Operating parameters - e.g. how fast cutter goes
Operating costs - e.g. how much energy consumed

5

What are the manufacturing system demands?

Increased product variety
Decreased product quantities
Increase in customer expectations
Decrease in time to market
Use new or better materials
Facilitate global production

6

What are physical structures?

Factories, equipment etc

7

What are virtual structures?

Management and control systems

8

What are the 5 P's of product and operation management?

Product
Plant
Process
Programme
People

9

What is the Product?

The interface between marketing and production
An agreement must be reached on performance and aesthetics, quality and reliability, quantity, selling price/production cost and delivery date/lead time

10

What is the Plant and what must it do?

Provides the tools to manufacture the product
It must match all needs and continue to do so
Must consider possible future demands, layout of buildings and facilities, performance and reliability of equipment, maintenance, safety and social responsibility

11

What is the Process?

The combination of people, skills, and equipment to manufacture the product
To optimise consider available capacity and skills, form of production, plant layout, safety and maintenance, costs

12

What is Programme/Resource Plan?

System which organises and controls the production operations.
Generates timetables and procedures for purchasing, production, maintenance, cash flow, storage and transport

13

What is People?

Link the virtual and physical structures

14

What is High Value Manufacturing (HVM)?

As the UK cannot compete on volume manufacturing, they try to compete by adding value to manufactured goods through technological improvement

15

What are the 3 key demands on HVM?

Reduced product quantities
Increased customer expectations
Use of new or better materials

16

How does HVM generate jobs?

It requires new processes to be developed and enables supply chains to be brought closer to production facilities

17

What is Industry 4.0?

Applying emerging digital technologies to manufacturing in order to improve productivity and quality and reduce costs

18

Who will industry 4.0 impact?

Basic manufacturing processes

19

What is Machining?

The process of removing unwanted material from a workpiece in the form of chips

20

What are examples of traditional casting?

Disposable mould casting such as sand or investment casting

21

What are examples of recent casting developments?

Permanent mould casting, powder metallurgy, additive manufacturing

22

What are examples of traditional machining?

Turning, milling, drilling, boring, sawing, grinding, polishing

23

What are examples of recent machining developments?

High speed machining, grinding, electrical discharge machining

24

What are examples of traditional joining?

Fusion welding, brazing, soldering, mechanical fastening

25

What are examples of recent joining developments?

Electron/ laser beam fusion welding, resistance/spot welding, solid state

26

What are examples of machining inputs?

Machine tool, cutting tool, workpiece properties, cutting parameters, workpiece holding device

27

What are machine tools?

Manual lathes and milling machines

28

What are cutting tools?

Consumables required for machine tools

29

What are one-piece cutting tools?

Traditional solid cutting tools

30

What are modern two-piece cutting tools made of and why is this beneficial?

Made of an insert and a body, allowing each part to have different properties and use more exotic materials. Also cheaper as only warn parts need replacing.
