17
Q

Benefits of control programs

A

Enables automation and intelligent products/systems which are labour-saving and time-saving

18
Q

Limitations of control programs

A

Skill needed to learn programming languages, cost of microprocessors, specialist software needed to update/modify programs

19
Q

What are CD-ROMs?

A

(Compact Disc Read-Only Memory) Pre-pressed optical compact discs that contains data. Computers can read it but cannot write to or erase it. A type of read-only memory (ROM). Largely superseded by solid state drives (SSDs), increased internet coverage/bandwidth and the move to online platforms/data storage.

20
Q

Benefits of CD-ROMs

A

Discs are more durable than magnetic tape, lightweight, portable, no moving parts, universal compatibility, cheap to produce.

21
Q

Limitations of CD-ROMs

A

Every time there is a new product or update, new CDs need to be produced and shipped. It’s more expensive and slower than downloading software and data from online platforms/cloud-based services.

22
Q

What is CAD?

A

(Computer aided design) The use computers in the design of products. Could be 2D or 3D. Could also involve virtual testing/analysis, simulations, renderings, animations…

23
Q

Benefits of CAD

A

Designers/clients/users are better able to visualise/communicate products. Products can be more fully and accurately defined. Problems are spotted earlier in the design process.

24
Q

Limitations of CAD

A

Cost of hardware and software, need for skilled operators and training

25
Q

What is CADD?

A

(Computer aided design and drafting )The use computers in the design of products. Could be 2D or 3D. Could also involve virtual testing/analysis, simulations, renderings, animations, specifically including the challenge of creating technical drawings

26
Q

Benefits of CADD

A

The use computers in the design of products. Could be 2D or 3D. Could also involve virtual testing/analysis, simulations, renderings, animations…

27
Q

Limitations of CADD

A

Cost of hardware and software, need for skilled operators and training

28
Q

What is CAM?

A

Computer Aided Manufacturing. The use computers in the manufacture of products.

29
Q

Benefits of CAM

A

24/7 365 operation, reduced labour costs, increased accuracy, increased throughput, safer for humans

30
Q

Limitations of CAM

A

Large capital investment needed, skilled programmer/operators required, machines can be less versatile than humans

31
Q

Benefits of CNC

A

24/7 365 operation, reduced labour costs, increased accuracy, increased throughput, safer for humans

32
Q

Limitations of CNC

A

Large capital investment needed, skilled programmer/operators required, machines can be less versatile than humans

33
Q

What is CNC?

A

(Computer Numerical control) The automated control of machine tools and 3D printers by means of a computer and coded/programmed instruction (see the machines below)

34
Q

What is CIM?

A

The integration of computers across the entire manufacturing process, from conception/design to production of the finished product

35
Q

Benefits of CIM

A

24/7 365 operation, reduced labour costs, increased accuracy, increased throughput, safer for humans, combined together

36
Q

Limitations of CIM

A

Huge challenges are posed in relation to the exchange of data, the technology infrastructure, the integration of equipment from different manufactures, the involvement of suppliers and clients and their own systems and needs.

37
Q

What is a 3D printer?

A

A machine which can make 3D solid objects from a digital file, usually by additive manufacturing (FDM), but also by stereolithography or Selective Laser Sintering (SLS). Also known as rapid prototyping. The movement of the head is controlled in X and Y by the CNC data. The bed moves incrementally in Z

38
Q

What us a laser cutter?

A

A CNC device in which a focussed high-powered source of light is used to cut materials by vaporisation. The movement of the head is controlled in X and Y by the CNC data

39
Q

What is a CNC router?

A

A machine which uses a rapidly rotating cutter to machine profiles in solid materials using data generated by a computer. The movement of the head is controlled in X, Y and Z by the CNC data

40
Q

What is a micro router?

A

As above but smaller and more portable as a result. Usually within a sealed cabinet for safety. Often using for drilling small holes in PCBs

41
Q

What is a CNC lathe?

A

An engineering (or wood) lathe which can be driven by CNC data, also with automatic tool changing and sometimes automatic loading/unloading of parts

42
Q

What is a CNC milling machine?

A

A milling machine which can be driven by CNC data, also with automatic tool changing and sometimes automatic loading/unloading of parts
