Q

programable automation >> definition of Numericaly controled Machines (NC)

A

Machines that perform operations by following mathematical processing instructions

19
Q

Programable automation >> definition of Computerized Numerical Control (CNC)

A

Individual numericaly controled machines have their own computers

20
Q

Programable automation >> Definition of Direct Numerical Control (DNC)

A

One computer controles a number of numericaly controled machines

21
Q

What are the caracteristics and tools of Flexible automation

A
  • Premits continuous variation and product variety
  • customized equipment
  • Machine Center
  • Flexible manufacturing system
  • Computer integrated manufacturing
22
Q

Flexible Automation >> define Machine center

A

A machine capable of performing a variety of operations on parts

23
Q

Flexible Automation >> define flexible manufacturing system

A

group of machining centres, controlled by a computer, with automatic material handling and robots or other automated equipment. They can produce a variety of similar products

24
Q

Flexible automation >> define Computer integrated manufacturing (CIM)

A

A system that uses an integrating computer system to link a broad range of manufacturing and other activities, including engineering design and production planning and control. More encompassing CIM systems can link order taking, scheduling, purchasing, inventory control, shop control, and distribution to manufacturing. In effect, a CIM system integrates information from other areas of an organization with manufacturing.

25
Q

definition of Process design

A

Identifying the activities, resources, and controles needed in the production process

26
Q

  • Office layout
33
Q

definition of Layout

A

Refers to the location of departments, work centres, or equipment in the facility/plant

34
Q

Product (line) Layout

A
