MANUAFACTURING SYSTEM

The manufacturing system is a collection of

integrated equipment and human resources that

perform processing and assembly operations on

work material.

COMPUTER INTEGRATED MANUFACTURING

An computer integrated system requires that there be two or more computers connected to pass information.

Following three components distinguish CIM

from other manufacturing methodologies;

Means of data storage, retrieval, manipulation

and presentation;

Mechanisms for sensing state and modifying

processes;

Algorithms for uniting the data processing

component with the sensor/ modification

component.

AUTOMATED MANUFACTURING SYSTEM

Automated manufacturing system reduce level of human participation compared with the corresponding manual process.

Example of automated manufacturing system includes

o Automated machine tools that process partso Automated assembly systemo Automatic material handling and storage.o Automatic inspection system.

NUMERICAL CONTROL (NC)

NC is a form of programmable automation in

which the mechanical actions of an equipment

are controlled by a program containing codes.

NC system consists of three basic components:

a) Part program,b) Machine Control Unit,c) Processing Equipment.

NUMERICAL CONTROL (NC)

The part program is the detailed set of commands to be followed by the processing equipment.

MCU is a microcomputer that stores and executes a program, by converting each command into actions by the processing equipment.

The processing equipment accomplishes the sequence of processing steps to transform the starting workpiece into a completed job.

INDUSTRIAL ROBOTICS

An industrial robot is a general-purpose programmable machine consisting of a mechanical manipulator and a controller to move it.

Robots can be used in a variety of scenarios; Hazardous Environments, Repetitive work cycle, Long production runs, Difficult work or tool handling.

PROGRAMMABLE LOGIC CONTROLLERS (PLC)

PLC is a widely used microcomputer based device that uses stored data instructions in programmable memory to implement logic, sequencing, timing, counting etc.

FLEXIBLE MANUFACTURING SYSTEM (FMS):

FMS is a highly automated machining center, consisting of a group of processing stations, interconnected by an automated material handling and storage system, and controlled by an integrated computer system.

An FMS is capable of processing a variety of different part styles simultaneously under NC control at different workstations.

GROUP TECHNOLOGY :

It is a method of manufacturing, in which similar parts are grouped together and manufactured together because of their similarities in design and production.

Cellular manufacturing is a concept in group technology, in which machine cells are developed where similar processes takes place.
