Introduction
Manufacturing System plays very important role in daily
manufacturing operation. The objective is to have efficient control
of the organizational structure in order to produce high quality
products at lower prices within a shorter period of time.
Companies that having a good manufacturing system normallycan execute their operation very well as they become more
productive and to make more efficient use of resources.
Manufacturing information systems, material handling,
computer-integrated manufacturing (CIM), and production planningcontrol are just some of the areas that have help companies
improving their understanding and awareness in the manufacturing
and service sectors in order to stand in the very competitive
industry.

Component in Manufacturing System
Manufacturing system can be elaborated as system whichhaving the combination of integrated equipments and humanresource, whose give a guideline for material processing.
A Manufacturing system consist of several components, whichcan be listed as below;
Production Machines
Material Handling System
A integrated computer system to control components
Human Resource/ worker to operate and manage the system

Production Machines
In any manufacturing systems, almost all the operation orassembly work was help by the machines or with the aid of thetools.
All this machine will be help to achieve high productivity andalso shortercycle time.
There are many type of production machine and thiscombination of production machine in one production floor canbe called as a workstation.
There are 3 type of production machines as below and all thiswas based on the complexity and how advance the tool:
Manually operated
Semi-automated Fully automated

Manually Operated Machine
Manually operated machines are controlled/operatedorsupervisedby worker/operator(human resource).
This manually operated machines provides thepowerforoperation and the worker provides the control.
Some example of the machine that fall into this category was aconventionalmachine that was normally found in small andmedium industry such as milling machine and drill pressesmachine.
All this type of machine need the worker to operate is as thismachine do not have any program to control or to perform thetask.
In a modern age factory some example of this type of machinesuch as metrology, where this machine will help to ease the jobbut need an operator to operate the machine.

The operator must be at the machines continuously to engagethe feed, position the tool, load and unload work parts andperform other task related to the operation.

Semi Automated Machine
Semiautomated machines can perform a task without anyoperator attend to the tool. By using software/hardware control
machine able to operate without any assistant for one cycle of
task.
An example of machine that fit into this category is CNC
machine orotherprogrammable production machine that underthe tool control for one work cycle. But this type of machine
requires a operator to unload the finished part and load the next
part at the end or beginning of each cycle.
In these cases, the worker must attend to the machine every
cycle but doesnt need to be continuously present during thecycle.

Semi Automated Machine
With this, one operator can attend/operate more than onemachine at one time as only extra time required for each
machine to make sure it continuously running with high
productivity.

Fully Automated Machine
Fully automatedmachines was a machines that capable tooperate automatically with no human attention forperiods of
time that are longer than one work cycle.
Although a worker attention is not required during each cycle,
some form of machine tending may be needed periodically
Time to time operator might be need to attend the toolperiodically to add in new material.Also some error on the
machine that require operator to solve the error before tool can
start running again.
Normally this type of machine will be link withAMHSsystem
too.

Most of the advance or high tech factory will have this type ofmachine. This type of machine will help to reduce cycle time andalso to reduce labor cost.
This fully automated machine also can reduce the number ofproduct scrap or reject due to less human involvement in the cycletime.

Workstation
Combination of machines in one workplace are normally call asworkstation.
In this workstation, some specific task or operation was
performed with combination of this 3 type of machines.
A complete manufacturing system may consist of one or more
workstations. A manufacturing system, with multiple workstation is called
production line, assembly line, machine cellor other name
depending on its configuration and function.

Material Handling System
Material Handling System can be defined as an aspect ofmaterials management relating specifically to the physicaltransfer of materials.
The movement of materials (raw materials, scrap, semi-finishedand finished) to, through and from productive processes; inwarehouses and storage; and in receiving and shipping areas
The work machines which normally semi- automated or fullyautomated machines are connected by a material handlingsystem to optimize parts flow and the central control computerwhich controls material movements and machine flow.
Normally the machines can be segregate to 3 parts; loading
unit, positioning unit & unloading unit. Anyhow, transporting work unit between machines to machines
(stations to stations) is also required

Computer is required to control the automated and semi automated equipment and to participate in the overall
coordination and management of the manufacturing system.
Even in manually computer system is useful to supportproduction, such as a completely manually assembly line.
Computer Control System

Computer control system divide into:ii. Communicate instructions to workers
communicate to the operator by given complete
instructions. Download part programs to computer
send instructions to computer controlled. i.e CNC machinetools
iv. Material handling system control. Controlling the material handling system to the coordinate
at the workstations.
v. Schedule production accomplished at the site of the manufacturing system.
Computer Control System

i. Failure diagnosis diagnosis equipment malfunctions, preparing preventive
maintenance schedule and maintaining spare parts
inventory.
ii. Safety monitoring to ensure that the system operate in the safe mode and at
the same time to protect workers and the equipment in the
system.
iii. Quality control Functions to detect any possibility reject product from the
production line.
iv.Operations management managing all manufacturing operations whether direct or
indirect.

Human Resources
Humans refers to allpersonnel, operators, vendors, customersetc.
To operate and manage the system/process
Required eitherfulltime orperiodicallyto keep the system
running
System manufacturingis value added system to produce partsand products
In contextofmanufacturing system, humanperform some or allof the value addedworkthat is accomplishedon theparts/products.

Human Resources
Performing eithermanual(direct) work on it or by controllingthemachines.
In fully automated machine, direct labour is still needed. For example : loading or unloading parts, changing tools,
resharpening tools etc.
In Automated Manufacturing System, workers also are needed
to support the system.
For example : computer programmers/operators, maintenance and
repair.

Personnelrelated issues include what is the capability levelofavailable labor, working culture (one shift or two shift), how
many workers need to hire, what is the level of training needed,
whatpolicies to drive a good working environment.
As a conclusion Manufacturing system need all these fourcomponent to make up the system (running the system).
Each component plays an important role in manufacturing
system. If either one of the components is not included, this
systems is not call a manufacturing system.

Example of factory that using combination of 4
components of Manufacturing System
With the combination of this 4 manufacturing system components willhelp to improve company competitiveness in the global market.This is essential for company to have good system for in each
components so that the company can satisfy the customer need and keep
growing.
