CNC
Machine: Advantages, Disadvantages and Applications.
The CNC machine works based on CAD and CAM programs
and computer control. CAD (Computer-Aided Design) is drawing software. Also,
CAD software is used to increase the productivity of the designer, improve the
quality of design, improve communications through documentation, and to create
a database for manufacturing. Whereas, CAM (Computer-Aided Manufacturing)
having two codes like G-code and M-codes on which all the programs are written
and feed into the machine to perform the various operations. (i.e. turning,
grooving operation in a lathe).
Advantages
of CNC Machine:
Following are the advantages of having a CNC machine:
- ·
The
CNC Machine provides a workpiece with better precision and accuracy.
- ·
Fewer
workers required which helps to saves the labor cost.
- ·
A
high skilled operator not required. Even a trained worker can operate these CNC
machines.
- ·
CNC
Machine can produce complex designs with high accuracy in minimum possible
time.
- ·
CNC
machine has an online editing program, which means any changes and mistakes in
cutting conditions or in dimension can easily be edited and modified by the
part data store in the computer without sending the tape for re-processing.
- ·
The
conversion of the unit can easily be done by this machine (SI to British or from
British to SI).
- ·
It
can diagnostic its own fault easily, there is a special software enables easy
to troubleshoot if the CNC system fails to operate and also having the
capability to assist in maintaining and repair the system automatically.
- ·
It
also helps with safety reasons.
- ·
Low
Maintenace required
- ·
Reduce
setup-change over time.
- ·
The
CNC Machine has Higher Production and capability.
- ·
It
can run for 24 hours a day.
- ·
Reliable.
Disadvantages
of CNC Machine:
·
Here
are some disadvantages of CNC machine:
- ·
The
installation cost is high.
- ·
Even
do the parts of the CNC machine are high.
- ·
When
any failure occurs in the machine the high skilled profession requires to solve
the issue.
- ·
Computer
knowledge is required.
- ·
Program
knowledge is required
Applications
of CNC Machine:
These are some applications of CNC Machine:
- ·
The
main application of the CNC machine is to remove metal at a faster rate as
compared to a traditional machine-like lathe, milling machine.
- ·
This
is also used in fabrication industries.
- ·
This
machine is used for automatic removal of metal from the workpiece wherein
another machine like lathe, Milling the metal remove is done manually.
