Numerical Control
- Numerical Control (NC) is a technique permitting automatic
operation of a machine or process through a series of numbers, letters,
and various other symbols. NC technology is widely used throughout the
manufacturing industry and is currently used in a large variety of applications
and processes. A major contribution of NC technology to industry lies within
the ability to change the way in which machining processes can be automated.
Advantages of such automation include ease of adaptation and adjustment
to vastly different production situations. By using NC programming and
machining, the risk of human error is reduced along with the dependence
on highly skilled operators. Through the combination of computer technology,
NC technology, and computer aided manufacturing (CAM), the basis for realizing
unmanned automation of manufacturing systems and processes are made possible.
- A requirement of the group project is to understand and
utilize the fundamentals of NC programming. For example, the Nissan symbol
(Figure 1) enabled the team to learn the basic operation of a numerically
controlled machine. In order to learn how to generate an NC program for
a designed part, two parts were developed using CADKEY. Cutting Edge software
was used to generate the tool path required to manufacture the parts at
the machining center. To create the Nissan symbol, the tool path or ÒGÓ
code was generated by typing in the commands for tool selections, feedrates,
speed rates, coolant, travel commands, etc. Consequently, in order to remain
competitive in todayÕs manufacturing industry and surpass the needs
of the customer, more efficient computer software is required for the integration
process.
