CNC Machine Tools
CNC (computer numerical control) machine tools are designed
for extremely precise removal of metal. They are operated by a computer
which calculates the desired path of the cutting mechanism, and then
translates that information into precise movements. If a change is desired
in the design, the new information can be easily fed into the computer.
CNC machine tools have revolutionized the fabrication industry. Many
complex shapes and curves can be easily manufactured using these devices.
As the technology improves, these machines are becoming more capable
of creating even more complex designs.
Because most CNC machine tools are expensive, they are rarely found
in home workshops. These machines are primarily designed for heavy industrial
applications. Several of these devices can be linked together to create
components that require several operations before they are completed.
