A Sneak-Peek at the World of CNC Machining
CNC machining can be defined as the manufacturing process which includes the use of computers for controlling machine tools. The machine tools in this process work as per the program prepared with coded alphanumeric data. Usually known as G-code, the CNC machining language controls essential features such as motions of the tool, feed rate, depth of cut, location, speeds and functions of turning spindle or coolant on and off.
Components of CNC Machining
A CNC system usually comprises three basic components which are
- Part program
- Machine Control Unit
- Machine tool
Applications of CNC Machining
CNC machining is used for both for machine tools and non-machine tools. It is often used for lathe, drill press, grinding unit, milling machine, laser, sheet-metal press working machine and tube bending machine. In the non-machine tool category, CNC machining is used in welding machines, electronic assembly, tape laying and filament winding machines for composites.
Advantages of CNC Machining
- CNC machining provides 100 percent accuracy in manufacturing.
- It reduces production time.
- It offers more manufacturing flexibility
- It gives simpler fixturing
- It is good for contour machining
- It decreases human errors
- It is more precise than manual machining
- It can produce complex shapes including three-dimensional shapes
- It can be repeated in exactly the same manner over and over again.
Working of a CNC Machine
Due to the mentioned qualities, CNC Machining is mostly used in jobs which require a high level of precision or very repetitive tasks.CNC machining is used in manufacturing metal as well as plastic parts. Let’s see how it works.
