FAQ
Computer numerical control (CNC) is the automation of machine tools where computers executing pre-programmed sequences of commands. CNC machining is a manufacturing process where pre-programmed computer software dictates the movement of tools and machinery. The process can be used to control complex machinery, from grinders and lathes to mills and routers.
When a CNC system activated, the desired cuts are programmed into the software and dictated to corresponding tools and machinery, which carry out the dimensional tasks as specified, much like a robot.
There are basically five different types of CNC machines:
- Plasma Cutting Machine.
- Laser Cutting Machine.
- Vertical and Horizontal Milling Machine.
- Router Machine
- CNC Lathe Machine.
Jigs and fixtures increase the productivity by eliminating the positioning frequent checking & individual marking. The operation time is also reduced due to increase in speed, feed and depth of cut because of high clamping rigidity. Jigs & fixtures facilitate the production of articles in large quantities with high degree of accuracy, uniform quality and interchange ability at a competitive cost. Higher production, reduction in scrap, easy assembly & savings in labour cost results in ultimate reduction in unit cost.
There are major differences between PLC (Programmable Logic Controller) and CNC(Computer Numerical Control) is in the execution of the program. PLC is sequential but CNC is conditional. CNC is a type of application used to control a multi-axis machine tool for example milling machine or lathe.
