The principles of CNC operation
· Movement of X, Y, Z axis are controlled by a motor which supplies either Alternating current or Direct current.
· Movement of the machine is done by giving commands.
· All the operations are carried out by codes like speed, feed, depth of cut, etc.
· For each operation separate code is available.
· The warning system is available to save guard the various operations and components.
The main determining factor of CNC machine tools is the accuracy of programming. Programming needs to be done by the system. In the machining industry, the most commonly used systems for CNC machine tools are these: Japan FANUC CNC system, Germany Siemens CNC system, Japan Mitsubishi CNC system, Germany HEIDENHAIN CNC system and so on.
