Numerical Control (NC) is a technology that enables the automatic operation of machines using a computerized control system. NC systems control the movements and operations of machines through computers with a specific programming language. These systems enable precise machining of complex workpiece and play an important role in industrial production processes.
An NC system controls the movements required for machining the workpiece using a predetermined program. This program is usually created using a computer interface or specialized NC programming software. The program defines the dimensions, shape, cutting path and other process parameters of the workpiece.
The NC system generates numerical commands or codes that determine the movements required for machining the workpiece. These commands determine the axis movements of the machines, speeds and other operations. The NC system performs the operation by transmitting these commands to the control system of the machines so that it can be integrated with various machines that can perform cutting, drilling, milling, turning and other operations necessary for machining the workpiece. A more technological version, called CNC (Computer Numerical Control), involves the use of computers and digital control systems.
Precision and Quality: The NC system enables workpieces to be machined with high precision, resulting in quality results.
Repeatability: The NC system provides the ability to perform the same operation over and over again, which increases the consistency of workpieces.
Ease and Flexibility: NC systems enable complex and precise operations and provide flexibility for machining different workpieces.
Productivity and Efficiency: The NC system enables workpieces to be machined more quickly and efficiently, which helps speed up production processes and reduce costs.
Reduction of Human Error: The NC system reduces the risk of human error, which ensures accurate and reliable machining of workpieces.
Ease of Integration: The NC system can be integrated with different machines and used in industrial production processes.
Numerical Control (NC) systems play an important role in industrial production processes and enable complex and precise operations. These systems improve the quality of workpieces.
G & M Codes
The G and M codes used in Numerical Control (NC) systems are ISO coding systems for controlling machine machining processes. Each code represents a specific operation or command and tells the machine what to do.
G Codes:
G codes are used to specify certain types of movements, cutting operations, positioning commands and machining modes in the machining process. These codes determine what type of movement is made by the machine during the machining of the workpiece. For example, the G01 code represents a linear cutting motion, while the G02 code represents an arc motion.
Some common G codes are:
M Codes
M codes are used to indicate certain functions in the machining process, such as controlling the sequence of operations, enabling or disabling auxiliary functions, controlling the coolant pump, etc. These codes tell the machine to perform certain commands during the machining process. For example, code M03 starts the spindle rotating clockwise, while code M05 stops the spindle.
Some common M codes are:
G and M codes are used within the NC programming language and are used to instruct the machine to perform the desired operations. These codes ensure that the machine operates correctly and safely and that the workpiece is processed in the desired way.
