What Machine CNC ?
NC (Numerical Control) machines have evolved into CNC (Computer Numerical Control) machines. A computer is required to set up the software to control the movement of the machine on the CNC machine. Machining programs are read and stored in memory at the same time. When machining, the computer will send commands to the machine to control.
Line interpolation, arc interpolation, torsion, parabola and any solid surface are all tasks a CNC machine can perform. Basically, CNC machines can cut metal into precise, sharp and attractive designs using simple curves like straight lines and even voids inside the workpiece.

CNC machines can be divided by type and control system:
Sort by type:
CNC Drilling Machine
CNC Milling Machine
CNC machine
And CNC machining centers: Capable of machining on a wide range of surfaces and with a wide range of tools.
Divide by control system
Machine control with point-to-point connection (such as drilling machine, boring machine, spot welding machine, punching machine, stamping machine, etc.)
Machines capable of performing displacement along the axis are called flow-driven machines.
The machine has line control, such as 2D machine, 3D machine, 2D1/2 control, 4D control and 5D control.

The function of What machine CNC ?
CNC machine tools are designed to perform a wide variety of tasks, some of which are impossible or difficult to do with traditional NC machines. The main functions of CNC are as follows:
Machine tool control
Error compensation during machining
Advanced programming and operating features
Misdiagnosis
Machine tool control
Machine tool control is the main function of the CNC system. Through computer interface and servo system, it converts machine tool commands into machine tool movement.
CNC has the benefit of being able to quickly combine multiple control capabilities into a single soft-connected controller. Some control operations, such as circular interpolation, are performed more efficiently by hard-wired circuits than by computers, leading to two alternative types of controllers in CNC. CNC is not hybrid and hybrid is not CNC.
Error compensation during machining
This is a function closely connected with the control of machine tools. It focuses on the dynamic correction of machine tool movements that encounter errors or require parameter changes during machining. When machining CNC machines, there are several forms of error compensation:
When a measuring tool or measuring instrument detects an inaccuracy in the machining process, it must be corrected.
Adaptive control can be adjusted for cutting speed, feed amount, or both.
When an error detector (probe) is used to place a reference point on the workpiece, recalculate the coordinates. Adjust the tool adjustment amount based on the radius (milling tool) and length (turning tool).
Calculate the expected life of the breaker and replace it as needed.
Advanced programming and operating features

Chẩn sai
The machine tools are often complex and expensive. The more complex, the more likely it is to fail, causing the system to stop working. At the same time, it requires the system maintenance team to be trained at a more proficient level to be able to respond and repair.
CNC machines are often equipped with the ability to misdiagnose to aid in maintenance and repair work. These diagnostic capabilities are getting better than ever. Some of the functions that the diagnostic system is capable of performing are:
Indicate the cause of the shutdown so that the maintenance team can fix it in time. Give an alarm signal about impending failures in a certain part or part. The maintenance team will replace the part or part at the scheduled shutdown time, thus avoiding unplanned stoppage of production.
For the components that are considered to be vulnerable, it is advisable to arrange a backup element, so that when there is a problem, the diagnostic system will automatically separate the damaged element. At the same time, the backup element is activated, so that the repair work does not disrupt the normal operation of the system.
Advantages what machnie CNC ?
Compared with traditional NC machines, CNC machines have outstanding advantages such as:
To import a program into computer memory, the tape and tape reader are used only once. Because the reading unit is often considered the least reliable component in a standard NC system, this advantage increases the reliability of the system.
Tape editing at the machine: while the tape is being inspected at the machine tool, the program can change or even optimize the tape (such as cutting path, cutting speed and feedrate).
Convert Inches prepared on tape to metric units (international standard): CNC can convert Inches prepared on tape to metric quantities.
Greater flexibility: When compared to standard NC, this is the most significant advantage. Due to its adaptability, it is possible to add additional control capabilities as needed with moderate ease and low cost. The possibility of becoming obsolete and losing one’s job is also reduced.
Users can write additional applications: Users can add their own specialized programs to the object program by writing their own programs. They are usually macros or subroutines stored in the memory of the CNC machine and can be invoked by the workpiece program to perform machining sequences that repeat as often as necessary.
