CNC milling machine is a kind of automatic processing equipment, which has the same structure as the machining center, but without the tool library. Various CNC milling machines are configured with different CNC systems, but their main functions are the same.

Main functions of several commonly used CNC milling machines:

1. Milling

CNC milling machines should generally have the linkage function of more than three coordinates, be able to carry out linear interpolation and circular interpolation, and automatically control the rotation of the milling cutter for milling relative to the workpiece movement. The greater the number of coordinate linkage axes, the lower the clamping requirements for the workpiece and the larger the processing range.

2. hole and thread processing

The fixed size hole machining tool can be used for drilling, expanding, reaming, spot facing, boring, and another machining, and the milling cutter can also be used to mill holes of different sizes.

3. tool compensation function

Generally, it includes tool radius compensation function and tool length compensation function.

4. Point control function

This function can realize the hole system machining with high requirements for mutual position accuracy.

5. Continuous contour control function

This function can realize the interpolation function of straight lines and arcs and the machining of the non-circular curve.

6. absolute coordinate and incremental coordinate programming

The coordinate data in the program can adopt absolute coordinates or incremental coordinates, which makes the data calculation or programming more convenient.

7. feed speed and spindle speed adjustment

Generally, the control panel of the NC milling machine is equipped with multiple switches for the feed speed and the spindle speed, which are used to adjust the actual feed speed and the spindle speed at any time according to the processing state and the program setting value during the program execution, to achieve the best cutting effect. Generally, the adjustment range of feed speed is 0%~150%, and the adjustment range of spindle speed is 50%~120%.

8. fixed cycle

The fixed cycle is a subroutine solidified into the G command, which adapts to different processing requirements through various parameters. It is mainly used to realize some typical processing actions that need to be repeated many times, such as the processing of various holes, internal and external threads, grooves, etc. The use of fixed cycles can effectively simplify the programming. However, different CNC systems have great differences in the definition of the fixed cycle, which should be paid attention to when using.

9. workpiece coordinate system setting

10. data input and output and DNC function

11. subroutine calling function

Some parts need to repeatedly process the same contour shape at different positions. By taking the machining program of this contour shape as a subroutine and calling it repeatedly at the required position, the machining of this part can be completed.

12. Macro program functions

This function can use a total instruction to represent a series of instructions to realize a certain function and can calculate variables, making the program more flexible and convenient.
