Main functions of CNC milling machine

Although the CNC systems configured by various types of CNC milling machines are different, the functions of various CNC systems are basically the same except for some special functions.

1. Point control function

This function can realize hole system machining that requires high mutual position accuracy.

2. Continuous contour control function

This function can realize the interpolation function of straight line and circular arc and the processing of non-circular curve.

3. Tool radius compensation function

This function can be programmed according to the dimension of the part drawing, without considering the actual radius size of the tool used, thereby reducing programming.

complex numerical computations.

4. Tool length compensation function

This function can automatically compensate the length of the tool to meet the requirements for the adjustment of the length of the tool during processing.

5. Scale and mirror processing functions

The scale function can change the coordinate value of the programmed processing program according to the specified scale to execute. Mirror machining is also known as axisymmetric machining, if the shape of a part is about the seat

If the target axis is symmetrical, as long as one or two quadrants are programmed, the contours of the remaining quadrants can be realized by mirroring.

6. Rotation function

This function can execute the programmed machining program by rotating it at any angle in the machining plane.

7. Subroutine calling function

Some parts need to repeatedly process the same contour shape at different positions, take the machining program of this contour shape as a subprogram, and repeat the process at the required position.

Repeat the call to complete the processing of the part.

8. Macro function

This function can use a general instruction to represent a series of instructions to achieve a certain function, and can operate on variables, making the program more flexible and convenient.
