There are various brands and models of CNC milling machines on the market, and the CNC systems they are equipped with are also different. But regardless of the type of CNC system, except for some special functions, their main functions are basically the same.
1. Point control function: CNC milling machines can perform high-precision hole system processing, such as drilling, reaming, dumpling holes, and tweezers holes.
2. Continuous contour control function: This control function can achieve continuous contour control of tool motion trajectory through interpolation of straight lines and arcs, enabling it to process planar workpieces composed of two geometric elements: straight lines and arcs. This function further extends to the ability to process spatial surfaces.
3. Tool radius compensation function: This function can be programmed based on the marked dimensions of the workpiece pattern, without considering the actual radius size of the tool used. It can reduce complex numerical calculations during the programming process.
4. Tool length compensation function: Its function will automatically compensate for the length of the tool, thereby adapting to the requirements for adjusting the length size of the tool during processing.
5. Proportional and mirror machining functions: Proportional functions allow the programmed machining program to be executed by changing the coordinate values proportionally. Mirror machining, also known as axisymmetric machining, if the shape of a part is symmetrical about the coordinate axis, then as long as one or two quadrants are programmed, the contours of the other quadrants can be achieved through mirror machining.
6. Rotation function: On the milling machine, this function can execute the programmed machining program by rotating it at any angle within the machining plane.
7. Subprogram calling function: Some parts require repeated machining of the same contour shape at different positions. The machining program of this contour shape is used as a subroutine, and repeated calling at the desired position can complete the machining of the part.
8. Macro program function: This function can represent a series of instructions that implement a certain function with a total instruction, and can perform operations on variables, making the program more flexible and convenient.
The above are the main functions of CNC milling machines. To achieve flexible and convenient use of milling machines, the above functions are essential.
