The geometric errors of CNC machine tools come from the manufacturing defects of the machine tool, the coordination error between the machine tool components, the movement of the machine tool component, and the static change position

When the machine tool error changes, the amount of compensation must be changed, and the compensation agency must be re -made, corrected ruler, or re -adjusted the compensation institution. Hardware compensation has the disadvantages that cannot solve random errors and lack of flexibility.

The thermal error of the machine tool is mainly caused by the thermal deformation of the machine tool component caused by the thermal source of the machine tools such as motor, bearing, transmission, hydraulic system, environmental temperature, and coolant.

The study of CNC ride processing errors is an important component and development direction in modern machinery manufacturing, and has become a key technologies for improving competitiveness. skills requirement. Error compensation technology can meet the high accuracy and low cost of the actual production requirements of the factory. The heat error compensation technology can correct the hot drift error between the spindle (or workpiece) and the cutting tool, improve the processing accuracy of machine tools, reduce waste products, increase production efficiency and economy economy benefit.
