Problems solved by technology

Due to the low ability of the CNC system to identify and deal with unpredictable, fuzzy and uncertain situations in the cutting process, in complex environments and changing conditions, the workpiece material, spindle speed, feed rate, tool trajectory, etc. , cutting depth, machining allowance and other processing parameters cannot be dynamically adjusted in real time according to external interference and random factors in the field environment, let alone randomly correct the set value through the feedback control link

Embodiment Construction

[0032] As shown in Figure 1, it is a system structure diagram of the present invention, in the figure: the upper part is the parameter optimization matching system part, and the lower part is the intelligent fuzzy controller. The parameter optimization and matching system is a set of software based on the Window2000 Professional operating system running on a PC. The optimization system software is based on the highest processing efficiency as the optimization goal. According to the processing depth, processing material and corresponding tool and machine tool parameters of the processing characteristics Constraint conditions are optimized and calculated, and the adaptive power target constraint value and the NC program adopts the spindle speed and feed speed. The software further provides matching rule parameters for online adjustment of the spindle speed override. The software uses the RS232 communication port to match the parameters. Adapt the target value to the fuzzy intelli...
