The invention belongs to the technical field of
digital control of electromechanical integration, and relates to an
intelligent control method with the three-stage
processing self-optimization function. The
intelligent control method comprises the following steps: firstly, optimizing and an executing
processing program according to optimum
processing parameters; secondly, detecting the current and the
power supply voltage of a main motor in real time during processing, taking the current as a decision-making value, the
voltage as an supplementary means and the variation
delta af of the feeding speed af as a
system adjustment value, and realizing closed-loop feedback fuzzy control of the processing process; and thirdly, taking a trigger
signal of a three-dimensional measuring head as an input mark value after completing the procedure of detection of geometrical information of workpieces, reading the actual coordinate of a current measuring point after detecting the input mark value of the measuring head, estimating errors of processed workpieces after measuring all the measuring points, and performing secondary self-
adaptive optimization and adjustment on the processing program. The
intelligent control method can realize self-optimization of a
digital control program; and a
digital control system can acquire shape and
position error information of the workpieces in time, so that parameters in subsequent technology are convenient to adjust.
