Research on Drilling Control Method of Ammunition Shell Based on Fuzzy Algorithm

Aiming at the technical requirements of high precision, unmanned and flexible drilling on the curved surface of large-size ammunition shells, a gantry-type curved surface automatic drilling system is designed based on fuzzy algorithm. The system selects the feed displacement of the drilling spindle and the rotation speed of the drilling rotary motor as the drilling characteristic quantities, and establishes the drilling depth fuzzy alarm model through the steps of fuzzy processing, establishment of fuzzy reasoning and calculation of the fuzzy alarm query table. The hardware composition and software design scheme of the drilling system are introduced. It has been proved that this method can realize the precise control of the drilling depth of the surface of the large-size ammunition shell, and the control accuracy is 0.2mm, which can meet the actual production needs.
