Abstract
Design and construct an intelligent machining unit for needle valve fittings in response to the demand for intelligent machi-ning of needle valve fittings.Analyze the machining dimension data and improve the machining method for matching the clearance be-tween needle valve components;Construct a mathematical model for gap pairing problem and solve it using an improved genetic algo-rithm to achieve optimal gap pairing of needle valve components.The model has been validated on site with a success rate of approxi-mately 85%;Based on transfer learning,an OCR model is trained to recognize the production sequence number of needle valve bodies with an accuracy rate of 95% .The data of the needle valve fitting process is associated with it to achieve automatic data recording and facilitate quality traceability.
