The system comprises a technological problem definition module, a technological integrated database module, an expert knowledge base, a decision optimization module, an automatic programmable module and a grinding application module. The technological problem definition module is used for storing a plurality of pieces of process case information according to generalized technological problem definition information model normalization requirements and building other modules with data and knowledge mining and rule-knowledge self-learning ability. A complete set of software is integrated and embedded by the aid of Siemens (original equipment manufacturer) system development communication interface programs. The system solves the problems of complicated and changeable current cam shaft grinding environments, process parameter optimization and decision-making difficulty, complex numerical control programs, low similar part decision-making and programming efficiency and the like. Cam shaft part decision-making processing time can be remarkably shortened, processing efficiency is improved, and the performance of a numerical control machine tool is brought into full play.

Description

technical field [0001] The invention relates to a camshaft intelligent grinding process software database system based on a numerical control system. Background technique [0002] The camshaft is one of the key components of the engine. The accuracy and quality stability of the camshaft directly affect the running stability, noise and emission of the engine. At present, although domestic manufacturing enterprises have introduced various advanced numerical control equipment, the machining accuracy of camshafts in the process of numerical control grinding is heavily dependent on the experience of operators. "Method" and "experience" method, which makes the processing quality of parts largely restricted by manual skills and technical level, it is difficult to ensure the consistency of camshaft processing accuracy and the improvement of processing efficiency. [0003] In addition, when processing new materials or new parts, it is necessary to carry out a large number of grindin...

AI Technical Summary

Problems solved by technology

[0010] 1. There are many sources of grinding processing data, the structure is complex, and the standardization and standardization of data research is lacking: the data research is highly dispersed, and the reliability and standardization are poor, resulting in insufficient reliability and versatility of the data

[0011] 2. The reasoning mechanism of the processing technology condition consultation/assistant system of the existing process software and knowledge base is too simple, the solution ability is not strong, and it is difficult to be used to actually guide production

[0013] Most of the existing processing databases, knowledge bases and process software exist independently, and have poor compatibility with the CNC system, and do not have the function of integrated processing with machine tools. There is no model library and algorithm library matching the process software, which is less practic...
