Automatic process step design method based on knowledge reasoning

Abstract

The invention discloses an automatic process step design method based on knowledge reasoning, and the method comprises the following steps: 1, checking process basic information, and checking whether inherited or created process level information meets the requirements of a current process or not; 2, automatically dividing process steps, taking out the procedure nodes determined in the step 1 one by one, and automatically calculating the number of process steps of the current procedure according to the precision requirement and the procedure cutting thickness; step 3, processing parameter recommendation and adjustment: selecting cutting parameters according to a parameter selection strategy and enterprise requirements, verifying the cutting parameters, and adjusting the parameters according to a parameter adjustment algorithm; and step 4, revision and analysis of the three-dimensional technological procedure: after the system automatically completes the design of the process steps, looking up the result and revising same interactively, and publishing the revised technological procedure at the same time. The method can automatically determine the number of the process steps and recommend and adjust the processing parameters, so that the intelligence and automation level of the process compiling is improved, and the efficiency and quality of the process compiling are improved.

Description

technical field [0001] The invention relates to the technical field of process design, in particular to an automatic process step design method based on knowledge reasoning, which is mainly used for automatic division of process steps and automatic recommendation and adjustment of process parameters in the process of process specification preparation. Background technique [0002] Process design serves as a bridge connecting product design and product manufacturing. The process data generated by it is one of the most important data in the product life cycle, and it is also an important basis for enterprises to formulate production plans and carry out production scheduling. play a very important role in the process. The process design process has the characteristics of high professional knowledge requirements, many disciplines involved, a wide range of influence, and complicated work content. Therefore, information and knowledge-based means must be used to assist craftsmen in...

Problems solved by technology

[0004] The method of reasoning based on typical characteristics is suitable for the determination of the process design scheme at the process level, but the application effect is not good for the automatic design of the process steps

For the application of process knowledge, similar processes are mostly reused directly, and process parameters are directly used, which cannot be automatically adjusted according to the actual situation. There is no method and application of process-level parameter reasoning
