Research on Knowledge Visualization for Process Planning
In the field of industrial manufacturing,a large amount of process information is generated during the manufacturing processes.In the knowledge economy era,effective utilization and timely trans-mission of information are crucial.However,the process has poor real-time performance and low visuali-ty in process operations,which results in a"black box"of process knowledge.Regarding this issue,a method based on virtual reality and 3D visualization for process knowledge visualization is proposed.Process information is extracted and digitized based on the matching of process information rules.By adopting OPC UA communication protocol,real-time data transmission among operational devices was achieved.Virtual reality technology is utilized to establish a knowledge visualization model for process operations,enabling virtual simulation of the process.Utilizing 3D visualization technology,processing knowledge on the visual operation interface can be dynamically presented,facilitating real-time monitor-ing and management by operators.A visualized four-dimensional model was established based on an example of bearing assembly in the experiment.By visualizing the process state change logic of bear-ing assembly and real-time mapping of 16 key process parameters,the process knowledge visualization of the assembly process was achieved,solving the problem of delayed information transmission and low visualization level in the process,and verifying the effectiveness of the proposed process knowledge visu-alization method.
