Research on Process Planning about Shaft Parts of Aeroengine Based on Typical Process

In order to improve the efficiency of process planning for shaft parts of aeroengine and to realize the rapid forming of part process,it presents a method to process planning based on typical process.Based on the typical process case and typical process template,a new process planning can be generated by character of different shaft parts.It puts forward some key technologies of process planning such as case modeling,case process searching,case process editing etc.It shows the detail about typical process template,including building of part parameters base,realizing of process parameter-based relation and an application example.
