Abstract: Process digital definition is one of the critical tasks in process management and product definition. In order to standardize the content and methods of process digitization, the scope, the detailed content and its definition method were established based on computer aided process engineering research. In allusion to the engineering application situations, a collaborative work pattern based on Web was brought forward, and this work consummates the concept of generalized engineering dataset (GED). Then, a concurrent & collaborative working process was discussed based on GED concept linked with the apart-organization status quo inner country aviation enterprise. Process digital definition is the precondition and foundation for the transformation from digital design to digital manufacturing, and also the efficient means for a enterprise to reduce cost, eliminate waste and promote competition ability. The result of this work will be the transformation power from traditional manufacturing to digital manufacturing pattern.
