The collaborative computer-aided machining process planning is an element in the process chain of extended enterprises in Automotive Engineering. Meanwhile in practice it is an approach engaged by both OEMs (Original Equipment Manufacturers) and their long-term machine suppliers. In general the form of collaborative organizations between them is based on the continuous work and data flows in machine building. This paper highlights the modeling approaches and application possibilities of a new digital planning IT-tool, discusses the aspects of its prospective advantages in machining process planning by OEMs and suppliers. This 1T-Tool for process planning is investigated, regarding collaborative planning of machining process for Powertrain production in Automotive Industry. The production transfer line of connecting rod is the studied scenario that is used as an application reference. Comparing with conventional alphanumeric planning, the efficient CAD-based IT-tool provides the users more flexibility and merits with high qualities, such as process structure, 3D-visualization, timing analyze, and machining tool descriptions. Digitalization of machining process planning makes it possible and profitable to standardize the planning process in OEMs internally, and with their machine tool builders, finally enables the reorganized distributed activities of machining process planning.
