Windchill: Process Planning

Hello,

There are a couple of different pieces of manufacturing information involved here, and they serve different purposes.

First, SS SEAT, SS MAINFRAME, and SS MOTION CONTROLS are the names of parts or assemblies in the manufacturing structure. When you work with occurrences and reference designators, you are not simply naming or describing those parts a second time.

Think of the part as telling you what the component is, while the occurrence tells you where that particular instance is being used. You might use the same screw in four different places. It is still the same part with the same part number, but each use of that screw is a separate occurrence.

In Exercise 5, you are not being asked to determine where each screw goes. The occurrence records already exist in the training data so that you can focus on understanding part allocation. The exercise uses the previously designated occurrences to associate parts with the operations in which they are used or assembled. The goal is to demonstrate that part allocation connects the product structure to the manufacturing process by defining when a part is used and which operation is responsible for it.

Put those pieces together, and you can see how the different types of manufacturing information work together:

• The mBOM identifies what needs to be built.
• Occurrences identify specific uses of components within that manufacturing structure.
• Part allocation connects those components to the operations where they are used or assembled.
• The resulting process plan can then provide that information downstream in dynamically generated work instructions.

As for ERP, Windchill does support integration with other enterprise applications, but ERP integration isn’t covered in this course. If you would like to explore how Windchill works with other enterprise systems, the Windchill 13.1.2.0 Help Center is the best place to start.
