Manufacturing process design

More important than either creep or fatigue in current car design is the effect of environmerit (Chapter 23). An appreciable part of the cost of a new car is contributed by the manufacturing processes designed to prevent rusting and these processes only partly work - it is body-rust that ultimately kills a car, since the mechanical parts (engine, etc.) can be replaced quite easily, as often as you like.

Starting at the top, the assembly data object has one-to-many type of relationship with the part data object, whilst part object has one-to-one type of relationship with the assembly object. This determines the schema for the assembly objeet and bill of materials (BOM) is an example of it. The part object has one-to-one type of relationship with the task sequence object and it is the same viee versa. In practical terms this means that there is always a unique sequenee of tasks to manufacture the part dictated by the material and volume involved. The task sequence object has one-to-many type of relationship with the task object and the task object has a one-to-one type of relationship with the task sequence. This means that a task sequence often contains many different types of tasks. Finally, the task object has one-to-many type of relationship with the material object and equipment object, whilst the material and the equipment objects have a one-to-one type of relationship with the task object In practical terms this means that a task often utihses many different types of materials and equipment to make the parts. The determination of these relationships together with the object attributes lead us to the schema design that can hold all the information required for the manufacturing process design. The data relationships model of Fig. 3.2 integrates the key variables involved and their interactions... 

So in the manufacture of a new product there are many choices open to the engineers and opportunities to provide CAPE tools to facilitate these thought processes. Some of these choices are shown in fig 1 choices about genetic and metabolic networks, about host organism and type of expression system, and of manufacturing process design. 

The manufacturing process design output shall be expressed in terms that can be... 

Similar to chemical/petrochemical plants, the manufacturing system architecture will include manufacturing model as integrated with the manufacturing process design environment i.e. CAD/CAM, as shown in figure A8-1.
