Answer 1

Answer:

Computer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing. CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.

Computer-aided process planning (CAPP) helps determine the processing steps required to make a part after CAP has been used to define what is to be made.

CAPP programs develop a process plan or route sheet by following either a variant or a generative approach.

The variant approach uses a file of standard process plans to retrieve the best plan in the file after reviewing the design. The plan can then be revised manually if it is not totally appropriate.

The generative approach to CAPP starts with the product design specifications and can generate a detailed process plan complete with machine settings.

CAPP systems use design algorithms, a file of machine characteristics, and decision logic to build the plans.

Expert systems are based on decision rules and have been used in some generative CAPP systems.
