What is computer aided production planning?
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.
What are the components of CAPP?
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. CAPP has recently emerged as the most critical link to integrated CAD/CAM system into inter-organizational flow.
What are the benefits of CAPP?
16.11. 4 Benefits of computer-aided process planning
- CAPP can give more complete and detailed process plans.
- Process planning and production lead time is reduced.
- CAPP can give faster response to engineering changes.
- Greater process plan consistency is ensured.
What are the types of CAPP?
These are the types of CAPP:
- Generative Computer Aided Process Planning (G CAPP)
- Variant Computer Aided Process Planning (Variant CAPP)
- Retrieval Computer Aided Process Planning (Retrieval CAPP)
Why do we use computer aided process planning?
Often-cited benefits of CAPP include general efficiency in manufacturing, better use of raw materials, improved production scheduling, fewer calculation errors and labor saving.
What are the benefits of computer aided process planning?
Reduced process planning and production leadtime; faster response to engineering changes. Greater process plan consistency; access to up-to-date information in a central database. Improved cost estimating procedures and fewer calculation errors.
What are the various approaches available for computer aided process planning?
Traditionally two approaches are recognized for computer aided process planning, the variant approach and generative approach. In variant approach the GT principles are used. Further making use of the similarity in design or manufacturing of the parts are used in producing the new process plans.

What are the two types of CAPP?
There are two approaches for computer aided planning process: retrieval type CAPP systems and generative CAPP systems. Both these systems have been described below.

What is the purpose of Computer Aided Process planning?
Computer Aided Process Planning • As we have already discussed, the primary purpose of process planning is to translate the design requirements into manufacturing process details. • Thus a system was developed in which design information is processed by the process planning system to generate manufacturing process details.
What do you mean by computer aided manufacturing?
•CAM – computer aided manufacturing. Generally refers to the computer software used to develop the Computer Numerical Control part programs for machining and other processing applications. •CAPP – computer aided process planning.
How are computers used in the manufacturing process?
The use of computer to generate the process plans for the complete manufacture of products and parts. •CATD – computer aided tool design. Computer assistance to be used for developing the tools for manufacture such as jigs and fixtures, dies, and moulds. Computer Applications •CAP – computer aided planning.
When do you need a part process plan?
A part process plan may reveal that new tools are needed to produce the part. If this is the case, the process planner (a person who develops the process plan) initiates a request for design or purchase of new tools so that tIie~ become available at the time of manufacturing. Planning and ordering of material.
