Retrieval (variant) CAPP systems

This is an older CAPP system based on Group Technology and parts classification & coding. Standard process plans are stored in computer files with each part code number - Plans are based on current part routing - For each new part, the standard plan is edited - If file doesn't exist, can search a similar code name and edit it to become the standard plan for the new part - Final step is the process plan formatter which may call on other application programs e.g. design cutting conditions, computing cost estimates
