96
Q

Essayy

Objectives of Desiging for Producibility?

A

— The quantity and variety of COMPONENTS utilized in system design should be held to a MINIMUM. common and standard items should be selected where possible

– The MATERIALS selected for constructing the system should be STANDARD, available in the quantities desired and at the appropriate times, and should possess the characteristics for easy fabrication and processing.

– The DESIGN configuration should be SIMPLE, to the extent that the system (or product) can be produced by more than one supplier.

– The DESIGN configuration should allow for the EASY ASSEMBLY (and disassembly as required) of system elements; assembly methods should be simple, repeatable, and economical and should not require the utilization of special tools and devices or high personnel skill levels.
