The analysis for DRBFM is modeled after a linkage between a good design review and FMEA. A comprehensive, well-done FMEA can be considered one of the inputs (plus many other preparations sheets defined in the methodology) to decide the scope of a DRBFM but an FMEA is not required since the focus is based on the changes and interfaces.
[39] [40] [23] The FMEA worksheet is hard to produce, hard to understand and read, as well as hard to maintain. The use of neural network techniques to cluster and visualise failure modes were suggested starting from 2010. [41] [42] [43] An alternative approach is to combine the traditional FMEA table with set of bow-tie diagrams. The diagrams ...
Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology.
Depending on various types of manufacturing processes there are set guidelines for DFM practices. These DFM guidelines help to precisely define various tolerances, rules and common manufacturing checks related to DFM. Rule based guidelines which can be referred to while designing parts are mentioned below.
Rule based DFM analysis for deep drawing. Deep drawing is a widely used cold sheet metal forming process to draw the sheet metal in forming dye of desirable cross-section using mechanical force of the punch. DFM refers to design for manufacturability. DFA refers to design for assembly. DFMA stands for design for manufacture and assembly. It is ...
Specifying material 25 or 30 percent thicker than the finished-part thickness is usually sufficient to allow for such reduction in wall thickness. However, material too thick for easy spinning should not be specified. Both extra-thick and extra-thin materials make spinning more difficult.
Design for excellence (DfX or DFX) is a term and abbreviation used interchangeably in the existing literature, [1] [2] [3] where the X in design for X is a variable which can have one of many possible values. [4]
Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). It is a general type of design methods or tools whereby functional performance and/or other key product life-cycle considerations such as manufacturability, reliability, and cost can be optimized subjected to the capabilities of additive manufacturing technologies.
