The Design for Assembly (DFA) - index calculator computes Design for Assembly index.

INSTRUCTIONS: Choose the preferred units and enter the following:

  • (Nm)  This is the theoretical minimum number of parts
  • (tm) This is the minimum assembly time per part
  • (TA)  This is the estimated total assembly time (s)

Design for Assembly (DFA) Index:  The calculator returns the index.

Design for Assembly Principles

  • Minimal Number of Parts
  • Parts with Obvious Locations or Self-locating features
  • Parts with self-fastenings
  • Minimal amount of reorienting components or complete body
  • Smooth assembly design for retrieving, handling and inserting parts.
  • Emphasis on Top-Down designs
  • Standardized parts
  • Modular Design
  • Frame or base part for components
  • Symmetry
