3DCS Advanced Analyzer and Optimizer for Tolerance Analysis

637 Aufrufe

Veröffentlicht am

Use AAO, Advanced Analyzer and Optimizer, to quickly optimize your designs for maximum quality at the lowest cost.

Excellent for quickly testing and changing many tolerances at once, AAO is a great way to speed up modeling, and more importantly, speed up the process of testing and checking new tolerance strategies.

As an inexpensive add-on to any of DCS's 3DCS software suites, including the embedded CATIA versions, AAO is a simple way to save time and increase efficiency.

  8. 8. • Quickly identifies where design is sensitive to variation • Enhanced GeoFactor results • Change individual tolerance ranges for instant results • Show GeoFactor or Percentage Contribution • Global color scaling based on adjustable sliders Advanced Analyzer Matrix
  9. 9. Critical Tolerance Identifier Measurements Tolerances Percent Contribution
  10. 10. • Pp*: spec limits, no mean shift • Ppk*: spec limits, mean shift • Out%: significant out-of-spec results • Ave%: average % contribution per measurement *Process Performance, Process Performance Index • Sigma: no spec limits, no mean shift HLM Sensitivity + GeoFactor** Quantifies the effect of tolerances and assembly variation on the measures simultaneously and globally Calculates each measure separately CTI Results Identify the greatest contributing tolerance globally **Geofactor is a 3DCS Add-on often packaged with 3DCS Suites

  12. 12. Achieve desired quality at minimum cost Goal Value (spec lim) Max, Min, Lock, Cost Opt Meas Opt Tol Total Current Cost, Total Optimized (Minimum) Cost Input per Measure per Tolerance Optimizer Output *Assumption: larger tolerance = less cost
  13. 13. Measures • Goal Value: check all spec limits, default is fine Tolerances • MaxTol/MinTol – Profile, MinTol = 1.0mm – Position, MinTol = 0.5mm • Locking – Tooling (no ability to change) – Size (low influence on model) • Cost – Profile tolerance costs 20% of Position tolerance – All other tolerances equal

Achieve best possible quality at a defined cost Goal Value, Weight Max, Min, Lock, Cost Total Available Budget Opt Meas Opt Tol Total Current Cost, Total Optimized (Minimum) Cost, Optimized Quality Value Input per Measure per Tolerance Optimizer Output *Assumption: Weight and Cost are relative values
  17. 17. Measures • Goal Value: check all spec limits, default is fine • Weight: set unimportant measures to zero Tolerances • MaxTol/MinTol – Profile, MinTol = 1.0mm – Position, MinTol = 0.5mm • Locking – Tooling (no ability to change) – Size (low influence on model) • Cost – Profile tolerance costs 20% of Position tolerance – All other tolerances equal Other • Total Available Budget: estimated cost (assume unlimited to see best quality)
