Free Online Robust Design (Taguchi Method) Tool
Plan and analyze robust experiments using Orthogonal Arrays to optimize product and process quality.
How to Use This Tool
- Load Data or Start Fresh: Use "Load Example Data" for a quick demo or fill in the setup fields yourself. Use "Reset Form" to start over.
- Experiment Setup: Give your experiment a clear name and a concise objective.
- Define Factors and Levels: A "factor" is a variable you want to test (e.g., Temperature, Pressure). "Levels" are the specific settings for that factor (e.g., 100°C, 120°C for Temperature).
- Response and S/N Type: Enter the name of what you are measuring (the "Response Variable") and select the appropriate Signal-to-Noise (S/N) ratio (Smaller is better, Larger is better, or Nominal is best).
- Generate Design: Click "Generate Taguchi Design." The tool will create an experimental plan.
- Enter Data: Perform the experiments and enter your measured result for each run.
- Calculate and Analyze: Click "Calculate Full Analysis." The full report will appear below. Each new calculation will be added below the previous one.
- Export: Click "Export to Excel" at the bottom of the report to save the results of the *last* analysis.
