What You Can Do

Upload your manufacturing data and receive rigorous statistical analysis identifying process issues, bottlenecks, and root causes. Claude designs optimized experiments (DOE) tailored to your constraints and generates actionable improvement recommendations with statistical confidence levels backed by your actual data.

Features

Process Data Analysis

Analyze production metrics, cycle times, defect rates, and quality data to identify performance patterns and statistical anomalies

Design of Experiments (DOE)

Generate optimized experimental designs (factorial, response surface, Taguchi) considering your process constraints, factor ranges, and resource limits

Statistical Significance Testing

Perform hypothesis testing, confidence interval analysis, and p-value calculations to validate whether process changes produce real improvements

Root Cause Analysis

Use correlation analysis, control charts, and Pareto principles to isolate the actual drivers of quality issues and variability

Process Capability Analysis

Calculate Cpk, Pp, and Ppk metrics to quantify how well your process meets specifications and prioritize improvement targets

Quality Control Recommendations

Design SPC charts, define control limits, and recommend sampling strategies aligned with your defect costs and production volume

Improvement ROI Estimation

Estimate financial impact of proposed changes including scrap reduction, rework savings, cycle time gains, and labor efficiency improvements

Example Output

Example 1: Process Capability Analysis

  • Current Cpk: 0.89 (process centered but too variable)
  • Recommended actions: Reduce tool wear variance (±0.05mm → ±0.02mm), adjust coolant temperature range
  • Estimated impact: Cpk → 1.33, defect reduction 35%

Example 2: DOE Recommendation

  • 2³ factorial design (8 runs) testing: feed rate, spindle speed, depth of cut
  • Interaction effects detected: Feed × Spindle Speed affects surface finish
  • Optimal settings identified with 95% confidence

Example 3: Root Cause Summary

  • 68% of dimensional failures traced to tool deflection (single dominant cause)
  • 22% from spindle runout drift over 4-hour shifts
  • Recommended experiment: Compare rigid tool holder + automated spindle warm-up protocol

What's Included

  • Statistical Analysis Templates: Ready-to-use spreadsheet templates for data entry, control charts, capability analysis, and hypothesis testing calculations
  • Experiment Design Framework: Step-by-step guidance for DOE setup including factor selection, run order randomization, response measurement, and result interpretation
  • Quality Metrics Dashboard: Instructions for building control charts, Pareto diagrams, and trend analysis visualizations from your production data
  • Process Improvement Action Plan: Prioritized recommendations with estimated impact, implementation effort, resource requirements, and success metrics
  • Statistical Validation Checklist: Verification steps ensuring data quality, assumptions met, results reproducible, and conclusions statistically sound
