11🛡️ Process Capability, Cpk Analyzer
22
33A statistical tool modeled to measure process capability and estimate production yield.
4- Key Features
5- • Numbered Data Entry: A sidebar tracker providing live "Point #" feedback (up to 60 points) to help users stay organized during manual key-in.
6- • Statistical Metrics: Calculates Mean, Standard Deviation (ϭ), Cp, and Cpk.
7- • PPM Analysis: Provides a detailed breakdown of "Defects per Million" (PPM) occurring above the USL and below the LSL.
8- • Automated Audit Reports: Generates a professional PDF containing:
9- o Project summary and spec limits.
10- o Individuals Control Chart and Capability Histogram.
11- o A full Measurement Data Log for audit transparency.
