NexSPC fully supports the new AIAG-VDA 2026 SPC standard. Our automated engine eliminates Cpk miscalculations caused by tool wear and non-normal data.…
AIAG-VDA 2026 SPC manual recognizes real-world variation and classifies time-dependent process distributions into four categories: ABCD.…
Within a quality control system, Pmk and Ppk are not redundant metrics, but rather distinct diagnostic tools used at different stages.…
Discover why SPC is the true underlying operating system of smart manufacturing. Learn the five crucial thresholds for SPC implementation, including MSA, data traceability, and OCAP, and how nexSPC powers the industrial AI data closed loop.…
This article addresses quality engineers on how to handle auditor questions regarding why all 8 SPC rules aren't used. It argues that indiscriminately using all rules increases Type I errors (false alarms), destroys process stability, and misjudges physical laws. Rules must match process models and be backed by actionable Out-of-Control Action Plans (OCAP) supported by structured data.…
Discover the 5 non-negotiable prerequisites for CPK calculation under the new AIAG-VDA SPC manual. Learn why MSA, control charts, normality tests, 25 subgroups, and data traceability are mandatory for process capability, and how NEXSPC 4.0 automates compliance.…
