Reliability, Tolerances, Statistical Process Control (SPC) and Process Capability

A resource page for those getting started or looking for just the right information.

Having a stable and capable process for all your components and assembly processes enables you and your team to create reliable products for your customers. It also permits you to maintain a robust and available manufacturing process.

Statistical Process Control and Process Capability

Here is an abbreviated abstract listing of SPC related webinars, courses, and articles on Accendo Reliability.

Webinar — Process Capability, Tolerance, and Reliability on how understanding process capability helps design teams set appropriate tolerances for critical part dimensions.

Webinar — 10 Keys for Maximizing the Benefits of Your SPC Program is a content-packed event designed to provide multiple practical ways to improve your program today.

Webinar — Sample Size Impact on SPC explores a rational way to select sample sizes for use in effective control charting.

Webinar — Understanding and Controlling Process Variation is a discussion on the importance of process stability on the reliability performance of your product.

Webinar — Reliability and Statistical Process Control explores what happens if the assumed stability of your vendor’s component assembly process is not actually true.

Course – Statistical Process Control & Process Capability Course is an online, on-demand course that dives in deep from the fundamentals, to applications, and a wide range of practical advice and guidance to set up and maintain a valuable SPC program.

Articles – Dennis Craggs has written a seven-article series on process capability in his Big Data & Analytics series.

Articles — A few of short essays by Fred Schenkelberg, Statistical Process Control Overview, Basic Approach to Achieve Process Stability and Supply Chain Process Control and Capability

Tutorials — Statistical Process Control (SPC) and Process Capability set of 17 short tutorials originally written for those preparing for the ASQ CRE exam.

Tolerance Analysis

Tolerances are a common design attribute that conveys an acceptable range of variation for a specific component dimension or value. Setting tolerances based on the knowledge of the expected process variation permits the creation of robust, reliable product.

Here is an abbreviated abstract listing of tolerance-related content on Accendo Reliability.

eBook — Statistical Tolerance Analysis — Basic Introduction includes a bit of background and details on applying the three most common tolerance analysis methods to your design.

Article — Reliability and Tolerance Analysis, Reliability and Root Sum Squared Tolerances, Reliability and Worst Case Analysis, Purpose of Tolerances, Reliability Modeling using Monte Carlo, Consider Variation for Reliable Designs,

Tutorials — Tolerance and worst-cast analysis set of 6 short tutorials originally written for those preparing for the ASQ CRE exam.
