e-Learning: AS13006 – Process control methods (SPC)

Programme overview

TEC’s e-Learning (on-line training) course covers all of the requirements of AS13006 Process Control Methods using tests, quizzes, case studies and practical exercises. The objective is to qualify practitioners who will be ‘subject experts’ able to understand the theory and be capable of implementing capability studies and process control charts (SPC – Statistical Process Control) – and the training of operators.

This course is designed for Quality Engineers, Continual Improvement Practitioners, Six Sigma ‘Belts’ and others involved in process control implementation and/or AAs/AEAs conducting third-party audits involving process control selection and usage.

TEC are an approved AESQ Training Provider, and this e-Learning course is based on TEC’s PROBITAS Authentication approved course

The e-Learning course includes sessions on basic statistical analysis and graphs, ‘fast-track’ SPC setup using Minitab® and the "Formulae" and "Table of constants" as well as a detailed exploration of the theoretical basis of Control Charts.

In addition to covering AS13006 requirements, particular attention is given to the selection and use of practical variables and attributes SPC in the aerospace and defence sectors in which low volumes, complex products and high product mixes are the norm! The role of Taguchi’s Loss Function is addressed to underline the importance of continual process improvement. Deployment of error/mistake proofing devices is explained to prevent operator/process mistakes occurring in the first place.

The relationship between the AS9145, AS9103, AS13003, AS13004 and SAE J1739 standards are identified and explained – with particular reference to Control plans, PFMEAs and Measurement Systems Analysis (GR&R).

The benefits of SPC are emphasised and 'road-blocks' to deployment are identified and countered!
