Poka-Yoke for Quality

Shigeo Shingo introduced the concept of poka-yoke (pronounced POH-kah YOH-kay) in 1961, when he was an industrial engineer at Toyota Motor Corp. The initial term was baka-yoke, which means fool proofing.

Monitoring Temperature and Humidity

Monitoring temperature and/or humidity conditions is an essential ingredient of a wide range of quality assurance applications. There are many common methodological errors, however, in ways that this task is approached that either compromise quality standards or add unnecessary time and expense to the monitoring task.

Ultrasonic Material Analysis

Ultrasonic nondestructive testing (NDT) is a versatile technique that can be applied to a variety of material analysis applications. While ultrasonic NDT is perhaps better known in its more common applications for thickness gaging, flaw detection and acoustic imaging, high frequency sound waves also can be used to discriminate and quantify some basic mechanical, structural or compositional properties of solids and liquids.

Metrology Meets Tomography

Computed tomography systems for industrial applications, such as R&D, production and quality, can see inside parts and quantify characteristics normally inaccessible to probing or optical sensors. The same dataset can be used to inspect the structure of material, such as porosity or wall thickness; measure external features; and generate fully surfaced or solid computer-aided design (CAD) models.

Quality 101: Calibration of Machine Tools: Why, What and How

In the past, calibration and compensation have been considered strictly quality issues. Today, adopters acknowledge that calibration and compensation directly relate to substantial improvement in throughput because feed rates can be set higher when machines are known to be in tolerance. As a result, calibration and compensation of computer numerical control (CNC) machine tools is becoming routine, particularly in shops producing parts for the aerospace and medical industries.

Sorting Through Optical Options

Noncontact measurement and inspection is a fundamental practice in many manufacturing environments and quality control labs. Understanding the available options is a continual learning process as the power of video and the PC, as well as other advancements, constantly change and improve. As measuring experts continue to leverage these technology advances, more system choices have emerged.

Six Sigma for Leaders

It’s been more than 10 years since GE’s aggressive adoption of Six Sigma launched a renaissance of quality methods, and some 20 years since Motorola first began minting Black Belts and concentrating on defects. And yet, despite hundreds of documented successes and thousands of committed Six Sigma practitioners, criticism of and skepticism about Six Sigma remains as strong, and probably stronger, than ever.
