In psychological terms, perception is defined as our recognition and interpretation of sensory information, as well as how we respond to the information.
To understand perception, information technology and literacy instructor Yolanda Williams asks us to think of it “as a process where we take in sensory information from our environment and use that information in order to interact with our environment. Perception allows us to take the sensory information in and make it into something meaningful.”
The 2015 revision of ISO 9001 has debuted with mixed reviews from smaller registrars and suppliers. The question arises: is there going to be any measureable benefit from these changes other than increased income for the ISO bureaucracy? One of the early reasons for change was to align ISO standards with Annex SL. Not sure all the interested parties are excited with this reason.
This month the ASQ/APQC Global State of Quality 2 Research will be released. ASQ and APQC have partnered again to examine the Global State of Quality. As the research did in 2013, the Global State of Quality 2 Research once again aims to further advance the world’s understanding of quality’s impact. The goal of this year’s report is to examine trends that have continued to evolve from the 2013 Discoveries report, as well as identify new trends within the quality industry.
These two choices for bore measurement come into play when close tolerances are the order of the day and speedy, repeatable measurements are required in a production environment. Keeping these requirements in mind, instrument makers usually offer options such as hard chromed bodies or carbide pads and contacts where needed to keep wear at a minimum.
Torque testing is an important quality-control step in nearly every manufacturing sector. Properly testing rotary parts for torque with handheld or automated gages can prevent everything from un-openable bottle caps to loose fasteners. Or, in a grave example, if GM properly acted on failed rotational torque tests of ignition switches in some of its mid-2000s models, 13 lives would have been saved.
The Vickers and Knoop microhardness testing methods have become invaluable for the testing of a variety of parts, which have what can be referred to as “shallow layer hardness.” Such characteristics as surface hardness, thin cross section, coating hardness, and case depth are measured using the microhardness testing methods. These methods also can be useful for selective testing of particular grains or constituents such as those found in powdered metal parts.
Modern manufacturing relies on consistency, and tolerances are tighter than they’ve ever been. Production capabilities are up to the task, and CMM systems help ensure that completed or in-process parts are within tolerance. The real challenge comes when anything goes wrong.
