Proper fixturing addresses several key parts of quality: It ensures that inspected parts remain in a repeatable and reproducible orientation on a measuring device.

Today’s manufactured components are more multifaceted than ever, requiring more parts, additional updates to those parts and ever tighter tolerances. 

Hitachi High-Tech Analytical Science has expanded its plating and coatings analysis range with the launch of the breakaway FT230.

Hexagon calibrates service offering to meet advanced manufacturing needs in Canada.

America Makes and the American National Standards Institute (ANSI) announced the availability of a Gaps Progress Report tracking efforts by standards developing organizations (SDOs) and others to address the gaps identified in the Standardization Roadmap for Additive Manufacturing (version 2.0, June 2018), published by the America Makes and ANSI Additive Manufacturing Standardization Collaborative (AMSC).

Measurement and inspection standards are traditionally updated on a regular schedule. However, the form measurement standard for out of roundness, B89.3.1, has not been updated since its initial release in 1972, and is no longer an active standard available through ANSI.

The journey to create a standard is very interesting and requires attention to detail. Before a standard can be created one must develop the need and benefits for its development.

“Measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the stand deviation."

Indicators have evolved and many different types have been introduced such that there now exists a whole world of indicators.

A standard is a document established by consensus and approved by a recognized bodythat provides – for common and repeated use – rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context.
