DMIS 5.3 Standard Now Available
BURLESON, TX — A new version of the Dimensional Measuring Interface Standard (DMIS) version 5.3 has been approved as an American National Standard by ANSI (American National Standards Institute).
Under the auspices of the Dimensional Metrology Standard Consortium (DMSC, Inc.) this new version of DMIS contains all capabilities of previous versions of DMIS, as well as corrected errors, recent updates, and new enhancements. DMIS 5.3 is a more comprehensive standard representing a response to user requests, industry needs, and technology advances in the field of Metrology.
What is DMIS?
Although there are many commercial products based upon DMIS, it is not a commercial software product. DMIS is an American National Standard as well as an ISO Standard. DMIS defines a neutral language format for communication between information systems and dimensional measurement equipment (DME), and it is very likely the most widely used metrology standard in the world today. DMIS can perform as an execution language for measurement part programs as well as provide an exchange format for metrology data such as features, tolerances, motions and measurement results.
DMIS conveys the product and equipment definitions along with the process and reporting information necessary to perform dimensional measurements that employ coordinate metrology. DMIS contains product definitions for nominal features, feature constructions, dimensional and geometric tolerances, functional datums, and part coordinate systems. DMIS also associates and designates the criticality of key characteristics of tolerance(s) with feature(s). This standard communicates equipment definitions for various measurement sensors, measurement resources, and machine parameters. DMIS instructs the DME and/or sensor's motions and touch probing or scanning measurements for product acceptance or verification and for manufacturing process validation and control. Furthermore, DMIS guides the analysis of coordinate data to report and tag measurement results that ascertain product/process quality.
The latest version DMIS (5.3) contains QPId’s to enhance its capabilities in concert with the QIF suite of Standards. QPId refers to "QIF Persistent ID." It is the QIF implementation of a universally unique identifier UUID (also called a Globally unique identifier GUID) used to uniquely identify a whole QIF document, a subsection of a QIF document, or single QIF entity like a feature or a characteristic.
Mechanisms for Change
Mechanisms for change to the DMIS standard include active participation in the DMSC as a supporting consortium member, OR the submission of Standard Improvement Requests (SIR) through the DMSC SIR website, www.dmsc-standards.info.
