For surface texture measurements to be most effective, results must predict functionality. Morphological filters allow us to quantify functions such as appearance, sealing ability, and wear resistance. Read our article on this topic that appeared in Aerospace Manufacturing and Design Magazine, July 2019.
This tutorial discusses a step-by-step and visual approach to surface texture measurement. The process, which is the basis of the OmniSurf3D software, allows designers, managers, process engineers and lab staff to explore, understand and communicate surface texture. By providing a common language for surface texture analysis, OmniSurf3D helps everyone involved to improve component performance.
This presentation addresses one of today's most costly concerns in applied dimensional metrology: correlation. The disagreement is not often predictable. To address these topics, several aspects of measurement correlation will be explored including wavelengths, uncertainty, instrument performance and "instrument overlap".
The 2004 International Dimensional Workshop was themed "Dimensional Metrology for Functional Control". This keynote address of the same title discusses a 4th generation approach to dimensional measurement whereby instead of reporting dimensional results, the measurands are those of functional attributes. Examples of simulating product functionality within existing dimensional measuring systems are presented along with methodologies for for extending this approach.
The topics of filtering and fitting as well as their relationships were presented in a paper at the 2002 International Dimensional Workshop. The presentation included new filtering methods and example applications of these methods. In addition, methods for incorporating new analysis methods into existing instrumentation were discussed.
Cylinder bores require some of the most critical surfaces in terms of functionality. They require a balance between: smooth - for the sake of reduced friction; and rough - for lubrication retention and/or debris tolerance. This presentation addresses some of the specification, manufacture and measurement concerns related to these critical surfaces.
This presentation looked at the difficulties and possible solutions for working in the areas of measurement where surface metrology and dimensional metrology overlap. Topics include: instrumentation evolution, filtering and processing of data, functional measurement for difficult features, and metrology in the information age.
At this year's SME Honing Conference, Digital Metrology Solutions presented a paper addressing the "value of measurement". Given that the audience was primarily made up of manufacturing professionals, this presentation focussed on the proper use of metrology as a "tool" at their disposal. The topics ranged from "why measure?" to a "gentle introduction to measurement uncertainty".
Digital Metrology presented a paper at the 2000 International Dimensional Workshop regarding the over "unification" that it taking place within the field of metrology. More specifically, the historical distinction between "surface metrology" and "dimensional metrology" seems to be going away. Several technical, and economic implications are explored in this context and some general principles are presented regarding the future directions for metrology.
