Standards and guidelines are significant success factors for the competitiveness of a company. Learn more about new standards and guidelines for roughness measurement and cutting edge evaluation that are currently in development.
Standardization body: Technical committee 213 Dimensional and geometrical product specifications and verification
Standardization in the field of geometrical product specifications (GPS), i.e. macro- and microgeometry specifications covering dimensional and geometrical tolerancing, surface properties and the related verification principles, measuring equipment and calibration requirements including the uncertainty of dimensional and geometrical measurement. The standardization includes the basic layout and explanation of drawing indications (symbols).
Current standards for measuring profile roughness include ISO 4287 and ISO 4288. A new standard is aimed at combining and extending existing guidelines and solving existing problems for the user. ISO 21920 for this purpose deals with the surface properties in the technical product documentation and includes the following:
A new draft of ISO 25178 is currently being developed for area-based roughness measurements. This standard specifies terms, definitions and parameters for determining the surface texture using area-based measurement methods. Most parts of the new standard have already been completed, so that at present only the final touches are being made. Thus, among other things, the documents that determine the calibration of optical, area-based measuring instruments are currently being processed.
ISO/NP 25178 includes among others

Planned guidelines (in development):
The defined edge geometry of cutting tools is a crucial factor for the improvement of tool life and processing quality. In order to enhance the standardization of cutting edge measurement, Bruker Alicona is currently developing new standards with the Association of German Engineers (VDI) and partners in industry and research. Consequently, these standards are going to result in a global new EN ISO standard for cutting edge measurement. There are numerous fields of application for the use of cutting edges in the manufacturing technology. However, a comparable measurement of edges and edge parameters has not been assured yet. As one of the international leading producers of optical 3D metrology, Bruker Alicona has sensed the need for standardization of cutting-edge measurement. Thus, Bruker Alicona contacted the Association of German Engineers (VDI), the National Metrology Institute PTB and leading research institutions.
Bruker Alicona's proposal to develop new guidelines for quality assurance and thus improving reproducibility, comparability and traceability of measuring results, was well received by industry and research. The focus of the joint venture is the creation of new standards for the measurement and evaluation of cutting edges and radii. The aim is to unify the description of cutting tools as well as the methods for measuring cutting edges. Establishing these guidelines shall determine the different functional requirements for edges and radii considering the needs of the industry. The new standards for cutting edges are intended to help users in the interpretation of their measurements. Furthermore, it is thought to enhance reproducibility of measurement results as well as the comparability of measurements and measurement devices of different manufacturers. Consequently, these standards are going to result in a global new EN ISO standard for cutting edge measurement.
