About Koordinaten-Messtechnik Iserlohn
Koordinaten-Messtechnik Iserlohn GmbH (KMI) is a service provider for engineering services in the field of 3D coordinate metrology. The company was spun off in 2004 through a management buy-out from the Iserlohn Institute for Plastics Machinery and has a fully climate-controlled 200-square-metre measuring laboratory as well as training rooms in Iserlohn. Its range of services includes tactile measurements with coordinate measuring machines (CMM), non-contact optical metrology with image processing, 3D digitisation using fringe projection (point clouds, nominal-actual comparison, reverse engineering), initial sample inspection reports, series measurement with statistical evaluation, CAD measurement of free-form surfaces, geometrical tolerances (GD&T), contour and roughness measurement, computed tomography (ICT), tool measurement, gauge concepts and surface back-transformation. In addition, KMI develops its own clamping system (KSystem) and offers workshops and training courses on 3D metrology. The laboratory is accredited to DIN EN ISO/IEC 17025:2018 by DAkkS. Customers come from industries such as automotive and supply, plastics processing, medical technology, aerospace, mechanical engineering as well as sanitary fittings and toy industries; the customer base extends nationwide from Lübeck to Munich.

Processes and Measuring Systems
Tactile coordinate metrology
Dimensional, form and surface measurement of workpieces with switching or measuring probe systems (Wenzel LH87/LH108).
Optical metrology with image processing
Non-contact measurement of the smallest components in transmitted or reflected light (OGP Flash 200, Hexagon Optiv Performance 443 Dual Z).
3D surface scan (fringe projection)
High-precision capture of complex shapes as a point cloud for nominal-actual comparison and reverse engineering (GOM Atos Compact Scan 12M, Steinbichler Comet 5).
Computed tomography
Non-destructive interior and exterior testing of components.
CAD measurement (free-form surfaces)
Measurement, evaluation and assessment of profile and line form tolerances on functionally relevant areas up to single-point representation for toolmaking.
Series measurement and statistics
Single-part and series measurement with statistical evaluation and series monitoring by sampling.
Initial sample inspection report
Traceable documentation of all measured values in accordance with DIN EN ISO/IEC 17025:2018, also using customers' own report templates.
KSystem clamping system
In-house developed clamping technology for repeatable, precise positioning of components in optical and tactile metrology.
