The Tetronom and Oktonom that consists of tetronom single bars and ball targets. Due to its three-dimensional construction, 3D measuring instruments and machine tools can be tested very efficiently. In only one setup, the probing deviations as well as the scale and perpendicularity conditions can be checked. Furthermore, it allows for direct comparison of different measuring systems.
Targets for the tetronom
Targets can be made of stainless steel or ceramic or can be theodolite, laser tracker and retro-reflective targets as well as blasted or coated balls. The standard ball diameter is 38.1 mm (1.5“, all targets) and 50 mm (1.96“, except theodolite, laser tracker and retroreflective targets). This allows tactile as well as optical measurements. The targets are characterized by their extremely accurate manufacturing.
Areas of application
The tetronom and Oktonom are very appropriate for rapid and reliable periodic supervising as well as measurement system analysis and testing with regard to the temperature behavior. Due to its shape and materials used, the tetronom fulfils all requirements for artefacts according to the VDI/VDE guidelines 2617 and 2634 as well as to DIN EN ISO 10360.
