5 Measurement and Standards General Technical Data and Notes VDI / VDE: a standards specification, similar to ANSI PTB / DKD: European standards institutes, similar to NIST (National Institute of Standards and Technology) Physikalish-Technische Bundesanstalt Deutschen Kalibrierdienst The metal is aged and hardened to maintain accuracy. The aging process is used to eliminate internal stresses and align the molecular polarity of the metal. This is done through a chemical process or by burying the block or plate for a period of time. Rolls Royce used a similar process for their crankshafts and camshafts. A thermal process is used for setting in castellations and spheres. The block or plate is frozen to contract the metal, the castellations or spheres are set in, then it is returned to room temperature at which point heat expansion locks the castellations or spheres into place. SOLUTIONS How it works Periodic monitoring of hand-operated or computer-controlled coordinate measuring machines is carried out on the basis of calibrated mechanical test pieces. Appropriate selection and combination of various test pieces, such as spheres, graduated gage blocks and sphere plates, and their arrangement, make it possible to discover the overall measured volume or particular partial measured volumes corresponding to a typical work piece size and adapt the test to its most important measurement job. The process control is done uniformly in accordance with the nominal data of a test piece. Numeric and graphic evaluation is carried out for each type of test piece with a uniform program and is assessed by trained personnel. Summary characteristic values give an overview of the current level of accuracy and long-term tendencies. In this way the use of coordinate measuring instruments can be optimized and their downtime minimized without high expense.

11 Measurement Measurement and Standards: Standards KOBA-optima KOBA-Optima Optima Artifact for Acceptance Testing and Interval Monitoring of Optical Measuring Instruments Features High short and long-term stability Coefficient of thermal expansion is close to 0 (zero) Easy handling and low weight Conforms to VDI/VDE 2634 Can be calibrated to DKD Non-Contact Systems Contact Systems Step Gages Gage Blocks Technical Data

12 Measurement and Standards: KOBA-optima Technical Data Gage Blocks Step Gages Contact Systems Non-Contact Systems Construction Stable two-part scale body made of CFC tube which is nonsensitive to humidity, with screw joints for best repeatability. Six CFC target holders with 130 openings 10mm diameter precision targets made of glass with chromium layer designed as a blind. Each target has a 1.25mm sight ring surrounded by a hairline of 0.25mm thickness. 15 individual measuring distances, up to 2,588mm long, on a single scale Highest rigidity and low weight of high-module carbon fiber Flexible fastening clips for universal arrangement of scales in the measuring volume. Range of Applications Traceability of measurements performed with photogrammetry or theodolite systems Calibration of photogrammetry or theodolite systems Utilizing photogrammetry and theodolite systems brings many advantages to industry, for example mobility, flexible handling and shortened measuring time. However, the absence of an acceptable calibration artifact has hindered the application of these systems. The KOBA-optima system meets the demands of monitoring these instruments per VDI/VDE guideline 2634 (Acceptance and monitoring of optical 3D-sensor systems). KOBA-optima utilizes the principle of a scale that can be probed optically. A suitable calibration procedure and the necessary calibration structure for the scale were also developed. The KOBA-optima scale system was tested for applicability to the VDI/VDE guidelines in 2000 using a comprehensive study that involved the PTB (Physicalish-Technische Bundesanstalt) and numerous manufacturers and users of photogrammetry and theodolite systems. Results of the study verified the Optima scale systems applicability to the VDI/VDE requirements and also that the system fulfills the demand for an optical physical body traceable to the physical value length. The 2,700mm cylindrical scale body is made of carbon composite material (CFK) and may be separated at the center for transport. The joining ends of the scale body are lapped for consistent, accurate setup. There are six targets located on the neutral fiber of the body; each target has a viewing

13 Measurement and Standards: KOBA-optima Technical Data entry access angle of 130. The clear glass area of each target has a diameter of 10mm. In the center of each of these clear areas is a site ring used for sighting the theodolite system; each site right has an internal diameter of 1.25mm surrounded by a hairline of 0.25mm thickness. The patented KOBA-optima optical scale system has been designed to be a standardized artifact, traceable to a national standard. It is suitable as a calibration standard for optical measuring systems, e.g., acceptance and monitoring inspections. It can also be used as a reference standard for traceability of the particular measuring task to the SI basic unit length specification as defined by the KOBA-optima optical scale system as a physical body. Non-Contact Systems The scales can be easily fixed on tripods, on carrying handles on the object to be measured or onto the object itself by means of fastening clips. Step Gages Certification is provided by the DKD (German calibration service) of the PTB can carry out calibration of the scale. The Measurement Uncertainty of calibrated values is 5µm, which is significantly below that provided by photogrammetry and theodolite systems. As a result, the certifications performed by the KOBA-optima system are suitable as the SI basic unit length according to the demands of the VDI/VDE standard. Contact Systems The KOBA-optima optical scale system provides 15 possible measuring distances per scale with six targets. The combination of measuring distances and scale positioning guarantees a statistically safe measurement. Scales are calibrated on a measuring machine specially modified with a CCD camera to register the targets and with two distance-measuring laser systems for length measurement. The center position of the measuring mark is determined by using an elliptical trace-out program. Gage Blocks Targets that use retro foil as a background guarantee that sufficient light is reflected even if that angle is not favorable for picture taking. Targets that use a white background or background illumination are available as options. 77
