Metrology, analysis and technical consulting — from initial survey to documented correction.
Geometric capture of machines, assemblies and complete plants as a sound basis for alignment, assessment and optimisation.
Analysis and correction of reference axes, flatness, parallelism, angles and spatial relationships — directly at the plant.
Geometry as a tool for the systematic investigation of tracking issues, functional deviations and unstable processes.
High-precision measurement in large volumes, also under real production conditions and with neighbouring lines running.
Technical support for conversions, relocations, commissioning and special tasks — with a clear view of on-site feasibility.
Physics-based assessment of technical systems and structured derivation of sound technical measures.
All figures refer by way of example to a Leica Absolute Tracker AT401 and are transferable in order of magnitude to other 3D laser tracker models from various manufacturers.
Measuring range in diameter, corresponding to a 160 m radius (manufacturer's specification).
Measurement accuracy (MPE). Repeatability: ±7.5 µm + 3 µm/m. Absolute distance: ±10 µm.
Practical working radius under industrial conditions, corresponding to around 220 m in diameter.
Measurement distance range in which typical plant surveys take place.
In practice this means: at short range the measurement deviation lies within hundredths of a millimetre — 0.075 mm over 10 m of measurement distance. The 0.1 mm mark is passed at about 14 m, so the tenth-of-a-millimetre range begins from roughly 15 to 20 metres: 0.135 mm over 20 m and 0.375 mm over 60 m. Up to the limit of its range the deviation stays within the sub-millimetre range.
Manufacturer's specifications per ASME B89.4.19-2006 using a Leica 1.5-inch Red Ring Reflector. The accuracy actually achievable also depends on thermal drift, vibration and the number of station changes.
Four steps that build on one another in this order.
Which problem is to be solved, what statement is needed, and what accuracy is actually required.
Setting up the reference system and capturing geometry under actual operating conditions.
Nominal/actual comparison, assessment of deviations and physical interpretation of results.
Traceable documentation with concrete correction values and a recommendation for implementation.
Typical time on site: a single opening press is surveyed in two to five measuring days, four crane runways in about two to four days. For double belt presses the range runs from two days to several weeks, depending on scope. Metrological support during first installations naturally takes longer than a control survey.
Systems and software in use.
Instrument typically in use: Leica Absolute Tracker AT401 with absolute distance meter, inclination sensor and integrated environmental monitoring. Beyond that, experience with Leica and FARO systems in continuous industrial use.
Professional 3D metrology software for evaluation, network adjustment, best fit and nominal/actual comparison against drawing or CAD model.
Measurement reports with reference system, uncertainty, deviations and correction values.
Area of operation: journeys of up to about three hours are possible without an overnight stay, or by arrangement — this includes Vienna, Lower and Upper Austria, Salzburg, Burgenland, Styria as well as neighbouring regions in southern Germany, the Czech Republic, Slovakia and Hungary. Beyond that, assignments across Europe and worldwide by arrangement; past projects have led to Portugal, Italy, Hungary, Mexico and Peru, among others.
A brief description of the plant and the observed problem is usually enough for an initial assessment.
