Abstract This paper presents a comparison of different techniques to capture nominal data for its use in later verification and kinematic parameter identification procedures articulated arm coordinate measuring machines (AACMM). By using four probing systems (passive spherical probe, active self-centering passive probe probe) the accuracy repeatability captured points has been evaluated by comparing these materialized ball-bar gauge distributed several positions measurement volume. Then, it...

This article presents a self-calibration procedure and the experimental results for geometrical characterisation of 2D laser system operating along large working range (50 mm × 50 mm) with submicrometre uncertainty. Its purpose is to correct geometric errors setup generated when positioning two heads plane mirrors used as reflectors. The non-calibrated artefact in this commercial grid encoder that also measuring instrument. Therefore, allows determination encoder, including its squareness...

An electric model for electrolysis cells used in copper electrowinning processes is developed. It applied to the analysis of cells, using series configurations bipolar floating electrodes. This technology has been several fields electrochemistry, but not yet by industry. Its main advantage that, same production, cell requires a much lower DC current, as compared conventional which use parallel configuration unipolar feature allows it be supplied from modular and compact PWM rectifier instead...

The nanotechnology field has been developing strongly in recent years and ultra-precision measuring systems are nowadays required. A new two-dimensional moving platform with 50x50 mm range of travel, nanometer resolution sub micrometer accuracy is being designed by the authors order to be integrated an Atomic Force Microscope (AFM). In this work definition, design experimental characterization a homing sensor system for 2D presented. will allow generation absolute reference on X-Y axis θz,...

La metodología Lean Six Sigma es popularmente conocida en el giro industrial como una forma de reducir la variación los procesos productivos, donde, mediante uso herramientas las filosofías Esbelta y Seis Sigma, se busca mejorar calidad productos o servicios al menor coste posible. Si bien existen diferentes estrategias, ha vuelto sumamente llamativa últimos años por eficiencia magnitud sus resultados. En este trabajo presenta aplicación dicha empresa dedicada a fabricación artículos...

This paper is a contribution to the electric modeling of electrochemical cells. Specifically, cells for new copper electrowinning process, which uses bipolar electrodes, are studied. Electrowinning used together with solvent extraction and has gained great importance, due its significant cost environmental advantages, as compared other reduction methods. Current use unipolar electrodes connected electrically in parallel. Instead, series. They also called floating, because they not...

The demand of faster and reliable measuring tasks for the control quality assurance modern production systems creates new challenges field coordinate metrology. Thus, search solutions in metrology development existing ones that respond to industry’s demands still persists. An example such are portable machines (PCMMs), which use industry has considerably increased during last years, mostly due their flexibility accomplishing in-line as well reduced costs operational advantage compared...

The utilization of 2D non‐contact sensors for measuring displacements is a more and used alternative the development several degrees freedom precision systems. Inside this group sensors, optoelectronic devices such as CCDs (Charge‐Coupled Devices) or PSDs (Position Sensitive Detectors) are included. an adequate option when economical cost needs to be decreased. Nevertheless, characterizing adequately correcting error those needed in order achieve expected accuracy. A possible technique carry...
