Opis:: LaserTracer (LT) systems are the most sophisticated and accurate laser tracking devices. They are mainly used for correction of geometrical errors of machine tools and coordinate measuring machines. This process is about four times faster than standard methods based on usage of laser interferometers. The methodology of LaserTracer usage to correction of geometrical errors, including presentation of this system, multilateration method and software that was used are described in details in this paper.

CMM kinematics
Opis:: CMMs accuracy depend on a number of factors. In spite of using various methods for CMM correction, the differences can be observed in the metrological capability be¬tween the areas in the measuring volume of CMM. Authors attempted to estimate the impact of one of potential CMM accuracy influencing factors, a CMM Z-axis position during measurement, on measurement result. This article presents performed experi¬ments and obtained results.

Tematy:: residual errors
CMM correction
Opis:: In case of coordinate machines that use CAA correction matrix, the issue of kine¬matic errors analysis may be based on the determination of residual error distribu¬tion. Temperature changes have an impact on CMM kinematic structure, which may cause the differences in the map of residual errors. As for today, the residual errors were analysed only for the reference temperature. No research was undertaken on the residual errors changes depending on the temperature variations. This paper presents the experiment aimed at residual errors analysis and resulting errors distributions for different temperatures.

Opis:: Biologicznie aktywne i medycznie użyteczne substancje naturalne pochodzenia roślinnego występują na ogół w wieloskładnikowych grupach związków o podobnych właściwościach chemicznych i fizykochemicznych, co znacznie utrudnia ich izolację, a zwłaszcza oczyszczanie. Lecznicze saponiny kasztanowca, tradycyjnie stosowane w medycynie w postaci złożonej mieszaniny (escyna), są przykładem sytuacji w której właściwości farmakologiczne indywidualnych komponentów. Zaprezentowano jedno z możliwych rozwiązań tego problemu na drodze transformacji chemicznych dostępnego surowca, które umożliwiają otrzymanie kluczowego pentacyklicznego triterpenu – protoescygeniny (PES) w stanie wysokiej czystości chemicznej, w procesie realizowanym w pilotowej skali technicznej. Wskazano możliwości zastosowania PES jako dogodnego półproduktu do syntez saponinomimetyków o zróżnicowanych typach struktury.
Biologically active and medically useful natural substances of vegetable origin usually occur in multi-component groups of compounds with similar chemical and physical properties, which significantly inhibit their isolation, and in particular their purification. Therapeutic chestnut saponins, traditionally used in medicine in the form of complex mixture (aescin), are the example of situation where pharmacological properties of individual components. One of the solutions to this issue was presented, based on chemical transformation of available raw material, allowing production of key pentacyclical triterpene - protoescigenin (PES) of high chemical purity, in the process implemented on pilot scale. Possibilities of using PES as a convenient semi-finished product fin the synthesis of mimetic saponins with varying structures.

Opis:: The five-axis measuring systems are one of the most modern inventions in coordinate measuring technique. They are capable of performing measurements using only the rotary pairs present in their kinematic structure. This possibility is very useful because it may cause significant reduction of total measurement time and costs. However, it was noted that high values of measured workpiece’s form errors may cause significant reduction of the accuracy of a five-axis measuring system. The investigation on the relation between these two parameters was conducted in this paper and possible reasons of decrease in measurement accuracy was discussed on the example of measurements of workpieces with form errors ranging from 0,5 to 1,7 millimetre.

Opis:: One of the factors affecting the accuracy of Coordinate Measuring Systems is hysteresis of a probe head. It is important especially in case of touch trigger probes and should be taken into account during the determination of probing strategy. In this article, the authors try to assess how this phenomenon affects the accuracy of five axis coordinate systems which utilize articulating probe head. Such systems allow to measure point coordinates using rotary movements of the head what introduces changes to the probing process. The experiments presented in this paper are based on multiple measurements of the reference elements such as gauge blocks and standard ring.

Opis:: The 5-axis systems, especially those that use in their kinematic chain both prismatic joints and revolute kinematic pairs are gaining popularity in many scientific disciplines with manufacturing, metrology and robotics at the forefront. This is therefore important to undertake research aiming in identification of sources of inaccuracies in their functioning and investigation on possibility of eliminating or compensating them. A significant impact on 5-axis kinematic structures accuracy may be assigned to parameters associated with the stabilization of the machine position and angular position, such as position stabilization time, position overshoot and drift of positioning accuracy. These parameters are well described in ISO 9283 standard related to performance criteria and test methods for industrial robots. The methodology presented in this standard is adapted for testing the impact of mentioned parameters for functioning of 5-axis kinematic structures other than industrial robots, which mainly include five-axis coordinate measuring systems and machine tools. A series of experiments performed on five-axis coordinate measuring system is presented in this paper, their results are assessed in a quantitative manner and basing on them a general algorithm for assessing the significance of impact of position stabilization parameters on functioning of the manipulator is proposed.

Opis:: The measurements of solids of revolution are one of the most common task in industrial practice. Therefore it is not surprising, that new solutions dedicated to improve accuracy and acceleration of measurements of rotational components are emerging. In this group, the new generation of articulating probing systems (with ability of continuous indexation) is worth mentioning. These probing devices combined with standard CMM forms the five-axis coordinate system. Such solution results in measurements acceleration and also improve measurement repeatability. Studies on this type of probing systems proved that their accuracy depends strongly on the angular orientation of probing system used during measurement. Therefore authors developed model that allows simulation of probing system errors for any orientation. This article describes an attempt to use the model to find the configuration of the probing system that would provide the highest accuracy for rotational elements measurements. The simulation results are compared to the real measurements of standard elements performed on five axis measuring system. Described prediction method could have a beneficial effect on improving the accuracy of measurements and, as a result, on reducing production costs by minimizing the risk of erroneous decision on the conformity of products with their geometric specifications.
