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:
The article presents the numerical analysis of the impact of geometry errors on the motion transmission of dual path gearing. The strength calculations of the elements of the drive were made by means of the Finite Elements Method (FEM). The calculations were made for the two-dimensional models of the dual path gearing. In the first place, the drive of the error-free (theoretical) geometry was tested. Next, the modifications of the selected teeth were introduced to the calculation models. The aim of the modifications of the tooth profile was to simulate pitch errors in compliance with the admissible values defined by PN-ISO 1328-1:2015 norm “Cylindrical gears – ISO system of flank tolerance classification”. Finally, all the results were put together for comparison. The obtained results confirm the high irregularity of work gear as a result of errors tooth geometry.

Opis:
A procedure for assessing the properties of a milling machine based on machining tests was presented, with particular emphasis on shape errors and properties of the workpiece surface layer. The selection of an appropriate test-piece and cutting parameters for such a test was discussed. A mathematical formula was also presented, which allows to associate the accuracy of the test-piece with that of the milling machine. The proposed test procedure was verified by evaluating the DMC 1035V Ecoline vertical machining centre.

Opis:
In this paper the influence of oil pockets location on extraction of surface topography features was taken into account. Plateau-honed cylinder liners with additionally added dimples were taken in consideration. The effect of dimples location on the application of various procedures (cylinder fitting procedure, polynomial approximation) for areal form removal was taken into account. It was noticed that application of 3rd (or greater) degree of the polynomials can caused false estimation of reference plane; extraction of surface topography features by polynomial approximation cannot provide good results when the distance between dimples is too small. For two-process surfaces (plateau-honed cylindrical elements containing wide and deep valleys) the digital filtering was proposed. Application of robust techniques (robust Gaussian regression filter) allowed for areal form removal improvement. However, some of the wide dimples were distorted when the dimple-to-edge distance was too small (smaller than filter bandwidth value).

Opis:
This paper presents the evaluation of the influence of the feedmotion speed on the value of selected geometric errors of CNC lathe CTX 310 eco by DMG, indentified by QC 20 Ballbar system. Diagnostically evaluated were: the deviation of the axis squareness, reversal spike, and backlash. These errors determine the forming of the dimensional and shape accuracy of a machine tool. The article discusses the process of the CNC diagnostic test, the diagnostic evaluation and formulates guidelines on further CNC operation. The results of measurements were presented in tables and diagrams.

Opis:
The eccentric rolling transmission consists of rolling bearings mounted eccentrically on the input shaft, cooperating with cam wheels, which are mounted on the output shaft. The aim of this paper was to determine the sensitivity of the transmission to the manufacturing errors of the cam wheel. Two methods of cam wheels milling using a universal CNC machining center were proposed. The measurements of manufactured wheels were performed using a blue light 3D scanner, which allowed the determination of geometric dimensions and deviations from nominal geometry. The experimental research of the eccentric rolling transmission prototype equipped with manufactured cam wheels was conducted, measuring the torque on the gear shafts as a function of its angular position. On the basis of the obtained results, the impact of manufacturing errors on the operation of the transmission unit was examined, especially in terms of torque and efficiency. It was indicated that the machining using ball nose end mill ensures sufficient accuracy of the cam wheels.
