• Influence and development of new kinematic systems in flat surface lapping

  Publikacja

  • A. Barylski
  • N. Piotrowski

  - Rok 2015

  The face grinding and lapping technology is widely used in the field of the precise and ultraprecise manufacturing. It has become an indispensable technology in the manufacture of many parts. An absence of material restrictions allows machining both metal and non-metallic materials, including technical ceramics [1]. Nowadays there are mainly two kinematic systems in lapping machines [2]. The machining plane-parallel surfaces is...

• New kinematic systems in single-sided lapping and their influence on lap wear

  Publikacja

  • A. Barylski
  • N. Piotrowski

  - Applied Mechanics and Materials - Rok 2016

  Previous studies on one-sided lapping allow to state that not only parameters of lapping elements (i.e. properties of workpiece, abrasive grains and lapping plate) impact on a lapping efficiency. Influential are also kinematics and dynamics of the process. It is crucial to control an average velocity of lapping (v), a distribution of tangential acceleration (at), a nominal pressure (p), a lapping time (t) and disposal of workpiece...

  • M. Majewski
  • Z. Budniak
  • J. Ponomarenkow

  - Materials - Rok 2021

  This paper presents the fundamentals of the design and applications of new worm gear drive solutions, which enable the minimisation of backlash and are characterised by higher kinematic accuracy. Different types of worm surfaces are briefly outlined. Technological problems concerning the principles of achieving a high degree of precision in machining are also described. Special attention is paid to the shaping of conical helical...

• Multi-criteria Robot Selection Problem for an Automated Single-Sided Lapping System

  Publikacja

  • N. Piotrowski
  • A. Barylski

  - Rok 2016

  Flat lapping is a crucial process in a number of precision manufacturing technologies. Its aim is to achieve extremely high flatness of the workpiece. Single-sided lapping machines have usually standard kinematic systems and are used in conjunction with conditioning rings, which are set properly be-tween the center and the periphery of the lapping plate. In this paper, instead of conventional single-side lapping machine, an automated...

• Degradation of Kinematic PPP of GNSS Stations in Central Europe Caused by Medium-Scale Traveling Ionospheric Disturbances During the St. Patrick’s Day 2015 Geomagnetic Storm

  Publikacja

  • M. Poniatowski
  • G. Nykiel

  - Remote Sensing - Rok 2020

  In solar cycle 24, the strongest geomagnetic storm took place on March 17, 2015, when the geomagnetic activity index was as high as -223 nT. To verify the impact that the storm had on the Global Navigation Satellite System (GNSS)’s positioning accuracy and precision, we used 30-s observations from 15 reference stations located in Central Europe. For each of them, we applied kinematic precise point positioning (PPP) using gLAB software...

• Evaluation of RTKLIB's Positioning Accuracy Using low-cost GNSS Receiver and ASG-EUPOS

  Publikacja

  • B. Wiśniewski
  • K. Bruniecki
  • M. Moszyński

  - TransNav - The International Journal on Marine Navigation and Safety of Sea Transportation - Rok 2013

  The paper focuses on a comparison of different positioning methods provided by free and open source software (FOSS) package called RTKLIB. The RTKLIB supports real‐time and post‐processed positioning. The most important modes of operation tested by the authors are Kinematic, Static, Fixed and Precise Point Positioning (PPP). The data for evaluation were obtained from low‐cost Global Navigation Satellite System (GNSS) receiver....

• EVALUATION OF THE SEMIVARIOGRAM SELECTION ON THE KRIGING INTERPOLATION

  Publikacja

  • W. Błaszczak-bąk
  • K. Pajak
  • A. Sobieraj-Żłobińska

  - Rok 2015

  The aim of the paper is to present the possibilities of geostatistical interpolation kriging method using in the process of generating digital terrain models (DTM). The source of data is a direct measurements realized with a precision GNSS positioning kinematic measurement technique RTN. Kriging algorithm was analysed, especially in the meaning of a semivariogram every step. Theoretical semivariogram selection influence on the...
