The fundamentals and contemporary status of topographic mapping of Ukraine’s territory has been studied. Prior to declaration of Ukraine’s independence, its territory was covered with 1:10,000 to 1:1,000,000 scale topographic maps made by sub-divisions of the Chief Department of Geodesy and Cartography affiliated with the Council of Ministers of the USSR (GUGK USSR) and sub-divisions of the Military Topographic Service (MTS) of the USSR Armed Forces. Topographic mapping related cooperation between these institutions has been described. Topographic study of Ukraine’s territory as at 1991 has been subject to close analysis, with due consideration of the coordinate systems used for topographic maps. During the first years after Ukraine’s independence declaration topographic maps in Ukraine were made according to the previously effective Soviet instructions in the 1942 coordinate systems and 1977 Baltic height system. Since mid 1990s, Ukraine enjoyed transition from analog technology of making topographic maps to digital one. The contemporary legal and statutory support of topographic mapping in Ukraine has been studied; the implementation since 1 January 2007 of the UCS-2000 national geodetic reference coordinate system and the height system measurement works have been analyzed. Focus has been made on obsolescence of information of contemporary topographic maps and on extensive deprivation of secrecy for topographic maps in 2000s. Critical for the development of topographic mapping in Ukraine is now the Law of Ukraine “On National Geospatial Data Infrastructure” adopted in 2020. The Topographic Service of the Armed Forces (TS AF) of Ukraine carried out big scopes of works to update the topographic maps related to Russia’s military operations against Ukraine.

The article presents the methodology to estimate the operator influence on measurements performed with a coordinate measuring arm. The research was based on the R&R analysis, adapted to the specifics of redundant devices such as ACMM (selection of a test object difficult to measure). The method provides for measurements by three operators, who measure ten parts in two or three samples (measurement data developed in the article relate to the three measurements of holes). The methodology is designed to identify which operator has the best predisposition to perform measurements (generates the smallest measurement errors). Statistica software was used to analyse and visualize measurement data.

W artykule przeanalizowano dwa zagadnienia związane z obliczaniem współrzędnych przesunięć zespołów obrabiarkowych. Współrzędne te służą programiście do programowania operacji technologicznych na obrabiarkach sterowanych numerycznie (OSN). Pierwsze zagadnienie dotyczy obliczania wymiaru nastawnego, którego nie ma na rysunku konstrukcyjnym, drugie odnosi się do symetryzacji wymiarów tolerowanych niesymetrycznie. Warunki techniczne prawidłowego obliczania współrzędnych przesunięć i symetryzacji zostały opisane wzorami analitycznymi, co jest ważne w teorii technologii maszyn.

In the article the two issues connected with coordinates calculation of machine tools assemblies transfers were analyzed. These coordinates serve the programmer to program the technologic 'operations on the numerically controlled machine tools. The first issue considers the calculation of coordinate's tolerated dimension, which is not on the engineering drawing. The second one considers the calculation of asymmetrically tolerated dimensions. These two above issues were described with analytical formulas, which is very important in the production technology.
