Original abstract
The present article is dedicated to the identification and interpretation of geometric errors of CNC machine tools. Identification of geometric errors plays a large role in the construction of the so-called "Error maps". These maps can be used to describe the behaviour of the machine in the workspace without load or under conditions of finishing operations. Interpreting the error maps represents a tool to check the state of the machine for the user and to offer the important information for the machine manufacturer. From this information it is possible to identify "weak" points of the machine. Simultaneously, the information on the geometrical errors is used to compensate for machine tools. When constructing the maps, a selection of the measuring device and ambient conditions plays an important role. The paper focuses on the use of measuring equipment LaserTRACER and construction of the error map for the workspace of horizontal three-axis milling machine. It also describes the options of how to monitor the workspace of the machine and their mutual evaluation.

Tento článek se zaměřuje na identifikaci a interpretaci geometrických chyb CNC obráběcích strojů. Identifikace geometrických chyb hraje velkou roli při budování tzv "map chyba". Tyto mapy lze použít k popisu chování stroje v pracovním prostoru bez zatížení nebo za podmínek dokončovacích operací. Interpretace chybové mapy představuje nástroj pro kontrolu stavu stroj pro uživatele a nabídnout důležité informace pro výrobce stroje. Z těchto informací je možné identifikovat "slabá" místa stroje. Současně, informace o geometrických chyb se používá pro kompenzaci pro obráběcí stroje. Při konstrukci map, výběr měřicího přístroje a okolních podmínkách hraje důležitou roli. Článek se zaměřuje na využití měřicích zařízení LaserTRACER a konstrukce chyb mapy na pracovní ploše horizontální tříosého frézky. Dále popisuje možnosti, jak sledovat pracovního prostoru stroje a jejich vzájemné hodnocení.
