Abstract

The accuracy of machmed worlcpieces represents the main criterion for every workshop. One of the most important contributing factors is the geometric accuracy of the machne tool. Machines are nowadays equipped with control systems enabling engineers to perform various types of compensations. In the case of geometric compensations the question stands whether to apply only axial compensations or also inter-axial compensations. The article shows the differences in the geometric accuracy of a vertical machining center equipped with linear motor drives measured in three different cases. The machne tool was checked by the classical method according to the IS0 230-2 standard in different positions within the worlung volume in each axis and also by th
