Geometric Accuracy of Large Machine Tools [PDF]
Acta Mechanica Slovaca, 2020 This article describes the issue of geometric accuracy of large machine tools. The operation and maintenance of large CNC machine tools is usually affected by a number of aspects related to large workpieces and spaces at the machine installation site. It is the size of the working space and the large dimensions of the production halls that very often ...
