A simple yet comprehensive approach to the testing of machine tools with arbitrary axis configurations

The standards for machine tool testing have developed historically with the advancement of machine tool technology. Due to the high number of machine types and possible configurations industry increasingly suffers from the complexity of the test procedures described. This paper introduces a concept of unified specifications and test procedures that can indicate the geometric accuracy of an individual machine to generate an accurate part, independent of the machine tool configuration. The paper presents the concept and verifies it by comparison measurements with different instruments.
