Abstract
Conventional five-axis machining centers with a tilting rotary table have two rotary axes parallel to linear axes. Recently, some machining centres with an inclined A-axis are developed. However, there is no method for measuring the deviations inherent to this type of machines. A new measurement method is proposed as well as the identification method. It is found that the inherent deviations can be identified by carrying out simultaneous three-axis motion for the C-axis and simultaneous four-axis motion for the inclined A-axis.
