In this paper, a comprehensive architecture of test-bed for machining and errors prediction Virtual Machining and Measuring Cell (VMMC) is built which can simulate the machining process, measuring process, predict the machining errors and so on.
Considering the desired tolerance envelope of the part, an error decomposition technique is developed to model machining errors caused by the systematic and non-systematic errors in the machine tool.
To compensate for machining errors, a tuning method has been devised to achieve desired RF parameters for the structure, which has been qualified by the successful tuning of a 7-cell buncher to π mode frequency of 2856 MHz with field flatness <3% and RF coupling coefficient close to unity.
