Abstract: This paper aims at the accuracy control method in the machining of capsule micro holes with single point diamond turning technology. Firstly, a error model of capsule micro holes machining is established and the effect of each error component on micro holes dimension accuracy is theoretically analyzed. Secondly, according to the error analysis results, an accuracy control method is introduced, in which diamond tool step feeding method is adopted for micro holes accuracy control. Finally, GDP capsule micro holes machining experiments are carried out on ultra-precision machine. According to the results, the dimension error and roundness error of micro hole reduce 70.7% and 87.5% separately, which verifies the validity of the accuracy control method in this paper.-
