| Abstract: | Having researched the formation mechanism of diameter dimension for NC turning, and simplified the dimension chain of process system, "three instantaneous centers" method is presented for predicting the accuracy of parts. After measuring and identifying the errors from process system and forced deformation in practice, the visual predicting model is setup for virtual NC turning. An example is also given to show the effectiveness of the model. |
