| Abstract: | As a new generation of machine tools in manufacturing, parallel structured virtual axis machines have drawn much concern about their advantageous stiffness property and accuracy. This paper applies the results of previous work on a mechanism stiffness calculation method to 6-legged virtual axis machine tools for the analysis of their dynamic processing. Their stiffness mathematical models are established by using vectors, and their numerical simulations with different parameters are conducted. The conclusions can provide algorithm for the control and real-time calibration of machining accuracy and a very important theoretical basis for optimum configuration, workspace and loading design. |
