Sensitivity Analysis of Tool Axis Errors in Large Mill-Turn Machine Tools

Abstract:

This paper proposes an approach to carry out sensitivity analysis of tool axis errors caused by component geometric errors, in order to meet the high precision requirement in holes series machining with mill-turn machine tools. Firstly, ideal kinematic model and real kinematic model considering geometric errors of the mill-turn machine tools are built respectively based on homogeneous transfer matrix and multi-body system theory. Secondly, tool axis errors caused by component geometric errors are simulated using an orthogonal test. Finally, sensitivity analysis of tool axis errors is implemented by means of range analysis and variance analysis.
