Abstract:

A method of combining the response surface mode (RSM) and experimental design was presented based on the combination of different positions in the moving trajectory of the machine tool spindle box and the column in order to analyze the cutting stability in the whole processing spatial distribution. A combination at key position was selected as samples, and the dynamics property of the samples was calculated via ANSYS. The limit critical cutting depth of each sample was calculated, and the quadratic polynomial RSM reflecting the relation between position and stability of limit critical cutting depth was established. The limit critical cutting depth in the entire space approximation was calculated, and the quality of RSM was further evaluated. The great influence of position changes of moving parts on the stability of cutting was shown with a high speed horizontal machining center (MC) as an example, providing some theoretical support for optimization of machining process and structure design．
