- Abstract:
- A way of tool axial dispersion was presented,and then each discrete unit of the variable helix cutterwas approximately simulated to be variable pitch cutter. Thus variable delay differential equations were trans-ferred to multi-delay differential equation. And the stability prediction model of variable helix milling was builtbased on the original ZOA method. Through comparisons with prior works,the prediction results are in good a-greement about 100% whether normal or variable helix cutter. Two methods were used to simulate. The calcu-lation time of the original method is more than 92 s,but for the proposed method is below 20 s.The resultsshow the proposed method can save computational time comparing with the original method. And the resultscould provide reference for the selection of reasonable processing parameters and chatter prediction in actualprocessing.
