| Abstract: | Working principle of a virtual axis machine tool was analyzed. Curve equation of ballend cutter blade was established. Using moving frame methods, a mathematical model of rake face and flank face was inferred. According to the mathematical model of ballend cutter tool and inverse solution model of the virtual axis machine tool, generalized cutter location contrail of the rotating cutter tool was deduced, and converted into the length of the pole under pole coordinates. Cutting action can be conducted through controlling the length of pole, and dissertate the advantages of virtual axis machine tool in cutting tool's machining. |
