An innovative cutter spindle feed mode used for heavy-duty spiral bevel gear CNC machine tool

Abstract

In this study, in order to increase manufacture efficiency and improve machining precision of heavy-duty spiral bevel gear CNC (Computerized Numerical Control) machine tool, an innovative cutter spindle feed mode replacing the traditional work piece or spindle box feed mode used for heavy-duty spiral bevel gear CNC machine tool is proposed. The method is described as follows. Firstly, a three-dimensional structural model of heavy-duty spiral bevel gear CNC machine tool adopting the proposed cutter spindle feed mode is designed. Then, the numerical control machining model of heavy-duty spiral bevel gear CNC machine tool using the cutter spindle feed mode is constructed, including determining cutter location parameters, establishing machining coordinate system and calculating motion parameters. An example is consequently demonstrated to verify the established numerical control machining model. Finally, a virtual simulation model and an experimental model of heavy-duty spiral bevel gear CNC machine tool adopting the proposed cutter spindle feed mode are established and the validation of the proposed cutter spindle mode is conducted. Both the virtual simulation and experimental results show that the proposed cutter spindle feed mode used for heavy-duty spiral bevel gear CNC machine tool is feasible and effective with improved machining efficiency and accuracy.
