Research on processing of large-size spiral bevel gear CNC machine tools

摘要

In this paper,a new type of large-size spiral bevel gear machine is used as a model to study the structural characteristics of spiral bevel gears.Geometric and mathematical models of the machine tool are established.According to the processing principle of spiral bevel gear by forming method with disc cutter,the position and angle of cutter relative to the workpiece are researched.The tool motion is converted to the machine tool coordinate system by coordinate transformation,then the tool trajectory can be obtained to provide the basis for the processing of spiral bevel gears.
