A　generating　method　with　tilted　double-sided　cutter　is　proposed　on　the　modification　control　question　of　whole　tooth　surface　of　cylindrical　gears　with　arcuate　tooth　trace.　According　to　the　new　generation,　through　adjusting　the　swing　radius　of　the　straight-edge　cutter　in　generating　movement,　the　modification　control　in　the　tooth　profile　direction　is　achieved;　through　adjusting　the　cutter-tilt,　the　modification　control　in　tooth　trace　direction　is　realized.　Based　on　the　spatial　kinematic　principle,　the　kinematic　transformation　from　traditional　machine　tools　with　tilted　angle　to　general　multi-axis　computer　numerical　control　(CNC)　ones　are　realized　by　vector　revolution.　In　the　transforming　process,　relative　position　and　relative　motion　of　the　workpiece　and　cutter　in　both　machines　are　invariable,　the　controlling　equations　of　generating　movement　of　the　gear　is　established.　Thereby　the　cylindrical　gears　with　symmetric　arcuate　tooth　trace　can　be　machined　by　the　general　multi-axis　CNC　milling　machine.　Then　through　the　cutting　experiments　of　the　work　piece　and　tooth　contact　checkout,　correctness　of　the　machining　methods　and　the　motion　equations　are　proved.　Through　comparing　this　method　with　traditional　machining　method,　it　has　high　efficiency,　simple　motion　relation　and　easily　to　extend　application.　©　2012　Journal　of　Mechanical　Engineering.
