Abstract: In order to create three dimensional solid models， verify designing parameters and machine setting parameters for cyclo-palloid bevel gears, the machining principle of cyclo-palloid bevel gears with Klingelnberg tooth system was analyzed. Based on AutoCAD 2008 development platform,  using ActiveX Automation technology and VBA programming language embedded in AutoCAD, the dimension-driven solid model of the workpiece and generating gear was established. Based on the machining principle of cyclo-palloid bevel gears， the relative position and movement between the workpiece and generating gear, the cutting process was simulated by subtraction boolean operation between workpiece and generating gear. The correctness of simulation system is validated by comparing simulation result with practical machining workpiece. The machining simulation system is meaningful for generating precise three dimensional solid models and verifying machine settings.
