Many small-size precise plastic helical involutes gears are used in electrical appliances to transmit rotary movements continuously and smoothly.Ball-end milling is an effective method for trial manufacture or small batch production of this type of gear,but the precision of the gear is usually low.In this research,the main sources of the errors of the gear,machining errors of the tooth profile and trace of the gear obtained were analyzed.The correction amounts for these errors are then determined by using a CNC gear tester.They are used to generate a new 3D-CAD model for gear machining with better precision.
