3rd, planing tool is moved into Working position, typically using the overall diameter of face gear 1 nearby as beginning Working position.Work as planing tool
After moving to Working position, since the corner of virtual spur gear 2 is 0 degree, planing tool is according to the cutter path planned by virtual straight-tooth
The axial profile inside of the virtual tooth of wheel 2 all machines away, and then face gear 1 is as virtual spur gear 2 is with constant corner ratio
A small angle is rotated, planing tool does the cutting movement of a cycle along the profile of virtual tooth.After being so sequentially completed repeatedly
Stock removal action after continuous swing every time and swing, until cutting a complete unilateral flank of tooth.
4th, after the complete flank of tooth in side is processed, virtual spur gear 2 goes back to 0 degree, with opposite direction of rotation, face gear
1 is taken turns than rotating a small angle, planing tool 3 with constant corner with virtual spur gear 2 still according to the axial direction of virtual tooth
Exterior feature does the cutting movement of a cycle.Stock removal action after being so sequentially completed follow-up swing every time repeatedly and swinging, until cutting
Cut out another complete unilateral flank of tooth.
5th, after a complete teeth groove is machined, planing tool exits machined teeth groove, as platen is divided
Degree motion, the rotation of face gear 1 360/NfDegree, processes next teeth groove.So repeatedly, the institute until processing entire surface gear 1
There is teeth groove.
The specific embodiment of milling face gear is：
1st, opposite gear 1 is heat-treated in advance, to improve the combination property of material.Face gear 1 is installed on coordinate system

2nd, milling cutter is moved into tool setting position, is carried out to knife.
3rd, milling cutter is moved into Working position, typically using the overall diameter of face gear 1 nearby as beginning Working position.Work as milling cutter
After moving to Working position, milling cutter does rotation at a high speed around main shaft.Since the corner of virtual spur gear 2 is 0 degree, milling cutter is according to planning
Cutter path the axial profile inside of the virtual tooth of virtual spur gear 2 all be milled away, then face gear 1 is with virtual straight
Gear 2 does the cutting movement of a cycle along the profile of virtual tooth with constant corner than rotating a small angle, milling cutter.
Stock removal action after being so sequentially completed follow-up swing every time repeatedly and swinging, until cutting a complete unilateral flank of tooth.
4th, after the complete flank of tooth in side is processed, virtual spur gear 2 goes back to 0 degree, with opposite direction of rotation, face gear
1 with virtual spur gear 2 with constant corner than rotate a small angle, axial profile of the milling cutter still according to virtual tooth
Do the milling campaign of a cycle.Stock removal action after being so sequentially completed follow-up swing every time repeatedly and swinging, until cutting
Go out another complete unilateral flank of tooth.
5th, after a complete teeth groove is machined, milling cutter exits teeth groove, as platen carries out dividing movement, face
Gear 1 rotates 360/NfDegree, to process next teeth groove.So repeatedly, the institute's geared surface until processing entire surface gear 1.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example.To those of ordinary skill in the art, the improvement and change resulting in the case where the technology of the present invention concept thereof is not departed from
Change and also should be regarded as protection scope of the present invention.
