Technique rigidity and damping shock absorption, reach the purpose for suppressing chatter, as shown in Figure 1.
Traditional cutting parameter optimizes, tool path optimization method can only all solve specific Flutter Problem, passes through addition
Although the method that filler suppresses blade flutter can improve blade flutter problem, a series of other problemses are also brought：(1) by
Workpiece is pulled down to add filler before finishing in needs, and the technological preparation time greatly increases；(2) in process, filling
Thing is interfered with handle of a knife, it is necessary to which extra processing or filler are cleared up；(3) in filler and filler solidification process is added,
Deformable blade can be caused, influence machining accuracy；(4) filler of portion of material can damage lathe filtration system and pollution is cut
Bits；(5) it is expensive using material fillers such as sn-bi alloy, increase manufacturing cost.
The content of the invention
In view of this, the present invention provides a kind of passivation side of aluminium alloy thin-walled blade flutter suppressing method and its cutting tool

Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present embodiment provide it is a kind of cut aluminum alloy thin wall vane when Flutter Suppression method, this method changes traditional solution
The certainly thinking of blade flutter problem, from cutting tool, specific passivating method is used to its cutting tool, using passing through this
The aluminium alloy thin-walled blade of Tool in Cutting after method passivation, can reach under conditions of without using supplementary means such as fillers
Suppress the purpose of chatter, no flutter cutting is realized, so as to which the cutting quality of blade be effectively ensured.
The thinking of described Flutter Suppression method is：The blunt of smooth R10 μ ms is formed by finishing tool cutting edge
Change fillet, possess higher wearability, play a part of suppressing regenerative chatter and frictional property flutter, reach no flutter cutting
Purpose.
To realize the purpose of Flutter Suppression, it focuses on the passivation to cutting tool, and its passivation step is ground including cutter
Material passivation and Tool in Cutting passivation.Type selecting is carried out to cutter first, from the uncoated rose cutter of 3-4 swords, to ensure cutting edge circle
The wearability at angle, cutter material use hard alloy.The unusable conventional dry abrasive material of abrasive material during cutter abrasive material passivation simultaneously,
Abrasive material need to be prepared with the following method：Mixed, mixed with silicon carbide abrasive particles using high molecular polymer (such as silastic polymer)
Grit size adds lubricant and carries out viscosity adjustment, every kilogram of abrasive material adds 500mL-1000mL between 10 μm to 50 μm afterwards
Lubricant, form semisolid abrasive material.Adjust lubricant addition so that semisolid abrasive material has viscoplasticity, flexibility, flowing
Property, the characteristic such as adhesion metal, guarantee can rounding and can play surface finish.
When cutter abrasive material is passivated, the cutting edge position of selected uncoated rose cutter is put into and prepared using the above method
Abrasive material in, the rotation of driving cutter is simultaneously moved in abrasive material along horizontally and vertically direction, and passivation parameter is：Cutter linear velocity
Vc=7m/min-25m/min, feed speed F=100mm/min-500mm/min, passivation time t=10min-30min.
After carrying out abrasive material passivation to cutter, then cutting passivation is carried out, i.e., cutting edge roundness is made certainly by the blank that cuts aluminum alloy
So blunt, aluminium alloy blank is hemispherical or blade-shaped, ensures that cutting edge roundness real work region (finishes in working angles
Contact area (2) uniform wear during blade.Passivation time t=1h-30h is cut, cutting passivation time is joined according to cutter and cutting
Number adjustment.
By above-mentioned steps to cutting tool dulling after, in the range of cutter life carry out blade finishing i.e. can be achieved without flutter
Cutting.Described cutter life scope refers to carries out blade processing until when the line that quivers occurs again during the use of cutter using the cutter
Between, the aluminum alloy materials such as processing LD7, cutter life is generally up to 2000h-2600h.
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
