Technical field
The present invention relates to processing technology control field, specifically a kind of ultrasonic cutting method using straight sword sharp knife.
Background technology
Ultrasonic straight sword sharp knife is a kind of in food cutting, composite material (such as carbon fiber or aramid fiber) machining field
The special process cutter applied in industry, cutter hub usually in the form of sheets, and have sharp cutting edge.The cutter is in ultrasonic vibration system
Under the driving of system, make the axial high-frequency vibration generated in process in 20kHz to 40kHz ranges of cutter, while cutter edge
Specified path is fed, and the blade of straight sword sharp knife is allowed to cut material.Since cutter has certain thickness, cutter being cut into material
Meanwhile blade two sides carry out lateral compression to material.Material under the ultrasonic vibration effect and knife side squeezing action of blade,
Complete shear action.Although the vibration of supersonic frequency can make cutter more easily cut material, cutter is reduced in direction of feed
Cutting force, reduce material allows knife to act on, improve machining accuracy.But straight sword sharp knife itself has certain thickness, so
Ultrasonic straight sword sharp knife inevitably generates squeezing action to the material of joint-cutting both sides.Because the material processed is soft plasticity material
Material, this squeezing action can generate bonding of the conquassation deformation to material in finished surface, and surface mechanical properties etc. impact.Than
The honeycomb core material of the ultrasonic straight sword sharp knife cutting of such as application, the conquassation pattern on surface directly affect its performance.

Ultrasonic vibration cutting is carried out to material to chip side, and by machining locus；
S3, quality testing is carried out to the processed materials surface obtained after ultrasonic vibration cutting, if detection passes through, processed
It completes, if detection does not pass through, thens follow the steps S4；
S4, rotation amount of the straight sword sharp knife around its cutter shaft initial rotation is further increased, and by machining locus to material
Ultrasonic vibration cutting is carried out, executes step S3 later.

Amount is equal to λ0When, the flank of the straight sword sharp knife is bonded machined surface, and the straight sword sharp knife is around its cutter shaft initial rotation amount
More than λ0When, the flank of the straight sword sharp knife is far from machined surface.
In the step S1, the straight sword sharp knife parameter is measured by photoelectric sensor.
The flank to the straight sword sharp knife during material progress ultrasonic vibration cutting and machined table by machining locus
Angle between face is constant, that is, if machining locus is straight line, the straight sword sharp knife is remained during ultrasonic vibration cutting
It is constant around its cutter shaft initial rotation amount；If machining locus is curve, the straight sword sharp knife is adjusted around its knife according to machining locus
Axis rotates, and keeps the angle during ultrasonic vibration cutting between the flank and machined surface of the straight sword sharp knife constant.
Compared with prior art, the present invention can effectively reduce extruding of the flank to machined surface of straight sword sharp knife,
Improve the suface processing quality of material.
The present invention can be widely popularized in fields such as processing technology controls based on the above reasons.
