Abstract
A cutting insert (20) for use in a rotary milling tool (10) is provided. The cutting insert (20) includes an insert body including a bottom face (22), a top face (24) and a side face (26). A stepped cutting edge (20) is formed at the intersection of the top face (24) and the side face (26) for engaging a workpiece and removing a chip from it. The stepped cutting edge includes at least two offset edge portions (30a-c) which produce distinct, transversely-spaced chip segments during the cutting operation. The offset edge portions (30a-c) are connected by transition edge portions (30d-e) which are disposed at an obtuse angle with respect to the offset edge portions. The angle of the transition edge portions tends to spread the individual chip segments apart during the machining operation to effect a thinning of the chip between the individual chip segments. The entire cutting edge is helically curved so that the cutting edge lies on the surface of a circumscribing cylinder defined by the rotation of the cutting edge about the axis of the milling cutter.
Description
The present invention relates generally to the cutting tip of rotary milling tools, is a kind of interchangeable cutting tip helical form cutting edge, that have a plurality of mutual compensation cutting tips that has specifically, is used for cutting straight side.
Milling cutter generally is made up of the cylinder cutter hub that outer surface has a plurality of grooves, is used for installing interchangeable cutting tip.Each cutting tip has a cutting edge at least, acts on to carry out milling on the workpiece.When designing the cutting tip of milling cutter, need to reduce the cutting force that the blade cut sword bears.Cutting force reduces the wearing and tearing and the fracture that just can reduce blade, prolongs cutter life.Cutting force hangs down also can reduce the power that milling machine operation needs.The size of this cutting force depends on that to a great extent the geometry of cutting tip reaches the orientation with respect to workpiece.
For most of rotary milling tools, blade has straight cutting edge.In order to reduce the cutting force that this straight sword bears, to make it when generally blade being installed with respect to the rotating shaft certain angle that tilts.This axioversion is called axial rake, and corresponding to the angle A among Fig. 7, herein, CL represents rotating shaft.This axial rake has improved the stock-removing efficiency of blade, but has also caused length direction along cutting edge, and cutting edge is with respect to the variable in distance of milling head rotating shaft, and cutting edge and the contact point of workpiece always are not positioned on the radius distance that equates apart from rotating shaft like this.This variation causes cutter to produce the convex bending of not expecting in the side of otch.Axial rake is big more, and the bending of otch side is just big more.In addition, because the influence at a cutting edge and an angle of axioversion that is cut the surface, for the blade that certain axial rake is arranged, chip-load reaches to cutting required energy, and is proportional with the length of cutting edge.The end face of blade is also very important for stock-removing efficiency.A characteristic quantity of end face is the angle of the rake face of blade with respect to workpiece.This angle is called radial rake, represents with c1, c2, c3 respectively in Fig. 9 to Figure 11.When radial rake be on the occasion of the time, the sword of blade with the planing the mode cutting workpiece.When radial rake was negative value, the sword of blade was with the mode cutting workpiece of scraping, and the efficient than planing effect is low usually.When the length of cutting edge increased, the major part of cutting edge was negative radial rake with respect to workpiece, made chip-load increase.When needs reduce the danger of cracking of cutter as far as possible, reduce the wearing and tearing of blade, reduce the required energy of cutting operation, load increases with the purpose that reduces chip-load to be disagreed.
As everyone knows, in order to reduce chip-load, can adopt the short relatively cutting tip of a plurality of cutting edges to replace the single edge sword of single long cutting edge.Insert design is overlapped for short cutting edge.Such design can reduce cutting force effectively, and in order to carry out smooth cutting, cutting tip must be proofreaied and correct each other exactly.
Obviously, even if under sizable axial rake, cutting tip also requires and can cut with smooth, straight side edge, does not adopt the dark groove that weakens structure on the cutter hub and be not desirably in.In the ideal, the cutting edge of this blade acts on the workpiece with positive radial rake on its total length substantially, makes cutting force and blade abrasion reduce.At last, such blade requires to cut off the metal fillings that produces owing to shear action effectively, improves the gross efficiency of the cutter that blade is housed.
The present invention is the cutting tip that is used for rotary cutting tool such as rotary milling tools and drilling tool.Blade is made up of the polygon cutter blade, comprises a plurality of sides between baseplane, end face, end face and the bottom surface.Cutting edge is intersected by end face and at least one side and forms, and acts on the workpiece, removes smear metal from workpiece.Cutting edge comprises at least two compensation blades, is linked to each other by the transition blade.Transition blade and compensation blade are in obtuse angle.
The cutting edge of each blade and transition blade all are positioned at cutting edge and rotate on the cylindrical envelope face that forms around cutter spindle, make each cutting edge become helical buckling.The each several part spiral of cutting edge guarantees to form smooth relatively straight side on workpiece.
In process, the compensation blade of cutting edge produces narrow, laterally spaced bits sheet, and the transition blade will be considered the sheet expansion to be worth doing, plays the effect of reconditioning bits sheet between the bits sheet.Such reconditioning produces local sclerosis between the bits sheet, make the smear metal embrittlement to be easy to chip breaking.
Another aspect of the present invention is that the cutting edge of each compensated part is with respect to the basal planes tilted of blade.Owing to, just can need not on the cutting plate for milling cutters pedestal, to open dark groove with the basal planes tilted of each cutting edge with respect to blade, just can obtain big axial rake, otherwise on the cutting plate for milling cutters pedestal, open dark groove, will too weaken the structure of cutter hub.
In sum, though the purpose of this invention is to provide a kind of when blade tilts with big axial rake on milling cutter body, cutter that also can the cutting workpiece straight sidewall.
Another object of the present invention provides a kind of cutting tip that is used on the rotary milling tools, improves the chip breaking ability.
