Please in the lump referring to Fig. 2 to Fig. 4, first cutting edge 121 is obliquely extended to the outer circumference surface near cutter hub 11 middle parts from the end face of cutter hub 11 front ends 112, its bearing of trend roughly with the rotation a oblique of cutter hub 11, and crooked towards the cutting direction of profile milling cutter 100.When cutter hub 11 rotated a circle around its rotation a, first cutting edge, 121 formed cutting faces 1212 were a conical surface.
Observe from front end 11 rearward end 12 of cutter hub 11; On the direction of rotation of cutter hub 11; Promptly the rotation a with cutter hub 11 is on the circumference at center; First cutting edge 121 and second cutting edge 123 are crisscross arranged, thereby when moulding milling cutter 100 carried out cut, first cutting edge 121 and second cutting edge 123 successively cut workpiece.In the present embodiment, first cutting edge 121 and the projection in the cross section of second cutting edge, 123 cutter hubs 11 roughly are cross and intersect.
The 3rd cutting edge 125 is formed at the end face of cutter hub 11 front ends 112 and is connected with first cutting edge 121.The 3rd cutting edge 125 is from outer surface radially the extending to cutter hub inside along cutter hub 11 of cutter hub 11.In the present embodiment, two article of the 3rd cutting edge 125 is connected at the rotation a place of cutter hub 11.
The 4th cutting edge 127 is formed at the outer surface of cutter hub 11; The one of which end is connected with the end that second cutting edge 123 is positioned at cutter hub 11 outer surfaces; The other end extends along the direction near handle of a knife 13 in the rotation a of cutter hub 11 direction, and roughly crooked towards the cutting direction of profile milling cutter 100.The 4th cutting edge 127 is roughly vertical each other with second cutting edge 123 with the projection in the determined plane of cutter hub 11 rotation a at second cutting edge 123.
Should be noted that; The sword molded lines of first cutting edge 121, second cutting edge 123, the 3rd cutting edge 125 and the 4th cutting edge 127 does not receive the restriction of embodiment of the invention concrete form; The shape of its sword molded lines can be confirmed according to the external surface shape of the required moulding of workpiece; Can be linear etc. such as above-mentioned sword molded lines for zigzag, wave, on workpiece, to form zigzag or waveform surface.
Above-mentioned each cutting edge 121,123,125,127 and cutter hub 11 are one-body molded, thereby the structure of profile milling cutter 100 is comparatively compact, helps the miniaturization of profile milling cutter 100, to satisfy miniature parts, such as the cut requirement of portable type electronic product housing.
The profile milling cutter 100 of the embodiment of the invention can form four surfaces that connect successively through a Milling Process on workpiece, the junction on wherein adjacent two surfaces can be wedge angle, is connected through the very little arc section of radius between these two surfaces in other words.Be that example is explained forming method of the present invention the side of plate workpiece is carried out Milling Process below.
The sketch map that is meshed with workpiece 200 during profile milling cutter 100 cutting workpieces 200 for the embodiment of the invention shown in Figure 5.The method of utilizing 100 pairs of workpiece of profile milling cutter 200 of the embodiment of the invention to carry out Milling Process comprises following basic step:
(1) above-mentioned profile milling cutter 100 is provided, and profile milling cutter 100 is clamped on the control device, on the main shaft such as plain-milling machine or CNC milling machine.Preferable selection provides CNC milling machine and profile milling cutter 100 is clamped on the main shaft of CNC milling machine.
(2) workpiece 200 is clamped in the workbench of milling machine, and mobile profile milling cutter 100 carries out tool setting, to confirm the position of profile milling cutter 100 in workpiece coordinate system.
(3) main axis rotation of milling machine and drive profile milling cutter 100 and rotate around its rotation a, the main shaft of milling machine cuts along the machining path feed of presetting with profile milling cutter 100.First cutting edge 121 and be attached thereto the 3rd cutting edge 125 that connects and on workpiece 200, process first surface 211 and the 3rd surface 215, the second cutting edges 123 and the 4th cutting edge 127 that is attached thereto and reprocess out second surface 213 and the 4th surface 217.Wherein, first surface 211 and second surface 213 intersects, and the part that first surface 211 and second surface 213 define jointly is outside outstanding to workpiece 200.When the milling moulding, the first surface 211 that forms on the workpiece 200 and the material of second surface 213 intersections are earlier after the cutting of first cutting edge 121 and second cutting edge 123, thereby first surface 211 and second surface 213 connections can form wedge angle β.The angle of wedge angle β is by the decision of the relative position between first cutting edge 211 and second cutting edge 213, promptly by projection and angle second cutting edge 123 between the decision of first cutting edge 121 in second cutting edge 123 and the determined plane of rotation a.Can be according to actual needs, the relative position relation and the shape of appropriate design first cutting edge 211 and second cutting edge 213 are to form the wedge angle β of different angles.
In step (3), the machining path of profile milling cutter 100 can be set through CNC milling machine is carried out pre-programmed, and it is stored in controller or the personal control.Certainly, the mode that profile milling cutter 100 control Scheme Selection is also comprised manual control.
With reference to above-mentioned forming method, adopt the profile milling cutter 100 of the single embodiment of the invention time processing to go out four four surfaces 211,213,215,217 that connect successively, and wherein the connection on two surfaces 211,213 is wedge angle β.Utilize profile milling cutter of the present invention and forming method can avoid tool changing or clamping workpiece again, reduce therefore spent man-hour, working (machining) efficiency is provided, and can avoid the error accumulation that causes because of tool setting again, improved machining accuracy.
Be appreciated that; The quantity of the cutting edge of profile milling cutter of the present invention does not receive the restriction of embodiment; Such as; It can only comprise first cutting edge 121 and second cutting edge 123, utilizes this profile milling cutter can on workpiece 200, process first surface 211 and second surface 213, and first surface 211 can form wedge angle equally with second surface 213 connections.Certainly, profile milling cutter of the present invention can also comprise five even more cutting edge, on workpiece, to process satisfactory shape.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
