Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, a shaping milling cutter for processing of a side double-concave arc part comprises a cutter handle 1 and a cutting tool bit 2 arranged at the end part of the cutter handle 1, wherein the cutting tool bit 2 comprises six cutting seats 3, a chip groove 4 is formed between every two adjacent cutting seats 3, each cutting seat 3 is provided with a side cutting edge 5, the rear side of each side cutting edge 5 is provided with a rear cutter face I6 and a rear cutter face II 7, each side cutting edge 5 is composed of a plurality of sections of straight edges and an arc edge, and each two adjacent sections of edges are tangent.
The end face of the cutting bit 2 is a flattened end face 8. The end of the cutting insert 2 does not participate in the machining of the part and is therefore a flattened end face 8.
The chip groove 4 is a chute, and compared with a spiral groove, the chute can better ensure the size precision of the middle convex profile of the part.
The rake angle of the side cutting edge 5 is 10 °.
The selection of the rake angle of the side cutting edge 5 can improve the cutting sharpness of the tool and ensure the smoothness of the product cutting.
The front angle is 10 degrees, so that the contact area between the front angle and a cut product can be reduced, and chip removal is facilitated.
Referring to fig. 4, in order to improve the machining precision of a product, the side cutting edge 5 sequentially includes a straight edge i 51, an arc edge i 52, a straight edge ii 53, an arc edge ii 54, a straight edge iii 55, an arc edge iii 56, a straight edge iv 57, an arc edge iv 58, a straight edge v 59, an arc edge v 510, and a straight edge vi 511.
Wherein, straight sword I51 and straight sword VI 511 play the chamfer effect.
The included angles between the straight edges I51 and VI 511 and the axis of the milling cutter are respectively 30 degrees.
The radius of the circular arc edge I52, the radius of the circular arc edge III 56 and the radius of the circular arc edge V510 are 0.12mm, and the radius of the circular arc edge II 54 and the radius of the circular arc edge IV 58 are 0.2 mm.
Since the cutting side edge 5 has the flank face i 6 and the flank face ii 7, each cutting seat 3 of the present embodiment has the clearance angle i and the clearance angle ii, respectively.
The clearance angle I of cutting seat 3 is 14 degrees, and the clearance angle II of cutting seat 3 is 28 degrees, and the width between clearance angle I and the clearance angle II is 0.1 mm.
The selection of the angle of the clearance angle I and the clearance angle II can be beneficial to chip removal of the cutter.
The diameter of the knife handle 1 is 10 mm.
The selection of the parameters such as the included angles between the straight edges I51 and VI 511 and the axis of the milling cutter, the radius of each arc edge, the width between the clearance angle I and the clearance angle II, the diameter of the cutter handle 1 and the like is not limited to the numerical values provided by the embodiment, and the selection can be carried out according to the specific specification of the product to be processed.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
