The texture and cutter and design method of the section shape of line.
Background technique
It is carried out in cutting process to various workpiece materials, optimizes tool geometry, reduction is cut material pair
The friction of cutter reduces cutting resistance, improves stock-removing efficiency, reduces production cost, is the problem of people extremely pay close attention to.
The drag reduction structures of modern mimetic bio-membrane are studied and practice discovery: some animals, such as insect, snake, pangolin, shark
Equal animals body surface is not completely smooth, and there is a kind of geometric non-smooth features, its main feature is that certain geometrical shape is micro-
Small structural unit randomly or is regularly distributed in the certain positions of body surface, and structural unit shape has ditch flute profile, dimple-shaped, convex hull-shaped
With scale shape etc..Friction surface is not that more smooth then frictional force is smaller, these microcosmic surface shapes with certain Non-smooth surface form
The surface of looks (Surface Texture) often has smaller frictional resistance and stronger resisting breakage ability, and different non-smooth surfaces
Form have different degrees of influence to antifriction performance.
At present most of shape of tool surface texture designed by people be triangle, when triangular groove width compared with
When big, the phenomenon that can generate " secondary cutting " on cutter rake face, cutting resistance can be made to increase instead, reduction cutting is not achieved
The purpose of resistance, therefore, design through the invention can solve triangular configuration groove when width is larger, before cutter
The phenomenon that " secondary cutting " is generated on knife face.
Summary of the invention
The technology of the present invention solves the problems, such as: overcoming the deficiencies of the prior art and provide a kind of easily importing Bionics texture and knife

And it applies in the design of cutter rake surface texture configuration.
It is extracted by the section shape to bionical object pangolin scales transverse direction rib, fitting obtains its section curve
Fit equation, by fit equation be applied to cutter rake surface texture configuration design；And knife before decision cutter is determined
The major parameter of face Surface Texture configuration.
The present invention adopts the following technical scheme that in order to solve the technical problem
A kind of easily to import Bionics texture, the section shape of the texture is the section shape of pangolin scales transverse direction rib
Shape；The section shape is made of two sections of line segments, when x is (0, a) section, hatching is parabola；When x is in the section (0 ,-b),
Hatching is oblique line, and the equation of the hatching is as follows:
Hatching described in above-mentioned equation is as shown in figure 3, in figure:
X-is the lateral coordinates of Bionics texture hatching；
Y-is the longitudinal coordinate of Bionics texture hatching；
A-is the lateral length of parabola branch in Bionics texture hatching；
B-is the lateral length of Bionics texture hatching bend part；
H-is the height of Bionics texture hatching.
The easy importing Bionics texture is applied on cutter, is constituted and is easily imported Bionics texture cutter.
The easy design method for importing Bionics texture and carrying out cutter, comprising the following steps:
Step 1: determining the anterior angle and relief angle of cutter, cutter is drawn in the orthogonal cross-section perpendicular to main cutting edge
Two-dimensional cross section, section of the cutter in orthogonal plane are made of rake face (face that chip is flowed out), flank and tool nose；
Step 2: start texture starting point described in claim 1 at point of a knife distance C on the rake face 1 of cutter, it is described
The section shape of texture uses formula (1), and the width of texture groove is W, the a+b being equal in formula (1) in figure；Texture groove
Depth is h；The shape of texture groove is made of one end parabola and a diagonal line.
Step 3: starting to construct with the first texture in the position of distance the first texture groove end point L along cutter rake face
Second texture groove of groove-of identical texture；Along cutter rake face, in the position of distance the second texture groove end point L
Start to construct groove-third texture groove with the identical texture of the first texture；So circulation, until required for meeting
The trench length of texture, to complete the design of cutter.
Designed cutter rake face texture section is as shown in figure 4, related parameter is as follows in figure:
C-texture starting point is with a distance from tool nose point；
W-texture groove width, equal to the a+b in formula；
Distance between the adjacent texture groove of L-；
H-texture groove depth.
Compared with the prior art, the invention has the advantages that:
(1) the easy shape for importing Bionics texture obtained is applied the texture design in cutter rake face by the present invention
On, the friction of cutter rake face can be made to reduce, cutting force decline, cutting power reduces.
(2) section shape of the present invention according to pangolin scales transverse direction rib, the Bionics that one kind of design easily imports
Texture, and apply on the rake face of cutter.By experimental result: designed Bionics texture cutter, which has, to be reduced
The effect of cutting force, show designed texture configuration be easily guided into chip friction process, reduce between knife-bits
Friction.
Detailed description of the invention
Fig. 1 is pangolin scales appearance；
Fig. 2 is the microscopic appearance of pangolin scales transverse direction rib；
Fig. 3 is the shape for easily importing Bionics texture；
Fig. 4 is designed cutter rake face texture section.
Specific embodiment
As shown in Figure 1, 2, a kind of profiling characteristic for easily importing Bionics texture of the present invention is the structure of the bionical texture
Shape is the section shape of pangolin scales transverse direction rib.
The shape of Bionics texture is easily imported as shown in figure 3, simultaneously characterizing as the following formula:
It is set as shown in figure 4, applying the easy shape for importing Bionics texture obtained in the texture of cutter rake face
On meter, carry out as follows:
Step 1: determining the anterior angle and relief angle of cutter, cutter is drawn in the orthogonal cross-section perpendicular to main cutting edge
Two-dimensional cross section, as indicated at 4, in figure 1 be cutter rake face, 2 be cutter flank；
Step 2: starting texture starting point, the shape of texture such as formula at point of a knife distance C on the rake face 1 of cutter
