Technical field
The present invention relates to a kind of texture configuration and cutter and design method, pangolin scale transverse edge is more specifically imitated
The texture and cutter and design method of the section shape of line.
Background technology
In various workpiece materials are carried out with cutting process, optimize 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 research and practice of modern mimetic bio-membrane are found：Some animals, such as insect, snake, pangolin, shark
Not it is completely smooth Deng animal body surface, there is a kind of geometric non-smooth feature, be characterized in the micro- of certain geometrical shape
Small construction unit randomly or is regularly distributed in some positions of body surface, and construction unit shape has ditch flute profile, dimple-shaped, convex hull-shaped
With scale shape etc..The not more smooth then frictional force of friction surface is smaller, and these have the microcosmic surface shape of 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.
Most of shape of tool surface texture designed by current people is triangle, when triangular groove width compared with
When big, the phenomenon of " secondary cutting " can be produced on cutter rake face, can increase cutting resistance on the contrary, not reach reduction cutting
The purpose of resistance, therefore, by the design of the present invention, can solve triangular configuration groove when width is larger, before cutter
The phenomenon of " secondary cutting " is produced on knife face.

Described 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 progress cutter, comprises 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 is made up of rake face (face that chip is flowed out), rear knife face and tool nose；
Step 2: from texture starting point described in claim 1 is started at point of a knife distance C on the rake face 1 of cutter, it is described
The section shape of texture uses the width of texture groove in formula (1), figure to be W, equal to the a+b in formula (1)；Texture groove
Depth is h；The shape of texture groove is made up of one end parabola and one section of oblique line.
Step 3: along cutter rake face, starting to build with the first texture in distance the first texture groove end point L position
Groove-the second texture the groove of identical texture；Along cutter rake face, in distance the second texture groove end point L position
Start to build the groove-three texture groove with the first texture identical texture；So circulation, until required for meeting
The trench length of texture, so as to complete the design of cutter.
Designed cutter rake face texture section in figure as shown in figure 4, have related parameter as follows：
C-texture starting point from tool nose point with a distance from；
The width of W-texture groove, equal to the a+b in formula；
Distance between L-adjacent texture groove；
The depth of h-texture groove.
Compared with the prior art, the present invention has the beneficial effect that：
(1) present invention applies the shape of the easy importing Bionics texture obtained the texture design in cutter rake face
On, it can reduce the friction of cutter rake face, cutting force declines, cutting power reduction.
(2) present invention is according to the section shape of the horizontal rib of pangolin scale, a kind of Bionics easily imported of design
Texture, and apply on the rake face of cutter.Pass through experimental result：Designed Bionics texture cutter, which has, to be reduced
The effect of cutting force, shows that designed texture configuration, with being easily guided into chip friction process, is reduced between knife-bits
Friction.
