AI Technical Summary
Technical Problem
Existing composite material cutting tools have difficulties in chip removal and heat dissipation, and their sharpness is insufficient, which leads to easy chip adhesion or clogging and poor machining quality.
Method used
A textured micro-tooth end mill is designed, which uses alternating mother and daughter helical grooves to form the main and secondary cutting edges. Combined with different rake angles and helix angles, a textured micro-tooth cutting edge is formed, which enhances sharpness and chip removal capability.
Benefits of technology
It improves the cutting efficiency of composite materials, reduces chip elongation and clogging, and enhances the surface quality and tool life.

Abstract
本发明公开了一种网纹微齿铣刀，包括沿中心轴线依次连接的切削部和刀柄部，切削部的周侧设有至少两条母螺旋槽和多条与母螺旋槽旋向相反的逆螺旋槽，相邻母螺旋槽之间形成刃瓣，刃瓣上设有至少一条与母螺旋槽旋向相同的子螺旋槽，母螺旋槽和子螺旋槽均贯穿至切削部远离刀柄部的一端，母螺旋槽与后侧的子螺旋槽在切削部的周侧相交形成主切削刃，相邻子螺旋槽在切削部的周侧相交形成副切削刃，逆螺旋槽将主切削刃和副切削刃分隔形成多排沿母螺旋槽螺旋方向间隔排列的网纹状微齿刃。本网纹微齿铣刀具有提高锋利性和加工质量，利于排屑及防止堵屑等优点。
