AI Technical Summary
Technical Problem
Existing milling tools are prone to delamination and fiber protrusion when machining fiber composites, and precise axial positioning is required to avoid these problems.
Method used
A milling tool is designed, comprising a clamping section and a cutting edge section, wherein left-hand and right-hand helical chip grooves are formed on the cutting edge section, and the cutting element has a squeezing and stretching circumferential cutting edge to ensure neutral cutting performance in all axial positions and avoid delamination and fiber protrusion.
Benefits of technology
It enables uniform cutting on workpieces of different thicknesses and materials, prevents delamination and fiber protrusion, and improves the length and service life of the cutting edge.

Abstract
本发明涉及一种用于机加工纤维复合材料的切削工具(100)，包括夹紧区段(1)和沿纵向轴线(Z)延伸的切削区段(2)。切削区段(2)具有基本圆筒形形状，其中，在切削区段(2)上形成多个左旋螺旋形式的第一容屑槽(LS)和多个右旋螺旋形式的第二容屑槽(RS)，相交的第一容屑槽(LS)和第二容屑槽(RS)在切削区段(2)上形成多个分立的切削元件(3)。切削元件(3)具有沿左旋螺旋延伸的第一周向切削刃(LR)和沿右旋螺旋延伸的第二周向切削刃(RR)，切削刃沿限定切削区段(2)的外周的共同的包络圆筒侧表面(ZM)延伸，并且第一周向切削刃(LR)和第二周向切削刃(RR)通向共同的尖端(7)，其中，各自以主自由角(1，1)延伸的相应的主自由表面(5，6)至少在多个切削元件(3)的一部分数量上沿周向方向邻接所述周向切削刃(LR，RR)，主所述自由表面(5，6)沿第一自由表面边缘(8)彼此邻接。
