硬质木材榫槽组合铣刀设计的研究与实现

Research and Implementation of Combination Cutter Design for Tenoning Grooves on Hardwood

为解决小型台式多用木工机床加工硬质木材榫槽难的问题,设计了一款组合铣刀。以数块窄刀刃圆锯片组合代替宽刀刃,多刀刃代替双刀刃,组合时锯齿刀刃错位排列,各段直刃呈螺旋状,采用大前角改善切削性能,齿廓优化成刨削锯齿状以提高锯齿的耐用度和使用寿命。该铣刀具有分块式切削刀刃,切削性能优良,加工硬、软质木材榫槽时的进料速度比直齿双刃盘式成型铣刀提高3倍。

In order to solve the difficult problem with tenoning grooves on hardwood using small desktop multi-purpose wood working machine tools, a combination cutter is designed, wide blades replaced with narrow blade tool combination of circular saw blades, dual-blades replaced with muhi-blades. The serrated cutting edge is arranged in a spiral structure as certain angle in each straight edge segment. Large cutting edge inclination angle is used to improve cutting performance. The tooth profile is optimized into zigzag to improve durability and service life of the sawtooth. The cutter has a block cutting blade, ensuring excellent cutting performance, and the feed speed can be increased by three times compared to the other grooving cutting tools.
