摘要

动态车削是一项最新的技术，允许使用不同切削刃的刀片，并通过控制主轴旋转和切削参数的同步变化来修改侧切削刃角度。这使得通过减少更换工具来消除停机时间成为可能。在航空部件的车削中，切屑断裂是一个相关的事实，因为当使用耐热的高温合金时，它允许更高的散热性能，这些材料会迅速降解插入物。为了使试验动态车削刀片的设计适应航空部件的加工，采用不同的固定侧切削刃角度对试验动态车削刀片的切削性能进行了初步研究，得出虽然切削性能良好，但在精加工条件下不能正常工作，因此必须通过减小其与切削刃的距离对其进行重新设计。关键词:动态车削;高饲料;航空航天高温合金;碎料机，侧切边角。

INFLUENCE OF SIDE CUTTING EDGE ANGLE ON THE DESIGN OF THE CHIPBREAKER: STUDY OF DYNAMIC AND HIGH FEED TURNING TOOLS IN INCONEL® 718

Dynamic turning is a recent technology that allows inserts with different cutting edges to be used and the side cutting edge angle to be modified by controlled spindle rotation and synchronised variation of the cutting parameters. This makes it possible to eliminate downtime by reducing tool changes. Chip breaking is a relevant fact in the turning of aeronautical parts, as it allows a higher heat dissipation performance when working with heat-resistant superalloys, materials that degrade inserts rapidly. An initial study has been carried out, using different fixed side cutting edge angles, to test the chipbreaker performance of an experimental dynamic turning insert in order to adapt its design to the machining of aeronautical components, obtaining that, although the cutting performance is good, the chipbreaker does not perform correctly in finishing conditions, and therefore it must be redesigned by reducing its distance to the cutting edge. Keywords: dynamic turning; high feed; aerospace superalloy; chipbreaker, side cutting edge angle.
