摘要/Abstract

摘要： 对电弧微铸锻增材制造AlMgSc合金进行纵扭超声复合干铣削加工特性试验研究，探讨超声铣削工艺参数对切削力、表面形貌、加工硬化及刀具磨损等AlMgSc合金干铣削成形特性的影响规律。结果表明: 与锻造和常规电弧增材成形铝合金相比，微铸锻增材制造AlMgSc合金由于具备更加致密的微观组织、更高的强度和硬度而在超声干铣削成形过程中会产生更大的铣削力，更容易发生加工硬化。与常规干铣削相比，采用纵扭复合超声干铣削可以获得更小的表面粗糙度，并有利于减轻刀具磨损。

Abstract: The longitudinal-torsion compound ultrasonic vibration dry milling characteristics were experimentally studied for AlMgSc alloys formed by arc micro-casting and forging additive manufacturing. The influence rules of ultrasonic milling parameters, such as cutting force, surface morphology, work hardening and tool wear, were discussed about the dry milling forming characteristics of AlMgSc alloys. Results show that the arc micro-casting and forging additive manufactured AlMgSc alloys which have more dense microstructure, higher strength and hardness comparing with conventional forging and common arc added material forming aluminum alloys, may produce larger milling forces in ultrasonic dry milling processes and be more likely to occur work hardening phenomenon. And the longitudinal-torsion compound ultrasonic vibration dry milling may get lower surface roughness and is helpful to reduce the tool wear comparing with conventional dry milling.

Key words: longitudinal torsional ultrasonic vibration, dry milling, arc micro-casting and forging additive manufacturing, AlMgSc alloy, milling characteristics
