摘要

因瓦尔36以其低热膨胀系数而闻名，广泛应用于复合模具、电子和光学等领域。虽然电弧增材制造（WAAM）为Invar 36提供了高沉积速率和成本效益，但它会产生粗糙的表面纹理，需要作为后处理进行加工。为了克服Invar 36的可加工性挑战，超声波振动辅助加工（UVAM）首次应用于waam制造的Invar 36。结果表明，UVAM在切削力、表面粗糙度和形貌、亚表面显微硬度和刀具磨损方面都优于常规加工，在构建和沉积方向上都有改善。

Ultrasonic vibration-assisted machining of invar 36 alloy manufactured by wire arc additive manufacturing

Invar 36, known for its low coefficient of thermal expansion, is widely used in applications like composite moulds, electronics, and optics. Although Wire Arc Additive Manufacturing (WAAM) offers high deposition rates and cost-effectiveness for Invar 36, it creates rough surface textures requiring machining as post-processing. In order to overcome Invar 36′s machinability challenges, Ultrasonic Vibration-Assisted Machining (UVAM) was applied for the first time on WAAM-fabricated Invar 36. The results showed that UVAM outperformed conventional machining in terms of cutting force, surface roughness and topography, subsurface microhardness and tool wear with improvements observed in both building and deposition directions.
