Turn-milling process has been paid attention in order to be used in multi-task machining processes. Moreover, looking for new machining techniques aimed at reducing cutting force is of important. Reducing cutting force in machining processes has the benefits of extending tool life and improving surface quality. One of the new concepts for reducing the cutting force is applying ultrasonic vibration. In this paper, effects of ultrasonic vibration under different machining parameters in turn-milling process of Al-7075 alloy will be investigated. In this order, a special mechanism was designed to apply ultrasonic vibration during machining process. Ultrasonic vibration exertion on the tool reduced cutting force and surface roughness up to 75% and 35%, respectively. Also tool rotational speed increment induced cutting force and surface roughness increment. In addition, tool feed rate and workpiece rotational speed increment caused cutting force and surface roughness increment. Although, feed rate was more influential.

为了将其用于多任务加工过程中，车削铣削过程已引起关注。此外，寻找旨在减小切削力的新加工技术也很重要。降低加工过程中的切削力具有延长刀具寿命和改善表面质量的好处。减小切削力的新概念之一是施加超声振动。本文研究了Al-7075合金车削过程中不同加工参数下超声振动的影响。按照这种顺序，设计了一种特殊的机制来在加工过程中施加超声振动。超声波振动作用在刀具上，切削力和表面粗糙度分别降低了75％和35％。刀具转速的增加也会引起切削力和表面粗糙度的增加。另外，刀具进给速度和工件转速的增加引起切削力和表面粗糙度的增加。虽然，进给速度的影响更大。
