Machining with rotating tools appears to be an efficient method that employs a non-standard kinematic turning scheme. It is used in the machining of materials that we classify in the category of difficult to machine. The titanium alloy Ti-6Al-4V, which is widely used in industry and transportation, is an example of such material. Rotary tool machining of titanium alloys has not been the subject of many studies. Additionally, if researchers were dissatisfied with their findings, the reason may not be the kinematic machining scheme itself but rather the tool design and the choice of cutting parameters. When tools are constructed of several components, inaccuracies in production and assembly can arise, resulting in deviations in the cutting part area. A monolithic driven rotary tool eliminates these factors. In the machining process, however, it may react differently from multi-component tools. The presented work focuses on the research of the technology for machining titanium alloy Ti-6Al-4V using a monolithic driven rotary tool. The primary goal is to gather data on the impact of cutting parameters on the machining process. The cutting force and the consequent integrity of the workpiece surface are used to monitor the process. The speed of workpiece rotation has the greatest impact on the process; as it increases, the cutting force increases, as do the values of the surface roughness. In the experiment, lower surface roughness values were attained by increasing the feed parameter and the depth of cut. This may predetermine the inclusion of a kinematic scheme in highly productive technologies.
使用旋转刀具进行加工似乎是一种采用非标准运动学车削方案的高效方法。它用于加工我们归类为难加工材料的材料。广泛应用于工业和交通运输领域的钛合金Ti-6Al-4V就是这类材料的一个例子。钛合金的旋转刀具加工尚未成为众多研究的主题。此外,如果研究人员对他们的发现不满意,原因可能不是运动学加工方案本身,而是刀具设计和切削参数的选择。当刀具由多个部件构成时,生产和装配中可能会出现不准确情况,从而导致切削部分区域出现偏差。整体驱动的旋转刀具消除了这些因素。然而,在加工过程中,它的反应可能与多部件刀具不同。本文所介绍的工作重点是研究使用整体驱动旋转刀具加工钛合金Ti-6Al-4V的工艺。主要目标是收集有关切削参数对加工过程影响的数据。切削力以及随之而来的工件表面完整性用于监测加工过程。工件的旋转速度对加工过程影响最大;随着旋转速度增加,切削力增加,表面粗糙度值也增加。在实验中,通过增加进给参数和切削深度获得了较低的表面粗糙度值。这可能预先决定了在高效加工技术中采用该运动学方案。
