The cutting-edge temperature on the flank face in dry turn-milling of medium carbon steel (ISO C45) is measured using a two-color pyrometer with an optical fiber. In turn-milling, undeformed chip geometry is complex due to its dependence on several factors including diameter of the cutting tool, number of tooth, diameter of the workpiece, tool-work revolution speed ratio, depth of cut, feed per tooth, tool axis offset, and the cutting distance. In this study, the undeformed chip is analyzed and visualized by the 3D-CAD system, and the effects of the cutting parameters in turn-milling, especially relative cutting speed and tool axis offset on tool flank temperature, are investigated. It is interesting that the relative cutting speed does not significantly affect the tool flank temperature, where it increases by approximately 20 °C at most when relative cutting speed increases from 124 m/min to 217 m/min. In addition, tool flank temperature varies by approximately 40 °C when the tool axis offset is changed from 0 mm to 9.2 mm due to the change in the undeformed chip geometry.

高效,高精度正交车铣的研究-相对切削速度和刀具轴偏置对刀具侧面温度的影响

使用带有光纤的双色高温计测量中碳钢(ISO C45)的干车铣中侧面的前沿温度。在车铣中,未变形的切屑几何形状很复杂,因为它取决于几个因素,包括切削刀具的直径,齿的数量,工件的直径,刀具-工件的转速比,切削深度,每齿的进给量,刀具轴偏移量和切割距离。在这项研究中,未变形的切屑通过3D-CAD系统进行分析和可视化,并研究了车削铣削中切削参数的影响,尤其是相对切削速度和刀具轴偏移对刀具侧面温度的影响。有趣的是,相对切削速度不会显着影响刀具侧面温度,当相对切削速度从124 m / min增加到217 m / min时,最多增加约20°C。此外,由于未变形的切屑几何形状的变化,当刀具轴偏移量从0 mm更改为9.2 mm时,刀具侧面温度变化约40°C。
