摘要

间歇转弯（IT）的特点与连续转弯（CT）不同。每次卸下负载并接合新表面时，切割工具都会受到冲击。这种中断会导致严重的切割条件，从而对性能参数产生致命影响。本研究的目的是评估四个切削因素，刀尖半径（r）、切削速度（Vc）、进给率（f）和切削深度（ap）对以下输出性能参数的影响：表面粗糙度（Ra）、切削温度（T°）和车削过程中切削刀具磨损（VB）（IT）AISI D3冷作工具钢。采用三层CVD（AI2O3/TiC/TiCN）涂层硬质合金刀具。采用田口L9（3^4）试验设计进行间歇车削试验。为了改进基于满足工业标准的三（3）个高度特定场景的性能参数，使用了期望函数（DF）和灰色关系分析方法（GRA）。最后，比较了两种策略的优化结果，以评估每种方法的性能。

Minimizing Tool Wear, Cutting Temperature and Surface Roughness in the Intermittent Turning of AISI D3 Steel Using the DF and GRA Method

Intermittent turning (IT) is characterized by a different context than continuous turning (CT). The cutting tool is shocked each time it goes off-load and engages a new surface. This interruption causes severe cutting conditions, which fatally affect the performance parameters. The purpose of this study is to assess the effects of four cutting factors, tool nose radius (r), cutting speed (Vc), feed rate (f), and depth of cut (ap), on the following output performance parameters: surface roughness (Ra), cutting temperature (T°), and cutting tool wear (VB) during turning (IT) AISI D3 cold work tool steel. A triple CVD (AI2O3/TiC/TiCN)-coated carbide cutting tool was used. A Taguchi L9 (3^4) experimental design was adopted for carrying out the experiments in intermittent turning. To improve the performance parameters based on three (3) highly particular scenarios that fulfill industrial criteria, the desirability function (DF) and the grey relational analysis method (GRA) were used. Finally, the optimization findings of the two strategies were compared in order to evaluate the performance of each method.
