Banana fibre-reinforced polymer (BaFRP) composite can ensure environmentally friendly decomposition of waste material and reduction of cost in comparison with traditionally used fibre material. This article emphasizes the influence of various machining constraints on surface roughness (Ra) and cutting force (Pz) in turning alkaline-treated banana fibre-reinforced polymer (T-BaFRP) composite. 30% weight fraction yields satisfactory mechanical properties. Taguchi orthogonal array L25 is used to design experiments and optimization using DFA and TOPSIS. An experimental investigation was conducted under compressed cooling air-cutting conditions where pressure was kept at 8 bar. Analysis of variance depicts that depth of cut and feed rate are the most prominent factors for surface roughness and cutting force. The predicted and experimental values error is 0.517% for surface roughness and 1.181% for cutting force. The optimization using DFA and TOPSIS reported optimal depth of cut, cutting speed, and feed rate at 0.362 mm, 55 m/min, and 0.113 mm/rev, and at 0.8 mm, 154 m/min, and 0.12 mm/rev, respectively. Ra of 2.594 µm and Pz of 14.258 N by DFA and 3.02 µm and 25.83 N by TOPSIS method have been attained. Moreover, confirmation test suggests that both response parameters (surface roughness and cutting force) are in close alignment with the results from the DFA and TOPSIS.

碱处理香蕉纤维增强聚合物复合材料车削时的表面粗糙度和切削力：压缩空气切削

与传统使用的纤维材料相比，香蕉纤维增强聚合物（BaFRP）复合材料可以确保废物的环保分解并降低成本。本文强调了各种加工约束对表面粗糙度（RA）和切削力（Pz）用于车削经过碱处理的香蕉纤维增强聚合物（T-BaFRP）复合材料。30% 的重量分数可产生令人满意的机械性能。田口正交阵 L25 用于使用 DFA 和 TOPSIS 设计实验和优化。在压力保持在 8 bar 的压缩冷却空气切割条件下进行了实验研究。方差分析表明，切削深度和进给速度是影响表面粗糙度和切削力的最重要因素。表面粗糙度预测值与实验值误差为0.517%，切削力预测值与实验值误差为1.181%。使用 DFA 和 TOPSIS 进行的优化报告了最佳切削深度、切削速度和进给率分别为 0.362 mm、55 m/min 和 0.113 mm/rev，以及 0.8 mm、154 m/min 和 0.12 mm/rev。 。右A2.594 µm 和 Pz通过 DFA 获得了 14.258 N，通过 TOPSIS 方法获得了 3.02 µm 和 25.83 N。此外，验证测试表明，两个响应参数（表面粗糙度和切削力）与 DFA 和 TOPSIS 的结果非常一致。
