Abstract

In this article, the neem wood plastic composite material has been fabricated by mixing neem wood saw powder with polypropylene (PP) matrix by injection molding method to study the machining characteristics of the abrasive water jet machining process. The volume percentage of neem wood saw powder, the volume percentage of additive agent talc mixed with PP matrix (A), table traveling speed (Ts), and water-jet pressure (Wp) have been considered as process parameters. The experiments were conducted and analyzed to predict the optimum parameters setting for surface roughness (SR) and kerf angle (KA) using the Taguchi method. It was observed that KA and SR have been greatly impacted by the percentage of neem wood saw powder, table traveling speed, and water-jet pressure. The SR and KA were minimized by reducing the percentage of neem wood powder, table traveling speed, and water-jet pressure. The SR has been decreased by adding talc agent, conversely, the KA has been increased. The concurrent optimum process parameters setting to minimize both SR and KA had been estimated by the weighted product method (WPM). The predicted results from Taguchi and WPM had been verified by microscopic analysis and confirmation experiments.

磨料水射流加工印楝木塑复合材料的试验研究

本文采用注射成型的方法，将neem木锯粉与聚丙烯（PP）基体混合，制备了neem木塑复合材料，研究了磨料水射流加工工艺的加工特性。neem木锯末的体积百分比、添加剂滑石与PP基体的体积百分比（A）、工作台行进速度（Ts）和水射流压力（Wp）被认为是工艺参数。利用田口方法对表面粗糙度（SR）和切口角（KA）的最佳参数设置进行了实验和分析。结果表明，印楝木锯末用量、工作台行进速度和水射流压力对KA和SR有很大影响。通过降低印楝木粉的百分比、工作台行进速度和喷水压力，将SR和KA降至最低。通过添加滑石剂降低了SR，相反，KA增加了。通过加权乘积法（WPM）估计了同时优化工艺参数以最小化SR和KA。田口和WPM的预测结果已经通过微观分析和验证实验得到了验证。
