摘要

LM6合金的磨蚀特性很难加工，因此设计一种允许有效加工的技术至关重要。本文旨在评价进给速度、主轴转速和钻头材料等工艺变量对LM6合金钻孔时推力、表面粗糙度和毛刺高度等响应的影响。采用搅拌铸造法制备了LM6铝合金。在立式加工中心采用L9正交阵列与测力仪进行了试验研究。采用表面粗糙度仪测量表面粗糙度，采用视觉测量系统测量毛刺高度。结果表明，所建立的模型能在给定参数范围内准确估计LM6合金钻孔的推力(TF)、表面粗糙度(SR)和毛刺高度(BH)。

Optimization of drilling process variables using taguchi technique for LM6 aluminium alloy

The abrasive characteristics of LM6 alloys are difficult to machine, so designing a technology that allows for effective machining is essential. This paper aims to evaluate the effect of process variables, namely feed rate, spindle speed and drill material, towards the responses like Thrust force, Surface roughness and burr height when drilling of LM6 alloy. LM6 aluminium alloy was fabricated by the stir casting process. Experiments were conducted using L9 orthogonal array in a Vertical Machining Centre coupled with a dynamometer for measuring thrust force. Surface roughness was found by Surface roughness tester and burr height was measured using Vision Measuring System. The findings show that the created model can accurately estimate the thrust force (TF), surface roughness (SR) and burr height (BH) in LM6 alloy drilling within the parameters examined.
