摘要

本研究的目的是探讨在计算机数控铣床上加工金字塔形状时，工艺参数(刀具直径、壁角和步长)对几何精度的影响。采用田口正交阵列(L9)设计实验工作，并使用Minitab 2017中的ANOVA软件包对实验结果进行分析。结果表明:几何精度随刀具直径和步长的减小而增大，随壁角的增大而增大。发现了两种误差类型:板材弯曲误差(eb)和回弹误差(es)。刀具直径对几何精度的影响最大，其次是壁角和步长。

EFFECT OF PROCESS PARAMETERS ON THE GEOMETRIC ACCURACY OF THE AA1050 ALLOY DURING THE ICREMENTAL FORMING PROCESS

The purpose of this study is to investigate the effects of process parameters (tool diameters, wall angle and step size) on geometric accuracy during forming pyramid shape using computer numerical control (CNC) milling machine. Taguchi orthogonal array (L9) was used to design the experimental work and the results were analyzed using ANOVA package in Minitab 2017. The results shows that geometric accuracy increase as tool diameter and step size are decrease while it increase with wall angle increase. Two type of error was found sheet bending error (eb) and spring back error (es). Tool diameter have the highest effect on geometric accuracy followed by wall angle and step size.
