摘　　要：为了寻找到化铣槽液各组分的最佳含量范围,使零件达到稳定化铣侧切率,减少板材铣切厚度差,本研究通过测量对比试片在各组分含量的槽液中铣切壁板的侧切率和均匀度参数来实现。结果表明,当NaOH初始浓度为200g/L、溶解Al 3+为70～110g/L、温度(90±5)℃的技术条件下能够得到肋条偏差Tw±0.75mm、壁厚偏差Ts±0.15mm的较理想的化铣产品。The objective of the work is to find out the optimal range of chemical milling liquor composition, which can lead to a stable chemical milling under cut rate and a decrease in milling thickness difference. This work is conducted to measure and compare the milling under cut and rib evenness through a group of experiments which raring the main material composition in chemical milling liquor. It is indicate that under the condition of NaOH 200 g/L, dessolved aluminum 70 to 110 g/L, temperature （90±5）℃, the rib width difference reach to Tw±0.75 mm,the thick difference reach to Ts±0.15 mm .
