ZL109硅铝合金车削加工表面质量研究
|
摘要
采用硬质合金和聚晶金刚石刀具,借助单因素试验对柴油机活塞材料ZL109硅铝合金车削加工过程进行研究,以期获得最佳的切削参数和提高加工表面质量。试验以粗—精加工工艺代替粗—半精—精加工工艺,研究粗—精加工工艺下的加工质量。研究表明,ZL109硅铝合金切削加工的最佳切削参数组合为切削速度v=300m/min,切削深度a_p=0.2mm,进给量f=0.05mm/r。合理选择切削参数可简化加工工艺,提高生产效率和降低生产成本。
The cemented carbide tool and polycrystalline diamond tools are used to study the turning process of diesel alloy piston material ZL109 by single-factor experiments,which aims to obtain the best cutting parameters and improve the surface quality.The experiments investigate the roughing-finishing process instead of the roughing-semi-finishing-finishing process,and evaluated the machining quality under the process.The results indicate that the best cutting parameters of cutting aluminum-silicon alloy ZL109 are cutting speed v=300 m/min,cutting depth a_p=0.2 mm,feed rate f=0.05 mm/r.Choosing the favorable cutting parameters can simplify the machining processes,increase production efficiency and reduce production cost.
