摘要
对不锈钢细长轴进行车铣复合切削加工试验,重点研究了工件转速、铣刀转速、切削厚度等因素对工件加工表面粗糙度的影响,并对试验参数进行了优化。在优化的切削参数下,以尺寸精度为评价指标,对长径比较大的不锈钢细长轴进行正向、反向车铣加工试验研究。结果表明,反向车铣切削加工细长轴,能够获得较好的表面质量和较高的加工精度;在较优的工艺条件下,可获得表面粗糙度值为Ra0.458μm,尺寸精度优于0.015 mm的Φ9mm×300mm的不锈钢细长杆。
Turn-milling machining of stainless steel slender shaft was carried out. Influences of the rotate speed of workpiece, milling speed and milling thickness to the surface roughness of the stainless steel workpiece were analyzed based on the experiments. With the optimal processing parameters, the forward turn -milling and reverse turn -milling of stainless steel slender shqft with was conducted taking the dimensional accuracy as assessment index. The results show that good surface quality and high processing precision can be achieved by the turn-milling machining technology. Under the optimum process conditions,φ9mm μ300mm stainless steel slender shaft with the surface roughness values Ra0.458μm, the dimensional accuracy better than 0.015mm can be obtained.
