Cutting experimental study of new material tools for austenitic manganese steel riding wheel 煤矿大型高锰钢托轮的新型刀具切削试验研究
Considering the die - cavity roughing being a 2 . 5d cutting , a novel cutting force surface model is created based on orthogonal cutting tests 鉴于模具型腔粗加工常采用2 . 5维加工,提出一种通过正交切削试验建立切削力曲面模型用于模具型腔粗加工进给率优选的新策略。
In order to analyze the effect of structure of hypereutectic al - si alloy on its machinability , the cutting test to two hypereutectic al - si alloys which have the same chemical composition but different structures is made and their cutting mechanism is studied 为分析过共晶铝硅合金组织对其切削加工性能的影响,对两种化学成分相同但是组织结构不同的过共晶铝硅合金进行了切削试验研究并探讨了其切削机理。
On the base of tests , this paper discusses theoretically and analyses practically including the following parts by test : choosing the project of auto grafting ; studying and designing crushing resistance device and test , designing and theoretical analysis of the cutting mechanism , setting up mathematics model to optimize the parameters of the half - rotation cutting mechanism with matlab6 . 5 language ; studying on secant and smooth cutting , single - sustained cutting and double - sustained cutting , finding the relation between cutting and fiber orientation of young plants 本课题主要研究机械嫁接法的选择;开发研制模拟切削试验装置和抗压伤试验装置及其配套装置;苗木物理机械性能试验研究;运用最新的工程分析软件matlab6 . 5对切削机构的参数进行优化;模拟切削正交试验分析和spss软件回归分析;改进设计夹持机构和设计新型的半旋转切削机构。
