| 摘要: |
| 为了研究聚晶金刚石高速铣削钛合金时的切削温度的影响因素,揭示切削温度的变化规律,进行了切削温度试验.采用2k因子试验设计,找出对切削温度有重要影响的主影响因素及交互影响因素;利用均匀设计试验,分析主影响因素及交互影响因素对切削温度的影响规律;建立切削用量与切削温度之间的非线性数学模型.试验结果表明:聚晶金刚石刀具高速铣削钛合金时,切削速度和切削宽度之间的交互作用对切削温度有显著影响,切削温度与切削用量间存在非线性特征规律,切削速度对切削温度的影响随切削宽度的变化而变化.研究结果有助于指导钛合金高速铣削加工,优化高速切削工艺及建立高速切削数据库. |

| Abstract: |
| To study the variation of cutting temperature in high-speed milling of titanium alloy with polycrystalline diamond,factorials design and uniform design were applied to the cutting temperature experiments.The main effects and interaction effect which have significant influence on cutting temperature were found out by factorials design.By using uniform design,the influence law of main effects and interaction effects on cutting temperature were investigated.Nonlinear mathematical model on the relationship between cutting parameters and cutting temperature was established.The results show that under high speed milling,the interaction effect between cutting speed and width of the uncut chip is significant.The relationship between cutting temperature and cutting parameters is nonlinear,and the effect of one cutting speed on cutting temperature changes with width of the uncut chip. |
