摘要：微细立铣刀的设计制造是微细铣削的关键技术之一。微细立铣刀通常由超硬材料加工制造,采用电火花线切割加工技术加工聚晶金刚石(PCD)微细立铣刀是其加工制造方法之一。着重介绍了PCD微细立铣刀的设计与制造:首先,设计了具有特定刀刃形状的PCD微细立铣刀,并采用有限元方法对其进行优化分析;其次,采用电火花线切割加工技术制造PCD微细立铣刀。

摘要：Based on the study of existing typical micro-milling tools and the actual demand for micro-milling tools, the P3 design principle and design flow for ultra-hard micro-milling tool were introduced to give basic guidance for the optimization of micro-milling tools. Then, according to the P3 design flow, the manufacturing process of polycrystalline diamond(PCD) micro-milling tool was proposed, and the PCD micro-milling tool with diameter of 0.5 mm was developed. Finally, the micro-milling test on the slot was carried out to study the milling performance of PCD micromilling tool.

摘要：采用金刚石砂轮对单晶金刚石微型刀具进行了刃口机械刃磨试验,利用莱卡光学显微镜观察了单晶金刚石刀具刃口和表面形貌,以研究不同参数对磨削过程的影响,通过优化相关参数来获得更好的单晶金刚石微型刀具并提高刃磨效率。试验选择砂轮粒度、磨削速度以及进给速率作为刃磨参数。通过正交试验设计,比较磨削力、刃口半径和表面形貌,从而筛选出最优参数。试验得出小粒度砂轮、较高磨削速度和中等进给速度可以得到较好的刃磨结果。
