摘要
运用DEFORM-3D有限元软件建立了钛种植体表面的切削加工模型,研究了钛种植体表面鳞刺微结构的切削加工工艺过程,通过计算机模拟和试验验证了切削速度、切削深度和刀具前角对鳞刺厚度的影响规律。当选取鳞刺的平均厚度为评价指标,在较低切削速度(20m/min左右)和合适的切削深度的条件下,尽量选择较小的刀具前角(小于5°),可以获得表面具有丰富鳞刺微结构的钛种植体表面。
The cutting model of titanium implant was built by the DEFORM-3D finite analysis soft, then studied on the forming process of scale microstructure, finally simulated and validated the influence rule on scale thickness of cutting speed, cutting depth and tool rake angle. The average thickness of scale was considered as estimate index, on the condition of low cutting speed （about 20 m/min）, suitable cutting depth and smaller tool rake angle（less than 5°） was choosed according with requirement, the surface of titanium implant with a great deal of scale microstructure could be obtained.
