为研究钻削加工过程中不同刀具对小孔径高精度孔表面质量的影响,结合工艺研究优化方案,选用枪钻和麻花钻2种刀具类型,运用Abaqus有限元仿真软件在相同的边界条件及参数下,建立小孔径高精度孔的加工模型,并对加工过程进行模拟仿真。结果表明,相对麻花钻而言,枪钻切削力、表面粗糙度、圆柱度误差较小,尺寸精度较高。
In order to study the influence of different tools on the surface quality of high precision hole with small aperture in the drilling process, two kinds of tool types, gun drill and twist drill, were selected in combination with the process optimization program. Abaqus finite element simulation software was used to simulate the influence of the same boundary conditions and parameters Under the establishment of small aperture precision hole processing model, and the process of simulation. The results show that, relative to the twist drill, the gun drill cutting force, surface roughness, cylindrical error smaller, higher dimensional accuracy.
