Simulation of micro-milling process is conducted using finite element method. During modeling, the Johnson-Cook's coupled thermal-mechanical model was employed as workpiece material model, the Johnson-Cook s shear failure principle was adopted as work piece failure principle, and the coupled thermal-mechanical hexahedron strain hybrid modules and adaptive grid were used to remesh the workpiece's elements. The friction between the tool and workpiece obeys the amended coulomb's law that combines with the sliding friction and the adhesive friction.

CPM-3V will likely always be my favorite, but the choice of stainless might change depending on where my friend, Scott Devanna, who has managed the knife steel business at Crucible ends up working.

CPM-3V 也可能将一直是我的最爱，但对不锈钢的选择则可能会跟着我朋友SCOTT DEVANNA的去向而改变，他过去一直主管钳锅公司刀具专用钢材产成品业务。

A theoretical model for calculating the cutting angle with different crystal planes, orientations and tool orthogonal rakes are described in this paper. It is built with the ultra-precision cutting model by the principle of the maximum specific energy of shear deformation and the mechanism of change of the shear modulus with...

本文利用剪切变形比能最大及单晶材料不同晶面晶向剪切弹性模量不同的原理，结合超精密切削模型，从理论上计算出不同晶面、不同晶向及不同刀具前角超精密切削条件下的剪切角，得到其在不同切削条件下的变化规律，并由此解释了切削加工中由KDP晶体各向异性所导致的工件表面粗糙度的各向异性。
