一、概述与普通加工相比，实现微细加工有两个必要条件：较高的成形运动精度和微小的切削深度。一般认为，加工成形运动精度由机床来保证，切削量微小化就成了评价微细加工方法优劣的关键。机械切削加工中切削深度的微小化则由减小刀具的刀尖半径等手段来保证。为此在精微切削
First, an overview Compared with the ordinary processing, there are two necessary conditions to achieve micro-processing: high precision forming motion and a small depth of cut. It is generally believed that the accuracy of machining forming motion is guaranteed by the machine tool. The miniaturization of the cutting amount has become the key to evaluate the advantages and disadvantages of the microfabrication method. Mechanical cutting machining depth of the miniaturization by reducing the tool tip radius and other means to ensure. To this end in the subtle cutting
