1、The three factors of cutting include cutting speed, feed and the depth of cut.切削用量三要素包括切削速度、进给量和 （或叫吃刀量）。

2、 Feed is concerned with the distance of the cutting tool’s movement relative to the workpiece at the feeding direction.进给量是刀具与工件在进给方向上的相对位移量。

3、The world is made up of matters. There are so many different types of materials in the world.世界是由物质构成的。世界上又有如此之多的材料。

4、In fact ,a robot is basically a highly automated machine that is created to duplicate one or more physical capabilities of a person.实际上机器人基本上是一种高度自动化的机器，它可以模仿人的一个或多个身体的动作

5、Machinery manufacturing technology is the most important technology appliedinprocessing operation。制造技术是应用于加工工序的最重要的的一门技术。

6、production operation is the processing step in which one operator process one Workpart at one orkstation。生产工序是一个操作者在一个工作地点对一个工件进行的加工。

7、Metal cutting technology is the technology which is concerned with utilizing various processes to remove material from the workpart and achieve final desired gometry.金属切削中，刀具和工件必须通过加工过程中的相对运动来获得所需的几何形状。

8、The programe is stored in battery-backed memory and/or EEPROMS.程序通常存储在随机存储器（备用电池）或可擦写、可编程只读存储器中。

9、In fact, a robot is basically a highly automated machine that is created to duplicate one or more physical capabilities of a person.实际上，机器人基本上是一种高度自动化的机器，他可以模仿人的一个或多个身体动作。

10、The rubber is another major category in nonmetal materials. It can be divided into natural rubber and synthetic rubber according to the source of raw materials. Because of its high elasticity and electric insulation, rubber can be used in making tires, shock absorbers, airproof loops and electric insulation.橡胶是非金属材料的另一大类。根据原材料的来源不同，它能分为天然橡胶和合成橡胶两类。橡胶因为具有高弹性和绝缘性，常被用来制作轮胎、减震器、密封圈和电绝缘材料。

11、 CNC technology is being used on all types of machine tools, from the simplest to the most complex.从最简单道最复杂的机床都会用到数控（CNC）技术。

12、Tool materials may be either metal or nonmetal. High-speed steel and carbide are the most widely used metal tool materials.制造刀具材料的材料既有金属材料也有非金属材料。高速钢和硬质合金是最广泛应用的金属刀具材料。

13、Electric system is a very important unit, which is used in the field of electric engineering and mechatronics engineering.电子系统是电子工程，机电工程领域涉及的一个重要部分。

14、The materials removed from the workpiece are called chips. Chips will have different shapes such as continuous chips, segmented nonhomogeneous chips and discontinuous chips according to different part materials, processes, and other variables.从工件上切下的废料称为切屑。根据零件材料、加工方法及其它变量的不同，切屑会形成不同形状，如带状切屑、节状切屑和崩碎切屑

15、 A bus （or omnibus or coach）， which is a large public conveyance designed to carry a large number of passengers and sometimes additionally small amounts of cargo.公共汽车（或公共马车，长途汽车）是一种大型的公共运输工具，用来搭载大量的乘客，有时也附加的运输少量的货物。

16、In metal cutting,tools and workparts must have certain relative movements during processing in order to achieve geometry needed.The movements include main movement and feed movement.金属切削技术是利用各种不同的加工方法去除工件材料，获得最终所需的几何形状。
