P113Numerical controlNumerical control of machine tools may be defined as a method of automation in which various functions of machine tools are controlled by letters, numbers and symbols. Basically a NC machine runs on a program fed to it. The program consists of precise instructions about the manufacturing methodology as well as the movements. For example, what tool is to be used, at what speed, at what feed and to move from which point to which point in what path, all these instructions are given. Since the program is the controlling point for product manufacture, the machine becomes versatile and can be used for any part. All the functions of an NC machine tool are therefore controlled electronically, hydraulically or pneumatically.In NC machine tools one or more of the following functions may be automatic:(1)Starting and stopping of the machine tool spindle.(2)Controlling the spindle speed.(3)Positioning the tool tip at desired locations andguiding it along. Desired paths by automatic control of the motion of slides.(4)Controlling the rate of movement of the tool tip.(5)Changing of tools in the spindle.Initially the need of NC machine was felt for machining complex shaped small batch components as those belonging to an aircraft. However, this spectrum currently encompasses practically all activities of manufacturing, in particular capital goods and white goods. Thus the range covered is very wide. Besides machining with which we are concerned in this book, NC has been used in a variety of manufacturing situations. The majority of applications of NC are in metal cutting machine tools such as milling machines, lathes, drilling machines, grinding machines and gear generating machines. Beside a number of metal forming machine tools such as presses, flame cutting machines, pipe bending and forming machines, folding and shearing machines also use NC for their program control. The inspection machines called Co-ordinateMeasuring Machines are also based on NC. Lastly the robots basically may be material handling units, but their control principles are very close to the NC. Besides these applications listed for manufacturing, other applications such as filament winding or assembly machines based on the NC principles can also be seen in the industry.NC machines have been found suitable for the following:(1)Parts having complex contours, that cannot bemanufactured by conventional machines tools.(2)Small lot production, often for even single jobproduction, such as for prototyping, toolmanufacturing, etc.(3)Jobs requiring very high accuracy andrepeatability.(4)Jobs requiring many set-ups and/or when theset-ups are expensive.(5)Parts that are subjected to frequent designchanges and consequently require moreexpensive manufacturing methods.(6)The inspection cost, which is a significantportion of the total manufacturing cost.One or more of the above considerations would justify the processing of a part by an NC machines tool.数控数控机床可以被定义为一个自动化的方法，其中工具机的各种功能的控制由字母，数字和符号。

Figure 1.8 shows generalpurpose machine tools used for traditional machining in chip removal and abrasion techniques. Typical examples of general-purpose machine tools include turning, drilling, shaping, milling, grinding, broaching, jig boring, and lapping machines intended for specific tasks. Gear cutting and thread cutting are examples of special-purpose machine tools. During the use of general- or special-purpose manual machine tools, product accuracy and productivity depend on the operator’s participation during operation. Capstan and turret lathes are typical machines that somewhat reduce the operator’s role during machining of bar-type or chucking-type WPs at higher rates and better accuracy. Semiautomatic machine tools perform automatically controlled movements, while the WP has to be hand loaded and unloaded. Fully automatic machine tools are those machines in which WP handling and cutting and other auxiliary activities are performed automatically. Semiautomatic and automatic machine tools are best suited for large production lots where the operator’s interference is minimized or completely eliminated, and parts are machined more accurately and economically.

机械专业英语翻译的方法及技巧PPT课件
❖ 1.2 复杂长句多
▪ 机械工程英语的用词和表达方法都比较严谨准确， 一般一句话要包含几个分句。对于这种复杂长句， 一般要采用压缩主干法进行逐步翻译。
▪ If a hard grade wheel was to be used for grinding a hard material ， the dull grains would not be pulled off from the bond quickly enough ， thus impeding the self dressing process of the surface of the wheel and finally resulting in clogging of the wheel and burns on the ground surface ． ( 如果使用硬砂轮磨削硬的材料，磨钝 的磨粒就不能很快从粘结体上脱落，这样便妨碍砂 轮表面的自休整过程，最终导致砂轮的堵塞并在被 磨表面留下灼斑。 )

机械制造技术英文PPT11
(1) Orthogonal plane reference system 1) The base plane Pr passes through the plane perpendicular to the cutting
speed at the selected point on the cutting edge. The base surface of the turning tool is the plane parallel to the bottom surface through the selected point of the cutting edge, and the base surface of the milling cutter and drill is the axial section of the tool.
3) The orthogonal plane Po passes through the plane selected by the cutting edge and is perpendicular to both the base plane and the cutting plane.
Orthogonal plane reference system
Basic knowledge of tool cutting
一、 The composition of the cutting part of the tool
• There are many types of tools used in metal cutting, and their shapes and uses are different. Among them, the turning tool is a basic tool that is widely used. Other tools can be regarded as the evolution or combination of turning tools. The outer turning tool is taken as an example to illustrate the basic concept of the tool composition and the geometric parameters of the cutting part of the tool.

2. Screw clamping mechanism
Using the screw directly clamping or using the combination of screw and other components to achieve the clamping mechanism, We are called the screw clamping mechanism. Screw clamping mechanism has simple structure, large strength and good self-lock, It is very suitable for manual clamping. It is characterized by slow clamping action, so it is less used in maneuvering clamping.
