Motion synchronization between tool in X direction and principal axis rotation was controlled by electronic gearbox in cam turning. And profiling mechanism could be superseded by servo tool-holder. Linear motor direct drive servo tool-holder was designed, and host-slave control system with PC and DSP was developed for the require of high-speed and realtime servo. The technical process was analyzed in cam turning. Servo tool holder with tool swinging and principal axis variable rotate speed were presented to keep constant cutting angle and speed.

将电子齿轮箱用于凸轮车削加工系统的传动，以伺服刀架取代了传统加工的靠模装置，实现了刀具X方向直线运动与机床主轴转动的同步控制；设计了直线电机直接驱动的伺服刀架及基于PC与DSP构成的上—下位机控制结构，采用DSP进行实时控制以满足高速伺服需要；对凸轮加工过程的工艺特点与恒角度、恒速度车削进行研究，提出了具有刀具摆动功能的伺服刀架与机床主轴变转速运动方案。

In this example,human are involved only when they take output of a program,which is usually a strip of punched paper tape,mount it on the machine's input device,and start up the machine.

在该例中，人要做的仅仅是取出程序--通常是窄窄的穿孔纸带，然后再将其安装到机床的输入设备上，并启动机床。

CNC face milling and drill centres hole machine （Referred to as CNC milling fight machine ）,machine is mainly used for shaft parts batch and mass production, miling shaft at both ends 、 drilled the centers hole and turning one end of cylindrical axis, configured SIEMENS 802C CNC system , is controled by three axis, that is, the left X-axis spindle box movement, Y Right-axis spindle movement, Z-axis hydraulic self-centering jig up and down movement, according to the procedure to complete part of the auto-processing, processing of high precision and high efficiency.

数控铣端面钻中心孔机床，机床主要用于轴类零件成批和大批量生产，铣削轴的两端面钻中心孔并可套车轴一端的外圆，配置SIEMENS 802C数控系统，三轴控制，即X轴左主轴箱运动，Y轴右主轴运动，Z轴液压自定心夹具上下运动，按程序完成零件的自动加工，加工精度高、效率高。

Based on analyzing the components and control of the servo-system of the NC machine tools, this paper studies the methods for setting parameters in each loop to guarantee the performance of the machine tools.

本文在分析了数控机床交流伺服系统组成、控制的基础上，研究了各环节的参数设定方法，以保证机床达到良好的运行状态。

The servo-system is an important part in the CNC machine.It decides the precision of the machine and the speed always.

摘 要：伺服系统是数控机床的重要组成部分，数控机床的精度和速度指标等往往由伺服系统决定。

The engine bed also is equipped with the interconnection,the tool rest auto-feed and the rapid traverse interconnection,the lathe bed both sides skip distance cushion which the hydraulic ressure clamp system,the abnormal cutting traveling schedule stops immediately and so on each kind of safety device,guarantees the operator and the engine bed movement safety.

机床还设有液压夹紧系统，失常切削行程立即停止的联锁、刀架的自动进给与快速移动的联锁、床身两端的越程缓冲等各种安全保护装置，以保证操作者和机床运行的安全。

"Crawlirg" can be found in the installation and adjustment of precision machine tools, such as slideway grinder ,and as a result, the working precision is severely affected.

导轨磨床等大型精密机床在安装调试时工作台运动常常会产生"爬行"现象，它严重地影响机床的工作精度。

At present the engine bed profession market competition extremely isintense, proposed to the engine bed precision and the efficiency ahigher request, the slotter main body organization design is in theslotter design most important topic.

目前机床行业市场竞争十分激烈，对机床的精度和效率提出了更高的要求，插床主体机构的设计是插床设计中的首要课题。

The converse method is used to determine the parameters in the design of the parallel machine tool,which allows the use of maximum range of machine varibales(e.g.swinging angle of spherical bearng)within their limits.

机床设计参数的确定采用逆向设计法，充分利用了已有机床部件的极限参数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
