Fixture of many types, by the use of machine type can be divided into fixture lathe, milling machine fixture, drilling fixture. Jig Boring Machine, processing centers and other fixture fixture.

机床夹具的种类很多，按使用机床类型分类，可分为车床夹具、铣床夹具、钻床夹具、镗床夹具、加工中心夹具和其他夹具等。

In the following section,we discuss the various machining operations that can be performed on a conventional engine lathe.

在以下部分中，我们将讨论各种机床操作，这些操作均是在传统电动机床上进行的。

It raises overall design scheme of the machine tool, adopts model association structure. The machine tool adopts frame structure and five axels CNC, and it can process the optical elements with the diameter of 500mm.

Jones提出的卷积原理，建立去除函数模型和驻留函数模型，用此两个数学模型表示材料去除量函数；以机床性能要求为前提，进行计算机控制小工具抛光机床的结构设计。

Model KTX150 NC cam milling machine is a special machine that can process camshaft,also any cam of flat and cylinder surface.the machine is beautiful and stylish in design,simple in constuction,excellet in performance.the machine is using current NC system of three cooadinate axises when no copying,it can be used for different kinds of cam part's semi-precise procession by loading automacically.

Insulation and sheathing shall be provided over all exhaust piping including the silencer.

机用虎钳是一种机床附件（图2），又称平口钳，一般安装在铣床、钻床、牛头刨床和平面磨床等机床的工作台上使用。

Along with the numerical control line cutting engine bed application unceasing expansion, engine bed itself also arrived the unceasing development.

摘要随着数控线切割机床应用的不断扩大，机床本身也得到了不断的发展。

Servo motor with outage brake is adopted in the braking device,adding an external outage brake on the plumb shaft of CNC machine,and the external outage brake is fixed on the upside of ball screw.

数控机床垂向滚珠丝杠制动装置采用带失电制动器的伺服电动机，再在数控机床的铅垂轴上，增加一个外置失电制动器。

Machine Tool for automatic, manual-type dual purpose, manually type on the basis of automatic but removal the automatic feeding devices and installed the carding device (this device is mainly applied to plants and animals hair) and manual output parts in the same machine tool, the specifications of iron sheet brushes within 2.2 mm ~15mm can be done, the shearing height can be controlled within 13 mm ~ 260mm (suitable for plants and animals hair), automatic feed, 16 gear speed settings, the length of products can be set at will, automatic punching shear, the tolerance can be controlled within ± 0.2mm, with the characteristics of broad applicability, disassembling convenient, flexible, and a multipurpose.

机床为全自动、手动型两用，手动型在自动的基础上拆除自动下毛毛箱装置，安装随机的梳毛装置（此装置主要适用于动植物毛）和手动排毛部件可在同一机床上生产底宽2.2mm～15mm规格的铁皮刷，剪毛高度可自由控制在总高13mm～260mm之间，自动进料，16档速设置，产品长度任意设置，自动冲剪，冲剪长度能保证在±0.2mm以内。具有适用性广、拆装方便、灵活、一机多用的特点。

This algorithm provides a more continuous feed motion using C2 continuous derivatives and nearly-arc spline parameterization.

该算法采用二阶连续可导的五次样条和近弧长样条参数提高了进给运动的连续性；速度控制算法保证机床在高速运行过程中加加速度的二次连续、加速度、速度和位移与时间关系的高阶连续变化，并且保证在各自的约束范围内，从而使机床的运动平稳，避免产生大的冲击和振动，同时有利于提高加工质量，减少加工时间。

The feed motion is projected into each feed axis, and based on its mechanical model(motor driving torque/force, Inertial force and cutting force), the constraint relationship between feedrate, feed acceleration, and feed drive capabilities and toolpath geometric characteristics is derived. With this constraint model, the acceleration and deceleration of each axis can be limited within its capability.

将进给运动分解到各运动轴，根据机床进给轴的力学(电机驱动力／力矩、进给系统所受的惯性力及切削力)模型，推导了多轴联动加工时进给速度、加速度与各进给轴驱动能力以及加工路径几何特性之间的约束关系，使得加工过程中机床各运动轴的加减速始终处于其加工能力范围内。

I will endeavour to find you some assistance.
