Question

5) Tool and work holding devices.
6) A structure linking and aligning the individual units together， so that the tool and work are maintained in a controlled relationship(1).
Power units
There are three types of power units required：
1) For driving the main spindle (cutting speed).
2) For driving the saddle or carriages (feed)
3) Providing power for ancillary services.
The motors are of two kinds:
1) Electrical. Alternating current (AC)， Direct current (DC) or stepper motors.
2) Fluid. Hydraulic or pneumatic motors.
Speed control units
The variation in speed of DC motors is obtained by varying either the armature voltage or the field voltage. The output signal generated by the pulse generator or tacho-generators is compared with the input value of the voltage to be applied to the DC motor， which represents the desired speed， and any difference between these voltages is used to vary the voltage to obtain the required speed.
Control of translational (line) movements
A slideway is used to control the direction， or line of action， of the translational movement of the carriage or table on which the tools or work are held.
As a safety measure， microswitches are positioned near the ends of the slideway. If the microswitches are activated (closed) by contact with the carriages， the power to the feed motors will be switched off. This will prevent the carriages traveling too far and striking the leadscrew bearing end housings， or the nut screwing off the leadscrew(2).
Slideways commonly used on machine tools have a number of different forms， such as cylindrical， vee， flat and dovetail.
Control of rotational movements
In a similar way as the translational movement of the carriage is controlled by the slideways， rotational movements of spindles are controlled by circular bearings. The accuracy of the roundness of the rotation is dependent on the quality of the bearings.
Actuating mechanisms
Of all the constructional that make up a numerically controlled machine tool， the efficiency and responsiveness of the actuating mechanisms (the drive unit) have the greatest influence on the accuracy of the work produced.
The actuating mechanisms for the carriage for tool or work found on numerically controlled machine tools are: screw and nut； rack and pinion； and ram and piston.
Tool holders
The tools must be held securely within the holder and supported sufficiently to prevent the tools twisting or bending under the action of the cutting force. A main operational consideration to be given to the type of tool holder used is that the tool change should be capable of being carried cut as quickly as possible. This is because， although it is essential to change tools， time spent on carrying cut these operations does nothing positive to the work； only when work material is being removed ， or there is any change in the shape or size of the work， is any benefit being obtained(3).

Answer 1

5)的工具和设备工作持有。
6)结构和调整单元连接在一起,使工具和工作在一个受控的关系保持(1)。
发电机组
有三种类型的发电机组要求:
1)驱动主轴(切削速度)。
2)在鞍或车厢开车(喂)
3)为辅助服务提供能量。
发动机有两种:
1)电器。交流电(AC)、直流电(DC)还是步进电机。
2)的液体。液动或气动马达。
速度控制单元
在速度的变化得到直流电机电枢电压变化或者或场地电压。输出信号的脉冲发生器产生的或tacho-generators对比输入电压值被应用到直流电机,代表着希望的速度,以及任何区别用来改变这些电压的电压得到所需的速度。
翻译(线)的控制动作
一个导轨是用来控制方向,或线的动作、平移运动的马车或桌子上举行的工具或工作。
作为安全措施,生产是定位在导轨的两端。如果生产(关闭)被激活接触的车厢里的乘客,有权力去饲料电机将成为关闭。这将防止车辆太远和打击旅行结束leadscrew轴承外壳,或螺母螺丝从leadscrew。
常用机床导轨上有多种不同的形式,如圆柱、钨钢、公寓、相吻合。
旋转运动控制
以类似的方式为平移运动的马车控制的导轨、旋转动作控制主轴循环轴承。圆度的准确性的转动是依赖于质量的轴承。
工作机制
所有的建筑构成一个数控机床、效率和适应性的工作机制(驱动单元)有最大的影响所做的准确性。
工作机理的运送工具或工作上发现的数控机床是:螺丝,螺母,齿条和齿轮、公绵羊和活塞。
工具持有人
工具必须被安全地在持有人,足以防止工具支持、弯扭作用下的切削力的。一个主要的运作考虑给予持有者使用类型的工具是模具的更换应该有能力在进行切割,越快越好。这是因为,虽然有必要改变工具,花时间进行削减这些操作不积极工作;只有当工作资料已经被删除,或有任何变动的形状或大小的工作,获得了利益(3)。
