6、Translate the following sentences into Chinese.

●The chain may be located on the side or the top of the CNC machine .these positions

enable tools to be stored away from the spindle and work. This will ensure a minimum of chip interference with the storage mechanism and a maximum of tool protection.

链式矩阵刀库可以安装在CNC机床的侧面或顶部，这种位置可使存放的刀具远离主轴和共建，从而最大限度的减少切削对存刀装置的影响，同时更好的保护刀具。

●Ensure repeatability of a tool :center the tool in the spindle such that the tool’s relation to

the work is repeated every time the tool in used.

保证刀具的重复定位精度：将刀心定位于主轴中心，从而保证每次使用该刀具时其相对于工件位置是可重复的。

●the location of a CNC tool at any time is controlled by a system of XYZ coordinates called

cartesian coordinates .

●任何时候，CNC 刀具的位置都是由一个叫笛卡尔坐标的XYZ坐标控制的。

●In the early days of NC (before computer numerical control), the NC programmer actually

had to know how many rotations of an axis drive motor equated to an inch of linear movement.

在NC发展的最初期（计算机数字控制出现之前），NC 程序员确实必须知道走一英寸直线长时各轴的驱动电动机转多少转。

●Many problems in CNC programming involve finding the Xand Y coordinates of tool

motion based on a given length and angle .these tasks can usually be accompolished by using basic right-triangle trigonometry.
