The design of the device using NC Lathe CA6140 control, part of the main transmission system using AC spindle motor and graded by the pulley driven spindle gearbox, through the inverter and gearbox to achieve sub; Feed System used by stepper motor driven ball screw slowdown after campaign vertical feed system through a gear after the ball screw drive, in the horizontal feed system through two gear-driven ball screw; Tool to automatically transfer tool carrier (4-position), thus achieving automatic tool change; by MCS-51 series 8051 data to be dealt with. from the I / O interface stepper pulse output signal to control the feed rate and itineraries; In order to maintain the function of cutting thread, to the outer end of spindle or other appropriate location loaded pulse generator; Lathe will be transformed into Tailstock manually controlled electric Tailstock.

本设计利用数控装置对CA6140普通车床进行控制，主传动系统部分采用交流调频主轴电动机经带轮及分级齿轮变速箱驱动主轴，通过变频器和齿轮变速箱实现分段无级变速；进给系统采用步进电机通过减速后驱动滚珠丝杠运动，在纵向进给系统中通过一级齿轮减速后驱动滚珠丝杠，在横向进给系统中通过二级齿轮减速驱动滚珠丝杠；刀架改为自动转位刀架从而实现自动换刀；通过MCS-51系列8051单片机对数据进行计算处理，由I/O接口输出步进脉冲信号控制进给速度和行程；为了保持切削螺纹的功能，要在主轴外端或其它适当部位装上脉冲发生器；将车床的手动尾座改造成为可控电动尾座。

The form of its locomotion is: first, drive shaft inconjunction with the knife rest going down vertically in a certaindistance, then the magnetic stepping motor works, then the gearwheel group revolving with the shaft and the knife rest. Afterrevolving a circle, the air pressure vat decompresses, then, theshaft and the knife rest resets in the result of the spring.

其运动形式是：通过气压缸将传动轴和刀架打下一个固定距离，然后步进电机开始工作，通过带轮组带动传动轴和刀架作旋转运动，旋转360度后气压缸开始减压，复位弹簧使主轴和刀架复位。

This group displays some of the variety and elegance of this important implement.

阿伊努的刀，除了刀与鞘外，通常会有串上玻璃珠，像舌头一样的短系带，与刀鞘本身紧连，形成一个整体固定在皮带上。

When using the die-cutting tool, be sure to use industry gently rolling shouder strickle blankets up drop every day in order to maintain an adequate amount of lubricant die-cutting knife at the end of shouder hobber and the stone the roller surface clean, and in both form a thin film to improve die-cutting knife at the end of shouder hobber and rolls of anvil wear resistance.

搁置模切刀时，一不退给对峙搁置厂家供答的滚肩刮拭毛毡，每天进取滴适度润滑油，以保留模切刀滚肩与底砧辊暗不天的肮脏，且在两者间变成一层薄薄的油膜，恶化模切刀滚肩与底砧辊暗不天的耐磨损性能。

In the process of moving from single-sustenance to double- sustenance, the angel of body tends to enlarge; in the process of moving from double-sustenance to single-sustenance, the angle of body tends to decrease; when the right leg is kicking on the ice, the center of gravity is just moved to the upper point of fulcrum, which means the center of gravity is vertical to fulcrum, while the left leg starts to kick on the ice when center of gravity completely surpass fulcrum; right knife touches the front ice of the supporting foot, the left knife touches the interior and front ice; small momentum variation coefficient and good effect of momentum move show the rationality of action and abundance of

单支撑阶段向双支撑阶段过渡过程中，躯干角度有增大趋势；右双支撑阶段向单支撑阶段过渡过程中，躯干角度有下降趋势；右腿蹬冰时重心刚好前移至支点的正上方，即重心与支点相垂直，而左腿则是在重心完全超越支点后一段时间才开始的蹬冰；右刀着冰向支撑脚前方下刀，左刀着冰向内侧前方跨出；动量变异系数小，动量转移效果好，反映了动作结构的合理性和能量利用的充分性；目前世界优秀运动员各环节的动量分配比例较以前均有较大幅度的提高；环节动量变异系数遵循着大环节动量变异系数小、小环节动量变异系数大的原则是较合理的。

India, Middle East, there are many kinds of swords with reinforced tip. For example, katar in India, has very sharp and thick tip, made by European steels and the native Damascus steels.

印度，中东一带，也有著很多带有reinforced tip 特性的刀剑，如印度武器中的katar，其尖既厚又锋利，用料有来自欧洲刀剑的钢材（对，就连古文明国度的印度人，也会用欧洲刀剑的钢材），及土产的大马士革钢。

Only hate their marksmanship太臭, for a sudden jump fromthe obstacles to the enemy, I suggest that a knife and stabbed directly up, after all, knife-like power than the power tomuch larger Moreover, knife switch faster pace than the pistol.

只能恨自己的枪法太臭，对于突然从障碍物跳出来的敌人，本人建议拿刀直接上去捅，毕竟刀的威力比手枪的威力要大很多，况且切换刀的速度要比手枪快。
