1.Toolsetting and installing of coordinate system of workpieces are important tasks while machining numerically controlled machines.
数控机床加工时,对刀及工件坐标系的设定是一项重要工作。
2.The optimeter is widely used to precisely measure external size of workpiece by comparison with a gauge block or standard part.
本仪器是一般是用标准器（如块）以比较法测工件的尺寸。
3.The machine can finish the moulding and processing of heteromorphosis iron craftwork with good consistency, and can process parts in batches and high efficiency.
本机可以完成异形铁艺工件的一次加工成形，铁艺工件一致性好，可实现批生产，工作效率高。
4.The system uses PLC procedure control, start-up, forward or backward soldering gun, arc starting, workpiece circumgyration, etc full welding process all can complete automatically.
系统采用PLC程序控制，启动、进退枪、引弧、工件旋转等焊接全过程均能自动完成。
5.Material removal by machining involves interaction of five elements: the cutting tool, the toolholding and guiding device, the workholder, the workpiece, and the machine.
材料的切削与5个因素有关：刀具，刀具的夹具和导向装置，工件的夹具，工件和加工机器。
6.Based on machine kinematics and cutting theories, the simulating method for the generation of three-dimensional surfaces in face turning and flycutting of SPDT is studied.
基于机床运动学和切削理论对刚石加工时的工件端面切削及“飞切”加工进行了仿真建模。
7.It is not only meet with precision of the outface of parts,but also can assure the precision of the inface of parts.And it is developped the traditional process mandrel spinning.
