工件

Toolsetting and installing of coordinate system of workpieces are important tasks while machining numerically controlled machines.

数控机床加时,对刀及件坐标定是一项重要作。

The optimeter is widely used to precisely measure external size of workpiece by comparison with a gauge block or standard part.

仪器是一般是用标准器（如量块）以比较法测量件尺寸。

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.

统采用PLC程序控制，启动、进退枪、引弧、件旋转等焊接全过程均能自动完成。

The machine can finish the moulding and processing of heteromorphosis iron craftwork with good consistency, and can process parts in batches and high efficiency.

机可以完成异形铁艺件一次加成形，铁艺件一致性好，可实现批量生产，作效率高。

Material removal by machining involves interaction of five elements: the cutting tool, the toolholding and guiding device, the workholder, the workpiece, and the machine.

材料切削与5个因素有关：刀，刀和导向装置，件，件和加机器。

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单点金刚石加时件端面切削及“飞切”加进行了仿真建模。

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.

该艺不仅能满足件外表面精度要求,而且还能保证内表面精度要求,是对传统芯模旋压艺完善。
