There are two kinds of cuts in machine- shop work called, respectively, the "roughing cut" and the "finishingcut".
机械工厂的切削加工有两种，分别称为“粗切削”和“精切削”。

Generally speaking, bars of steel, forging, castings, etc. are machined to the required shape and size with only one roughing and one finishingcut.
一般地说，钢质棒料、锻件、铸件等只经一次粗切削和一次精切削即可达到所要求的形状和尺寸。

A new WEDM (Wire Electrical Discharge Machining) technology for finishingcut has been developed, in which gas has been used as a dielectric instead of water.
