The turning of a part in a lathe is another example of several forces in action(as shown in Figure 1).As the work revolves and the cutting tool moves into the work,the wedging action of the cutting edge produces a shear force.This force causes the metal to seem to flow off the work in the form of chips.If this workpiece is held between the centers of the lathe,the centers exert a compressive force against the work.The lathe dog which drives the work tends to produce a shearing force.The pressure of the cutting tool against the work produces tension and compression,as well as a shearing action.

Considerable attention is given to the action of centrifugal force in grinding wheels.That is,the bonding agent that holds the abrasive particles on the wheel must be stronger than the forces which tend to make the revolving wheel fly apart at high speeds.For this reason,the speed of a grinding wheel should not exceed the safe surface speed limit specified by the manufacturer.Centrifug

车床的转动工件也是多股力量一起作用的另一个例子（如图1所示）。当切削工具移至正在旋转的工件时，刀刃的楔劈作用就产生剪力。该股力量使金属成碎屑状从工件溢放出来似的。如果工件是被夹在车床中心之间，这些中心会对工件施加压缩力；而驱动工件的车床轧头趋于产生剪力。切削工具向工件所施加的压力产生了拉伸、压缩以及剪力作用。
