Experiments were implemented to obtain the motor power and AE signals under different cutting parameter condition(cutting velocity, feed velocity and cutting depth), tool wear and breakage conditions.
采用机床主电动机功率法和声发射（AE）法来获取切削过程中发出的刀具磨损和破损信号，建立了刀具状态试验系统。
Through collecting vibration signal and analyzing it in the frequency domain in the condition of changing parameter cutting, a single self power spectrum is hard to detect tool breakage effectively.
在变切削参数的加工工况下，通过对振动信号的采集和频域处理，发现采用单一的自功率谱方法难以有效检测出刀片破损。
Can apply thousands of pounds tension to metal stock or welds in excellent condition, causing breakage, yet NO TOOL MARKS are left on the finish.
能在良好的条件下运用数千磅的压力于金属盘或焊接处，导致破坏，但在完成后却没有留下任何痕迹。
The causes of the breakage of piston ring in vessel are analyzed according to the working condition and force circumstance. Some precaution and emergent measures are provided.

This could mean a hot (heart) condition, or there could be a hole or breakage (blockage) in a lung.
这可能意味着心脏出现状况，肺部可能出现肺穿孔或肺阻塞。
Valve Breakage. Any condition that causes the valve to overheat or to be subjected to heavy pounding (as from excessive tappet clearance or from detonation ) may cause valves to Break.
气门过热或遭受重载（气门杆间隙过大或爆裂）均可造成气门破裂。
Valve Breakage. Any condition that causes the valve to overheat or to be subjected to heavy pounding (as from excessive tappet clearance or from detonation ) may cause valves to Break.
