急停

定义

紧急停止机床的安全功能。

以前置元数据中的定义作为统一语义，并在装夹、加工与检验环节保持一致。

公式/规则

• 急停属于安全功能：先停止运动，再保留现场并排除危险后才能恢复。
• 每次急停都应按异常事件处理，先确认原因，而不是只把它当作继续生产的按钮。

典型范围

• The acceptable operating window is zero avoidable E-stop events during normal production.
• Any recurring E-stop on the same job should trigger a formal root-cause review.

现场场景

• After an E-stop, confirm hazard removal, axis clearances, and restart sequence before releasing the machine.
• Record the trigger condition so the same unsafe sequence is not repeated on the next shift.

常见错误/排障

• If E-stop events are frequent, review guarding, interlocks, and operator sequence instead of normalizing the risk.
• If restart behavior is unclear, return to the recovery checklist and confirm every energy state before jogging axes.
