什麼是 compliance 目前在阅读一"finishing tools"的介绍 以下这段英文我不懂该如何翻译 The spindle is radially compliable while the necessary pressure is monitored by program control. The weight can be completely zero by switching the compliance air. The compliance is effected by a parallelogram mechanism that assures that the movement is parallel and that the tool angle does not change.
