Method and system for controlling punch process noise. |
摘要 |
<p>A method and apparatus for controlling punch press noise in which the noise level produced is monitored by a detector (48) and the press ram velocity is modified in real time to keep the noise level within preset limits. A time weighted average noise level is also controlled by varying the ram velocity for punching operations over a period of operation to maintain a projected time weighted average within a preset limit. <IMAGE></p> |
