Mill Optimization
In 1998, prior to running Saw Control full out, the mill had over 600 minutes of snake-related downtime. In 1999, that fell to 173 minutes. And all of this happened in the face of ever increasing feed speeds. "We used to have a maximum speed in the winter of 345 ft/min on a 4.1-in cant, and 355 in summer. Now our entry speed on an 8-in depth ...
