Example 6: Cut speed increased from 1800 mm/min (72 in./min) to 2080 mm/min (82 in./min)
In this example, the top lines are not bad. However, the bottom lines are trailing and inconsistent. Also, there is a lack of
oxygen at the bottom of the cut.

Example 7: Cut speed decreased from 1800 mm/min (72 in./min) to 1016 mm/min (40 in./min)
In this example, the cut is very consistent from the top to the bottom. However, decreasing the cut rate reduces
productivity. The operator needs to reach a balance between cut quality and productivity.
