CHIPPER MACHINE KNIFE MONITORING

摘要

Knife quality monitoring in chipper ma- chines is an important task as the knife quality has a significant effect on the quality of the chips. The knives are arranged into a rotational knife disk and the impacts caused by each of the knives can be measured by using sensors. When the impact caused by the first knife is known, the impacts of each knife can be determined. The measured impacts can be compared during one revolution or between multiple revolutions and the knife quality can be analyzed from the measured impacts.
