This paper is the second in a series that describes the progress of work on a PhD thesis. The present paper focuses specifically on a waste wood chipping machine, its construction and working principle. The main problems are discussed as well as up-to-date technical improvements and optimization. It also describes the essential, characteristic parameters of the cutting regimes in the cheeping process. As a result, it has been established that the distance between the knives and counter knives is a cyclic variable, caused by cutting force-induced counter knife vibrations. A brief insight is given into the influence of vibration on cutting regimes. In the conclusion, further steps towards minimizing counter knife vibration are offered. Subsequent research is described, aimed at developing comprehensive diagnostic methods for wood cheeping machines.
