Additional research based on previous article, titled „ Correlation between the cutters wear and chip thickness in milling of MDF". Report shows results of research on influence of tool wear and chip thickness on various parameters characterizing milling of medium density fiberboard. Cutting force, feed force, machined surface temperature and power consumption of cutting and feed mechanisms are presented, is presented in the paper. The correlation between chip thickness (feed rate), steel tool wear and force, power and temperature parameters cutting length is calculated and described.
