Influence of cutting conditions on kickback speed in milling wood materials
An analysis of accidents has shown that many fatal and serious accidents during woodworking result from kickback. This study assessed the influence of cutting conditions on hazards associated with kickback in milling wood materials. The research concerned the severity of hazards but not the probability of kickback. The speed of kickback was accepted as the quantitative measure of these hazards. An original method of kickback experimental testing on unique research test stand was applied. The speed of kickback was measured in different cutting conditions. The experiment involved controlled changes in cutting conditions, such as the type of cutting tool, cutting speed, machined material, and tool wear. Statistical analysis of the results verified some common opinions and ideas on the impact of basic cutting conditions on the hazards resulting from kickback during milling of wood materials. In some cases, the results of empirical testing did not confirm the commonplace opinions.
