Abstract: In the veneer cutting process, compression and restraint caused by the pressure bar play an important role, but few studies have dealt with their effects on the frictional coefficient on the tool rake-face. Therefore, the main purpose of the study reported here was to obtain a quantitative information on these aspects. In this study, the roller bars with various diameters (D) and of various rolling types were prepared to vary depth (r_1) of restraint by interface between face of the roller bar and the tool rake-face, action area of restraint, and degree of adhesion between face of the roller bar and tight side of veneer. Before cutting, test specimens were preheated in water at about 95℃ for 4 hours. White seraya (Parashorea sp.) veneer, 10 mm thick, was cut with five rolling types of the roller bars, and frictional (F) and normal (N) forces acting on the tool were measured. Based on these measurements, the frictional coefficient (μ) on the rake face was calculated and its variation under various experimental conditions was determined.
