In the veneer cutting process, compression and restraint caused by a pressure bar play an important role, but few studies have dealt with their effects upon the cutting phenomena. Therefore, the main purpose of the study reported here was to obtain quantitative information on these aspects. Roller bars with various diameter (D) and of various rolling types were prepared to vary the depth (γ_1) of restraint by interface between the face of the roller bar and the knife rake-face, the action area of restraint, and the degree of friction between the face of the roller bar and the tight side of the veneer. White seraya veneer, 10mm thick, was cut with five rolling types of the roller bars, and the knife check of the loose side, the crack of the tight side and the curvature of the veneer were measured. Based on these measurements, their variations under various experimental conditions were clarified, and characteristics of the veneer cutting with a roller bar were discussed.
