Remodeled bandsaw and circular saw to control washboarding during sawing:The purpose of our study is to control the rugged sawn surface like washboard during bandsawing and cicrularsawing.The cause of generation of the rugged sawn surface had been the self-excited vibration of bandsaw. The self-excited vibration occurred when the thooth passing frequencieswere slightly higher than the natural frequencies of bandsaw. By the unequally arrange of the pitch of saw teeth, it seemed to suppress the self-excited vibration control. A optimum arrange of set teeth that perfectly controlled the rugged sawn surface was random and wide level.
