A bandsaw (also written band saw) is a saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials to cut curves, even in thick lumber, such as in creating cabriole legs, to rip lumber and to crosscut short pieces. In this work the velocity and acceleration measurements of band saw swing frame of existing conventional bandsaw is taken by vibrometer. The Fast Fourier Transform (FFT) spectrum analyzer is used to analyze signal waveforms of band saw swing frame of conventional bandsaw as well as developed bandsaw. It is observed that the conventional bandsaw frame has dangerous but still permissible vibrations. So it is required to reduce these vibrations. From the graphs generated by FFT analyzer it is clear that the resonance level of conventional bandsaw frame is less than the new developed bandsaw swing frame.
