- Abstract
The transverse vibration of bandsaw blade in the sawing process is a well-known cause of material loss, bandsaw wear, and poor surface quality of workpiece. Five types of surface textures with inverted triangle structure on blade of bandsaw were developed to study their influences on the transverse vibration for sawing. These surface textures with the same total area were designed to identical size with different depths and identical depth with multiple sizes, respectively. The experiments on sawing 45# steels showed that the surface textured bandsaw could reduce the root mean square error (RMSE) of the lateral force by 38.22~48.42% in time domain. Compared with the non-textured bandsaw, the reduction occurred between 300 and 400 Hz in frequency domain. It was probably due to the different effects of dynamic pressure produced by cutting fluids in surface texture. In addition, the textures with the depth to diameter ratio δ = 0.01 showed the best result in this study.
