Composite Materials Processing with the Band Saw Blade Crack Before and After the Experiment Analysis (1)

Abstract

This article takes the MJ3210 type woodworking band saw machine as the research object. Under no load, using advanced Beijing pop vibration analyzer and the Vib sys vibration signal acquisition, processing and analysis software for vibration signal acquisition and analysis, through the saw blade transverse vibration displacement, the power spectrum analysis: The saw blade transverse vibration displacement effect on the most significant factor as the spindle speed, followed by the tension of saw blade and belt tension is not significant factors. And draw the best process parameters. Adjust the saw under optimal process parameters. Use 120 mm width is 1.02 mm thick band saw blade type MJ3210 fine woodworking band saw machine, through to the saw blade crack before and after the vibration signal correlation analysis showed that the determination of lateral vibration displacement if between 4.48μm ~ 5.14μm microns, vibration main frequency between 494 Hz ~ 528Hz, and is the saw blade has had at least one more than 3 mm crack defects, need to timely change the band saw blade.
