The Disabled Analysis Of The Diamond Saw Blade

With the development of architecture, cutting diamond saw blade havebroad market prospect. In this paper, the relationship between cutting force andtechnics parameters are researched. Simulate real work conditions of circularsaw blade through the FEA method. Implement thermal analysis, non-linearbuckling analysis and Thermal-mechanical coupling analysis using ANSYSsoftware for saw blades. Find the main factor for failure, and optimized designfor the structure of saw blades.1. The main effect of cutting force is the material chip mean thickness. Asthe K₁ or K₂ increased, more material must be removed, and in turn the chipthickness and cutting force should also increase. The rational technicsparameters should obtain the optimal processing technology and long sawservice life.2. The cutting force analysis model for diamond saw blades was established.And the effects of slope of slot, radius of slot base circle, angle between the leftslot side and the direction of the slot, angle between the right slot side and thedirection of the slot were discussed. Improve slot shape has been suggested tominimize the stress concentration and thereby increase the saw blade stiffness.3. Under the thermal and high-speed rotary centrifugal stress, saw shouldact buckling. Implement eigenvalue/nonlinear buckling analysis and additionalthermal stresses nonlinear buckling analysis using ANSYS software for sawblades. The critical buckling load is obtained through there analysis.The researches illuminate that the reasonable technics parameters and the structural parameters of slot is an important method for improving saw cuttingperformance and avoiding buckling for saw blade. It can guide a new sawdesigns in theory and practice.
