A method for the design of diamond circular saw blade and the formulation of sawing process parameters

Abstract

The invention relates to a diamond circular saw web design and sawing process parameter setting method. The method includes: a model experiment is used to verify the reliability of a modal simulation analysis method; different types of diamond circular saw webs are selected, and the diameters and thicknesses of the diamond circular saw webs are used as the independent variables to perform constraint modal analysis to obtain the function relationship between the first 6 order of resonance frequency of the diamond circular saw webs and the diameters and thicknesses of the diamond circular saw webs; determining the diameters, linear cutting speed and machining rotation speed of the diamond circular saw webs and the relationship between each order of resonance frequency and the diameters and thicknesses of the diamond circular saw webs according to the size and hardness of to-be-machined materials, acquiring the relationship between excitation frequency generated during machining and the rotation speed and tooth number of the diamond circular saw webs, and setting the appropriate thicknesses and tooth number of the diamond circular saw webs to build a diamond circular saw web design and sawing process parameter constraint model under the condition that the situation that resonance and working rotation speed is smaller than critical rotation speed is avoided. The method is high in universality and applicable to the design and sawing process parameter optimization of various diamond circular saw webs.

Description

technical field [0001] The invention belongs to the technical field of engineering, and in particular relates to a diamond circular saw blade design and a method for formulating sawing process parameters. Background technique [0002] Diamond circular saw blades have been widely used in the processing of materials such as stone, glass, ceramics, crystals, and gemstones, as well as in the construction of houses, roads, and bridges. The diamond circular saw blade is a circular thin plate structure, its lateral stiffness is small, and it is prone to bending deformation. Modal analysis is to study the natural vibration characteristics of mechanical structures, and the modal frequencies of each order of the structure correspond to its natural frequencies of each order (ie, resonance frequency). According to the critical speed theory, the working speed of the circular saw blade must be much lower than its critical speed to ensure the stability of its rotation state, and the criti...

Problems solved by technology

And if the external excitation frequency is close to or equal to the natural frequencies of each order of the circular saw blade, it will cause the circular saw blade to resonate, resulting in deflection of the saw kerf, wear of the saw blade, reduced surface processing quality, cracking of stone raw materials, and even diamond circular saw blades. chip damage

At present, the design of circular saw blades and the formulation of sawing process parameters are mostly based on empirical design, and relevant theoretical research has not been transformed into practical basis and guiding methods.
