Energy consumption modeling and parameter optimization of tower combined diamond circular saw blade

Abstract

To precisely forecast the power of a tower combined diamond circular saw blade during material sawing, a model for sawing power was established using the average thickness of an undeformed chip from a single grinding grain of an individual saw blade within the combination saw as a medium. This model was then refined to enhance accuracy. A fast and accurate prediction model, requiring only a small number of samples, was developed. Sawing power was measured through various parameter combinations via sawing experiments, and model coefficients were obtained by fitting the data using multivariate linear regression techniques. An optimization model was subsequently established, with sawing parameters as optimization variables. The objectives of this model were to minimize sawing specific energy and reduce sawing time. An optimized particle swarm algorithm was adopted to solve the model. The experimental results reveal that the parameter model can comprehensively elucidate the influence of various sawing parameters on sawing power, with the model accurately forecasting the sawing power under different saw blade combinations. The improved particle swarm algorithm demonstrates strong optimization performance, with optimized parameters contributing to significant reductions in sawing power.
