Problems solved by technology

It is a feasible method to use genetic algorithm to automatically optimize NURBS curve grooves. However, with the increase of the complexity of curve control points and the increase of design variables, the optimization algorithm is prone to fall into local extremum prematurely and lead to premature phenomenon, and finally fails. get a satisfactory result

Abstract

The invention discloses a low-noise circular saw web and a preparation method thereof. The circular saw web comprises a substrate, wherein tooth segments are distributed at the outer edge of the substrate; a mounting hole is formed at the center of the substrate; curve slots are uniformly distributed on the circumference of the substrate between the mounting hole and the tooth segments. The low-noise circular saw web is characterized in that the curve slots uniformly distributed on the circumference of the substrate are NURBS curve slots, and the NURBS curve slots obtained by leading in a genetic algorithm optimization design improved by a simulated annealing mechanism. The preparation method comprises the following procedures; (1) selecting and preparing a substrate material; (2) preparing a transition layer between a tool bit and the substrate; (3) preparing the tool bit; (4) welding the tool bit and the substrate; (5) carrying out laser grooving on the substrate according to the NURBS curve slots employing the optimization design.

Description

technical field [0001] The invention relates to building material processing technology, in particular to a low-noise circular saw blade and a preparation method thereof. Background technique [0002] The "Sanitation Standards for Noise in Industrial Enterprises (Trial Draft)" promulgated by the Ministry of Health stipulates that the ambient noise value of workers exposed to noise for 8 hours per working day shall not exceed 90dB; the ambient noise value of 1 hour exposed to noise shall not exceed 94dB . When the diamond circular saw blade cuts stone, due to the mutual friction and impact with the stone, the substrate will vibrate violently and accompanied by strong noise. The noise value of ordinary diamond circular saw blades can reach about 110dB when cutting stone, while the radiation noise value of low-noise diamond circular saw blades can be reduced by 10-15dB compared with ordinary circular saw blades. [0003] At present, there are two main methods of preparing low...
