Mathematical model of hardening the disk-shaped saw teeth with laser beams

Abstract

Abstract The mathematical model of hardening the disk-shaped saw teeth with laser beams has been developed, and in terms of results of theoretical research based on this mathematical model, it has shown that it is advisable to use laser heat treatment technology for disc saws. At the same time, elements with a larger mass are less likely to collide with an increase in mass during operation. If the mass of the element increases by two times, the probability of collision decreases by three times. In general, it has been known that thermal treatment of the material with laser beams reduces the probability of damage to the saw teeth by 1.33 times, which in turn leads to an increase in the service life of saws. Graph of the dependence of changes in microhardness when load resistance is increased by changing the specific parameters by sharpening disc saw materials using laser beams has been developed. The 3D image shows the load resistance of the saw material, the mass of the element acting on it and the connection of its impact surface. Surfaces exposed to strong impact are four times smaller than the standard material with increased material strength, i.e. resistance to hard elements is increased by four times.
