Embodiment 1

[0046] In this embodiment, the optimal design of abrasive grain parameters on the surface of the saw blade is aimed at obtaining high processing efficiency. The workpiece is G603 granite, and the processing efficiency is 1200m 2 / s. The sawing amount given by the user gives the set sawing amount (sawing speed v s =45m / s, feed speed v w =6m / min, sawing depth a p is 10mm).

[0047] (1) Set the target abrasive grain cutting thickness distribution according to the processing results, such as figure 1 The distribution 1 is shown in 1; the given sawing amount adopts the value given by the user; the abrasive grain parameters on the surface of the saw blade are initialized, and the abrasive grain size and blade height are both normal distributions. The blade height is N(67,0.15), Δw=1.5mm, ΔX=3mm.

[0048] (2) Calculate the thickness distribution of the abrasive grains on the surface of the saw blade and the amount of sawing, and calculate the thickness distribution of the abras...

Abstract

The invention discloses an abrasive particle parameter optimal design method for a saw web with abrasive particles arranged in a parameterized mode. The abrasive particle parameter optimal design method comprises the following steps that (1) abrasive particle cutting thickness distribution is set according to a machining result, a set saw cutting parameter is given, and a saw web surface abrasiveparticle parameter is initialized; (2) the saw web surface abrasive particle parameter and the saw cutting parameter are subjected to abrasive particle cutting thickness distribution calculating, andabrasive particle cutting thickness distribution is worked out; (3) the abrasive particle cutting thickness distribution worked out in the step (2) is compared with target abrasive particle cutting thickness distribution set in the step (1), if the difference between the abrasive particle cutting thickness distribution and the target abrasive particle cutting thickness distribution is too large, the abrasive particle saw cutting parameter is adjusted, the cycle of the step (2) and the step (3) is performed again till the difference between the abrasive particle cutting thickness distribution worked out in the step (2) and the abrasive particle cutting thickness distribution set in the step (1) meets the set standard, calculating is stopped, and then, the saw web surface abrasive particle parameter is the optimal result; and (4) the saw web is manufactured based on the saw web abrasive particle parameter serving as the optimal result. By adopting the saw web to conduct machining, the expected machining purpose can be effectively achieved.

Description

technical field [0001] The invention relates to the field of sawing, in particular to an optimal design method of abrasive grain parameters of a saw blade with parametric abrasive grain arrangement. Background technique [0002] Sawing processing is the main processing method of parts cutting processing and an important part of advanced manufacturing technology. The control of the sawing process and the accurate prediction of the processing results are very important for efficient precision sawing processing technology. Sawing processing is a processing method in which many abrasive grains are respectively micro-cut under the control of a bond, and then macroscopically remove the workpiece material. In other words, sawing is the removal of material on the tool at the macroscopic level, and at the microscopic level, each abrasive grain is actually cut. Therefore, the cut thickness value of each abrasive grain has always been a key control quantity for the sawing process and...
