Embodiment 1

[0052] In this embodiment, the optimized design of the grinding amount is carried out with the goal of obtaining a good machined surface quality. The workpiece is No. 45 steel, and the surface roughness Ra of the processing result is expected to be less than 0.4um. The user has given the parameters of the abrasive grain on the surface of the grinding wheel. The grain size, position and edge height are all normal distributions. The parameters are: grain size N(550 ,0.25), position N(0.1,0.4), the blade height is N(67,0.15). The given processing amount is the grinding speed v s =45m / s, feed speed v w =20m / min, grinding depth a p It is 10um; the trimming amount is initially estimated to be 50um

Abstract

The invention discloses a grinding wheel dressing amount optimization design method based on abrasive particle cutting thickness distribution control. The grinding wheel dressing amount optimization design method based on abrasive particle cutting thickness distribution control comprises the following steps that (1) a set grinding wheel surface abrasive particle parameter is given, the grinding parameter is given, and a target abrasive particle cut thickness distribution is set according to a machining result; (2) after virtual dressing, abrasive particle cutting thickness distribution calculation is conducted on the grinding wheel surface abrasive particle parameter and the grinding parameter, and the abrasive particle cutting thickness distribution is worked out; (3) the abrasive particle cutting thickness distribution worked out in the step (2) is compared with the target abrasive particle cutting thickness distribution set in the step (1), if the difference is excessively large, the virtual dressing amount is adjusted, then the step (2) and the step (3) are executed circularly, and calculation is not stopped until the difference between the abrasive particle cutting thickness distribution worked out in the step (3) and the abrasive particle cutting thickness distribution set in the step (1) meets a set standard. The optimized dressing amount is used for dressing the grinding wheel, the dressed grinding wheel conducts working in combination with the set grinding parameter, and the expected machining purpose can be effectively achieved.

Description

technical field [0001] The invention relates to the field of grinding, in particular to a method for optimally designing the dressing amount of a grinding wheel based on the controlled cutting thickness distribution of abrasive grains. Background technique [0002] Grinding is the main processing method for parts with high dimensional accuracy and high surface quality, and is an important part of advanced manufacturing technology. The control of the grinding process and the accurate prediction of the machining results are very important to the high-efficiency precision grinding technology. Grinding is a processing method in which many abrasive grains are controlled by a bond to achieve micro-cutting, and then macroscopically remove the workpiece material. In other words, grinding is the removal of material on the tool at the macro level, and at the micro level it is actually the cutting of each abrasive grain. Therefore, the cut thickness value of each abrasive grain has a...
