Surface Quality and Geometric Accuracy Control of Fuel Nozzle Single-Pass Honing

Abstract

Surface quality and geometric accuracy are important evaluation indexes for machining quality of parts. In order to realize the quality control of nozzle honing, it is necessary to clarify the influence of honing parameters on surface roughness, dimension accuracy and shape accuracy. Cutting force is an important process parameter, which has an important influence on machining quality. The research on the influence of honing parameters on cutting force contributes to explain the honing process and the influence of honing parameters on machining quality. Therefore, the cutting force during honing was analyzed and modeled, and the influence of honing parameters on cutting force was clarified, and then the influence law of honing parameters on surface roughness, bore diameter and shape accuracy was explored. Finally, according to the processing requirements of fuel nozzles, the honing process optimization was carried out and the optimal processing parameters were obtained.
