Processing Quality Forecast and Diagnosis for Gear-Box Shell Production Line in Manufacturing System

Abstract

By analysis of time series, this paper analyzes the machining quality of the gear-box shell in manufacturing system by exponential smoothing model and the gray prediction model, and then predicts the trend of the future product quality. By mining the association rules of the machining processes of the gearbox shell and analyzing the impact on product quality in different procedures, we get the beneficial factors on improving the machining quality of the gear-box shell; At the same time, by analyzing different factors of the same procedures, we realize the diagnosis of procedures quality by diagnosing the beneficial factors on improving the product quality.
