Hydraulic Cylinder Boring Quality Range Analysis Based on Orthogonal Test

Abstract

The reliability of the hydraulic cylinder influences the safe working of the mechanical equipment. So, there are very high technical requirements and machining precision for the hydraulic cylinder. The manufacture deviation of the bore diameter will appear in the machining process. It will influence the working performance of the hydraulic cylinder. The paper determines the influence factors of the hydraulic cylinder machining quality and the different factor level, conducts the orthogonal tests of the boring quality of the hydraulic cylinder. According to the range analysis of all test data, the following conclusions can be drawn. The best match of all kinds of factors is A3B2C2D3. The influence of cutting speed on boring the quality of the hydraulic cylinder is the largest. The influences of cutting tool type, the number of boring tool used in boring, and the feed quantity on the quality of boring are minimum.

“…The intuitive analysis (range analysis) in the orthogonal tests [40] is a simple method to estimate the significance of the factors. A greater range ( s ) implies that the corresponding factor is more significant.…”
