Grinding Process Parameters Optimization and Surface Performance Analysis of Spiral Bevel Gear Based on the Orthogonal Test

Abstract:

Based on the experimental conditions of generation grinding of spiral bevel gear, the grinding orthogonal test design of L₁₆(4⁵) is made, and the results of grinding orthogonal test are obtained. On this basis, the range and variance analyses are carried out by using an integrated balance method, and the optimizing configuration of grinding process parameters of spiral bevel gear is obtained. The test regression models of three grinding evaluating indicators of spiral bevel gear, such as the grinding surface roughness R_a, metamorphic layer depth h and removal rate Z_w, are set up by using a method of multivariate nonlinear least square. The maximal absolute value of relative error between computing values and testing ones is 18.41 percent by test validation, and this shows that the regression models are more effective. Through the test optimization of grinding surface performance, the value of grinding surface roughness R_a is more less 0.1μm than one of the normal grinding process, and other comprehensive performances are better. The pre-control measures of grinding process optimization of spiral bevel gear are also put forward. These provide a basis for the improvement of grinding surface quality of spiral bevel gear.
