Overview

Experimental study demonstrates improved milling efficiency and tool life in GH2132 superalloy, highlighting optimal machining parameters.

Key Points

To optimize milling process parameters for GH2132 superalloy using an improved particle swarm optimization-backpropagation neural network (IPSO-BP) to balance material removal rate and tool wear rate.
Coupled a Back Propagation Neural Network with an Improved Particle Swarm Optimization (IPSO-BP) algorithm to build a multivariate predictive model.
Used an orthogonal experimental design to compare the IPSO-BP model against standard BP neural networks and standard factory empirical baselines.
Formulated a fitness function combining material removal rate and tool wear rate to solve for optimal cutting parameters (cutting speed, feed rate, and depth of cut).
Determined optimal milling parameters: cutting speed v = 30.23 m/min, feed rate f = 0.038 mm/rev, and depth of cut a_p = 0.35 mm.
Achieved a validation error of 4.21% for the tool wear rate under the optimized parameters.
Observed superior topographical surface uniformity compared to traditional factory empirical settings.
