A Novel Performance Prediction Model for the Machining Process Based on the Interval Type-2 Fuzzy Neural Network

Abstract EN

The prediction model is the most important part of the virtual metrology system.

Predicting the performance of the machining process has been widely applied in manufacturing, which can reduce costs and improve efficiency compared with the manual operation.

In this paper, a novel performance prediction model for the machining process is proposed based on the interval type-2 fuzzy neural network.

The interval type-2 fuzzy logic system with a complete rule base, type-reduction, and defuzzified output is simplified by the BMM method to meet the requirements of the prediction.

The proposed prediction model is trained using a gradient-based optimization algorithm.

To evaluate the performance of the proposed approach, it is applied to wire electrical discharge turning process for predicting material removal rate and surface roughness with a published dataset.

The results show that the proposed method is an effective scheme in the studied cases.
