Based on the multivariable quality loss function, the quality loss of products with multi-correlated characteristics was formulated as a function of its related process tolerances. A comprehensive model to concurrently allocate optimal design and process tolerances based on minimizing the combination of quality loss and manufacturing cost was established, the purpose of the model is to balance manufacturing cost and quality loss so that concurrent allocation of optimal design and process tolerances for products with correlated characteristics was realized, and product quality improvement and cost reduction were achieved. An example of a bevel gear assembly involving concurrent optimal allocation of design and process tolerances was given to demonstrate the effectiveness of the proposed method.
