Quantitative evaluation of machining quality of aircraft structural parts plays an important role in improving machining quality of parts. The rate of error limit (REL) is proposed as a new evaluation index of the machining quality, which realizes quantitative evaluation of machining quality and is applied to optimization of machining quality. Aiming at the disordering of the measurement data and lack of effective analysis in actual production of engineering, a Machining Quality Evaluation and Optimization software (MQEO) is designed and developed with REL as the evaluation index. And the multi-factor analysis of variance is used to find out the main factor influencing the machining quality, and propose optimization suggestions.
