New capability indices for measuring the performance of a multidimensional machining process
作者：
Highlights：
• We propose three novel capability indices for multidimensional machining processes.
• Consider the variances of machining results on different directions may not be equal.
• The statistical properties of the point estimators for the new indices are derived.
• The simulation results show that the new indices outperform the predecessors.
• Two numerical examples further demonstrate the usefulness of our proposed indices.
