• Double spring mechanism
• Small ball burnishing
• Grey-based Taguchi method
• Principle component analysis
• Grey entropy

In this study, a novel load cell embedded small ball-burnishing tool with a double spring mechanism was designed and fabricated to conduct the burnishing process on STAVAX material. The influences of process parameters, namely burnishing lubricant, burnishing force, step-over, burnishing speed, and number of passes, on the surface roughness and superficial hardness of the workpiece were investigated. The hybrid grey-based Taguchi method with the weighting coefficients estimated by principal component analysis and grey entropy was employed for experimental design and data analysis. After conducting two sets of experiments, the optimal small ball-burnishing condition on STAVAX material was determined.
