Optimizing low-frequency vibration-assisted bone drilling minimizes force, temperature, and roughness. This multi-objective approach enhances surgical outcomes and reduces bone tissue trauma.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Surgical Technology

Background:

  • Bone drilling parameters significantly impact bone tissue trauma and surgical success.
  • Coordinating multiple conflicting indicators like force, temperature, and roughness is challenging with single-objective optimization.

Purpose of the Study:

  • To conduct multi-objective parameter optimization for low-frequency vibration-assisted bone drilling.
  • To minimize drilling force, temperature, and surface roughness simultaneously.

Main Methods:

  • Central Composite Design (CCD) for establishing regression models.
  • Analysis of variance and residual analysis for model validation.
  • Non-dominated Sorting Genetic Algorithm II (NSGA-II) for Pareto optimal solutions.

Published on: September 13, 2022

Main Results:

  • Optimal parameters identified: spindle speed 2000 rpm, feed rate 0.18 mm/s, voltage 200 V, frequency 170 Hz.
  • Predicted values: 35 N (force), 61°C (temperature), 1.05 μm (roughness).
  • Validation experiments showed prediction errors within 15%.

Conclusions:

  • The proposed multi-objective optimization method reliably reduces bone drilling damage.
  • Combining optimized parameters with pre-cooling further decreased drilling temperature to 50.3°C.
  • This method offers significant clinical value for low-damage, high-quality bone drilling surgery.
