Area of Science:

  • Materials Science
  • Mechanical Engineering
  • Manufacturing Technology

Background:

  • High-precision machining of micro-channels in hard and brittle materials presents significant challenges.
  • Existing methods often struggle with achieving both high efficiency and superior surface quality.
  • The need for advanced techniques to overcome these limitations is critical in microfabrication.

Purpose of the Study:

  • To introduce and validate a novel technology, template-based electrophoretically assisted micro-ultrasonic machining (TBEPAMUSM), for micro-channel fabrication.
  • To design and develop a dedicated machine tool and intelligent control system for TBEPAMUSM.
  • To evaluate the performance improvements offered by TBEPAMUSM compared to conventional methods.

Main Methods:

  • Development of a TBEPAMUSM machine tool with a C-shaped structure, incorporating a marble platform, ultrasonic vibration system, micro 3D motion platform, working fluid tank, and pressure sensor.
  • Implementation of an intelligent control system using LabVIEW, featuring modules for initialization, positioning, tool setting, machining, and real-time display.
  • Machining of micro-channels on single-crystal silicon and soda-lime glass using the developed system, with and without electrophoresis assistance.

Main Results:

  • Electrophoresis assistance significantly reduced edge chipping in micro-channels.
  • Surface roughness was improved by approximately 20% with the application of TBEPAMUSM.
  • Machining efficiency saw an increase of about 4% when using the electrophoretically assisted method.

Conclusions:

  • TBEPAMUSM is an effective technology for high-precision and high-efficiency micro-channel machining of hard and brittle materials.
  • The developed machine tool and control system successfully implement the TBEPAMUSM principle.
  • The integration of electrophoretic principles offers tangible benefits in reducing defects and enhancing productivity in microfabrication.
