Special Issue Information

Dear Colleagues,

Micro machining comprises a variety of advanced manufacturing technologies that have developed over the last few decades into flexible, fast, and reliable processes for generating micro-scale parts or features, which can be found in aerospace, mechatronics, biomedicine, and optics. As a promising and rapidly growing technique, new processes, tools, and equipment are continuously proposed, and new structures are created and applied. The reliable application of micro machining requires an in-depth understanding of material removal mechanisms, credible characterization of created features, and advanced equipment and control methods.

In this Special Issue of JMMP, we look for recent findings on micro-machining technologies, including their application and associated research fields. Papers will be considered to show significant advancement according to progress and quality of micro machining processes, modeling and simulation, material aspects, and associated metrology concerning surface characterization.

We are interested in contributions that focus on topics such as:

  • Micro machining techniques, including micro cutting, EDM, laser machining, SEM in situ machining, Multi-energy field composite machining, etc.
  • New process, tool, or equipment for micro machining;
  • Micro machined structures and their application;
  • Micro-scale modeling and simulation;
  • Characterization of micro-machined structures;
  • Process monitoring and control.

The current study focuses on axial ultrasonic vibration-assisted micro-milling as an advanced technique to improve the machining performance of Ti6Al4V, a material whose difficult-to-cut properties present a significant barrier to manufacturing the high-quality micro-components essential for aerospace and biomedical applications. A full factorial design was employed to evaluate the influence of feed-per-tooth (fz), axial depth-of-cut (ap), and ultrasonic vibration on cutting forces, surface roughness, burr formation, and tool wear. Experimental results demonstrate that ultrasonic assistance significantly reduces cutting forces by 20.09% and tool wear by promoting periodic tool–workpiece separation and improving chip evacuation. However, it increases surface roughness due to the formation of uniform micro-dimples, which may enhance tribological properties. Burr dimensions were primarily governed by feed-per-tooth, with higher feeds minimizing burr size. The study provides actionable insights into optimizing machining parameters for cutting Ti6Al4V, highlighting the trade-offs between force reduction, surface texture, and burr control. These findings contribute to advancing ultrasonic-assisted micro-milling for industrial applications, namely aerospace and biomedical applications requiring high precision and extended tool life.
