Advances in Ultra-Precision Machining and Measurement for High-Quality Component Production

The rapid proliferation of high-resolution 4K and 8K imaging technologies is reshaping consumer expectations in various sectors, notably smartphones and automotive industries, where there is an escalating need for compact, precise aspherical lenses and innovative optical devices for communication lighting applications. Traditional manufacturing approaches, constrained by the capabilities of standard machining tools, fail to meet the stringent requirements for sharper diamond tools and superior positioning precision. These challenges underline the critical need for advancing Ultra-Precision Machining (UPM) and Measurement Technologies capable of producing complex, high-quality molds, dies, and large-aperture lenses.

This Research Topic aims to bridge the technological gaps in UPM through rigorous academic and industrial research. Our objective is to explore and systematize cutting-edge modeling based on process analysis and to enhance the role of Measurement Technologies in UPM. Specific goals include the improvement of tooltip shape measurement, contact detection, and measurement of high aspect ratio structures in machined materials. These advancements will contribute significantly to the development of more precise and reliable machining processes for high-quality optical parts.

To delve deeper into this burgeoning field, we welcome scholarly contributions that explore a wide range of topics, including but not limited to:

• Ultra-Precision Machining processes for hard-and-brittle and advanced materials
• Development of advanced cutting and grinding tool technologies
• Investigating unconventional machining processes
• Implementing vibration-assisted UPM with fast tool servo systems
• Enhancements in precision machine technologies and components
• Advancements in process monitoring, control for UPM, and integration of Digital Twin and IoT technologies
• Innovative approaches to tool path generation
• Cutting-edge contact and non-contact measurement technologies
• On-machine, in-situ, and in-process measurement techniques
• Strategies for error assessment and compensation
• Exploration of surface integrity and associated technologies

We invite academic and industrial contributions that push the boundaries of current technology and enable the production of components with unprecedented precision and quality.
