Next-Generation Machine Tools and Machining Technology

Dear Colleagues,

As the cornerstone of manufacturing industry, CNC machine tools have made great progress in machine tool structure, precision control, process monitoring and automation, and data communication after more than half a century of development. At present, advanced machine tools have achieved high performance in terms of accuracy, rigidity, cutting capability and long-term precision stability. Both stand-alone manufacturing and integrated manufacturing systems have achieved a high level of machining performance.

However, in the face of cutting-edge manufacturing needs such as high value-added parts, thin-walled structures and difficult-to-machine materials, the current technologies are not yet able to fully meet these requirements. The limitations are mainly reflected in weak bidirectional data interaction, insufficient reliability of intelligent monitoring systems, difficult online measurement of part quality, etc. In addition, the overall intelligence level of the manufacturing process still requires significant improvement. Meanwhile, low-carbon production and improving workers' operational safety and comfort have also become urgent needs of the industry.

To this end, this special issue will focus on cutting-edge research on next-generation machine tools and machining technologies, focusing on:

• Efficient data interaction and collaboration: Enhance sensor configuration and CNC controller performance, realize seamless bidirectional data flow within and beyond the machine tool, and support flexible and networked production.
• Intelligent monitoring and quality control across the process chain: Build a robust monitoring system to realize real-time perception and abnormal diagnosis of machine tools, tools, fixtures, parts and personnel status.
• AI and digital twins in machine development, machining: Develop predictive models with fast response and high accuracy using the most advanced AI technology, and achieve low-latency interaction and control between virtual digital machining systems and real manufacturing systems.
• Less-manned/unmanned manufacturing systems: Develop automated and adaptive machining units for small batch and high-value parts in aerospace and other fields.
• Green manufacturing and resource recycling: Covers technologies such as precise cooling, carbon emission control, waste recycling and tool reuse to promote sustainable production.
• High-performance cutting of difficult-to-machine materials: Integrating new energy fields such as laser, thermal field, and magnetic field to improve cutting efficiency and surface integrity.Advanced tool coating technology, ceramic tools, etc.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Manufacturing and Materials Processing is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
