Study on Extraordinarily High-Speed Cutting Mechanics and Its Application to Dry Cutting of Aluminum Alloys with Non-Coated Carbide Tools
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis interesting paper deals with the study of cutting forces, temperatures and coefficient of friction when turning aluminum alloy workpiece in very high-speed cutting condition. These very high cutting conditions allows to the materials to be in a viscous state depending on the specific cutting energy and the specific melt beginning energy. These two factors play a role of heat softening region during machining allows the decrease of coefficient of friction between tool and workpiece.
The structure of the paper is very good and all the process is significantly explained step by step. The procedure is educational as well as scientific.
Some points need to be revised to improve the quality of the paper, with the help of the following remarks:
1) Abstract has to be rewritten. It needs to summarize the objective of the study, the methodology used and the results found very directly and clearly.
2) In section 3.2, Authors said:” Note that tool wear can be ignored in the experiments since aluminum alloy causes only small wear”. In aluminum alloys built up edge wear can occur. Authors must talk about it.
3) The quality of figure 7 must be improved. Too much text decreases the quality.
4) In figure 8 a schematic reference forces must be integrated.
5) In order to improve the reader understanding, experiments sum-up must be integrated between section 3 and subsection 3.1 in a small paragraph.
6) The main problem is: in the title, dry cutting and non-coated carbide tool are stipulated whereas wet cutting and with coated tool are used in this study. The title could simply be “Study on extraordinarily-high-speed cutting mechanics and its application on aluminum alloys”. Or refer to remark 2)
7) Conclusion should be enlarged to show how this study could be useful for other materials or for industry for example.

Reviewer 3 Report
Comments and Suggestions for AuthorsThe paper addresses the challenging problem of high friction and heat generation in cutting processes by exploring extraordinarily-high-speed cutting (EHS-cutting). This novel approach potentially reduces the need for cutting fluids and coatings, which aligns well with current trends toward more sustainable manufacturing practices.
While the paper compares dry cutting with non-coated carbide tools and wet cutting with DLC-coated tools, it lacks detailed analysis on how the EHS-cutting performance compares to other advanced cutting technologies beyond the specific tools tested.
i have some questions
dear authrs
Could the authors provide more detailed validation of the analytical model used? Specifically, how do the assumptions (e.g., 100% heat flow into the chip) hold up in real-world cutting conditions? How would the EHS-cutting performance vary with other materials, such as titanium alloys or high-strength steels? Is there a plan to test a broader range of materials? The study primarily focuses on cutting forces and temperatures. How does the tool wear in EHS-cutting conditions compare to conventional cutting methods? Are there any observable effects on tool life and performance? What are the key challenges or considerations for implementing EHS-cutting in an industrial setting? Are there specific machine or tooling requirements that need to be addressed? How does EHS-cutting compare with other advanced cutting techniques, such as high-pressure coolant systems or hybrid machining methods? A comparative analysis could provide additional insights into the relative advantages of EHS-cutting. What future research directions do the authors suggest to further explore and validate the findings of this study? Are there any planned follow-up experiments or studies?
best of luck
