The Analytical and Experimental Analysis of the Machined Surface Roughness in High-Feed Tangential Turning
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis paper is interesting and will be attractive to researchers and engineers in the field of advanced machining. Some minor points should be addressed.
1) The authors claimed Tangential turning has gained attention due to its numerous beneficial properties. However, just a few papers are reported in the open literature. What is the disadvantages of this techniques. This aspect should be introduced in the Introduction.
2） Section 3.1. Mean Roughness Depth：a theoretical value of the Artihmetical Mean Roughness can be calculated as Equation 14. Firstly, this process method is also a typical turning method. What is the difference between roughness calculation Ra and conventional turning methods? The reviewer believes that there may not be much difference, and the tool angle parameter needs to be adjusted regardless. The formulas derived in this article have certain limitations, as some parameters (such as vt.t) do not clearly indicate what physical quantities they are. And the article did not verify its correctness at the end.
3) The writing of academic papers needs to be more standardized, and there are some editing errors. such as “909.45 1/min and 199 1136.82 1/min number of revolutions” in line 199，“vc = 250 mm.” in Line 338.
4) What is ground-like surfaces? How to improve the productivity by Tangential turning.
5) Some recent research results share the same topic of “This is caused by the fact, that the theoretical values of the studied roughness parameters are not dependent on the cutting speed and depth of cut.” For instance, papers in JMPT https://doi.org/10.1016/j.jmatprotec.2024.118296，

6) Improve the writing of conclusion. It is best to list the innovative results by item, which makes it easier for readers to understand and accept.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe article is an example of a classical qualitative scientific research. The article contains sufficient analysis of previous works, theoretical part and experimental results, partially confirming the analytical analysis of arithmetic value of surface roughness. There are no remarks on the structure of the article, the references cited, and the conclusions obtained. The article is of considerable interest for the practical use of the tangential turning method and can be published after a minor correction to disclose the following points:
-In the Introduction part of the article, in addition to the advantages of tangential turning, it is desirable to indicate the disadvantages of this method of machining, since it has a number of significant limitations in its use in practice.
- Some of the conclusions of article [Sztankovics, M. ANALYSIS OF SELECTED FUNCTION-DEFINING 2D SURFACE ROUGHNESS PARAMETERS IN TANGENTIAL TURNING. Cutting & Tools in Technological Systems, 2023, Edition 98. doi: 10.20998/2078-7405.2023.98.11] contradict the conclusions of the article under review, although the experimental conditions were almost identical.
- It is obvious that the angle of inclination of the cutting edge is a more significant factor affecting surface roughness than cutting speed or depth of cut, but the author does not mention that (line 179). The principle of selecting this angle and its effect on surface roughness is not disclosed.
