Round 1
Reviewer 1 Report
The manuscript "Research on high speed vibration and structure optimization of multi-wire sawing machine" submitted for publication on "Applied Sciences" has been reviewed. This is not a research article. It is not clear what is new in relation to the state of the art. Which is the main goal? It appears more like a technical report than a research article. Discussion is not deep enough and not clear respect to the results. In my opinion the manuscript is not suitable for publication on Applied Sciences and it should be rejected.
English language in some cases is hard to understand and should be deeply revised by english native speaker.

Reviewer 2 Report
In this study, the authors delve into the structural optimization of multi-wire sawing machines through rigorous investigation.
The simulations are conducted using the finite element method.
Various schemes for optimization have been carried out within a significant parameter space.
The authors have effectively demonstrated the convergence of the approach.
The selected topic is relevant to the field and the results presented add new insights to the existing body of knowledge.
The manuscript is written to a satisfactory standard, meeting the expectations of the journal.
Consequently, I recommend the acceptance of this paper, subject to minor revisions as follows:
The text formatting requires attention due to unintentional errors.
For instance, in the Abstract, on lines 19 and 22, the words "accuracy" and "optimized" are incorrectly hyphenated as "ac-curacy" and "op-timized."
Similarly, the word "efficiency" on line 34 appears as "ef-ficiency", and "vibration" on line 85 is written as "vi-bration".
Additionally, the title of the subsection on line 280 appears as "ensitivity Screening", which likely should read "Sensitivity Screening".
These errors suggest a thorough proofread is necessary to enhance the overall presentation and readability of the manuscript.
The quality of the language meets the expected standard.

Reviewer 3 Report
This paper entitled “Research on high speed vibration and structure optimization of multi-wire sawing machine” investigated the vibration phenomenon of multi-wire saws through modeling and experiments to improve the stability of these saws. Through reading this manuscript, the following major issues were found.
1) The English writing of the paper must be improved significantly. Grammar errors are extensive which affected the understanding of this paper. It should be checked by a native English speaker or formater. Otherwise, it cannot meet the quality of the journal.
2) The paper is not proof-read. Typos are everywhere. Please check the spelling very carefully. With so many typos, the quality of this paper is quentioned.
3) Section 2 is also the results (section 2 is the modeling results), and therefore, should be in section 3 Results section. Change the title as needed.
4) As mentioned that the experimetal data differed from the modeling data significantly. This indicates over assumption in the model. Consider address this issue more clearly in the paper.
5) The discussion section is too short. Consider make results and discussion section together.
English Language must be improved significantly. The current version has extensive typos and grammar errors.

Reviewer 4 Report
This paper discussed ‘Research on high speed vibration and Structure Optimization of multi-wire sawing machine’. Some experiment results are shown.
Comments to author(s):
1. The manuscript requires proofreading.
2. The main contribution requires improvement.
3. Fig.8 shows 6 sensors, why does Fig. 9 only have 4 data?
4. The results of Fig. 10 need to be elaborated on. From Fig.10, it seems that the experimental errors are large. Is this data suitable for structural optimization?
5. There are some typos, such as
Line 95 :‘and a indicates the size’
Line 280:’ ensitivity Screening’
6. The reviewers encourage experimental validation as a major plus for this study.

2）The content has been changed, please refer to the attachment.
3）Because the picture is only a schematic diagram of the sensor installation, the specific test process is to avoid the contingency of the data, and six sensors are used in each part of the test. Six groups of test data were compared and analyzed, and the appropriate one was selected as the final result.
Measuring position of main frame
Measuring position of subframe
Measuring position of electric control cabinet
Measuring position of base Bracket
4）According to the on-site investigation of the enterprise, it is found that the on-site situation is consistent with the phenomenon produced by the calculation results. For example, when the linear speed exceeds 1200m/min, large amplitude will be generated, resulting in poor slice quality, so we believe that the calculation error is acceptable.
5）The content has been changed, please refer to the attachment.
6) In this paper, the reliability of the finite element calculation results is verified by experiments, and the multi-objective optimization of the main frame is completed through the finite element calculation results. After optimization, the linear speed is increased by 60%, and some suggestions for the optimization of the frame are provided according to the sensitivity analysis.

Round 2
Reviewer 1 Report
Unfortunately I can't see significant improvement of the manuscript in relation to the earlier version. It looks like a technical report rather than a scientific article. In my opinion the manuscript is not suitable for publication on Applied Sciences and must be rejected.
In addition to the contents of the manuscript, language should be deeply revised by a english native speaker.
Author Response
Thank you for your valuable comments on the manuscript. While we appreciate the reviewer's feedback, we respectfully disagree. We think this study makes a valuable contribution to the field because the results show that the vibration amplitude of the optimized machine running at a line speed of 2400m/min is equivalent to that of the original machine running at a line speed of 1500m/min. Under the same operating stability, the wire traveling speed has improved by 60%. This study provides guidance for the development of high-speed multi-wire sawing machines and research on vibration control strategies

Reviewer 3 Report
The comments are not taken care of carefully.
Author Response
Thank you for your valuable comments on the manuscript, we have replyed each of the comments and suggestions.
Response to the reviewer's comments：
1、The MDPI Language Editing Services have been used to polish the manuscript revised according to the reviewers’ comments.
2、Thank you for pointing this out, the typos has been corrected in the revised manuscript.
3、We think this is an excellent suggestion, this paper has merged the results of section 2 with section 3, as shown in line 162.
The title has also been changed.
4、This study investigates the vibration characteristics of a multi-wire sawing machine, and it identifies several reasons for the discrepancies between the simulated and experimental data. The difficulties in this research lie in the complex and large-scale structure of the machine, which requires a certain level of simplification in the finite element dynamic simulation to obtain results. This simplification introduces errors. Additionally, the simulation calculations are time-consuming and difficult to predict, making the research even more challenging.
During the finite element simulation process, the study attempts to ensure that the applied boundary conditions are as consistent as possible with real-world engineering conditions to obtain valid data. However, there will inevitably be some deviations from the actual operating conditions, as it is impossible to replicate real-world conditions entirely in software. This introduces another source of error.
In the vibration experimental measurements of the machine frame, multiple-point measurements are performed on each part of the frame, and the maximum value of each part’s measurement is selected as the maximum amplitude under the current operating condition. However, the measurement errors of the sensors also contribute to the discrepancies between the experimental and simulated data.
Given the unavoidable errors caused by the aforementioned factors, the finite element simulation results will inevitably have some discrepancies from the actual operating conditions. The goal is to minimize the final error. After extensive calculations, debugging, and comparisons with experimental measurements, the study determines the computational boundary conditions. The results show that the simulation and experimental findings follow the same trends, with amplitude varying consistently with line speed. The error is found to be only 11.46%, which is considered acceptable after consultation with on-site engineers.
Therefore, this study concludes that the simulation results can accurately describe the relationship between amplitude and line speed and provide valuable insights for industrial design.

2、We think this is an excellent suggestion, As shown in line 421, this paper merges the discussion and conclusion, and improves and refines the main contributions in the conclusion
3、The experiment conducted in this study involved vibration measurements of four components of the multi-wire sawing machine: the main frame, subframe, electrical cabinet, and base. In order to avoid data randomness, six sensors were used to measure each part of the machine. The collected data was processed, and the maximum amplitude data for each part of the machine were selected for further analysis.
Figure 9 (formerly Figure 8) has been replaced with a specific layout diagram of the sensor positions at the experimental site. The original Figure 8 was only an illustration of the sensor positions.

This study verified the effectiveness of simulation calculations through vibration measurement experiments and performed multi-objective structural optimization of the entire machine structure based on the results. To validate the effectiveness of the structural optimization, finite element dynamic simulations were conducted on the optimized machine model.
The boundary conditions applied to the optimized model were consistent with the original model. The vibration characteristics of the machine were calculated under different line speeds, and the results were compared with the simulation data before optimization to evaluate the optimization effect of the model.
The results show that the vibration amplitude of the optimized machine running at a line speed of 2400m/min is equivalent to that of the original machine running at a line speed of 1500m/min. Under the same operating stability, the wire traveling speed has improved by 60%. This study provides guidance for the development of high-speed multi-wire sawing machines and research on vibration control strategies
5、Thank you for pointing this out, The Typos has been corrected in the revised manuscript.
6、This study conducted experimental measurements of the vibration amplitudes of the multi-wire cutting machine at different line speeds. It was found that when the line speed exceeded 1200m/min, the amplitude growth rate of the main frame significantly increased. This finding aligns with the conclusions obtained from simulations. The experiment confirmed that the boundary conditions and computational results of the finite element simulation were reliable.
Based on the results of finite element calculations, a multi-objective optimization was performed. The optimized model was then subjected to the same boundary conditions to validate its optimization effect.

Round 3
Reviewer 1 Report
Despite being marginally improved the manuscript remains unsuitable for publication on "Applied Sciences".
In addition to the contents of the manuscript, language should be deeply revised by an english native speaker.
Author Response
I appreciate the substantial effort you've dedicated to reviewing this manuscript. While you perceive this article as resembling a technical report rather than a research-oriented paper, I respectfully disagree with your perspective. This article revolves around a research study concerning vibration issues and framework optimization of multi-wire sawing machines.
This article validates the effectiveness of simulation calculations through vibration measurement experiments and performs multi-objective structural optimization on the overall machine structure based on this validation. In order to verify the effectiveness of the structural optimization, finite element dynamic simulation calculations were conducted on the optimized full-machine model after the optimization process. The applied boundary conditions remained consistent with the original model. The vibration characteristics of the entire machine were computed under different linear velocities and compared with the simulation data prior to optimization. This comparison was performed to evaluate the optimization effect of the post-optimized model. The results indicate that, after optimization, the amplitude of the machine's vibration at a linear velocity of 2400 m/min is equivalent to that of the original machine running at a linear velocity of 1500 m/min. Under the same operational stability, the cutting speed has been increased by 60%. This study provides guidance for the development of high-speed multi-wire sawing machines and vibration control strategies.
Furthermore, you mentioned that this article requires significant language improvement. However, the manuscript has already undergone language polishing by MDPI's author services, and I have also had a colleague who is a native English speaker review it. I believe your perspective in this regard is not accurate. Lastly, I would like to express my gratitude for your review of this article. I intend no offense and am merely sharing my viewpoint on the paper
