Round 1

Reviewer 1 Report

Authors present an interesting insight in machine tools vibration. The paper is well structured, Finite Element Model is correctly explanined, experiments are well conducted and conclusions are supported by results.
Nevertheless, I feel authors should include more relevant references, in this field it is possible find recent references which will improved the work quality. See under minor changes.

Reviewer 2 Report

Although the interface stiffness via estimation and adjustment method but I don't see any practical significance for the same. The author must clearly underline the why work is being carried out and where it is important for machining process.

Reviewer 3 Report

*English needs to be improved significantly, as many sentences sound confusing and it is difficult to understand what they are about. For example: 

After verification with experimental data, the error of the estimation method of all-natural frequency is less than 3% and contact stiffness is less than 5%.  

sound like contact stiffness is less than 5%, instead of the estimation error

 

In section 4.5, there is mention of 1st to 12th modes, but the tables only show 6 modes

 

Also, there are only 7 references in the paper, all appearing in the introduction. I suggest adding more references, especially in the theoretical section, and maybe also when describing the methodology used for experimental/numerical work

 

From the beginning of the paper, footing is mentioned as the relevant influential factor for the calculations, but it is only compared to other contact interface stiffness cases halfway through the paper. Shouldn't it be the other way around, i.e., the most significant contributing contact interface stiffness should be determined before it being selected?

Reviewer 4 Report

This paper presents a practical approach to establish the estimation and adjustment methods of the interface stiffness for the machine-tool through the finite element analysis (FEA).

The study seems to be consistent; the main goals of the study are clearly highlighted. However, I have the following comments:

1-     The research background and existing literature are too limited.

2-     It would be great if the drawbacks and gaps of literature are clear and, particularly, how the proposed approach aims at filling these gaps.
