Reviewer 4 Report

In this paper, the correlation model of the instantaneous cutting energy efficiency with milling cutter and its cutter teeth was established. Using the cutting energy efficiency and the specific cutting energy and its distribution on the cutting edge of cutter tooth, the dynamic relationship between effective cutting energy transfer and conversion of milling cutter was characterized. The authors cover a very interesting topic. Following comments/suggestion must be given due attention.

1)     It is suggested to provide a brief explanation of some terminologies introduced in the introduction section such as, intermittent cutting process, instantaneous cutting energy consumption, distributive variation, cutting tooth error, distribution function, and tangential force energy consumption.

2)     It is suggested to rewrite the statements made in the early part of introduction section with more clarity, e.g,

(i)              Line 29-31: "In the high-efficiency and intermittent cutting process of a milling cutter, due to the changing cutting load, the input energy and the output energy of the milling cutter is an unstable".

(ii)            Line 36-38: "The instantaneous multi-tooth cutting model of milling cutter determines that the instantaneous energy efficiency of milling cutter is composed of the instantaneous energy efficiency of each cutter tooth involved in cutting".

(iii)          Line 42-44: "Meanwhile, the instantaneous cutting behavior of the cutter teeth is in an unstable in the workpiece coordinate system under milling vibration and cutter tooth error".

3)     It is recommended to avoid the compounding of references.

4)     Literature review lacks critical discussion of the previous studies. It is recommended to extend the literature review by adding more recent studies.

5)     One of the known causes of nonlinearity in milling process is the tool runout and cycloid path of cutting edge. It is suggested to provide some discussion on the effect of cutting parameters on the energy consumption in the nonlinear process.

6)     It is recommended to add the motivation of the current study in terms of the shortcoming in the literature on the instantaneous cutting energy efficiency and specific cutting energy of cutter tooth.

7)     Organization of the manuscript should be added at the end of introduction section.

8)     Fig. 1 presenting the instantaneous cutting posture and energy of milling cutter under vibration seems crowded. It would be good for the sake of readers understanding, if Fig. 1 is modified by removing the redundant information. Same is true for Figs. 3 & 4.

9)     Is the proposed model can be implemented on all the milling operations or it is valid only for a specific milling operation?

10) How does the instantaneous shear energy, equation (18) is derived?

11) It is suggested to add the accuracy and validity of the parameters measured in the conducted experiment.

12) Quality of Figs. 6-11 are very poor. Axis labels, legends and text is not clear.

13) In my opinion, number of figures (31) presented in the manuscript is high for a standard journal article.  

14) It is suggested to add the reasons for selecting the simulation parameters to the manuscript. 

15) Assumptions used in the modeling needs to be clearly defined.

16) The limitations of the research and future developments need to be better explained in the conclusions.
