Study and Optimization Defect Layer in Powder Mixed Electrical Discharge Machining of Titanium Alloy

Round 1

Reviewer 1 Report

In this article, the authors present a powder-mixed electrical discharge machining of titanium alloys. They added graphite powder as dielectric to reduce the defect layer using Taguchi approach. The structure of the work is well prepared. It has a scientific quality. I think the quality of the work can be increased by some of the comments below.

1. In the abstract, the authors should indicate the achieved thickness of the defect layer at optimal parameters.

2. In the introductory part, the last paragraph, you should state the aim of the paper and especially the contribution.

3. Page 5, line 172, check the number of figures. I think we need figures 1 and 2.

4. Page 8, line 279, substitute the abbreviation DDS.

5. In some parts of the text the term "Duty Cycle" is used, in others it is not. It is necessary to agree in the text. For example, line 295.

6. In the discussion section, authors should state that the minimum thickness of the defect layer is reached at a concentration of 12 g/l. And make a comment on it.
