No it should be considered as a machine tool parameter.

If quantity of interest is cutting speed i.e the tangential speed at the interface between the tool and the workpiece. The calculation of cutting speed has a dependency on tool radius, in circumstances where a rotating tool is used (milling, drilling etc). In the case of a static tool i.e. turning, cutting speed will be a function of the diameter of the workpiece.

Depth of cut will also have axial and radial components.

Thank-you A.Levers sir for suggestions

Actually i submitted resarch paper in journal there i got reviewer comment that machining, the process parameters are cutting speed, feed and depth of cut. Angular speed of the spindle (in rpm or any other unit) is not a process parameter. The manuscript is to be rewritten.

So i am confused

I'm a little confused too now.

If the reviewer of your paper has made the comment that spindle speed is not a machining parameter, then I agree with your reviewer.

Spindle speed is obviously a significant parameter of cutting speed, but it is an input value into the calculation of cutting speed.

This is a very basic reference, but you may find it useful

Thankyou A. Levers sir

For your valuable reply but i am still confused.

It would be helpful if you try to explain why you believe spindle speed is a machining param (assuming that is still the source of your confusion)

Actually sir , i made manuscript calculation with consider spindle speed and find optimum solutions. Now rewritten means all optimum value changes again and regression model also ,

so what will i do for easily changes

I’m not sure I can give you any assistance without understanding the work you have done in more detail, and what you are trying to optimise.

I think the lesson you can take from the experience is that it is essential to position your work against an established body of reference material.

Good luck

From spindle speed you can find cutting speed in turning,milling,grinding ..etc.

A.lever sir actually i optimize parameter for minimum defect on specific material so i done all my calculation considered parameter spindle speed, feed rate and point angle of tool.

Saad sir thanks for suggestions

Thankyou to A.levers sir

In the case of rotating tool, you may consider spindle speed. In case of turning, steel is static, you can consider cutting speed includes diameter and rotation.

Thankyou palanikumar sir, my case is optimization of drilling process on composite. So according to your suggestions we can consider spindle speed is process parameter.

you seem to be searching for a way of justifying your assumptions, rather than using the extensive body of reference material which is both freely available and easy to find as a basis for your work. It may be that by coincidence the diameter of your tool is equal to that of the spindle, but this does not make spindle speed a cutting parameter. Your reviewer has already pointed this out to you and rejected the paper because of this assumption.

Yes A. Levers sir ,

I m rewritten manuscript by change spindle speed into cutting speed. I just share my rejection cause show it will be helpful other too.

You are right best way just rewrite according to reviewer comments.

Hi Janak

Read these two review papers:

https://www.sciencedirect.com/science/article/pii/S2238785416302617

Article Recent advances in drilling hybrid FRP/Ti composite: A state...

Thankyou Aamir sir,

both article are very specific and helpful for drilling of composite.

There is a difference between the spindle speed and and the cutting speed, the reviewer's suggestion on using cutting speed is correct and i think you should review in that line. literature and previous studies abound on the relationship between the two.. Thanks

Ok..thankyou samson sir

Hello Janak,

I want also point out that, for a first approach, spindle rotational speed is related directly with cutting speed by calculation as other colleagues said, but you should consider that is not the same at all to drill or torn at 20 min-1 or at 2000 min-1: sources of vibrations, vibration modes and harmonics goes changing along the rotating speed domain so the point on this domain should at least be specified.

Daniel

Respected Daniel sir ,

Thanks for the valuable suggestions

I recommend to use Response Surface Method (RSM) as a DOE approach for your tests. In this design you could consider your parameters (i.e. cutting speed, feed and depth of cut and spindle speed. I suggest to use design expert software or Minitab software for that.

You can see the interaction effects of your parameters on your responses.

Good Luck

Yes moradi sir , thanks for the your valuable suggestion.

Actually, in DOE (Design Of Experiment) approach you can use your elective laser parameters.

Regards

Mojtaba Moghadam Sir, thanks for the response.
