Cutting Forces and Merchant Circle Diagram

Metal Cutting process involves a number of forces in the cutting zone that makes the removal of excesss material from the workpiece possible. The Merchant Circle Diagram provides a way to relate these forces in a graphical way. Relations between these forces can be found out through analytical formulas as well.
This 3 minute video explains the basis of each force, like cutting force, feed force, thrust force, friction force and shearing forces. It also shows the associated angles like rake angle and shear plane angle, and also the friction angle as related to coefficient of friction due to rubbing between chip and tool surface.
However, the derivation of the conversion formulas have not been included in this video. Only the expression of the conversion formulas have been shown towards the end of the video.

This was the most easiest way to understand the forces acting on tool and workpiece. The visualization of forces got clear. Animation was great. Thank you. :)

[@Mech4Mechs]

Thank you very much.
Please do suggest any other topics you'd like to study this way ;)

[@SuperShooterX]

Could you do a material removal rate for the different types of cutting?
Thanks

[@ankitprasaddevrari4160]

Wow, after 3 years of college, i understood this..that also in 3 minutes only.

[@rohitbhosle6521]

That animation clearly is dope .... that animation alone cleared my doubt thanks for uploading

[@jaeybulzer4233]

Same here brother... I meant the three circles explanation along with the resultants combined into one.. was dope...
Clear about Reference plane too..💟💟
Plzzz make videos on RAC Psychometry and Heat transfer.. in ur style

[@ketanpanchal6029]

You clear all my doubts about this thank you so much..

[@akarshitgupta6750]

great work ... very helpful

wonderful job guys!!! keep it up

[@vashushukla1727]

explained it better thanks

[@dhavaldhameliya2412]

Wow nice video and clear my doute. Bro tum cnc or variable machine tool ke animation banao.👍👍👍

[@jaytejmanyala6605]

man
y dont u make more and more videos they are very easy clear and nyc to understand too with the xcellent graphics
add more vid

Thanks a lot😃

[@Mech4Mechs]

Happy to help :)
Do suggest any other topics you'd like to study this way ;)

[@zackarystewart9214]

you can go a little longer. I find myself pausing to write things down. Thanks so much

[@Mech4Mechs]

Okay. I'll keep that in mind for my next videos. Thanks a lot. :)

[@Dsp_126]

What book should we refer

[@abhishekpanjiyar8266]

SIr which software you use for these explanations

[@Mech4Mechs]

SolidWorks + MS Powerpoint

[@karthickramasubramanian4879]

praise be

[@sravansadanandan1965]

What happens to cutting force if friction angle reduces

[@banuhiwa4199]

Thank u

[@nithinrpathiwada9304]

my question is why we have to maintain those forces in equilibrium? for what reason? and btw thanks for the awesome video

[@Mech4Mechs]

We can write force equations only in static equilibrium conditions. Hence we must bring the system to equilibrium, which is in this case, a constant cutting velocity/spindle speed. If we need to create force equations in dynamic equilibrium, we must first convert them to static equilibrium using D' Alembert's Principle.

[@nithinrpathiwada9304]

thank you

[@Mech4Mechs]

Happy to help :)
Any other topic you'd like to see presented/animated like this, please do suggest.

[@amodnayak711]

Nithin R Pathiwada since velocity is constant so the forces are in equilibrium. ......velocity is kept constant to avoid Built Up Edge

[@AshutoshSinghSengar]

awesome

[@Mech4Mechs]

Thank you :)

[@sribalaji3159]

We ll support yu

[@himanshu.g345]

Nice video.. But i have a doubt .. You showed cutting force acting on tool and friction forces on chip.. To showed them in equilibrium i think so u should showed forces either on chip or tool.. Direction of forces in your mcd is wrong..

[@jagdish51]

bhai mja agya.?

[@Shivamagrawal50]

ek tarfa!

he might be out of this planet

[@Abcdefhko]

Haha , seriously he is different , or his tutor is
