Sir I haven't found the theoretical portion of Milling Machine in your playlist associated with this mathematical problem. Could you please suggest me ?
Sir na na karte smjha hi dia aapne compulsory approach. You're the greatest sir. Every other teacher is busy promiting his/her "packages", you are the only teacher whose motive is to deliver knowledge only. Thank you so much sir.
Yes, sir I love Mechanical engineering now only because of you.
Sir, i have a doubt regarding this question. In this question , they have mentioned that it is side milling cutter , which actually is a type of end milling cutter(vertical milling machine) . Also it is mentioned that it is face milling, for which vertical milling machine is preferred. But in the solution u have taken it as a peripheral milling cutter(horizontal milling machine). I did the answer taking it as end milling cutter with the corresponding compulsory approach formula, and got a different answer. Sir which one should actually be taken, and why?
How can we create a slot using a vertical milling cutter?
@@kushagratiwari96 both slot milling and face milling can be done with both horizontal and vertical milling machines. It not true that slotting can be done only with horizontal milling machine, it can bo done using vertical milling machines also
@@sumaisjalaludheen5561 yes brother it can be done with both vertical and horizontal but if we use vertical milling machine width of slot will be produced same as the diameter of the cutter.
But here the diameter of cutter is 100mm and slot width is 25 mm.
Cutter is mentioned only bro.
I am also confused......can any one explain briefly?
I m the 70th person who really understands compulsory approach,thank you so much sir , many books claim ans to be 8.1 min ,but in reality it's 7.4 .
🙏🙏🙏🙏
I think we should should challenge official solution...this explaination is correct....
Thank you sir for this.... I was searching for this everywhere.... really happy to see the logic behind the solution of this question... ❤️
❤great 👍 you're speaking in English 😊
Sir I couldn't find this lecture in video course . Are these for youtube channel only?
Yessss.... Aise hi kiya h aur yhi answer aya... I was worried seeing the solution of other institutes... What a 😌 relief
Superb explanation
sir you are using peripheral cutter which is somehow wrong... in example itself it is mentioned face mill cutter which is used on vertical milling machine and the peripheral cutter is used in horizontal milling machine.
Sir what about range in some questions they have given Very close range. I have lost 2 marks just because my answer difer by 0.01.set 1.
Sir face milling me compulsory approach ka short video bna do please
Sir please solve question of set 2, in which ratio of total time per pass for S1 and S2 is asked. It is creating a lot of confusion.
*In some websites compulsory approach is D/2, or √(d(D-d). In this video it is different. What is the difference? Help*
He did √(D^2 - (D-d)^2) basically. It is the same as √d(D-d)
Solution for vibration problem.. massless rod..paper 1 in Rayleighs method
Thank u so much such
Terrific explanation
Explanation for tom( disc) question is needed sir.
like compulsory approach... wont it have a compulsory over travel???please reply
in questions approach length and overtravel are always mentioned ,what isn't mentioned is whether to consider compulsory approach or not,it depends on data!
(ex: compulsory approach in drilling need point angle,if point angle is not mentioned ,we cannot consider compulsory approach)
no need for compulsory overtravel as the relavent data is given along with approach length
Big relief.😌😌
Thank you sir🙏
Sir it's an example of slot milling. Compulsury approach is D/ 2 na?
Hello @exergic sir in official key it was given D/2 for compulsory approach. Though 7.4 lies in the range but why they took D/2. The solution should be what you solved in the video. But how they took D/2. Hope you would give reply to my message. Thank you sir..
Here side and face milling means end milling cutter, which has teeth on periphery as well as on its face, and it is not in the shape of a wheel rather a drill like shape. So D/2 should be the compulsory approach to completely remove the material. Sir has shown a peripheral milling cutter here.
@@romitrana8631 yes but in the problem they asked to slot a 25×25 on it so we have to consider peripheral mill cutter so it is not D/2 for approach. With both the methods we are getting answers in the given range but exact compulsory approach is √d(D-d) right ?
Thank you so much sir🙏
Sir you are great
Is there anything called compulsory overtravel?
Too good!
Sir why not u considered time taken for return pass
During return no machining occurs
Thankyou sir
Does this video is added on your video course??
Sir gate answer key is different for this question . Which one is correct ?
Sir it's face filling you have taken it as peripheral milling.
Face and side milling cutter hai. Face milling nhi ho rha.aisa cutter jisse face pe bhi abrasive hai and side bhi. Qs Dhyan se padho.
if this is the depth to which a concept is deconstructed to im buying the course tomorrow
All concepts in EXERGIC course are covered from basics, and covered in depth.
sir will the answer 7.2 will be in range??
Are you brother of dhruv rathe?
Sir, Official answer key is out. And answer is 1.6. Answer of mine was 7.44. Shall I challenge?
@@Yash.027 Thanks Sir
Thanks sir I have also got 7.445.
@@Yash.027 Sir, tomorrow is the last day to challenge the answer key. Please upload the video asap.
sir i have solved the question with your approacha and every coaching was giving wrong answer.
call my mp sir please. he is so bad that the whole class started hating the subject
Sir where is your class? Address plzz
We offer online classes here: www.exergic.in
Sir I wish to meet you...Please send me your address
Official answer key shows different answer sir😕
@@Yash.027 Yes sir please make a video on how to challenge the answers also and how to write in a proper way so that professors can understand what we are trying to explain.
Sir please upload some content on your telegram channel because from November nothing is uploaded in that telegram channel
Calculation is wrong.. √50-40= 30
Official answer key is showing different answer. What about it? I got this answer.
@@Yash.027 sir, when will the answer key after challenging be released?
Thank you sir ❤🎩
