    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 .

    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?

      @@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.

    • @hallo-xp2wh
      @hallo-xp2wh 3 ปีที่แล้ว

      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

    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..

    • @romitrana8631
      @romitrana8631 3 ปีที่แล้ว

      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.

    • @paidiganesh905
      @paidiganesh905 3 ปีที่แล้ว

      @@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 ?
