very nice presented actually each sides should have very key points rather than lot stuff that destruct attention especially looking at slide compress the stuff as much as possible and explain maximum that made easy while perceiving information
  1. manufacturing and production

  3. IES - 2005 Consider the following statements: 1. Forging reduces the grain size of the metal, which results in a decrease in strength and toughness. 2. Forged components can be provided with thin sections, without reducing the strength. Which of the statements given above is/are correct? (a) Only 1 (b) Only 2 (c) Both 1 and 2(d) Neither 1 nor 2


  4. IES 2012 Statement (I It is difficult to maintain close tolerance in normal forging operation. Statement (Il): Forging is workable for simple shapes and has limitation for parts having undercuts. (a) Both Statement (I) and Statement (lI) are individually true and Statement (II) is the correct explanation of Statement (I) (b) Both Statement (I) and Statement (Il) are individually true but Statement (II) is not the correct explanation of Statement (I) (c) Statement (I) is true but Statement (II) is false (d) Statement (I) is false but Statement (II) is true

  7. IES - 2006 Assertion (A): Forging dies are provided with taper or draft angles on vertical surfaces. Reason (R): It facilitates complete filling of die cavity and favourable grain flow. (a) Both A and R are individually true and R is the correct explanation of A (b) Both A and R are individually true but R is not the correct explanation of A (c) A is true but R is false (d) A is false but R is true


  8. IES 2014 In hot die forging, thin layer of material all around the forging is (a)Gutter space, which nlls up hot gases (b)Flash, the width of it is an indicator of the pressure developed in the cavity forging material (c) Coining, which indicates the quality of the (d)Cavity, which is filled with hot impurities in the


  9. IAS - 2002 Consider the following statements related to forging: 1. Flash is excess material added to stock which flows around parting line. 2. Flash helps in filling of thin ribs and bosses in upper die 3. Amount of flash depends upon forging force. Which of the above statements are correct? (a) 1, 2 and 3 (b) 1 and 2 (c) 1 and 3(d) 2 and 3


  10. lES - 1993, GATE-1994(PI) Which one of the following manufacturing processes requires the provision of 'gutters'? (a) Closed die forging (b) Centrifugal casting (c) Investment casting (d) Impact extrusion
