  3. IES - 2005 Assertion (A): Carbide tips are generally given negative rake angle. Reason (R): Carbide tips are made from very hard materials (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


  4. IES Statement () The ceramic tools used in machining of material have highly brittle tool tips. Statement (il) : Ceramic tools can be used on hard-to machine work material. (a) Both statement (I) and (II) are individually true and statement (II) is the correct explanation of statement (I) (b) Both statement (l) and statement(lI) are individually true but statement(lI) 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 (Il) is true


  5. IES - 2002 Assertion (A): Negative rake is usually provided on carbide tipped tools. Reason (R): Carbide tools are weaker in compression. (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


  6. IES 2011 Which one of the following statement is NOT correct with reference to the purposes and effects of rake angle of a cutting tool? (a) To guide the chip flow direction (b) To reduce the friction between the tool flanks and the machined surface (c) To add keenness or sharpness to the cutting edges. (d) To provide better thermal efficiency.


  7. GATE - 2008 (PI) Brittle materials are machined with tools having zero or negative rake angle because it (a) results in lower cutting force (b) improves surface finish (c) provides adequate strength to cutting tool (d) results in more accurate dimensions


  8. ES-2006 Which of the following is a single point cutting tool? (a) Hacksaw blade (b) Milling cutter (c) Grinding wheel (d) Parting tool


  9. IES 2012 Statement (I): Negative rake angles are preferred on rigid set- ups for interrupted cutting and difficult-to machine materials. Statement (II):Negative rake angle directs the chips on to the machined surface (a) Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I) (b) Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (c) Statement (I) is true but Statement (II) is false (d) Statement (I) is false but Statement (II) is true


  10. IES-2003 The angle of inclination of the rake face with respect to the tool base measured irn a plane perpendicular to the base and parallel to the width of the tool is called (a) Back rake angle (b) Side rake angle (c) Side cutting edge angle (d) End cutting edge angle
