ME8381                 COMPUTER AIDED MACHINE DRAWING                             L T P C
                                                                                                                            0 0 4 2

OBJECTIVES:

  • To make the students understand and interpret drawings of machine components
  • To prepare assembly drawings both manually and using standard CAD packages
  • To familiarize the students with Indian Standards on drawing practices and standard components
  • To gain practical experience in handling 2D drafting and 3D modeling software systems.

UNIT I DRAWING STANDARDS & FITS AND TOLERANCES                                                                12

Code of practice for Engineering Drawing, BIS specifications – Welding symbols, riveted joints, keys, fasteners – Reference to hand book for the selection of standard components like bolts, nuts, screws, keys etc. – Limits, Fits – Tolerancing of individual dimensions – Specification of Fits – Preparation of production drawings and reading of part and assembly drawings, basic principles of geometric dimensioning & tolerancing.

UNIT II INTRODUCTION TO 2D DRAFTING                 16

  • Drawing, Editing, Dimensioning, Layering, Hatching, Block, Array, Detailing, Detailed drawing.
  • Bearings – Bush bearing, Plummer block
  • Valves – Safety and non-return valves.

UNIT III 3D GEOMETRIC MODELING AND ASSEMBLY                                                                                                                                                                                      32

Sketcher – Datum planes – Protrusion – Holes – Part modeling – Extrusion – Revolve – Sweep –
Loft – Blend – Fillet – Pattern – Chamfer – Round – Mirror – Section – Assembly

  • Couplings – Flange, Universal, Oldham’s, Muff, Gear couplings
  • Joints – Knuckle, Gib & cotter, strap, sleeve & cotter joints
  • Engine parts – Piston, connecting rod, cross-head (vertical and horizontal), stuffing box, multi-plate clutch
  • Miscellaneous machine components – Screw jack, machine vice, tail stock, chuck, vane and gear pump

                                                          TOTAL:60 PERIODS

Note: 25% of assembly drawings must be done manually and remaining 75% of assembly drawings must be done by using any CAD software. The above tasks can be performed manually and using standard commercial 2D / 3D CAD software

OUTCOMES:

Upon the completion of this course the students will be able to
CO1: Follow the drawing standards, Fits and Tolerances
CO2: Re-create part drawings, sectional views and assembly drawings as per standards
