MF3411 Computer Aided Product Design and Assembly Laboratory Syllabus:

MF3411 Computer Aided Product Design and Assembly Laboratory Syllabus – Anna University Regulation 2021

COURSE 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
• Preparing standard drawing layout for modeled parts or assemblies with BoM.

A) DRAWING STANDARDS & FITS AND TOLERANCES

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.

B) 2D DRAFTING

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

C) GEOMETRIC MODELING AND ASSEMBLY

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.
• Design and Assembly of real time industrial products.
• 3D modeling from 2D product drawing
• Preparation of 2D drawing from 3D model for manufacturing

TOTAL : 60 PERIODS
COURSE OUTCOMES:
