3 0 0 3
AIM
To design plastic products using CAD
OBJECTIVES
To learn CAD and NC programming; FEA, CAE for plastics and rapid prototyping
UNIT I 9
Plastics Product Design : Material Selection - Properties – Mouldability - Fits and
Tolerance – Shrinkage – Warpage - Wall Thickness – Fillets - Sharp Corners - Ribs and
Bosses - Holes- Moulded Threads - Inserts and Fasteners – Integral hinge – Lettering on
Moulded Products.
Surface finish – Functional / Aesthetic aspects of part shape-Safety aspects of part
shape - Safety aspects if the part should burn - Safety aspects if the part should fail -
Use of color and design to promote safety.
UNIT II 9
Introduction to CAD – Computer Aided Drafting – Operating Systems – Wire frame,
Surface and Solid Modeling – Using Auto CAD, Unigraphics, Ideas and Pro-E – NC
Machines – NC Part Programming – Manual part programming – Computer assisted part
programming – APT Language – Manual data input – NC Programming using CAD/CAM
Computer automated part programming.
UNIT III 9
Finite element analysis - introduction, types of analysis - need for approximation Weight
residual, Ritz and Galerkin method - Variational. Procedure for finite element analysis -
stiffness matrix, solution procedure, details of finite element analysis package, model
building, post processing, simple problems in 2D&3D Analysis and applications of FEM
for plastic components.
