ME 440 Fall 2014 Project 1 |
|||
|
The
following data are taken from McMaster-Carr ( http://www.mcmaster.com/#adjustable-pliers/=tnjkcq
). Design a
standard adjustable self-gripping pliers (not necessarily identical to the
one below) with the following
specifications: ·
Overall
length: 6” ·
Maximum
jaw opening: 1¼” ·
Jaw
length: 1”. ·
Number
of positions: 6 The
major design steps are: ·
Assume
that loads are static (use the worst-case scenario). ·
Use an
appropriate human factors handbook to obtain suitable dimensions for the
wrench. ·
You
are to choose materials and dimensions such that the machine will not fail
due to any possible combinations of stresses. ·
Use
the rapid prototyping machine to create a model of your design (Half-scale). Note: You may need to disassemble a pliers to better understand its workings.
