MEC 1012 - Design Communication II
Assignment 1- Review of MEC 1011
must meet the conditions and objectives of this assignment in order to earn a
passing grade in the course.
This Assignment is an abbreviated version of the MEC
1011 Final Project.
Your assembly (or sub-assembly) must include 3
or 4 custom parts and be held together by a set of at least two standard
fasteners. Your fasteners may be identical (i.e. two of the same screw).
You may start with an existing design whose
drawings are not available to you, or you may design from your imagination and
Your models must demonstrate the appropriate
use of: Revolve, 3D
Fillet, Shell, Rib, Thread, 3D Pattern, 3D Mirror, and Projected Geometry.
Your documentation must adhere to the standards
of completeness and quality outlined in Priorities 1 and 2 of the MEC
1011 Final Project
Your tolerances must be consistent with your
design guide’s stated process capabilities and minimum clearances (i.e.
your parts must fit together and be ‘manufacturable’).
Zero draft is allowed. Also, the nature of some fit must depend on feature size
and location (i.e. a pair of screws holding two parts together like
assignment 10 from MEC 1011). This does not require geometric tolerances, but
consider using them anyway.
Produce a concept sketch of an assembly or
sub-assembly that meets the conditions above.
Produce a complete set of working drawings
based on your concept using Autodesk Inventor. Set up and use an Inventor
project file in V:\MEC\1012\Spring_05\Assignment1\TXA\username. Use A-size
portrait or B-size landscape sheets.
Develop a design guide, using Word, to compile
the rules of the design, ranging from aesthetics (ex. brushed stainless parts
fastened with black socket-head cap screws) to manufacturing process plans and
capabilities (capabilities include minimum reasonable tolerances and
what geometric restrictions apply, like draft for casting). Your guide
should also specify minimum clearances between mating parts. Consider
table and outline structures for your design guide (see example).
Save your design guide (.doc or .htm) in your V:
Exchange feedback with a peer. After making all
necessary changes based on feedback, you must indicate who checked the drawings
using the 'Checked by' iproperty.
Turn in a paper package (stapled top left)
Set of working drawings (A-size portrait or
B-Size landscape printed 1:1 with drawing scale of your choice. Fold B-size
pages accordion style).
