Structural Analysis/ Non-Conforming Parts Analysis/ Manufacturing Process Analysis
Note: Due to EAR and ITAR restrictions few work examples from this position can be shared in a portfolio. Those present have been modified as to have no technical data.
A collet tool was modeled to determine the stresses on the given tool design based on engineering drawings. Images of Work have been Altered to Comply with ITAR and EAR Restrictions -No Technical Data
Supports are added to the collet to simulate the forces that it would see under operation. Images of Work have been Altered to Comply with ITAR and EAR Restrictions -No Technical Data
The stresses in the collet are determined. It was determined that this design would fail before use as the collet would not be able to handle the forces of being put in the case. A report was written and sent to the design engineer for redesign. Images of Work have been Altered to Comply with ITAR and EAR Restrictions -No Technical Data

Tooling Structural Analysis
The Task:
-
Evaluate a tool design to determine stresses incurred by the loads of normal use of the tool.
​
Tools Used:
-
NX Unigraphics
-
Ansys Workbench
-
GD&T
-
Microsoft PowerPoint
-
Microsoft Word
​
Engines Worked On:
-
F135
​
The Process:
-
Use part drawing and NX Unigraphics models to determine loads and geometries of tool.
-
Chunk and mesh the tool in ANSYS Workbench to do structural analysis.
-
Complete hand calculations to substantiate the part’s components.
-
Apply contacts, loads, and supports to the tool to simulate the use of the tool.
-
Make Von Misses and deformation plots.
-
Write up substantiation of tools and give recommendations on improvement of tool design.
-
Determine if tool meets required safety factors.
-
Write technical reports outlining findings and engineering recommendations.
​
​
Design Analysis of Non-Conforming Parts
​
The Task:
-
Evaluating the form fit and function of parts that were damaged or manufactured incorrectly.
-
Write an engineering recommendation to keep, repair, or scrap the part.
​
Tools Used:
-
NX Unigraphics
-
ANSYS
-
GD&T
-
Microsoft PowerPoint
-
Microsoft Word
​
Engines Worked On:
-
F119, PW1000G, PW1500G, PW1100G
​
The Process:
-
Identified location of non-conformance through images of damaged parts and through written documentation from the customer.
-
Identified the location of the damage on the part using part drawings.
-
Determined whether the damage was within tolerance.
-
Identified prior history of damage to previous parts seen to substantiate damaged parts.
-
Did tolerance stacks to determine the fit of non-conforming parts.
-
Worked with engineers in aerothermal and structural applications to analyze the non-conformance.
-
Wrote engineering dispositions in technical language to either accept, rework, or scrap non-conforming parts.
​
​
Machinability Analysis
​
The Process:
-
Evaluate the process for manufacturing parts based on part drawings.
-
Interpret specifications to determine the required processes including heat treatments, forging techniques, shot peening, ect.
-
Determine types of machines needed to manufacture parts, specific types of lathes, cutter types, collets, ect.
-
Use NX to visually model manufacturing processes.
-
Use cost evaluation software to determine cost of manufacturing parts.
