Experience

Engineer II, ATI Forged Products – Cudahy Operations, Cudahy, WI, Fall 2015 – Winter 2017

Involved in the CAD design (Creo2.0/ProeE) and FEM model simulations (Forge NxT) of tooling dies and forge processes for Boeing components

In charge of performing FEM cooling simulations (DEFORM 10.2/11.0) and cooling trials using thermocouples data for turbine disks as well as comparison analysis of both

In charge of modeling and estimating the tooling cost as well as the forging process for new and existing customers components (This involved the design of the forge shape, die design, trimmer equipment, machining time, material cost, and forge drawings)

Developed training documents that discussed and provided detailed instructions for tooling quotes, performing FEM cooling simulations and comparison analysis, as well the as design of tooling dies and forge processes for new acquired components from customers

Helped improve tooling life and quality of forge products thru FEM model simulations and die changes for various components

Developed PowerPoint presentations for customers that indicated detailed comparison and suggestions for forging improvements

Tasked with developing customer tooling charts to keep track of die quantities, material delivery time, die design status, FEM modeling status, tooling delivery time, forging delivery time, final machining time, and customer ship dates

Teaching Assistant – Manufacturing, Marquette University, Milwaukee, WI, Spring 2015

Taught and guided students in learning how to properly use precision measuring tools such as micrometers, calipers, gage blocks, and sine bars

Supervised and aided students in using lathes and mills in the machining process required to manufacture functioning air motors

Supervised and help students with the use of the shop laser to make cut outs and engravings for a laser project competition

Teaching Assistant – Material Selection, Marquette University, Milwaukee, WI, Fall 2013, Summer 2014, Fall 2014

Taught students how to prepare metallographic specimens in order to observe and analyze different types of microstructures

Ran tensile tests as well as hardness tests to identify the material properties of different specimens

Analyzed the ductile to brittle transition of certain steels

Looked at the age hardening of aluminum and selection of aluminum alloys

Prepared samples for each corresponding lab section – and graded lab reports

Teaching Assistant – Design of Machine Elements, Marquette University, Milwaukee, WI, Spring 2014

Taught the lab in which students analyzed several types of machine elements, both internal and external components

Ran experiments which involved the use of strain gauges, torque wrenches, chains, sprockets, gears, motors, springs, pulleys, etc.

Was involved with the revision of the semester long project report

Research Assistant, Marquette University, Milwaukee WI, Spring 2013

Became familiar with the forging software – DEFORM

oRan hot forging simulations using mechanical presses, hydraulic presses and hammers

Worked with advisor to help set up a mini – project that involved the use of the DEFORM software

oPrepared CAD models and drawings

oSet up a log book, as well as instructions for students

Co-Op, Panduit, Burr Ridge, IL, Spring 2011, Summer 2011, Summer 2012

Modified designs of air ducts, both vertical and side ducts used in data center cabinets

Prepared prototypes and tested air ducts

Analyzed the effect of perforation patterns in air ducts and Cisco equipment

Aided in the set – up of cabinets and cooling PODS
