Preformed Line Products
I worked as a Mechanical Engineer at Preformed Line Products (PLP). PLP is a designer, manufacturer and integrator of high quality cable assemblies and control hardware systems.
​
At PLP I designed and modified cable line assemblies in CREO to meet existing customer specifications and new product requests.
I created torque fixtures to expedite the manufacturing process and saved the company around 1100 annually.
When product deviations would occur I analyzed them by creating 3D CAD animations. When there was still ambiguity from the animations I would design a mock-up fixture and work with the machine shop to create a physical fitting.
​
I also preformed a Null-Hypothesis statistical analysis for break load wire lot skipping. I put the information into a report and presented the data to senior management. This process would save the company an estimated 6.75 hours of labor and $220 per wire lot.

Note that all projects displayed are non-proprietary and I have been give permission to use them.
Torque Fixture
I designed a torque fixture that would allow all torque wrenches to be calibrated in house, barring a single master wrench. Previously the company would send out all their wrenches for calibration, costing around 1100 dollars annually.
​
​
This Fixture would allow a variety of different loading torques, as there would be several various inserts for different bolts. If an insert would to be broken from over torquing or if the threads were stripped, it would be easy and cheat to replace, since the fixture itself would not be damaged. The fixture was also designed to be easy to machine and with existing shop materials.

Product Deviation Analysis
Whenever a product deviation occured I would preform analysis on it by creating 3D cad animations to see if the product would still fit according to customer specification. The video to the right is an example of work I did.
If the animation would not suffice, due to ambiguity of a tight fit, I would design a physical mock-up and work with the machine shop to make it. See the photos below for an example.
Designing and Modifying Assemblies
I designed and modified numerous cable assemblies to meet customer requests. Below are a couple examples of work I did.

Statistical Analysis of Break Load Wire Lot Skipping
I performed a null hypothesis analysis that compared our break load wire data to a competitors. The goal of this test was to prove that the mean of our break load wires was the same as our competitors and thereby utilize the same wire lot skipping process they have started.
Implementing this process will have an estimated savings of 6.75 hours of labour and 220 dollars per lot. This is quite alot considering we have to run one lot a week, and would save a large amount of resources on the quality assurance side.
​
The analysis itself involved using a two sample t-test assuming unequal variances for all the different wire diameter stock we had. The report and data are linked below.
