Despite their simple appearance, fixtures can facilitate manufacturing processes and are intended to be quickly made. Engineering fixtures at B&G had sharpened my communication and problem-definition skills. After surveying each situation, I proposed user-friendly solutions to improve process setup time and accuracy. My work was especially important when a job became the bottleneck of the whole part.
Purpose
A flanged bolt required grade 4 surface finish and nylon pellet insert. The goal was to design a non-scratch fixture to level and correctly orient the flanged bolt for the inserting process.
Process
I designed V blocks in Solidworks from part drawings and measurements. I then 3D printed them using PLA to prevent contact damage with metal.
Product
The fixtures were made in less than a day and handed to the operator. It achieved its initial goal, and the manufacturing process proceeded smoothly.
Purpose
The test samples needed to thread into the machine with exactly 6 threads remaining. The goal was to design a fixture to verify such setup.
Process
I created a small pitch gauge by manually CADing the threads in Solidworks and 3D printing it out of PLA.
Product
This simple fixture was useful and facilitated tensile tests for 2000+ bolts.
Purpose
Operators needed to thread studs into the existing EDM fixture and ensure perfect leveling, but excessive threading lifted the fixture from the magnetic table. The goal was to design a fixture to ensure a flush setup.
Process
I proposed a simple solution of a flat steel plate bolted onto the bottom surface of the existing fixture. I created a Solidworks drawing and machined the fixture plate on a manual mill.
Product
Reduced setup time from 1 hour to 20 minutes and improved machining accuracy.
Purpose
Operators were stamping tensile test specimens free-handedly. The goal was to design a fixture that aligns the stamp with the specimen.
Process
Because the job was urgent, I quickly measured the V block dimensions, CAD the fixture in Solidworks, and 3D printed it. The fixture was bolted to the V block and provided a flat surface concentric to parts. The fixture was later machined out of steel.
Product
Improved the process speed and accuracy. Operators were happy.
Purpose
Due to retrofitting, old setup blocks were used on the new machine. The goal was to condense the 3 setup blocks into 2 by combining geometry.
Process
The old setup block dimensions were not documented in the central database, and it was especially hard to size the block's curvature. I used a caliper, micrometer, and optical comparator to find the geometry. Then, I CAD them in Solidworks and sent them for in-house machining.
Product
Simplified setup steps and tool storage.
Purpose
Due to an electronics update, the goal was to create a new panel board to house a LCD display and 2 diodes for the honing machine.
Process
I measured the original board size and hole locations with a caliper and iterated it to fit the components. Then, I CAD the new board and 3D printed it using PLA. Lastly, I modified the existing aluminum panel on the mill to fit the new board.
Product
Ensured the functionality of an updated system.
Temperature Probe Preliminary Assembly (Outside Housing)
Purpose
A CNC lathe randomly stopped once and bearing heating was suspected to be the cause. The goal was to design a device to sense bearing temperature and output data through Bluetooth to a captive portal.
Process
I employed an ESP32 & temperature probe and coded the device in Arduino. After initial testing, I soldered the components onto a perf board. Lastly, I designed and 3D printed housing for the device.
Product
The device was simple to use. Operators only needed to open their phone and connect to the ESP32 Bluetooth to see the bearing temperature. After a week of testing, the bearing temperature was concluded to be normal.
