3. Project Background
There are 2 Bearings in the iGen Printer System supporting the fuser roller
Every 200,000 prints the fuser roller assembly comes in for remanufacturing
Bearing is reused a maximum of 4 times
Currently, there is no quantitative test to qualify bearings
Potentially leads to many good bearings being scrapped
Customer wishes to use the machine as a design tool

9. Data Acquisition Designed a signal conditioner to power accelerometers
Pairs with NI 6210 DAQ
DAQ outputs accelerometer readings and motor speed

Display RMS values

11. Testing Performed 10+ MSAs Refined SOP
Passed MSA using 3 bearings and 7 operators

RMS between 0.1 and 0.7 g’s
13 ranges of resolution
Differentiate ±0.025 g
Acoustic machine passed all “good” and “bad” bearings

13. Budget Overall Budget - $1500-$3000 Final Cost Breakdown
Data Collection $760.46
Physical Structure $602.91

14. Recommendations-Operations
Establish pass/fail threshold for bearings
Send a range of bearing to Arnprior
Further automate process
Use motor controller with computer input
Purchase new signal conditioner
Remove second accelerometer and drop down rails
Tyler

15. Recommendations - Hardware
Make bearing clamp out of steel
Enlarge dowel pins
Hardened shaft
Second press-fit mandrel
Larger arbor press
