Method 1: Measure, Handwrite Results, Remote Da t a Entry • 37 time/motion elements, 28.9 sec./part • 62 entry errors Factors affecting accuracy and throughput: • Measurement must stop to handwrite results. • Illegible handwritten numbers,mistakes noted but not corrected, data written in shorthand and inspector's handwriting misread by the transcriber • Value can change when the inspector releases the micrometer • Data entry errors at the PC Method 2: Measure and Enter Results to PC • 20 time/motion elements: 15.3 sec./part • 4 data entry errors Factors affecting accuracy and throughput: • Alternating measuring and data entry caused errors • Caliper not seated correctly when released to key-in data • Missed data entry, incorrect keystrokes, entry to wrong cell Method 3: Measure and Enter Results Directly with Da t aSure • 17 time/motion elements: 6.6 sec./part • 0 entry errors Factors affecting accuracy and throughput: • Measurement technique is maintained • No interpretation or memory errors • Immediate, direct data entry eliminates errors WIRELESS DATA COLLECTION Methods 1 and 2 involve time-consuming hand movements to pickup and put down the tool in order to record data. Measurement with DataSure is fast and direct. The slowest method (#1) required 29 second per part with many errors. With DataSure® the same task was nearly 5 times faster – with no errors. A Da t aSure® Throughput and Accuracy Study In a controlled, 100% inspection test to measure the impact of DataSure on throughput and quality assurance,we made three measurements per part and recorded the data on 500 parts. 228 D a t a C ollection S ystems
