In the past, quality inspectors used laser light gages to determine physical parameters such as roughness and waviness. They then compared these measurements to manufacturing and customer guidelines. If a part or group of parts fell outside the standards set for the process, a complete rebuilding of the spindle machinery was usually required. This after-the-fact measurement of quality became increasingly objectionable because of the costs associated with repair, downtime, and rework.
Tests to determine if a correlation existed between the quality of the machined surface and spindle machine vibration revealed that product quality could be predicted by measuring vibration acceleration. So, plant personnel established new limits that reduced product rework by 93%. The new limits also helped eliminate some root problems in the machinery that were previously unknown to company engineers.
