functionality could eventually be built into the machine control to eliminate the additional hardware. Silent Tools+ adds yet another level of functionality, allowing accurate positioning of the boring bar. "One of the most difficult and critical things about using a vibration dampening boring bar is aligning the top of the insert to the centerline of the bore," Mr. Rizzie says. Instead of using a level, or even simply eyeballing it, the sensor technology provides an accurate reading of where the bar is in relation to the machine centerline, allowing the operator to rotate the bar and easily lock it in when it hits zero. e embedded sensors also have the capability of pulling data during the machining process. ey run calculations of vibration and movement. ey also monitor the temperature of the vibration damping unit, as extreme tempera- ture changes affect its operation. is data is pulled into the app and translated into necessary adjustments to improve surface quality. e app also can provide tools, such as quality control graphing, that support traceability requirements. Promos 3+ is a unit that hooks directly into the machine tool and is housed within the control cabinet. It is engineered for adaptive control capability and allows monitoring at a finite level by reading information directly from the machine such as whether it is on or off, in cycle, or in cut. It looks for patterns or anomalies that would require adjustments such as stopping the machine for a broken tool or slowing the feed rate for a hard spot in the material. It also has capabilities to handle machine maintenance function- ality, with sensors indicating when parts of the machine need attention, such as low fluid levels. Machine monitoring is a common topic of discussion, but the bigger picture is device monitoring. e machines are an important component of that, but the tools are devices as well, and they can provide informa- tion above and beyond what the machines can provide. e information gathered among these devices collaborates for better efficiency, reliability and accuracy.
