An Adaptive Control of Machine Table Reciprocation Using a Hydrophone - A Method for Improving the System Efficiency and Reliability -

Abstract:

In order to eliminate unnecessary table-over-travel of a surface grinding machine, the authors previously developed an adaptive table-reciprocation-control system using a hydrophone. The system eliminated the over-travel and reduced grinding time by 20-40%. However, during the stage of the grinding-wheel approach to a workpiece the system did not work. In order to improve the efficiency and reliability of the system, a fluid-flow stabilizer and a new coolant-supply nozzle have been developed and their performances were experimentally investigated. By using these devices, the reciprocation-control system showed its capability even during the stage of the grinding-wheel approach and this ability improved the system efficiency and reliability.
