Active coolant flow control for machining processes

摘要

A method for operating a machining tool, comprising: setting a flow rate and a pressure of a flow of coolant to a target flow rate and a pressure target, respectively, the coolant flow being provided to the machining tool; machining a work-piece using the machining tool; measuring the flow rate and the pressure of the flow of coolant; and detecting an anomaly with respect to the coolant flow; and taking a corrective action depending on the type of the detected anomaly.

1. A method for operating a machining tool, the method comprising:
setting a flow rate and a pressure of a flow of coolant to a target flow rate and a pressure target, respectively, said coolant flow being provided to said machining tool; machining a work-piece using said machining tool; measuring said flow rate and said pressure of said flow of coolant; and detecting a first anomaly when at least one of said measured flow rate and said measured pressure deviates from said target flow rate and from said pressure target, respectively, by a first predetermined amount, and taking a first corrective action comprising triggering an alarm while allowing said machining of said work-piece to continue; and detecting a second anomaly when the at least one of said measured flow rate and said measured pressure deviates from said target flow rate and said pressure target, respectively, by a second predetermined amount greater than said first predetermined amount, respectively, and taking a second corrective action comprising stopping said machining of said work-piece.
