| 摘要 |
The invention relates to a method for supplying coolant to cutting tools (2), in which the amount of coolant is detected by flow sensors (7) and a constant amount of coolant is administered to at least one tool (2) in a speed-controlled or speed-regulated manner by means of fixed geometry pumps (3). For multiple tools (2), the administered coolant amount is hydraulically and/or geometrically divided out and kept constant according to the needs of the individual tools (2), and the dynamic pressure resulting at the tool (2) from the coolant, and resulting from the machining process, is detected and determined by comparing with tool (2) operating state reference values which are deposited in an evaluation device. The method can be applied to a switching arrangement (1), and a device for carrying out said method. Method steps with self-learning elements are carried out to deposit the reference values in the evaluation device, with an error state being characterised by a process-step-dependent rise over or fall below one or more of the reference values. |
