Coolant control system, numerical control machine tool and processing method

Abstract

The invention provides a cooling liquid control system. The cooling liquid control system comprises an input device, a control device, a machine tool cooling control device, an RS232 connecting cable and an I / O (Input / Output) control signal line, wherein the input device is connected with the machine tool cooling control device through the control device and is used for performing human-computer interaction to set cooling liquid control parameters; the control device is used for controlling turn-on or turn-off of the machine tool cooling control device according to an input control signal of the input device; the input device is connected with the control device through the RS232 connecting cable; the control device is connected with the machine tool cooling control device through the I / O control signal line. The invention also provides corresponding numerical control machine tool and machining method. The control device can be used for automatically recognizing a non-cutting numerical control tool path and an empty path, accurately controlling the cooling liquid spray-out time and reducing the using amount of cutting oil. A touch screen of the input equipment can receive modification of an F value by a user, namely modification of time, so larger flexibility is realized.

Description

technical field [0001] The invention relates to mechanical processing technology, in particular to a cooling liquid control system, a numerically controlled machine tool and a processing method. Background technique [0002] The processing of many large arc parts (wall panels) in the field of aviation and aerospace is completed by numerical control programs. However, due to the particularity of the design and process requirements, the part mainly presents the following two main problems during the processing: figure 1 As shown, due to the particularity of the design and process requirements, in order to ensure the theoretical contour line 1, the CNC tool 3 passes the tool path 2 four times, and the first three paths are almost empty cutting. However, the CNC machine tool cannot automatically recognize that the first three paths are empty cutting, and the cooling system is always on, resulting in a large waste of coolant. Such as image 3 As shown, due to the large area of...

AI Technical Summary

Problems solved by technology

The CNC tool moves from the characteristic position A to the characteristic position B. The CNC machine tool cannot automatically recognize that this path is dry running, and the cooling system is always on, resulting in a large waste of coolant.

Based on the cooling system of CNC machine tools, it has been running from the beginning of the program, and cannot automatically identify whether the tool path is running dry, resulting in a large waste of coolant and polluting the environment.
