Detailed Description
The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown, by way of example, to demonstrate that the invention may be practiced and that the invention may be more fully described to those skilled in the art, the technical content of which will be more clearly understood and appreciated. The present invention may be embodied in many different forms of embodiments, and the scope of protection is not limited to the embodiments described herein, which are illustrative rather than restrictive in nature. In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views.
The invention is further described below with reference to the figures and examples.
A preferred embodiment of the present invention provides a method for monitoring cutter breakage of a numerical control milling machine, including: the invention provides a method for monitoring cutter breakage of a numerical control milling machine, which comprises the following steps:
s1: installing cutter measuring devices on cutter shafts of the milling machine, wherein the cutter measuring devices correspond to the cutter shafts one by one;
s2: the cutter detecting circuit is connected, and a signal is given out according to the on-off of the cutter detecting circuit to judge whether cutter breakage occurs or not;
s3: if the power supply signal appears, judging that the cutter is broken; otherwise, judging that no knife break occurs;
s4: tracking and recording the power supply signal and sending a machine alarm prompt;
s5: searching and analyzing the record for a knife-breaking alarm signal at intervals and identifying the knife-breaking alarm signal;
s6: transmitting the identified information to a monitoring computer terminal;
s7: the quality testing personnel receives the information and carries out on-site processing;
s8: and returning to the computer end for confirmation after the treatment is finished, and finishing the treatment.
And step 9: and the computer end records the confirmation time, the confirmation personnel and the inspection state.
In this embodiment, the blade measuring device in step S1 is a contact blade measuring device.
