Detailed Description
The control method of the present embodiment is used for controlling a numerical control machine tool such as that shown in fig. 1.
Referring to fig. 1, the numerical control machine tool comprises a machine tool shell 3 with an opening and a safety bin door 4 which completely covers the opening in a closed state, wherein the machine tool shell 3 and the safety bin door 4 in the closed state enclose a closed machine tool space to isolate an internally mounted processing device, so that dangers caused by the operation of each cutter in the operation of the machine tool are avoided, and the safety of the operation of the machine tool is improved.
The safety door 4 has a threshold module 1, and the threshold module 1 includes a door lock for restricting the safety door 4 in a closed state and a door opening sensor for sensing whether the safety door 4 is opened.
Referring to fig. 2, after the numerically controlled machine tool is started, the numerically controlled machine tool is normally operated in a safety door lock mode, in which when the door opening sensor senses that the safety door 4 is in an opened state, the operation of a processing device of the numerically controlled machine tool is prohibited to prevent a general machine tool operator from generating danger during the use of the machine tool, and when a professional technician needs to debug the machine tool, shielding software is operated to adjust the numerically controlled machine tool to a safety door lock shielding mode, in which a processing device of the numerically controlled machine tool is allowed to operate under the condition that the safety door 4 of the numerically controlled machine tool is opened, so that the technician can adjust and test the operation of the machine tool in this mode, but in order to reduce the danger after the safety door 4 is opened, in this embodiment, when the numerically controlled machine tool is operated in the safety door lock shielding mode, the speed of feeding each tool of the processing device to the spindle is limited, the danger of technical personnel caused by collision of the technical personnel due to the movement of the machine tool is avoided.
It should be noted that, in order to prevent misuse of the masking software by other people, in this embodiment, the operation of the masking software needs to pass through an authentication device, which may be a conventional password authentication device, a fingerprint authentication device, a voiceprint authentication device, or the like.
After the numerically-controlled machine tool runs in the safe door lock shielding mode for X time, the debugging of the numerically-controlled machine tool is considered to be possibly completed, wherein X is the debugging time of the conventional numerically-controlled machine tool, a user can adjust the debugging time according to actual experience, and X in the embodiment is defaulted to 30 minutes.
When the numerical control machine tool runs for more than X time, the door opening sensor detects that the safety bin door 4 is closed, the numerical control machine tool is controlled to return to the safety door lock mode, the machining device is forbidden to run when the safety bin door 4 is opened, danger to operators is avoided when the machining device runs, the limitation on the feed shaft speed of each machining device is removed, and the machine tool runs at full speed.
It should be noted that:
the method used in this embodiment can be converted into program steps that can be stored in a computer storage medium, and is implemented by being called and executed by a controller of the numerical control machine.
