It is inevitable that some small problems will appear in the use of the CNC busbar processing machine. When some problems cannot be solved, we will use a method to solve them. This is also the original method to check the fault of the bus clamp, that is, the method of troubleshooting the software and hardware of the CNC busbar processing machine.
1、 Measuring the motion quality characteristics of the CNC busbar processing machine is the fault of the reduction of the motion characteristics of the machine tool. In this case, although the machine tool can work normally, it can not process qualified workpieces.
For example, the positioning accuracy of CNC busbar processing machine tool is out of tolerance, the reverse dead zone is too large, and the coordinate operation is unstable. This kind of fault must be diagnosed by the detection instrument, and then eliminated through the optimal adjustment of the mechanical transmission system, numerical control system and servo system.
2、 Whether the CNC busbar processing machine is destructive when it is presented as a fault is divided into destructive fault and non-destructive fault. It is not allowed to repeat the destructive fault, the fault that damages the workpiece and even the machine tool during repair. At this time, it can only be cleaned up according to the phenomenon when the fault occurs. The skill is difficult and dangerous.
If it can damage the workpiece, remove the workpiece and try to reproduce the fault process, but be very careful.
3、 Whether there is indication when CNC busbar processing machine presents fault can be divided into confirmed indication fault and non confirmed indication fault. Today's CNC systems are designed with perfect self diagnosis procedures to monitor the software and hardware functions of the whole system in real time. Once a fault is found, it will give an alarm immediately. Perhaps a brief text description will be displayed on the screen. Contacting the diagnosis manual equipped with the system can not only find the cause and location of the fault, but also prompt the method of cleaning up.
The machine tool manufacturer will also have relevant fault instructions and diagnosis instructions for the detailed machine tool design. The above two parts have faults indicated by diagnosis, together with various indicator lights on various electrical devices, making it easier to clean up most electrical faults.
Part of the fault without diagnosis indication is caused by the incompleteness of the above two diagnosis procedures (such as non closing switch, loose plug, etc.). This kind of fault should be analyzed and eliminated by relying on the operation process, fault phenomena and results before the occurrence of the fault, as well as the knowledge and skill level of the repair personnel on the machine tool.
4、 CNC busbar processing machine is divided into systematic fault and random fault based on the probability of fault. Systemic failure refers to the determined failure that will occur as long as certain conditions are satisfied; Random fault refers to the fault that happens occasionally under the same conditions, and the analysis of this kind of fault is more difficult.
Generally, it is related to partial looseness and dislocation of machine tool mechanical structure, characteristic drift or reliability reduction of some electrical workpieces, and excessive internal temperature of electrical devices. The analysis of such faults can be eliminated only after repeated experiments, induction and discrimination.
5、 CNC busbar processing machine is divided into hardware fault and software fault according to the location of fault. Hardware failure refers to the abnormal state and even damage of machinery, hydraulic pressure, electrical appliances, etc., which can be eliminated only after repair and even replacement.
The software fault generally refers to the fault in the PLC logic control program, which needs to input or correct some data and even correct the PLC program. Part machining program failure is also attributed to software failure.
Severe software failure is the deformity or even loss of NC system software, which can only be handled by contacting the manufacturer or its service organization.
When troubleshooting the software and hardware of the CNC busbar processing machine, we can easily check other problems of the CNC busbar processing machine, which is also more conducive to the maintenance and repair of the CNC busbar processing machine.
