Introduction to the Self-Repair System of Large CNC Machining Centers
The self-repair system of a large CNC machining center refers to the setup of backup modules within the system, along with self-repair programs installed in the software of the CNC system. When this software is running and detects a fault in a certain module, the system displays the fault information on the CRT while automatically searching for available backup modules. If a backup module is found, the system can automatically take the faulty module offline and connect the backup module, allowing the system to quickly return to normal operation. This solution is suitable for automated work environments without human supervision.
Comprehensively analyzing a fault phenomenon is an important factor in determining whether the judgment is correct, according to China Material Recycling Network. Before searching for the cause of the fault, it is necessary to understand the following situations: whether the fault occurred during normal work or immediately after startup; whether it is the first occurrence or has happened multiple times; and confirming the correctness of the machine tool processing program. It should be noted that some faults in actual use of the machine tool have no alarms and are not very obvious. Handling such faults is not that simple. Additionally, some equipment malfunctions without any alarm information and lacks relevant maintenance documentation. For diagnosing and handling these types of faults, it is necessary to carefully inspect based on specific conditions and analyze from subtle phenomena to find the true cause. To identify the cause of such faults, one must first determine the real fault phenomenon from various surface phenomena and then find the cause from the confirmed fault phenomenon.
