Modern CNC machine tools gradually to high-speed, high efficiency, high precision, composite and other functions in the direction. In a high-speed and complex machine tools to ensure efficient production, safety and reliability is a necessary condition. Therefore, the evaluation of the merits of a machine, not only need to see how powerful its functionality, but also need to pay attention to how high the safety performance. Improve the safety performance of CNC machine tools, both to reduce production accidents, protect personnel and machine safety, improve the added value of their products.
1 NC machine emergency stop and overtravel circuit analysis
CNC machine tools often use the emergency stop button and overtravel to ensure that in case of danger, so that CNC machine tools can quickly stop; can be used safety door guard, such as with or without latching mechanical latch switch to prevent Personnel are free to enter dangerous areas to ensure that maintenance personnel operate safely in hazardous areas; the safety monitoring speed function can be used to debug the use of buttons and electronic handwheels to monitor the speeding and stopping of machines and to ensure that personnel open the safety gates Debug the machine safely. CNC machine tool emergency stop and overtravel processing is an important part of the safety of CNC machine tools, a machine tool acceptance and use must be involved in these two aspects.
In the FANUC CNC system applications, emergency stop and over-travel have the following conventional treatment.
