Mastering the setting and modification of machine parameters The CNC system is designed with great differences in the actual performance of each machine. Therefore, some parameters are specially designed. In order to make the machine operate normally, it can fully exert its working performance. The parameters must be set correctly. In the adjustment or use, maintenance, mechanical-related parameters, such as the clearance compensation amount of each coordinate axis, the positioning of the spindle, etc.; parameters related to the servo system, such as position error limit, drift compensation amount, etc.; The parameters, such as the baud rate used to transfer machine parameters and programs; these can be changed. When the parameters are modified, the parameters should be locked after the machine has achieved the best running performance.
Maximize the utilization of CNC machine tools Because CNC systems are made up of thousands of electronic devices, and their performance and longevity are highly discrete. For long-term deactivated machine tools, the CNC system should be energized or turned on for functional testing, which can greatly extend the service life of CNC machine tools. To operate and use the CNC machine tool correctly, before the start of the operation, the machine should be routinely inspected and required to operate according to the operating procedures and related systems of each machine. The failure of CNC machine tools is not as difficult to check and repair as imagined. The maintenance of CNC machine tools must first break down the working principle of each part of the system and the mechanical structure of the machine tool. Secondly, understand the operation method of the equipment, the sequence of actions and make a full investigation at the fault site. Finally, list the factors that may cause the fault. And carry out actual inspection and maintenance. Under normal circumstances, the failure of CNC machine tools is mostly caused by small problems. Pay attention to the upper and lower process of machine tool movement during maintenance, master the characteristics of the action process, make full use of the software alarm function of the numerical control system and the diagnostic function of the status display to check whether the numerical control system inputs the signal to the machine tool, whether the switching signal of the machine tool has been Input to the CNC system, etc., so that the troubleshooting is not difficult.
