Understanding and mastering the importance of CNC machine tools

No matter what company's CNC system has a lot of parameters, such as Japan's FANUC 6T-B system has 294 parameters. There are eight parameters for one parameter. A rough calculation of a CNC machine with a CNC system configuration has nearly a thousand parameters to set. The correct setting of these parameters directly affects the use of CNC machine tools and the performance of their performance. In particular, users can fully grasp and familiarize with these parameters, which will bring the use and performance of a CNC machine to a new level.

Practice has proved that a full understanding of the meaning of the parameters will bring great convenience to the fault diagnosis and maintenance of CNC machine tools, which will greatly reduce the time for fault diagnosis and improve the utilization of machine tools. At the same time, the parameter setting of a CNC machine tool is still a window to understand the guiding ideas of CNC system software design, and is also a reference data for measuring the quality of machine tools. Modification of parameters can also be developed if conditions permit

Some functions that the CNC system does not show when ordering CNC machine tools will help the secondary development.

Therefore, regardless of the CNC system of that model, it is very important to understand and grasp the meaning of the parameters.

In addition, it should be noted that the manufacturer of the CNC machine tool will set the relevant parameters correctly and completely when the machine tool leaves the factory, and also give the user a parameter list that fully complies with the machine settings. However, at present, this is not satisfactory, and the phenomenon that the parameter table does not match the parameter setting sometimes occurs, which brings great trouble to the fault diagnosis of the CNC machine tool in the future. Unsure of the original data and original settings, it is difficult to determine the cause of the failure during the applause, which has a negative impact on the user and the repairer. Therefore, when purchasing the CNC machine tool acceptance, the parameters brought by the random machine should be proofread with the actual settings on the machine tool. Before the service personnel of the manufacturer have left, the work should be carried out. The information must first be complete, correct, and do not understand. Despite asking questions, find out the meaning of the parameters and remove obstacles for future troubleshooting.

Before the factory machine, the CNC machine has set a number of initial parameters to match and adapt to the specific conditions of each CNC machine. Some parameters need to be debugged to determine. Parameter tables or parameter tapes for these specific parameters should be delivered to the user. In CNC maintenance, it is sometimes necessary to adjust the machine tool with certain parameters of the machine tool. Some parameters must be corrected according to the operating state of the machine tool, so the maintenance personnel should be familiar with the machine parameters. In Japan

For example, FANUC's 10, 11, and 12 systems have 26 major machine tool parameters in software. They are: parameters related to settings, timer parameters, parameters related to the controller, coordinate system parameters, feed rate parameters, acceleration/deceleration into control parameters, servo parameters, DI/DO (data input and output) parameters, CRT/MDI and logic parameters, program parameters, I/O interface parameters, tool offset parameters, fixed cycle parameters, scaling and coordinate rotation parameters, automatic corner override parameters, single release positioning parameters, user macro programs, skip signal inputs Functions, automatic tool offset and tool length automatic measurement, tool life management, maintenance and other related parameters. After the user buys the machine tool, the parameter list should first be copied and archived. One is stored in the machine's file box for the operator or maintenance personnel to refer to when using and servicing the machine. The other one is stored in the file of the machine. The correctness of these parameter settings will directly affect the normal operation of the machine tool and the full performance of the machine tool. Maintenance personnel must understand and master these parameters, and record the initial settings of the machine parameters, and keep them for maintenance.
