SPOILER ALERT!
CNC machine tools are also called pc machine tools. As a way to make the machine tools operate reliably and with higher overall performance, there need to be a lot of data assistance. What will be the CNC information? Where does each and every exist? What
What are the CNC data: CNC manufacturers, machine tool makers, customers in the composition from the CNC system, we realize that the FANUCCNC program computer software consists of:
Interpolation control application: manage trajectory calculation;
Digital servo computer software: control the position, speed and motor present in the machine tool, accurately and swiftly control the servo feed movement;
PMCLADDER editing application: employed to compose ladder diagrams, complete the control of manage panel, auxiliary functions along with other switching actions;
Communication software program.
The above software is developed by engineers of Japan FANUC Investigation Institute. For customers of CNC systems (commonly referring to machine tool factories), generally only the machine parameters (PARAMETER) and ladder diagram (LADDER) need to be created. For machine tool customers, NC applications and tool parameters are their major CNC files.
Thus, http://download.cnet.com incorporates method software program, machine tool parameters, ladder diagram, NC plan, tool parameters and so on.
Where does CNC information exist: it truly is divided into two categories. The information talked about above is divided into two categories according to the memory (CNC_MEM): SYSTEMDATA and SRAMDATA.
1. SYSTEMDATA: placed in FROM
Including method files and MTB files (MachineToolBuilder, machine tool factory). The technique file will be the above CNC program software, as shown in Table 1, and also the MTB file refers to the PMC ladder diagram and P-CODE macro system created by the machine tool factory. These two varieties of information are stored inside the FROM around the major board of the CNC program.

two. SRAMDATA: placed in SRAM
Such as CNC parameters, machining programs, pitch error compensation values, macro programs, tool compensation values, PMC parameters (Timer, Counter, Keeprelay, Datasheet) and also other user files. Because the name implies, this kind of information is stored within the SRAM around the major board from the CNC method.
Diverse data is stored in unique memories, as shown in Figure 1.
Figure 1 Various information is stored in distinctive memories
The data in FROM is reasonably steady, and it is actually not easy to drop under normal circumstances. However, in the event the CPU or memory board is replaced, the data in the FROM might be lost. Among them, program files usually don't must be backed up (but cannot be conveniently deleted), simply because FANUC can supply a program file writing service, and MTB files have to be backed up, because this can be a file in the machine tool factory, FANUC firm does not know, and machine tool factory Be sure you hand over the PMC plan towards the finish user. Such files is usually stored with a memory card.
The data in SRAM desires battery protection soon after energy off, and it is actually volatile, so it can be essential to retain the data. At the similar time, the information of every single CNC machine tool is unique, mainly because even the identical kind of machine tool, the machine information could be different, such as servo parameters, pitch error compensation data, and even PMC parameters, and so on. These data may very well be installed and commissioned by personnel Modified or adjusted as outlined by the precise scenario on website. After the parameter misoperation occurs, if you need to restore the original worth, if there isn't any detailed and correct record to verify, and there's no data backup, it's going to lead to extra critical consequences.
As a result, the MTB files in the FROM as well as the user files in the SRAM should be backed up by customers of your CNC system by means of media like memory cards (CF cards) or U disks.
What to accomplish if CNC data is lost: Backup / Restore 1 Beneath what situations is data backup / restore necessary? The so-called data backup (backup), which is, the data files inside the CNC are output to peripherals (which include memory cards, personal Computer tough drives, and so on.) for information backup, when the information within the CNC is lost or the program has software program Failure, you could use the backup data to restore the data (restore) and get rid of the soft fault, thereby restoring the operation in the CNC machine tool. For the commissioning of new machine tools, the restoration of information can also be called information loading.
√ The CNC system will probably be paralyzed because of long-term idle of the machine tool, battery failure, and operating errors on the operator. In this case, the CNC program ought to be reinstalled and adjusted.
√When the method is initially installed or when the current servo drive and servo motor are replaced, or when the servo parameters are wrong as a result of battery replacement, and so on., the servo need to be initialized and readjusted. Otherwise, the CNC system cannot communicate together with the current hardware and software.
two What will be the procedures for information backup / restore? You will discover different approaches of information backup and recovery at diverse stages of technological improvement. At present, one of the most usually made use of strategies are mostly RS232 communication and memory card (or U disk) input / output, as shown in Figure 2.
restore deleted partition / restore methods can also be transmitted via the Ethernet port. The FANUC technique 0iC / D and 0iMate-C / D are equipped with Ethernet ports. As shown in Figure 3, the white interface is the Ethernet port utilized by the American CentroidCNC for substantial file transmission.
Figure 3 US CentroidCNC file transfer interface
Compared together with the RS232 mode, the use of a memory card can save the fatigue of carrying a personal computer about the CNC machine tool web-site, and you do n’t must worry about the incompatibility from the transmission application and also the harm from the information line. You no longer have to worry about insufficient method memory for running significant processing programs .
three What tools are necessary for information backup / restore? The FANUC program 0iC / D and 0iMate-C / D all deliver PCMCIA slots. Inserting a memory card can very easily back up or restore different program data. FANUC0iMate-D is also equipped with a USB interface, as shown in Figure four.
