CNC machine tools are also referred to as personal computer machine tools. In an effort to make the

What would be the CNC data: CNC makers, machine tool companies, customers from the composition of your CNC program, we realize that the FANUCCNC method software program involves:

Interpolation handle software: control trajectory calculation;

Digital servo application: handle the position, speed and motor current of the machine tool, accurately and immediately handle the servo feed movement;

PMCLADDER editing software program: employed to compose ladder diagrams, comprehensive the handle of manage panel, auxiliary functions and also other switching actions;

Communication software program.

delete partition flash drive is created by engineers of Japan FANUC Research Institute. For users of CNC systems (generally referring to machine tool factories), generally only the machine parameters (PARAMETER) and ladder diagram (LADDER) must be developed. For machine tool users, NC programs and tool parameters are their major CNC files.

Therefore, CNC data mostly incorporates method software program, machine tool parameters, ladder diagram, NC system, tool parameters and so on.

Exactly where does CNC information exist: it is divided into two categories. The data pointed out above is divided into two categories based on the memory (CNC_MEM): SYSTEMDATA and SRAMDATA.

1. SYSTEMDATA: placed in FROM

Including method files and MTB files (MachineToolBuilder, machine tool factory). The system file is the above CNC technique software program, as shown in Table 1, and also the MTB file refers towards the PMC ladder diagram and P-CODE macro program developed by the machine tool factory. These two kinds of data are stored in the FROM on the key board with the CNC program.

2. SRAMDATA: placed in SRAM

Including CNC parameters, machining applications, pitch error compensation values, macro applications, tool compensation values, PMC parameters (Timer, Counter, Keeprelay, Datasheet) along with other user files. As deleted partition recovery software implies, this type of information is stored in the SRAM around the major board with the CNC technique.

Different information is stored in unique memories, as shown in Figure 1.

Figure 1 Unique data is stored in distinct memories

The data in FROM is reasonably steady, and it truly is not uncomplicated to shed beneath standard circumstances. Nevertheless, if the CPU or memory board is replaced, the data in the FROM can be lost. Amongst them, program files usually don't really need to be backed up (but can't be simply deleted), because FANUC can provide a technique file writing service, and MTB files must be backed up, because this is a file of your machine tool factory, FANUC firm will not know, and machine tool factory Be sure to hand more than the PMC system towards the finish user. Such files could be stored using a memory card.

The information in SRAM demands battery protection after power off, and it truly is volatile, so it really is essential to retain the information. At the exact same time, the information of each CNC machine tool is special, due to the fact even the identical kind of machine tool, the machine information may be diverse, like servo parameters, pitch error compensation data, and even PMC parameters, and so forth. These information can be installed and commissioned by personnel Modified or adjusted in accordance with the precise scenario on site. After the parameter misoperation happens, if you need to restore the original value, if there is no detailed and accurate record to check, and there's no data backup, it is going to bring about far more critical consequences.

As a result, the MTB files in the FROM plus the user files in the SRAM have to be backed up by users with the CNC system by means of media such as memory cards (CF cards) or U disks.

What to perform if CNC information is lost: Backup / Restore 1 Under what situations is data backup / restore expected? The so-called data backup (backup), which is, the information files in the CNC are output to peripherals (for example memory cards, private Computer difficult drives, and so forth.) for information backup, after the information within the CNC is lost or the method has computer software Failure, it is possible to use the backup information to restore the information (restore) and get rid of the soft fault, thereby restoring the operation with the CNC machine tool. For the commissioning of new machine tools, the restoration of information is also known as data loading.

√ The CNC program will be paralyzed resulting from long-term idle of the machine tool, battery failure, and operating errors on the operator. Within accidentally deleted hard drive partition , the CNC system have to be reinstalled and adjusted.

√When the system is initially installed or when the current servo drive and servo motor are replaced, or when the servo parameters are incorrect resulting from battery replacement, etc., the servo will have to be initialized and readjusted. Otherwise, the CNC program can not communicate together with the existing hardware and software.

2 What will be the techniques for data backup / restore? You'll find distinctive methods of information backup and recovery at diverse stages of technological improvement. At present, by far the most commonly used strategies are mostly RS232 communication and memory card (or U disk) input / output, as shown in Figure two.

Figure 2 Diverse information backup / restore methods may also be transmitted through the Ethernet port. The FANUC system 0iC / D and 0iMate-C / D are equipped with Ethernet ports. As shown in Figure three, the white interface could be the Ethernet port utilised by the American CentroidCNC for large file transmission.

Compared with all the RS232 mode, the use of a memory card can save the fatigue of carrying a computer about the CNC machine tool website, and also you do n’t need to worry about the incompatibility on the transmission software program and also the harm from the data line. You no longer have to be concerned about insufficient technique memory for operating big processing programs .

three What tools are needed for data backup / restore? The FANUC system 0iC / D and 0iMate-C / D all give PCMCIA slots. Inserting a memory card can conveniently back up or restore several method data. FANUC0iMate-D can also be equipped with a USB interface, as shown in Figure four.
