As the swift and violent development of change quickly of numerical control technology, FANUC system had updated much generation, compare advanced FANUC Oi-T set to now from original FANUC 15M. Partial engineer learns the operation that mastered newest system to debug a method, because the data is as not complete, bigger as existing system difference,meet when meet unexpectedly compares old FANUC system and feel answer hard. And the numerical control facility that place of domestic major medium and small businesses owns now, its system is older system, be like: FANUC 15M (16M and 18M) . 1, equipment debugs the problem that appears in the process my company job shops purchased machinist of Taiwan tall blessing 2003 machining center of JET-40H of Inc. of course of study vertical, configure workbench of CNCT-40JF of Inc. of machine of essence of extend grand international, machining center uses FANUC 18M to control a system, for 5 axes (axis of X, Y, Z, A, C) vertical treatment controls a center, join PC port is RS232 port. Because company staff is fluctuant, have sex not complete, cause this machining center to debug the data backup after finishing to lose. And the account that handles this by accident because of operation personnel, cause machining center all programs and parameter are all and missing. And the backup that can find data leaves factory for equipment the backup of moment, although major parameter can be used, but to normal treatment, have individual parameter or adjust so that undertake. The 2, memory in debugging storage of data of measure 　 CNC to get stuck wears the following data: CNC parameter, PMC parameter, pitch error is compensation cost, custom-built grand process of cost of compensation of variable value, cutting tool, assembly (machine program, custom-built grand program) . Among them the core parameter that CNC parameter, PMC parameter is machining center, it is machining center can undertake machining a movement, the action between each axis won't appear the assurance of interference. Need to export these data I/O equipment when control equipment runs normally beforehand. Input parameter software uses PCIN software 4.

2 version, the setting is COM1 mouth, baud rate is used 4800, data for 7, stop for 2. 2.

1Parameter of CNC of 　 of CNC parameter input regards numerical control as one of more important parameter in the system, can choose to be in usually most begin level to transmit this parameter. Its input condition to be a choice urgent suspend status, the parameter that affirms data-in place needs does not have a mistake, concrete move is as follows: Press OFFSETSETTING key several times above all, press again SETING 〕 of soft key 〔 (set) , occurrence set screen. Affirm " PARAMETER WRITE(parameter is written) =1 " . Press SYSTEM bolts next, choose parameter screen. Use the R232 that string together a mouth to transmit data, all parameter all are systematic acquiesce parameter, but notice 0103 parameter, lead set parameter to transmit baud. If rate of numeric and corresponding baud is expressed 1. After choosing good baud to lead, press continue dish single bond, usually rate of acquiescent transmission baud is 9600, 0103 values input is parameter 11. Press finally soft key of 〔 READ 〕 , press 〔 EXEC 〕 bolts again, begin to input parameter. After the input that waits for parameter ends, for a time dump, next again electrify. 2.

2In system of numerical control of PMC parameter input, PMC parameter namely PLC echelon graph, in having numerical control system, logistic control, time control reachs the parameter of the multinomial control function such as computation control. Its input condition to be a choice urgent suspend status, concrete move is as follows: Above all, shut (key of KEY4=1) program protection, press function key OFFSETSETTING, press again soft key of 〔 SETING 〕 , occurrence set screen. Affirm " PARAMETER WRITE=1 " . Next, press function key SYSTEM, press again soft key of 〔 PMC 〕 . Press soft key of 〔 PMCPRM 〕 , press again soft key of 〔 KEEPRL 〕 . cursor alignment is in " K900/K17 " on, set the first for " 1 " . Input 0 000001 0INPUT. So far, data of make choice of inputs the screen that ／ outputs. Finally, press return dish single bond, press again continue dish single bond. Press 〕 of I/O of soft key 〔 , undertake concerned inputting the parameter set of ／ output. Be in " CHANNEL " entry point, key in 1 INPUT, the passageway that chooses to input ／ to export equipment 1. Be in " DEVICE " place, press 〔 FDCAS 〕 , choose floppy disk. Be in " FUNCTION " place, output data, press soft key of 〔 READ 〕 . Press 〕 of EXEC of soft key 〔 , begin to input PMC parameter. 2.

3 pitch compensate a value to input every machining center to be much axle control, undertake machining, because mobile precision of the axis is the treatment precision control that relies on guide screw, and because the treatment of guide screw machines the element of craft and processing technique, accomplish the pitch just the same of every guide screw impossibly, can undertake by numerical control system precision is controlled only so, thereby some pitch compensate a value, the pitch compensation cost of every machining center is average different, this value has been debugged when equipment leaves factory by equipment manufacturer commonly. To assure the precision of machining center, reason compares important parameter the pitch compensation cost of machining center also is machining center. Pitch compensates the measure that is worth an input to be as follows: Above all, loose and urgent stop pushbutton, in the choice EDIT mode falls. With go up entry affirms set screen identically " PARAMETER WRITE=1 " . Press function key PROG, press again 〕 of PRGRM of soft key 〔 (program) , occurrence program content displays screen. Press again soft key 〔 () of 〕 of OPRT) 〕 , 〔 F SRH, press 〕 of EXEC of 3, 〔 , choice pitch error amends the document of the value. Next, press function key SYSTEM several times, press again 〕 of PARAM of soft key 〔 , 〔 PITCH 〕 , the set screen that occurrence pitch error is worth. Press soft key 〔 (OPRT) 〕 , press again key. Press soft key of 〔 READ 〕 , press 〔 EXEC 〕 bolts again, begin to input pitch error to compensate a value. Etc read after taking an end, press function key OFFSETSETTING 2 second, occurrence set screen, will " PARAMETERWRITE " set afresh for " 0 " . 2.

Machining center of input of 4 grand orders uses grand program to be custom-built grand program, and do not alter commonly in treatment, personnel is debugged to set grand program before equipment investment is used for No.

9000 to No.

9999, protection was installed to command parameter in system of this paragraph of order, and initiative it is to be in protective condition, transmit these grand programs to be able to appear directly the system calls the police clew. Modification parameter NO3202#4 can conceal your 9000~~9999 program. The PASSWD after parameter of machining center reply is worth for 0, need to revise the cost of NO3202#4 only so, can transmit No.

9000 to No.

The block of 9999. Specific input move is as follows: In affirm the case that has chosen EDIT way falls, shut (key of KEY2=1) program protection, press function key PROG, press again 〕 of PRGRM of soft key 〔 , occurrence program content displays screen. Next, press soft key 〔 (OPRT) 〕 key, number of program of input O (O) (for instance 9000) , press soft key of 〔 READ 〕 , press 〔 EXEC 〕 bolts again, begin an input custom-built grand variable is worth. Program number assigns the number that has not use. After the input is finished, choice machine tool operates the MEMORY way of face plate, press the loop begins pushbutton. When executive program, grand variable is worth namely by set. Press function key OFFSETSETTING is mixed continue dish single bond, press again 〕 of MACRO of soft key 〔 , appear custom-built the indication screen of grand variable. Press NO SRH 〕 of 〔 of 9000 soft key, show variable number 9000, maintain truly make grand variable be worth already correct set. 2.

Equipment of 5 machining center is debugged, after calibration inputs a system with grand program in machining center parameter, after input MDI is appointed, machining center can be run normally. But still need to adjust machining center the origin of each axis, and machine origin. The grand process work of this equipment is a basis origin of treatment coordinate department is a basis, so must coordinate of calibration workpiece treatment fastens origin. Specific debug measure to be as follows: (1) adjust position of origin of machining center machinery. Below type of hand movable mould, treatment axis of workbench X, Y and Z axis move proper place, modification parameter 1815#5#4 is worth, axis of X, Y, Z the value repairs instead 1. Cut off the power restart system, criterion setting of machining center origin ends. (2) adjust machining center backlash. Secure dial gauge base the position that moves together in disaccord axis, the watch head wearing is in workbench is fiducial the position, below handwheel mode, with fold × 10 shake to a direction slowly move handwheel, write down the numerical value that next handwheel rotate, and affirmatory workbench moves to a direction. Shake to opposite way again move handwheel, when writing down next workbench to move for the first time reversely, what handwheel has rotated is numeric. Go to 10 inputs of this numeric × next in the axial parameter with 1851 corresponding parameter. (3) adjusting machining center to machine coordinate is origin. When this machining center is being designed at the outset, of grand program writing is a foundation to write according to treatment coordinate department, machining treatment coordinate is origin (namely opposite origin) numerical value also is a more important parameter. Overfulfil is debugged and after adjusting, machining center basically had the function that workpiece machines. In the process that processes work in machining center, may appear when machining workpiece circular arc, circular arc center can appear step perhaps appears circuit groove. Appear because be when treatment circular arc,this kind of circumstance is, mobile X axis is changing to when, systematic axis compensates a value (backlash compensates a value) incorrect, need readjust machining center or the backlash value of equipment axis.
