FANUC system keyboard definitions
1 ALTER Modify programs and code (Enter an address, such as X20.0, and press this key. The address at the cursor position will be replaced by X20.0.)
2 INSRT Insert Program (Move the cursor before the address to be inserted. For example, in the program "G01X30.0Y50.0F0.08;," to insert "G99" before "X30.0," first move the cursor to "G01," then enter "G99," and press this key.)
3 DELET Delete Program (To delete an address, such as "Y50.0" in "N1G01X30.0Y50.0F0.08;," move the cursor to "Y50.0," and press this key. To delete a block of program, such as "N1G01X30.0Y50.0F0.08;," enter N1 and press this key.)
4 EOB Complete a block (END OF BLOCK) (This key is like the ";" key. It indicates the end of a program segment. This key is used to end each program segment.)
5 CAN Cancel (used in EDIT or MDI MODE)
6 INPUT Enter program and code. This is often used when entering new programs.
7 OUTPUT START Outputs programs and commands
8 OFFSET Stores tool length and radius offset values
9 AUX GRAPH Displays graphics
10 PRGRM Displays program content
11 ALARM Displays alarm content or code
12 POS Displays coordinates (Press this key to display the current position of each machine axis. Absolute and relative positions are displayed, and the display can be switched, making it very convenient.)
13 DGONS PARAM Displays self-diagnosis and parameter functions
14 RESET Returns/Stops (This key is used to reset the program after modifying a section. In PROG mode, pressing this key returns the program cursor to the top of the program. Otherwise, pressing the start button to continue processing will cause an alarm.)
15 CURSOR Moves the cursor up and down (Similar to the up, down, left, and right keys on a computer keyboard. I believe everyone is familiar with this.)
16 PAGE Scrolls pages up and down (This key is effective for screens with more than one page.)
17 O Program numbers range from O0001 to O9999 (FANUC 21i-T has special instructions. Programs between O9000 and O9999 cannot be specified as they are internal system programs.)
18 N Sequence numbers range from N0001 to N9999 (Optional. For convenience, they can be set in segments, e.g., N1 for roughing, N2 for finishing, etc.)
19 G Preparation function code
20 X-axis motion direction command
21 Y-axis motion direction command
22 Z-axis motion direction command
23 H Length compensation function code
24 F Feed command (FANUC 21i-T has special instructions. When using G98, it refers to feed in mm/min. When using G99, it refers to feed in mm/rev.)
25 R Arc radius command
26 M Miscellaneous function command
27 S Spindle speed command
28 T Tool number (I'm aware of this, usually followed by two Arabic numerals.)
29 D Radius compensation function code (I'm aware of this, usually followed by two Arabic numerals.)
30 I . J . K Distance from arc start point to arc center (on the X, Y, and Z axes, respectively)
31 P Subroutine call code
32 PROGRAM PROTECT Program memory protection switch
33 MEMORY Automatic program execution
34 EDIT Editing
35 MDI Manual editing (MANUAL DATA INPUT)
36 SINGL BLOCK Single block execution (FANUC 21i-T has the SBK switch)
37 BLOCK DELET Specifies not to execute a single block (shared with the / key)
38 OPT STOP Selective stop (shared with the M01 code) (FANUC 21i-T has the M01 switch) )
39 DRY RUN Dry run (FANUC 21i-T has a DRN switch)
40 PRG TEST Does not execute M.S.T. code commands
41 CYCLE START Cycle start (program execution)
42 CYCLE STOP Cycle stop (program pause)
43 PRG STOP Program stop (shared with M00)
44 HOME Return to the mechanical position of each X, Y, and Z axis
45 JOG Manual feed (traversing or cutting)
46 MPG Manual wheel drive
50 HIGH Manual rapid feed
51 SPDL DEC Spindle speed (RPM)
52 SPDL 100% Executes the S command speed in the program
53 SPDL CW Spindle rotation clockwise
54 SPDL STOP Spindle stop
55 SPDL CCW Spindle rotation counterclockwise
56 SPDL INC Spindle RPM Speed Increase
57 Z+, Y+, X+ Move the machine's X, Y, and Z axes in the positive direction
58 Z-, Y-, X- Move the machine's X, Y, and Z axes in the negative direction
59 4-, 4+ The machine's fourth axis
60 TRVRS Executes movement commands for each machine axis
61 CLNT ON Supply cutting fluid (COOLANT ON)
62 CLNT OFF Stops cutting fluid supply (COOLANT OFF)
63 CLNT AUTO Automatically supplies cutting fluid (COOLANT AUTO)
64 OVERRIDE Controls cutting speed from 0–150%
65 EMERGENCY STOP Emergency stop
66 THERMAL ALARM Spindle overload alarm
67 LUB ALARM Lubricant low alarm
68 X_MIRROR IMAGE X-axis mirror image processing function
69 Y_MIRROR IMAGE Y-axis mirror machining function
70 RAPID OVERRIDE Rapid Override Control
71 DNC Direct Numerical Control:
Due to the limited memory capacity of the CNC machine tool, programs are input from an external interface device, requiring simultaneous read-and-write (i.e., simultaneous program reception and execution). This is called a DNC operation. After the DNC operation is completed, the CNC machine tool's memory is lost, and the program input by the DNC is no longer in memory.
72 BACKGROUD EDIT Background Programming:
(BG-EDIT) While the CNC machine tool is performing automatic machining, another program can be input or edited simultaneously without stopping the machine.
73 MANU ABS Manual Absolute Value
74 PROG RSTAT Program Restart
75 Z NEGLT Cancels Z-axis commands
76 AXIS LOCK Cancels three-axis commands
