1 CNC Programming / Robotic Integration Project Lead The Way Computer Integrated Manufacturing

2 CNC and TTL Programming NC Codes Sample NC Part and Program Handshaking Codes Sample Mill Handshaking Flow of Robot program Sample Robot Handshaking Program TTL I/O Wire Connections

3 NC Codes Block Number (N) Preparatory Codes (G) Miscellaneous Codes (M) Primary X Motion (X) Primary Y Motion (Y) Primary Z Motion (Z)

4 Preparatory Codes G90 - Absolute Coordinates G91 - Relative Coordinates G00 - Rapid Traverse (non-cutting move) G01 - Straight Line Interpolation (cutting move G02 - Circle Interpolation (clockwise) G03 - Circle Interpolation (c-clockwise) G04 - Dwell (wait) Pause between motions on all axis. Time in seconds - G04F2 - pause for 2 sec. G05 - Pause - waits for user intervention.

5 M Codes - Miscellaneous M00 - Pause M01 - Optional stop M02 - End of Program M03 - Spindle on M05 - Spindle off M06 - Tool Change M08 / M09 - Accessory # 1 on / off M10 / M11 - Accessory # 2 on / off

6 Sample NC Program Block N00 G90 G01 X.5 Y.5 Z0 F1 BLOCK SEQUENCE # PREP CODE - ABSOLUTE PREP CODE - SL INTERPOL Y COORDINATE X COORDINATE Z COORDINATE FEED RATE (IN/MIN)

7 SAMPLE PART ABSOLUTE COORD.

8 SAMPLE PROGRAM N00 G90 ; ABSOLUTE COORDINTAES N01 M06T1 ; LOAD TOOL 1 N02 M03 S3000 ; TURN SPINDLE ON TO 3000 RPM N03 G00 Z.1; RAPID TO.1 ABOVE PART N04 G00 X.5Y.5 ; RAPID TO POINT A N05 G01 Z-.0625F9 ; PLUNGE 1/16 AT 9 IN/MIN. N06 G01 X.5Y1.5; STRAIGHT LINE INTERP TO B N07 G01 X.875Y1; STRAIGNT LINE INTERP TO C N08 G01 X1.25Y1.5; STRAIGHT LINE INTERP TO D N09 G01 X1.25Y.5; STRAIGHT LINE INTERP TO E N10 G01 Z.1; RETRACT CUTTING TOOL

9 Sample Program Continued N11 G00 X1.75Y1.5; RAPID TO POINT F N12 G01 Z-.0625F9; PLUNG AT 9 IN/MIN. N13 G01 X1.75Y.5; STRAING LINE INTERP TO H N14 G03 X1.75Y1.5I1.75J1; CCW CIRCLE INTERP. N15 G01Z.1; RETRACT CUTTING TOOL N16 M05; TURN OFF SPINDLE N17 M06T00; UNLOAD CUTTING TOOL N18 G00X4Y3Z3; MOVE TABLE TO UNLOADING POSITION N19 M02; END OF PROGRAM SIMULATE

10 Handshaking Codes G25 - Wait until TTL output #1 (Robot) goes on G26 - Waits until TTL output #1(Robot) goes off G35 - Wait until TTL output #2 (Robot) goes on G36 - Waits until TTL output #2(Robot) goes off M25 - Sets Robot input #1 to off (Starts Robot) M26 - Sets Robot input #1 to on M35 - Sets Robot input #2 to off (Starts Robot) M36 - Sets Robot input #2 to on

11 Handshaking With The Mill M10; OPEN VISE M26; TURN ROBOT INPUT ON (RESTRICTS ROBOT MOVEMENT) G00; MOVE TO LOAD/UNLOAD POSITION M25; TURN ROBOT INPUT OFF (START ROBOT - LOAD/UNLOAD) G04 F2; PAUSE FOR 2 SECONDS M26; RESET ROBOT INPUT TO ON G25; WAIT FOR ROBOT OUT #1 TO TURN ON THEN ONTINUE M11; TURN AUX. #2 OFF (CLOSE VISE) ****** RUN MILL PROGRAM ******************** M47; REWIND PROGRAM

12 FLOW OF ROBOT PROGRAM WAIT FOR MILL INPUT LOAD VISE CYCLE OUTPUT TO MILL - CUT PART UNLOAD VISE CYCLE WAIT FOR MILL INPUT

13 Handshaking With The Robot WAIT GO TO POSITION - SAFE POSITION IF INPUT 1 OFF JUMP TO START (FROM MILL) JUMP TO WAIT START LOAD MILL VISE GO TO POSITION - SAFE POSITION TURN OUTPUT 1 ON (START MILL PROGRAM) WAIT 10 - WAIT FOR 1 SECOND TURN OUTPUT 1 OFF (LIMIT MILL TO 1 CYCLE) WAIT FOR MILL LOOP - UNLOAD VISE JUMP TO START

14 TTL I/O Cable Connection

15 Gravity Feeder Connection Connect one wire to Input #2 Connect second wire to Input Ground
