Examples: G00 X0.0 Z0.0

G01 Linear

A G01 causes linear motion t the position at the last specified feedrate form the current position. The feed rate for the linear motion should be mentioned in the part program .

Examples: G01 X30.0 Z-1.0 F100.0

G01 X0.0

G02 Clockwise Arc

A G02 causes a clockwise arc to the specified position.

Example: G01 X20.0 Z-10.0 F120.0

G03 X30.0 Z-15.0R5.0

G02 X40.0 Z-20.0 I5.0

Example: G01X20.0 Z-10.0 F120.0

G03 X30.0 Z-15.0 R5.0

G03 X40.0 Z-20.0 K-5.0

G04 Dwell

AG04 causes the program to wait for a specified amount of time.

This can be used for drilling cycles. Because the drilling cycle requires time delay to finish the already drilled hole. The time can be specified in seconds with the "X" or "U" prefixes or in milliseconds with the "P" prefix.

Examples: G04X1.5

G04U1.5

G04 P1500

G20 ImperialA G20 causes position to be interpreted as being in imperial units. All the input values are inches.

This can only be set at the start of the main program.

G21 Metric

A G21 causes positions to be interpreted as being in metric units (MM).

This can only be at the start of the main program. By default Metric Units will be taken for programming.

G28 Goto Reference Point

A G28 causes a fast traverse to the specified position and then to the machine datum.

Examples : G28 X34.0 Z5.0

G28 U0.0 W0.0

G40 Cancel Compensation

A G40 cancels tools nose radius compensation.

G41 Compensate Right

A G41 enables tool nose radius compensation to the right of the programmed path.

G42 Compensate Left

A G42 enables tool nose radius compensation to the left of the programmed path.

G50 Co-ordinate Setting

G50 enables tool nose radius compensation tot he left of the programmed path.

G50 has 2 users.

A coordinate setting block has ab "X", "Z", "U" or "W" upon it.

A maximum spindle speed block does not.

G50 Clamp Spindle G50 sets the maximum spindle speed for constant surface speed control.

An "X", "Z", "U" or "W" prefix must not be on the block or it will be interpreted as a coordinate setting block.

Example : G50 S2000

G50 creates a new coordinate system in which the tools current position is set to the specified coordinates.

The new coordinates can be in absolute or incremental form.

Example:

G50 X0 Z0

and

G50 U-40

G70 Finishing Cycle

AG70 causes a range of blocks to be executed, then control passes to the block after the G70. This will be used after the completion of the Roughing Cycle.

The "P" and "Q" values specify the "N" block numbers at the start and end of the profile.

Example : G70 P10 020

P - First Block of cycle

Q - Last Block of cycle

G71 Multiple Turning

A G71 causes the profile to be roughed out by turning. Control passes on to after the last block of the profile.

Two G71 blocks are needed to specify all the values.

Example : (i) G72U2.0 R1.5

(ii) G71 P.0 Q20 U0.1 W0 F45

specifies a depth of cut (radius) of 2 and an escape of 1.5.

(i) U0.5 R1

U( Depth of cut in mmR( Retraction (or) Retardation amount in mm(ii) G71 P Q U W F

P( Starting block number (i.e) first block of the cycle

Q( End of the Programme

U( Finishing allowance along X axis in mm W( Finishing allowance along Z axis in mm F( Feed rate

G71 P10 Q20 U1.0 W1.0 F45The "P" and "Q" values specify the "N" block numbers at the start and end of the profile.

The "U" and "W" specify the distance and direction of the finishing allowance on the X and Z axis.

G72 Multiple Facing

A G72 causes the profile to be roughed out by facing. Control passes on to after the last block of the profile.


W - Depth of cut in each pass in Z axis

R - Retraction (or) Retardation amount in mm.

Example: G72 W2.0 R1.5

Specifies a depth of cut of 2 and an escape of 1.5.

G72 P10 Q20 U1.0 W1.0

The "P" AND "Q" values specify the "N" block numbers at the start and end of the profile.



The "U" and "W" specify the distance and direction of the finishing allowance on the "X" and "Z" axis.

U - Finishing allowance in X axis

W - Finishing allowances in Z axis

G73 Pattern Repeating'

A G73 causes the profile to be roughed out by displacing the profile. Control passes on to after the last block of the profile. Normally this cycle can be applied for casting blocks.


Examples:

G73 U3.0 W4.0 R5

Specifies an X axis relief of 3.0 (radius) a Z axis relief of 4 and 5 cycles.

G73 P1 Q2 U3.0 W4.0

The "P and "Q" values specify the "N" block numbers at the start and end of the profile.

U - Distance and direction of Relief amount in the X axis radius designation

W - Distance and direction of relief amount in the Z axis radius designation

The "U" and "W" specify the distance of the finishing allowance on the X and Z axis .

R - No. of panes



U - Finishing allowance in X axis

W - Finishing allowance in Z

F- Feed rate axis

G74 End Face Peck Drilling G74 is a Z axis pecking cycle.

G81 Drilling CycleA G81 is a drilling cycle.

An explicit specified G81 will

linear to new position

Fast traverse to start position.

A modally specified G81 differs in that it will first travel linear traverse to the given depth, after machining it will retract to the initial position to rapid traverse.

If only an X axis value is entered then grooving will be performed.

If only a Z axis value is entered then drilling will be performed.

Examples: G 81 U-4.0

U-8.0

and

G 81Z-2.0

Z-4.0

G90 Turning Cycle

AG90 is the diameter cutting cycle.

It is the equivalent of

M98 Subprogram CallM98 causes another program to be executed.

The "P" value specifies the program number and the number of times to execute it.

The rightmost 4 digits are the program number.

The digits to the left are the number of repetitions.

There can be up to 999 repetitions, if the value is omitted it is called once.

Example: M98 P12 and M98 P10012 both execute CNC program 12 once.

M99 Subprogram Exit

Returns control to the program that called the current program.

If a " P" value is specified then execution begins form the block with the same "N" number, otherwise it is form the block after the subprogram call.

If an M99 is specified in the main program then the execution is from the start of the program. This is called looping (or) nesting of two programs.

Example: M99

Returns to the block following the call.

M99 P10

Returns to the block with "N" value 10.

5. What is the use of multiple boring cycle?CNC MILLING

DESCRIPTION FOR M CODES

M00 Program Stop

M00 waits for EOB to be pressed.

M02 End of Program

M02 halt program execution

The spindle is turned off and the tool moves to the most positive position on the Z axis

M03 Start Spindle

An M03 instruction starts forward spindle motion. It requires a speed within the range 100 to 3000 RPM

Example : M03 S2200

The spindle should be switched on before any movement below the component surface.

M04 Reverse Spindle

An M04 instruction starts reverse spindle motion, it requires a speed within the range 100 to 3000 rpm.

Example : M04 S2200

The spindle should be switched on before any movement below the component surface.

M05 Stop Spindle

An M05 instruction stops spindle rotation.

It is good programming practice to issue an M05 before a tool change, and at the end of a program, However this will be done automatically should you omit this instruction

M06 Change Tool

The M06 instruction causes the Fanuc to change to a different tool. The tool changing operation should be done in the home position only.

Example: M06 T1

You can get tool length and diameter at the start of the program using the TOOLDEF directive. Only for the simulation practice.

M08 Coolant On

M08 turns the coolant on.

M09 Coolant Off

M09 turns the coolant off.

M10/11 Work Clamp Open/Close

M10 opens the work clamp

M11 closes the work clamp.

M13 Coolant Spindle Fwd

M13 turns the coolant on and starts forward spindle motion.

Example : M13 S1000

M14 Coolant Spindle Rev

M13 turns the coolant on and starts reverse spindle motion.

Example: M14 S1000

M19 Orientate Spindle

M19 orientates the spindle

M20 /21 ATC Arm In / Out

M20 moves the ATC arm in.

M21 moves the ATC arm out.

M22 / 23 ATC Arm Down / Up

M22 moves the ATC arm down.

M23 moves the ATC arm up.

M24/25 ATC Arm Clamping

M24 activates the ATC drawbar. [Tool release]

M25 releases the ATC drawbar. [Tool pick up]

M27 Reset Carousel

M27 can be used in the control panel.

The current carousel position is treated as position one.

Example : At the time of tool changing operation the screen will display the current station number which is engaged for particular operation.

M32/33 Turret Indexing

M32 Clockwise rotation of turret

M33 Counter clockwise rotation of the turret

M38/39 Door Open /Close

M38 opens the door

M39 closes the door

Input/ Output Commands for FMS

M62/65 Auxiliary output 1/2 on

M62 Sets Auxiliary output 1 on

M65 Sets Auxiliary output 2 onM64/63 Auxiliary output 1/2 offM64 Sets Auxiliary output 1 off

M63 Sets Auxiliary output 2 off

COMMANDS DESCRIPTION

These commands are available in the machine side

The Robot inputs can be switched on by sending the output signal from machine side to Robot side as a input signal.

M76//67 Waiting for Auxiliary input 1/2 on

M76 waiting for Auxiliary input 1 on

M67 waiting for Auxiliary input 2 on

NOTE: M76/67/66/77

These M Codes are available in the machine side. The machine side inputs can be switched on by transferring the output signal from Robot side to machine aide as a input signal.

The machine inputs can be switched on by transferring the high signal which comes from the Robot side. The machine inputs can be switched off by transferring the low signal which comes from the Robot side .

M70 X Mirror On

M70 sets X axis mirroring about the current X axis position.

M71 Y Mirror On

M71 sets Y axis mirroring about the current Y axis position.

M76/77 Wait for Auxiliary 1/2 on

M76 waits for auxiliary input 1 t become off

M77 waits for auxiliary input 2 to become off.

M80 X Mirror Off

M80 disables X axis mirroring

M81 Y Mirror Off

M81 disables Y axis mirroring

M98 Subprogram Call

M98 causes another program to be executed. The "P" value specifies the program number and the number of times to execute it.

The right most 4 digits are the program number.

The digits to the left are the number of repetitions.

There can be up to 999 repetitions, if the value is omitted it is called once.

Examples: M98 P12

and M98 P10012

both execute CNC program 12 once.

M99 Subprogram Exit

Returns control to the program that called the current program.

If a "P" value is specified then execution begins form the block with the same "N" number, otherwise it is form the block after the subprogram call.

If an M99 is specified in the main program then the execution is form the start of the program. This is called looping (or) nesting of one or more programs

Example: M99

Returns to the block following the call.

M99 P10

Returns to the block with "N" value 10.

DESCRIPTION OF G CODES

G00 Rapid Traverse or fast Traverse

AG00 causes the tool to move to the specified position at the maximum speed.

Example: G00 X20 Y30 Z1

Here the tool is moved to X 20mm, Y 30mm, and Z 1mm.

G01 Linear Interpolation or Slow Traverse

AG01 causes linear motion to the given position.

Example : G01 X20 Y30 Z -1 F180

Here the tool is moved to X 20 mm, Y 30mm, and Z - 1mm at a feed rate of 180 mm per minute.

G02 Clockwise Circular Interpolation

Arcs can be specified by either radius or by centre.

If a positive radius is specified then the shorter arc is cut. If it is negative then the longer arc is cut.

Example: G02 X30 Y20 R15 F80

In this example the tool is moved to X30mm and Y 20mm. The arc has a radius of 15mm.

"I" and "J" specify the arc start. If the value is 0 then it need not be specified.

Example: G02 X30 Y20 I15 J0 F80 G03 Counter - Clockwise Circular Interpolation

G03 causes counter - clockwise circular motion.

Arcs can be specified by either radius or arc centre. If a positive radius is specified then the shorter arc is cut. If it is negative then the longer arc is cut.

Example: G03 X30 Y20 R15 F80

In this example the tool is moved to X 30 mm and Y 20mm. The arc has a radius of 15mm"I" and "J" specify the arc centre relative to the arc start. If the value is 0 then it need not be specified.

Example: G03 X30 Y20 I15 J0 F80

G04 Dwell

A Dwell of up to 500 seconds can be programmed.

Example: G04 X10

This causes a delay in machining of 10 seconds. This can be used for drilling cycles.

G20 Imperial Units

All future instruction parameters will be taken as imperial values. That is, they will specify inches.

G21 Metric Units

All future instruction parameters will be taken as metric values. That is, they will specify millimeters. By default metric units will be taken for part programming.

G28 Goto Reference Point

A G28 causes a fast traverse to the specified position and then to the machine datum.

Example: G28 X84.0 Y80.0 Z5.0

G40 Cancel Tool Radius Compensation

G40 switches off any tool radius compensation activated by a G41 or G42.G41 Left Hand Radius Compensation

G41 causes future movement to take place to the left of the programmed path.

The offset used is equal to the radius of the current tool.

G42 Right Hand Radius Compensation

G42 causes future movement to take place to the right of the programmed path

The offset used is equal to the radius of the current tool.

G73 Past Peck Drilling Cycle

Example: G73 X1.0 Y1.0 Z-5.0 Q0.3 R1.0 K1 P500 F30

"X" and "Y" are the next position to drill at.

"Z" is the base of the hole

"Q" is the cut in value

"R" is the R point level

"K" is the number of repetitions it defaults to 1

"p" Dwelling time

"F" Feed rate

G74 Counter Tapping Cycle

Example: G74 X1.0 Y1.0 Z-6.0 R1.0 P750 F30

"X" and "Y" are the next position to drill at



"P" is 1000 times the delay in seconds

"K" is the number of repetitions it defaults to 1.

"F" Feed rate

G84 Tapping Cycle

Example : G84 X1.0 Y1.0 Z-6.0 R1.0 P750 K1 F30






"F" Feed rate

G85 Boring Cycle

Example: G85 X1.0 Y1.0 Z-6.0 K1 F30




"F" Feed rate

G86 Boring Cycle

Example: G86 X1.0 Y1.0 Z-6.0 K1 F30




"F" Feed rate

G87 Back Boring Cycle

Example: G87 X1.0 Y1.0 Z-6.0 P300 Q0.7 K1 F30



"Q" is the shift value

"R" is the number of repetitions it defaults to 1

"F" Feed rateG89 Boring CycleExample: G89 X1.0 Y1.0 Z-6.0 P1000 K1 F30





"F" Feed rate

G90 Absolute Movement

All future movement will be absolute until over - ridden by a G91 instruction. This is the default setting.

Example: G90

G01 X30 Y0

The position becomes X30 Y0

G91 Incremental Movement

All future movement will be incremental until over - ridden by a G90 instruction.

Example: G90

G01 X15

G91

G01 X2

The position become X17

G92 Set Datum

G92 sets the datum relative to the current position.

Example: G00 X30.0 Y40.0

G92 X0.0 Y0.0

Makes the position that was X30 Y40 become X0 Y0

G94 Per Minute Feed

The "F" value specifies the feed rate in millimeters, or inches, per minute.

G95 Per Revolution Feed

The "F" value is the ratio of feed rate to spindle speed. The feed rate is changed whenever the spindle changes.

Example: G95 S1200

G01 X10.0 P0.3

This sets the feed rate to 360, (1200*0.3)

G98 Initial Level Return

G98 sets the initial level return mode for drilling cycles.

G99 R Point Return

G99 sets the R point return mode for drilling cycles.
