G0- Rapid

G00- (I hope you already know this one!)

A new feature is also available. G0Z0,I.1 . This is in-position

check. This might be used to save time not needing accuracy during

rapid motion. If you use 'G0 Z' without ',I' then rapid is back

to normal.

You can also use I J K giving the center of the arc from the

position

you start at before the G2. I=X J=Y K=Z G2X.5W.01K.01I0

Circle Example...

When milling with or without cutter comp(G41/G42), the feed rate

given is not true. To get a proper feed rate you have to

calculate

using the radius desired and the tool radius. Cutting outside

corners are different then inside pockets. Use this formula...

Outside cutting:

DesiredFeed=10 IPM CutRadius=.25 ToolRadius=.125

Feed=DesiredFeed * ((CutRadius+ToolRadius)/CutRadius)

Feed= 10 * ( .375 / .25)

Feed=10 * 1.5

Feed=15

Also Helical Interpolation: Same as Circular interpolation

but while 2 axis are circular interpolating, another axis

moves linear. This is mainly used for thread milling, having

to arc Z-Y around the thread in circles and move X down in the

part.

G9- Exact stop mode

G09- G9 will make the axis stop after the program line. Used when no

radius is allowed on an outside or inside corner.

G1 G9 Z1. F.002

G10- Offset input from RS232C or program

The way Mitsubishi worked this one is much better than Fanuc. If you

choose I/O OUTPUT function and download "OFFSET" this

will send a bunch of G10 and G11 commands to a file. This is all the

offsets in a special code. To send it back to the machine later just

pick I/O "tool data" and INPUT, and the offsets are loaded into the

machine from the RS232, no need to run a program.

G10 L11 P1 X.001 Z.005 R.002

(P=offset number)

You can also use G10 to set parameters. Please see the Mitsubishi

manual for more details.

G12.1- Converts C axis degrees and X axis movement to work like

a milling machine. Program X-Y axis and the control converts all

the

commands to degrees automatically. X and Y are programmed in radius

values and zero is at the center of the part, like a milling

machine.

Tool nose rad comp is also needed to use G12.1 correctly. Thinking

about the direction for G2/G3 and G41/G42 is backwards! You have to

imagine you are back behind the guide bushing looking to the

cutter.

If you can't do this, then just do everything opposite!

There are some new options while calling G12.1. We used to have to

change parameters to use G12.1 #1125 Mill_AX and #1126 MillC ,

now

we can set these while calling G12.1 . See also G16 below.

G12.1 (no arguments uses C commands same as G12.1 D1 E=C)

G12.1 D0 E=C

D0 -You can use "C" or "Y" as the virtual axis while in G12.1

The manual suggests using "D1" to use "C" but I don't

agree.

If in G17 X-Y plane, then I suggest you use "D0" to use Y".

Your choice, it makes no difference which you use! If D is

not on the G12.1 line then "C" is default.

Always have "D" first on the G12.1 line!

E=C -This will set the axis number of the system to use as the

polar axis. This depends if you are using the gang plate in

$1 or the U121B option in $2 or $3. Setting E=C will set

the

proper axis automatically. If you don't use E=C on the line

then

$1 C axis is default. For safety, always use E=C

G16- Plane select Y-Z cylindrical machining. To use this plane you need

the

option of G12.1 milling interpolation. G16 is used to convert polar

C axis degrees to linear Y when machining "J" slots or cylindrical

cams. Most of these part prints are dimensioned with linear and

radial

values, not degrees. Also the prints usually show the part cut and

spread flat. Radii are hard to program and adjust without G16 and

tool

nose radius comp. G41-G42. Programming would be linear "Z Y".

The polar "C" axis is converted to a linear "Y" axis. Another use of

G16

is to chamfer a cross hole equaly all the way around the hole.

G16C.15

C= Position of X axis to calculate from if the actual cutting

position is different. This is in radial value. C.15 = X.3

G17- Plane select X-Y -When viewing this plane from the guide bushing you

need to be looking from the spindle to the GB and this is difficult.

So

swap your G2/G3 and G41/G42.

G18- Plane select X-Z normally used. G18 is when power on. View looking

at

The GB

G19- Plane select Y-Z. View looking down from milling tools at the GB.

G28- Automatic reference return. Usually use the incremental command for

each axis. "G28 U0 W0". You probably won't use G28

G32- Threading- G32 locks the feed-rate override at 100% and turns off

the single block mode. Then G32 looks to find an exact spot on the

spindle to start feeding. G32 is canceled by a G00 command. It's

uses are for multiple angle threads (bone screws, worm gears) or

we commonly use G32 when we tap a part with the main spindle, or the

PO spindle. G32 won't work on the secondary spindles because there

is no encoder on S3 or S4.

If you are cutting a special OD thread always start G32 on a Z move.

If you start G32 on an X move, the spindle zero will pick up in a

different Z position each time. Position "X" first then "G32 Z"

G32 can also adjust the spindle zero for double start threads.

G32 Q180. =180 deg from spindle zero.

G34-Variable lead threading. This command is the same as G32 but

has the "K" value for the amount of pitch change per revolution. See

G32-

G34 X Z F.03 K.05

X= Position to go to in X

Z= Position to go to in Z

F= Feed rate in IPR

K.05= Amount of change in pitch per revolution. Can be growing pitch

if plus value or reducing pitch if minus value. First rev will

be F.03

2nd rev is (.03+.05) 3rd rev is (.08+.05) and so on.

G40- Tool nose radius compensation CANCEL. Turns off G41 or G42

G41- Tool nose radius compensation LEFT. Usually used when front

turning on Cincom machines in a Z positive direction. There are 8

sections of the radius to be used.

1= Boring

3= Back turning

4= Front turn (see manual for details)

8= Profile

0= Endmill

G42- Tool nose radius compensation RIGHT. Not used as often. G42

could be used when traveling in a Z negative direction. See G41

G43- Feed per revolution in $2 on S1. IPR and CSF is read off of the main

spindle. This is used when in G620 and programming from $2 but

feeding

IPR to S1. The default is G43 so feeding in $1 and $2 is IPR off the

main spindle.

G44- Feed per revolution in $2 on S2. IPR and CSF is read off of the sub

spindle. Used to single point thread with the pick-off spindle, tap,

or any IPR feeding needed to be done from the S2 spindle. This code

is

unique to each side $1 and $2. Probably you will only use G44 in $2

because you normally don't need to feed from S2 on the front side

program unless using G600 and TxxxxK2.

G50- Coordinate system setting. Used to either set the position of an

axis

absolutely to a known value, or to move the position of an axis

incrementally over a specified amount. The axis doesn't move but the

position screen changes. Also spindle speed clamp.

G50 Z0 makes current position of Z axis = 0 but no movement of Z

L programs only use one "G50Z" in each program at the

beginning to establish part zero.

G50Z.401 when a left hand cutoff is used. .5-.094-.005

G50 W-.59 shifts the coordinate system over for temporary use then

it

would be shifted back by G50 W.59 after tool is

G53 Z3. ,F80.

The ",F" is a new feature that enables a feed rate command for G53.

If used the ",F" is a one shot feed rate cammand, not changing

modal "F".

G65- Calling a macro program. Same as M98 but we pass variables to a

macro

sub-program. You would have to learn macro's to make macro programs

but I have a macro for Peck Drilling you might want to use. Instead

of the G83 option.

G76- Canned threading cycle

G76 P010060 Q.002 R.0005 (first G76 sets parameters for

threading)

G76 X Z P Q F R (cuts the thread)

The first G76 isn't needed but is recommended.

- G76 P Q R

P010060 sets 3 things

- first 2 digits is the amount of finish passes - 01

- second 2 digits is % of the lead or pullout exiting the thread-

00

00 = almost no angle at pullout and 99 = 9.9 leads away start out

- third 2 digits are the angle of infeed - 60

0,29,30,55,60,80 are usable (0-90 is ok)

The actual cutting infeed =(value/2)-.5 so a value of 60 = 29.5

infeed

Q.005 sets the minimum cut amount during threading

R.0005 sets the cut amount of the last pass

The second G76 cuts the thread.

-G76 X.1876 Z.3 P.0302 Q.01 F.05 (R-.002) FOR 1/4-20

X.1876 =Minor Dia. of thread

Z.3 or (W) =The ending Z of the thread

P.0302 =Height of thread in radius (Maj-Min)/2

Q.01 =Amount of the first cut. All the rest of the cuts are

calculated.

F.05 =Feed-rate 20 TPI 1/20=.05

R = R is optional for tapered threading. R is the amount of

difference in X from start to finish in Z. When cutting threads

moving Z and X in a positive direction R is a negative value.

G80-Cancel G8? series codes. If only using G83 we don't need G80

G83-Peck drilling cycle. There are (2) parameters related to G83.

Control Param #8125 "G83 Rapid" if ON then the pecks do NOT come out

of

the hole, they only back up the amount of Setup1 Param "G83 Retract"

to break the chip and then start feeding again.

Setup1 Param "G83 Retract .02" is the amount to rapid back into the

hole from the last peck for clearance.

I suggest...

Setup1 Param "G83 Retract"=.02

Control Param #8125 "G83 Rapid"=OFF

Example-

G0 Z-.05 T22

G83 Z1. F.001 R.03 Q.04 P0

Z1. =Z position of the bottom of the hole

F.001 =Feed in IPR or IPM

R.03 =Rapid from current Z position the R amount incrementally.

If starting at Z-.05 and R=.03 then the Z axis rapidly

positions to "Z-.02" and after every peck Z retracts to

the same position "Z-.02". If you use "R-.03" it is the same

as "R.03". Leave R out to start from current Z position.

Q.04 =Peck amount

P0 =Dwell amount at the bottom of the hole. You can just leave

P off the command line if you want

K4 =If face off center drilling use K for the amount of holes

Just leave K off the command if only one.

H90. =If you have C axis option and using K

,F30= This was added! Now you can change the rapid moves to a feed

if desired.

G814-Same as G114.1 but you don't need all the codes on the

Citizen added this macro just to make it easier to use spindle

sync. See G114.1 and G113. You may save time by not using G814.

G814 even with no 'R' argument will internaly use 'R0' and this

will force a phase shift for spindle sync, needing also to use M77.

L6= Number of flats to be cut on the part.

R15. = Phase shifting amount in degrees.(only on 1:1 ratio

spindles)

G114.3-(option) Gear hobbing command. With a special holder this command

will

time the cutter(S3) and spindle(S1C1) to constantly hold position

so all we do is feed across the part as if we were turning and a

gear shape is cut. A "C" axis is also needed! Use G113 to cancel.

G114.3 H3 D-9 E1 L18 (P0) (Q1.)

H3 = Master spindle or S3(gang live tool)

D-9= Slave spindle or 9= Caxis -9 = reverse

E1 = Rotation rate. Always set to one. Not sure exactly why!

L18= Number of gear teeth to be on the part.

P0 = Helix angle -89.000 to 89.000 for helical gears. Leave off

or set to P0 for spur(straight) gears.

Q1.= Gear module. For helical gears only.

G115- Start point queuing (Type 1)

or Queuing during an axis movement (Type 1)

The programming system that G115 is in waits until the

other system reaches a specified axis position then continues.

See G116 below.

Example... getting P.O. spindle over the part while still turning.

the desired position and finish moving at the queuing point. G149 is

used in "M32 X.1" and will have Z2 and the catcher basket under the

part when X=.1 . Z2 won't start coming in at X.1 but will start

sooner to be there when X gets to .1 . You also need to add special

line lables to mark the lines to end at. "BNxxx"

G156- Mirroring two axis. Used automatically in G821 to lock Y1 to X2 so

the drills can't hit the turning tools while using T2?00 stations.

You won't normally use G156. If you don't command the other axis,

it

just follows.

G156 Y1=X2 ON

G156 Y1 OFF

G156- Superimpose one axis onto another. G811/G650/G620 uses G156 to make

the Z2 axis follow Z1. You normally won't need G156. If you command

the other axis, it follows but also move simultaniously.

See also -G620/G650

G156 Z2=Z1 turns on Also queue $1 and $2 before G156

G156 Z2 turns back off

G160- Axis torque sensing command. (normally not used) This is used

internally by

Citizen for the auto collet adjusting and auto guide bushing

adjustment.

Possible uses could be to check the Z2 torque while positioning

over the

part when picking off. If the turning tool has failed and the size

is big,

the collet could jam on to the part! G160 will feed to the desired

position at the commanded feed but if the torque is reached the

axis will

stop short of the commanded position. We can then use macro to

determine

where it stopped. G160 is a one shot code and after G160 is done or

if the

torque was met, then 100% of torque is set back to the commanded

axis. I

tested and I used G160 with a shank of a tool and checked the

turned size

of a part and had .0003" repeating! Maybe this is not good for all

jobs

but could be used as part of an auto offset macro!

G160 will not work on a superimposed axis. So if you have a CAV, A7

is

superimposed on Z1 and G160 can not be used on Z1. Instead just use

Z2

for the motion if needed.(no problem)

G173-Inclined rotation setting. Used with helical interpolation

to perform angled milling or angled thread milling. It will also

let you program angle peck drilling easier. While in G173 mode, all

axis are radius designation programming, like a milling machine.

After the G173 command the axis position remains the same position

as it was before the command but X becomes radial. Keep this in mind

while programming.

Offsetting: The Offset has to be commanded before G173 and this

makes

it more difficult to send a drill in .01 as you need to offset both

axis to the angle to get the movment you desire. Using macro, we

have

a way to utilize the offset data, and we G50 for the offset, see

below

G173 Y0 Z0 D5. or G173 X0 Z.5 D5.

G173 no arguments cancels the G173 command.

Y0 = Center of rotation position of Y

Z0 = Center of rotation position of Z

X0 = Center of rotation position of X

D5.= Angle of rotation.

Remember to use G173 again with no arguments to cancel.

G600's-The G600's commands are Citizen's way of makeing a very complex

multi

axis machine, very easy to program. These G600's commands are

called

mode selections. G600,G610,G620,G630,G650,G660. All of these

commands

select each axis in each of the three systems. G620,G650 enable

superimposition. This is the ability of one axis to follow another

axis

but still be fully programmable. For example we can peck drill and

turn

simultaniously at different feed rates. Because all the G600's

mode are

working with all the axis, all systems are queued with each other

by

commanding the code in all systems for the mode change. There are

also

different arguments possible for each command that can change the

axis

movements as desired. See each code and it's arguments below...

G600- Cancel all G6xx commands. Also G600 is the default mode before the

program starts and after the G999 command at the end of the

program.

G600 will queue with both lines $1-$2 then X1-Z1-Y1-C1 are now

controlled from $1,and X2-Z2-C2 is controlled from $2.

Also when in MDI, Mode G600 is in affect.

$1 $2

G600 G600

G600 command options...

$1 G600 (no arguments are allowed in $1)

$2 G600 (No arguments means Z2 moves away to Z2 home position)

G600W0 (W0 means leave Z2 at the current position)

G610- Machining mode change to use the three drill stations T21-T23 in

the

$1 programming line. G610 will queue with lines $1-$2. All the

programming

is done in $1 and $2 must wait on G600. This replaces the L51620's

G821

command because G610 works deeply with the first T2x00 call to move

Z2 in while

changing the mode. This saves 1 second per use! X2-Z1-C1 are now

used in $1.

Because M140 is not used, you can use 'T2200 S-1.' on the first

T2x00 to change

the position of Z2 when brining in the drills.

Example...

$1 $2

G610 G610($1 takes control of

G600 G600($2 takes control of

G620- Machining mode change to superimpose Z2 onto Z1 . G620 will queue

with lines $1-$2 then make Z2 follow Z1 but Z2 can also be

programmed

independently. Example if we are drilling while turning.

Note- Any shift, "G50W-.125", on Z1 must be canceled, "G50W.125",

before

G620 or G620 won't find the face of the part!

G600 G600

G50Z0(safety resets Z2 position)

G630- Front Back paralle machining mode. Basicly G630 is the same as

G600.

But G630 will start moving X2Z2 before X1Y1 are finished. During

the

next T-code in system1 X2Z2 move saving time. This saves about .2

seconds from using G600! G630 will queue with both lines $1-$2 then

X1-Z1-Y1-C1 are now controlled from $1,and X2-Z2-C2 are controlled

from $2. You can not command Z in $2 until after T3x00.

G650- Machining mode change to superimpose Z2 on to Z1. G650 will queue

with both lines $1-$2 then make Z2 follow Z1 but Z2 can also be

programmed independently. Example -when we pick up a part and

chamfer

it while we have the back spindle collet closed on the part. Also

if we are using Z2 as a work support.

Note- Any shift, "G50W-.125", on Z1 must be canceled, "G50W.125",

G999- Finish last part. Finishes the part in the P.O. spindle if you are

running in SINGLE CYCLE MODE. While the machine is running usually

the work on the P.O. spindle is completed while the front of the

part

is also working. When the counter is full or the bar stock is empty

or

if we are in ONE CYCLE MODE then we can finish the part by using

G999

and N999 in our program. If in regular CONTINUOUS CYCLE MODE then

the

CNC statements between G999 and N999 are skipped but if in ONE

CYCLE

MODE or the counter is full or there are other operator alarms then

the CNC statements between G999 and N999 are read and performed.

G999

time you want to turn off this function then turn off soft key in

auto

skipped no mater what MODE your in. Mode G700 is in affect at the

first.

This possibly saves time but is DANGEROUS.

BE CAREFUL!

T0200 H.5 -H.5 Rapids the current tool to stock size +.5

then

indexes to the new tool. Used to alter the

position point

for the one time index.

T0700 K2 -After the Tool is called, the Z2 axis is the

commanded

Z axis. Also the C2 axis is called up.

X1,Y1,Z2,C2 are

commanded from $1. The next T__00 call changes it

back.

T0700 E90. -While the Tool is called, the C1 axis is

positioned at

the same time to the E value.

T1200R1 -R1 is used to call the 2nd tool of a dbl holder

on the

GSE3010 block. R1 is the outside tool.

T1200R1 A1 -A1 A5 will allow the tool hidden zero data to be

chosen

when using G660 both ends drilling. A1 will use

the front

tool zero data and the back tool will be off. A5

will use

the back drill zero data and the front drill will

be off.

If no A is used or A0 then the zero data from

front and back

are split to make both off a little.

T400 M1 -If M1 is used it will not use the highest tool

set clearance.

This might be used to save cycle time but be

careful!

After T5x00 the axis programmed are X1-Y1-Z2-C2

T5200 X.2 Q1 -Q1 will keep Z2 axis where it is

for the tool change. If ommitted Z2 moves back

5mm or .1968"

first, then indexes the tool.

T5200 X.2 Q3 -Q3 will force Z2 axis to go home for the tool

change.

If ommitted Z2 moves back 5mm or .1968" first,

then indexes

the tool.

T5200R1 -R1 is used to call the 2nd tool of a dbl holder

on the

GSE3010 block. R1 is the outside tool.

T5200 W-.2 -If W is on the command then Z2 moves to W amount

from where

it was then calls the next tool. If no W then it

moves back

5mm or .1968"

T5100 Z.5 -If Z is on the command then Z2 moves to Z2

machine pos not

the part position. If no Z then it moves back

5mm or .1968"

T5200 X.5 -Use X to change the position of the X axis while

indexing.

T5200 E90. -While the Tool is called, the C2 axis is

positioned at

the same time to the E value.

T2300 Z-.05 Q1 -If in G620, Q1 will keep Z2 axis where it is


first.

T2300 W-.1 -If in G620 mode and W is NOT on the line Z2 goes

to home position first then indexes and comes

back

in to work. If W is on the line, Z2 goes to W

amount incrementaly.

T2100 S-1. -If in G610 mode and you have a shifted tool (the

tool

is set diff. from normal tool set zero) it may

hit when

using G610 and T2100 high speed positioning

function.

Use the S argument to change the position of Z2

when calling

up this tool only used on the first T2x00 tool

after G610.
