The coordinates system is dened in the plane created by the crossing of one line parallel

to longitudinal movement (Z), with a line parallel to transversal movement (X).

All movement of tool end is described in this plan XZ, in relation to a pre-dened reference

(X0, Z0). Please remember X is always diameter measuring.

OBSERVATION: The positive or negative signal introduced in the dimension to be

programmed is given by quadrant where the tool is located.

1 51.1- ABSOLUTE COORDINATE SYSTEM

In this system, the reference is established in function of the part to be made, that is,we can establish it at any point of the space to make programming easier. This process isnamed “WORK PIECE REFERENCE”.

As we saw, the system reference was xed as the points X0, Z0. X0 point is denedby the Center line of the spindle. The Z0 point is dened by any line perpendicular to Centerline of the spindle.

During programming, usually the reference (X0, Z0) is pre-dened in the part bottom(jaw support) or at the part face, according illustration below:

1 51.2- INCREMENTAL COORDINATE SYSTEM

The origin of this system is established for each tool movement. After any displacement, a new reference will occur, that is, for any point reached by the

tool, the coordinates reference will pass to be the reached point.

All measurings are done between the distance to be displaced.If the tool displaces from a point A to B (any two points), the coordinates to be programmed

will be distances between two points, measurements (designed) in X and Z.Please observe the Point A is displacement reference for point B, and B will be the

reference for a displacement up to point C, and so on.

1 52.2.2 - Code: O

Application: To identify programs

Each program or sub-program at command memory is identied by a single number

“O” composed by up to 4 digits, it can oat from 0000 to 9999.

OBSERVATION: All programs in the range 8000 to 9999 are protected, so the user

has Access only to Edit programs in the range 0000 to 7999.

2.2.3 - Code: Bar (/)

Application: To inhibit blocks running.

We use the Function Bar (/) when it is necessary to inhibit blocks running in program,not changing programming.

If the character “/” is typed in front of some blocks, they will be ignored by command,

since the operator has been selected the option BLOCK DELETE in command panel.If the option BLOCK DELETE is not selected, the command will execute normally the

blocks, including thos with the character “/”. 2.2.4 - Code: F

Application: to determine infeed speed

The infeed speed is an importante data for machining, and it is obtained consideringmaterial, tool and operation to be done.

Usually, for CNC lathes, we dene infeed using mm/revolution (function G95), but it is

also used as mm/min (function G94).

2.2.5 - Code: T

Application: to select tool

The function T is used to select tool, it tells the machine its zeroing (PRE-SET), insertradius, cutting direction and correctors.

The code “T” shall be followed for at most four digits in its programming, being thereare two ways to dene the application of these digits, depending on the value inserted in

parameter 50021.

a) Parameter 5002.1 = 0T 0 1 0 1 Tool’s geometry and wear

Turret position (only)

b) Parameter 5002.1 = 1

4.1 - FUNCTION: G00

Application: Quick positioning (approach and return).

The shafts moves to the programmed target using the most infeed speed available inthe machine:

Syntaxis:G0 X__ Z__ Where:

X = Coordinate to be reached (values in diameter)

Z = Coordinate to be reached

The function G0 is Modal, and it cancells functions G1, G2, G3.

OBSERVATION: At GL line, the quick displacement speed is 24m/min, in “X” and

30m/min in “Z”, and it is processed in rst at 45° up to one of the programmed targets “X”

or “Z”, and after this to displace in a single shaft to the wanted nal point.

Both G2 or F3 executes machining operations of pre-dened arcs by a proper andsimultaneous movement of the shafts.

Syntaxis:G2/G3 X__ Z__ R__ (F__)or G2/G3 X__ Z__ I__ K__ (F__)

Where:

X ( U ) = nal position of the arc

Z ( W ) = nal position of the arc

I = Incremental distance at “X” between start point of the arc and its center (in radius).

K = incremental distance at “Z” between start point of the arc and its Center

OBSERVATION: At the programming of na arc, we shall observe the following rules:

• The start point of the arc is the start position of the tool.

•The circular interpolation G02 or G03 (clockwise / counterclockwise) direction is

programmed.

•Together the interpolation direction, we program the coordinates of the nal point

of the arc with X and Y.

•Together the arc direction and nal coordinates, the R function (radius value) or

so, functions I and K (coordinates fo the Center of the arc) are programmed.

1 513.5 – WORK REFERENCE (G54 A G59)

Work Reference, also known as Work Piece Reference, corresponds to the point whichserves as reference for absolute coordinates system, that is, it is the part point referencedas “X0” and “Z0”.

In some cases, more than one work reference is used in a same program, with thepurpose to make easier the programming of some parts. Example: in case of programmingthe machining of two sides of a part in a same program, it is recommended to use two workpiece reference, in order to the programmer must not be worried with somes elements, asmetal excess at both sides of material, different jaw backs, etc.

NOTE: At the machines “GL Line”, up to six zero-part can be referenced, which shall

be done manually during machine’s preparation process. They are: G54, G55, G56, G57,

G58 and G59.

EXAMPLE:

G54 (FIRST SIDE) G55 (SECOND SIDE)

The values of family G54 shall be typed in the Page “OFFSET SETTING” by the softkey

1 514 - MISCELLANEOUS OR AUXILIARY FUNCTIONS

The auxiliary functions comprise the machine resources not covered by the previousfunctions.

NOTES:- Machines from “Line E” shall be set in many modes (with/without counterpoint,

with/without second spindle, with/without tool actuated, etc.) and so, not all functionsdescribed below are enabled in all machines.

- Functions with “INSTANT REPLY” shall be set carefully, because the machinenot waits Ladder conrmation to continue program running.

FUNCTION: M00Application: program stop.

This code causes immediate stoppage of program running, including cut coolant andspindle.

FUNCTION: M01Application: optional stop of the program.

This function interrupts the program running only if the button “OPTIONAL STOP”, locatedat the machine operation panel, is pressed. Thus, function M01 will be equivalent to functionM00, but, if the button is not active, the command will ignore function M01, keeping the normalprogram running.

When the stop occurs by this code, the button “CYCLE START” shall be pressed tocontinue program running.

FUNCTION: M02Application: end of the program, with no return to beginning.

This function is used to indicate the end of the program existing in the command memory,and it is also used when working with tapes joined in “tie” shape.

FUNCTION: M03

Application: turns on left spindle in clockwise direction.

This function turns the spindle clockwise, adopting as reference for the slewing directionthe rear position of the chuck.,

1 516 - CALCULATIONS

16.1 - CUTTING SPEED (VC)

Depending on material to be machined, cutting speed is an important and necessary data.

Cutting speed is a quantity directly proportional to diameter and revolution of spindle,given by formula:

VC = Ø

P x 3,14 x N

1000Where:

VC = Cutting speed (m/min)Ø

P = Part diameter (mm)

N = Revolution of spindle (rpm)

16.2 - REVOLUTION (N)

At the determination of cutting speed for a determined tool do it at machining, revolutionis given by formula:

N = VC X 100

3,14 x Ø

16.3 - CUTTING POWER (NC)

In order to avoid some problems during machining, as motor overload and so stop ofspindle during operation, it is necessary to make a previous calculation of Power to be used,which is given by formula:

NC = KS X FN X AP X VC

4500 X n

1 51- DEFINITION OF AXES

1.1 - AXES X / Z

They are the axes which make the machine turret set; they are responsible to move thetool, in order to develop a programmed prole.

Axes “X” and “Z”, as sawn in previous chapters, usually are used in turning operations,where they represent the diameter setting (axis X) and length (axis Z) to be machined.However, since now, using some specic cycles and resources, these axes shall help milling

operations, axial and radial drilling, among other. Axis “Y” will be very useful in radial milling operations, where we want to machine some

detail out of the geometric center of the part, and axial operations, as well. When working inturning operations, this axis shall be positioned in the part center (position Y0), it is mandatory.

1.2 - SPINDLES

We will also consider two settings to work with spindles, where they shall be used as

rotational axes (spindles) for turning operations, or be set as work axes (axis “C”), which willhelp in operations with driven tools.

Explanation

The function POLAR COORDINATES create a virtual plan with axis X and C’, wherevalues are given in millimeter or inches. The setting mode for axis X shall have the same usualsetting criterion, that is, value given in radius or diameter, according dened in parameter

1006 bit3. The virtual axis C’ simulates axis Y, as if plan XC is XY. thus, we can work with

milling operations as in a Machining Center. Although the virtual axis is dened as C’, only C shall be set for the referred axis.

During the running of programming blocks, the command converts linear dimensionsof virtual axis C’ in rotational movements for true axis C.

1.3.1 - FUNCTION M85 / M86.

Application: High torque brake and low torque brake

When axis C is activated, the machine transforms the chuck in more one axis to be set.However, in rst it shall have as rigidity only the power of the electric engine.

In order to perform milling or drilling operations, we shall activate a brake (M85 or M86),to avoid that the machine lose the chuck guide during a machining with tools driven.

Example:

M85= High torque brake. Locks totally the chuck, Not allowing any movement (it canbe cancelled with function M86 or M5.

M86= Low torque brake. It allows moving the chuck, keeping it accurately guided.

OBSERVATION: WHEN THE HIGH TORQUE BRAKE IS ACTUATED (M85), IT IS NOT

ALLOWED MOVEMENT OF AXIS C, IT IS NECESSARY TO CANCEL THIS BRAKE WITH

FUNCTION M86, AND, IF APPLICABLE, ACTIVATE IT AGAIN AFTER AXIS INDEXING.

1 54 - RADIUS OFFSET AND CIRCULAR INTERPOLATION

The Tool Tip Radius Offset is a CNC function which allows, in despite set by its TheoreticalTip, to offset geometrically the Tool Radius position on setting elements, as Tilted Line (Cone)and Arcs.

It is not necessary to activate this function when we are programming by the ToolTip Radius Center, but, in this case, for all other coordinates, the referred Radius shall beconsidered, and the position geometry of it in relation to the programming elements alreadymentioned. Thus, in order to facilitate setting, it is highly recommended the use of RadiusOffset function!

Below we have the application scheme, considering cut direction and tool position.

criterion adopted for the frontal view of the Left Spindle.

When observing the Right Spindle frontally, the direction of axis X+ also is inverted.

From this, we can conclude that the Right Spindle has no Independent Coordinate

System, that is, axes X, Z (movement via Turret) and C obey the same criterion adopted

on the Left Spindle, looking it from top and frontally (see “Considerations on AxesDenition”).

NOTE:Due to axis C for Cylindrical Interpolation is dened by parameter as parallel to axis

X, the Circular Interpolation Functions G02/G03 and Radius Offset G41/G42 become

inverted if in plant view, because axis C+ is inverted in relation to the ordinary direction of

axis C+, established for this machine. However, if in bottom view, where axis C+ points

in the same direction that X+, the referred functions (G02/G03 G41/G42) are normal.

Considering that, for axis C, it is not the tool which moves, but the Spindle, the

positive direction of the referred axis, for setting, is dened as the contrary to the physical

direction of the respective movement. Thus, for the CNC, the mentioned above occurs.

The virtual plan Z/C of Cylindrical Interpolation, according the gure above, is

1 55.6 - RADIAL DRILLING

In order to perform holes and tapping on the part radius, we can use functions G87(radial drilling) and G88 (radial tapping), which are set as follows:

G87 – RADIAL DRILLING

G87 X__ C__ (H)___Q___ (P__) (R__) F__ K__: where;

X = Final drilling positionC = drilling angleH = Angular incrementQ = Increment value (incremental / thousandth)P = Dwell time at the end of each increment (second thousandth)

R = Reference plan to start drilling (incremental)F = InfeedK = Number of repetitions (in this case, we shall replace letter “C” by letter “H”).

4.3 – COMMUNICATION BY PCMCIA PORT

The term PCMCIA means Personal Computer Memory Card International Association,

and it is an electrical and mechanical structure of a data storage system.Machines from “GL / GLM Line” have a PCMCIA port located beside vídeo, which can

be used to transfer different types of data, as: programs, machine parameters, tool correctors,etc. For the communication with this port, we can use two types of cards: PCMCIA andCompactFlash.

In case of PCMCIA card, due to it is from the same technology of the port, it can bedirectly coupled to the machine, with no tting system. CompactFlash, due to is from a different

technology, shall only be coupled by a electrical-mechanical adapter.In order to read and to Record data in these cards, it is necessary to use computers

equipped with respective drivers, which can be external or internal. Usually, at the use of

PCMCIA cards, it is used internal drivers, and for CompactFlash, external, Which is usuallyconnected to computer by USB port.

4.3.1 – RECOMMENDED HARDWARE FOR READING AND RECORDING:

a) PCMCIA card:

In order to read and to Record PCMCIA card, we recomend PC interface PCD-895A 00B1KIT PCMCIA, from Advantech. In this case, PCMCIA modules shall be homologated by FANUC, ifused in this CNC. This means that not all PCMCIA will work in CNC, mainly with FANUC platforms.

b) CompactFlash:

To read and to Record PCMCIA Card, we recommend interface eFilm Reader-12 USBPOR T CompactFlash I/II Reader from Delkin Devices, which shall be connected at the USBport of the computer.

Please observe that, if CompactFlash is used, a CompactFlash Adapter is necessary,when connected to CNC device. This procedure is necessary, due to the own CompactFlashhas not its own mechanical interface in PCMCIA standard. This adapter can be purchasedat Computer Stores, but always mention you want to purchase a PCMCIA Adapter forCompactFlash Type I.

In case of computers where USB port is not available, we can installa a USB controllermode, which is plugged at the own bus of the computer, making available the USB Port. Oncethis module is installed, we can congure PC according shown in gure above.

IMPORTANT: Due to incompatibilities between Windows and FANUC, it is necessary to

format PCMCIA or CompactFlash device at the own CNC before you use it. This procedure

shall be done one time only.

CHUCK PRESSURE

INDICATOR

In order to regulate xation pressure, we shall:

– Loose the lock-nut and turn the pressure regulation maniple, until the electronic

display reaches the pressure you want. – On the electronic display, activate the middle key (major), until the display shows

function “Lo”. This function is a minimum safety value. During the work cycle,

if the hydraulic system pressure drops to a value lower than the value set in

“Lo”, the machine will generate an alarm.

– By the two side keys, regulate the pressure value you want in function “Lo”.

– At the electronic display, press the middle key (major), until the display shows

function “Hi”. This function is a maximum safety value. During the work cycle,

if the hydraulic system pressure has overload to a value higher than the value

set in “Hi”, the machine will generate an alarm.

– By the two side keys, regulate the pressure value you want in function “Hi”.

– Wait a few seconds, until the pressure value regulated for the chuck (ACT) is

shown on the screen.
