3.2.3 Influencing the ”AUTOMATIC” operation

3.2.3.1 Influencing the program

Supplement to Standard Documentation

Note:

If dry run feedrate is active, the reciprocating movement programmed with G181 is executedwith the feed value programmed in the part program.

3.2.3.3 ”Block search”


Note:

The target position after block search is approached with the speed set in the machine data.

Reciprocating axes which are programmed with G181 are traversed at the rate programmed inthe part program.

3.2.7 ”JOG” mode


The oblique axis and/or the oblique grinding wheel can be traversed in Cartesiancoordinates or obliquely. The initial setting is Cartesian. Overstoring G05 switches the machineto oblique plunge grinding. If the machine has an oblique axis, only the oblique axis will bemoved, if the machine has an oblique grinding wheel, the infeed axis and the reference axisare moved.

Overstoring G01 deselects G05 and switches the machine back to Cartesian movement.

G01 is automatically activated after program start or program interrupt.

The spindle speed and the T, H, M, D and G functions can be determined using”OVERSTORE” (see Section 3.2.3.2 of the Operator´s Guide).

2.5 Zero offset


Different zero offsets can be programmed in channel 1 and channel 2. The active zero offsetvalue for each channel is used to calculate the actual value display.

2.9 Programmable working area limitation, G25/G26

Programming area limitation provides machine protection in the event of operating andprogramming errors. It can be specified in Cartesian coordinates or axis related.

























Machine data is used to define whether the programming area limitation is defined in

Cartesian coordinatesor axis related.

As soon as thetool leaves this limited area or is located outside this area on program start, or as soon as aposition outside the working area limitation is programmed, the path setting is terminated or atravel command is not accepted (program stop, no program start, alarm). The current followingerror is eliminated. Programmable working area limitation is active in AUTOMATIC mode withthe values in the setting data.

Programmable working area limitations are active in the machine-related

actual value system.

Two different working areas are produced depending on the way the working area limitation isdefined (Cartesian or axis related).

The working area must be within the software limit switch, the values of which the machinetool manufacturer defines machine specifically and enters in the machine data.

G25 Minimum working area limitationG26 Maximum working area limitation

Example: Working area limitation

N10 G25 X10 Z40 LFN20 G26 X250 Z200 LF

No more data are allowed in this block. G25/G26 overwrites the values in the setting data. Theworking area limitation is no longer active when -99999.999 and +99999.999 are input for theminimum value and the maximum value respectively for each axis in the setting data. Thevalues can also be altered by entering the values in the setting data directly.

2.10 Coordinate rotation


Coordinate rotation (CR) enables the workpiece coordinate system to be adapted to themachine coordinate system. A part program is then processed (i.e. the part is machined) in therotated coordinate system.

The turning centre is the point determined by the sum of the zero offsets (ZO).

The following coordinate rotations can be activated:

settable coordinate rotation G54 (A) to G57 (A) programmable coordinate rotation G58A ... and G59A ...

The sum of ”settable coordinate rotation” and ”programmable coordinate rotation” gives the”effective coordinate rotation”.

Settable coordinate rotation:

• No differentiation is made between fine and coarse settings.• The settable coordinate rotation is defined via setting data.• Value for angle of rotation ”A” is entered via the keyboard in input screen form Coordinate

Rotation.• The angle of rotation ”A” for G54 . . . G57 or for G154 . . . G157 can be entered via the

universal interface (input G254 . . . G257 is not permissible).

G54 activates the ZO entered for G54 in the setting data as well as the coordinate rotationG54A . . . entered in the setting data.

Programmable coordinate rotation:

• The coordinate rotation can be programmed with G90 (absolute dimensions) or G91 (incre-mental dimensions).

• The value for the angle of rotation is programmed in address ”A . . .”.

Influencing by programming

• G53 or @706: Coordinate rotation and zero offset are suppressed one block at a ti-me.

• M02, M30: Programmable coordinate rotation and zero offset are deleted, where-as settable coordinate rotation and zero offset are retained (setting da-ta).




Further features:

• The programming of simultaneous axes is not possible in conjunction with coordinate rota-tion.

• Coordinate rotation can run in ”AUTOMATIC” mode.• Coordinate rotation is channel specific ; during ”SIMULATION” the coordinate rotations

entered for channel 3 (simulation channel) are active.• Coordinate rotation is not taken into account for the ”ACTUAL VALUE DISPLAY”.• Circular interpolation must not be programmed immediately after coordinate rotation.• If grinding wheel radius compensation is selected:

– The turning centre (sum of zero offsets) must not be altered.– Angle of rotation ”A” of the settable and programmable coordinate rotation can be alte-

red.

In order to define the path the control requires values for the centre, the radius and the angle.The centre is entered in absolute dimensions for right angle coordinates (X, Y, Z) and on firstprogramming. Any later incremental dimension input (using G91) is always based on the lastcentre programmed. The definition of the centre is modal and can be deleted with M02/M30.

The radius is programmed under address U without sign. The angle is entered under addressA without sign (input resolution 10-5 degrees). It always refers to the first positive axisprogrammed of the centre coordinates (reference axis). The positive direction of this axis isequivalent to an angle of zero degrees. The angle given is absolute or incremental andpositive.



















The addresses for the angle and the radius are enteredin NC MD 5000 and 5001.

3.2.11 Thread grinding, G33/G34/G35

3.2.11 Thread grinding, G33/G34/G35

There are various types of thread as follows:

• Threads with a constant lead• Threads with a variable lead• Single or multiple threads• Threads on cylindrical or tapered blocks• External or internal threads

The following preparatory functions are available for machining threads:

G33 Thread grinding with constant leadG34 Thread grinding with linear lead increaseG35 Thread grinding with linear lead decrease

The thread length is entered under the corresponding path address; start-stop and overrunsections at which the feedrate is increased or reduced must be taken into consideration.

The values can be entered using absolute or incremental position data.

The thread length is entered under addresses I, J and K, according to the axis address.

Path feed must be active for the axes involved in the thread grinding operation.

Example:

The lead is entered under K for longitudinal threads and under I or K for tapered threads. I andK must always be entered using incremental data and without a sign. The standard inputresolution of the thread lead is 1 mm/revolution. The thread lead can be programmed between0.001 to 400,000 mm. If a thread lead of 1 mm is programmed as the input resolution, it ispossible to obtain a resolution of 0.01 mm/revolution with M37.

Right and left-hand threads are programmed by specifying the spindle direction of rotationfunctions M03 and M04.

The spindle direction of rotation and the speed must be programmed in the block prior tothe actual thread grinding operation to permit the spindle to run up to its nominal speed.

Example:

N10 S500 M03 LFN15 G33 Z.. K.. LF

The feed start does not begin until the zero mark is reached on the pulse encoder in order topermit threads to be ground in several steps. This ensures that the tool always enters theworkpiece at the same point on the circumference of the workpiece. The cuts should beimplemented at the same spindle speed to prevent discrepancies in the following error.

The feedrate override switch, the ”FEED OFF” key, the spindle speed override switch and the”SINGLE BLOCK” key have no effect during thread cutting.

The feedrate programmed under F remains stored however, and is effective again when, forexample, G01 is next programmed.

The feedrate F is not programmed here since the feedrate is linked directly to the spindlespeed via a pulse encoder.

3.2.11.4 Multiple threads

Thread cutting always begins at the synchronization point of the zero mark of the pulseencoder. The feed is not enabled unless this signal is received from the digital rotarytransducer. The starting position for cutting the thread can be offset with the aid of theprogram. This makes it possible to cut multiple threads. A turn of a multiple thread isprogrammed in the same manner as a single thread . When the first turn has been fullymachined, the starting position is offset by h' and the next turn is machined.

h'=Thread lead

No. of turns

The various turns must be executed at the same spindle speed in order to avoiddiscrepancies in the following error.

In this example each turn is machined in two steps. When the first turn has been fullymachined, the second turn is machined by offsetting the starting position by h'.

h'= Thread lead/number of turnsh'=6/2=3 mm.

For the 2nd turn the Z coordinate is thus Z118 instead of Z115.

3.2.12 Plane selection, G16/G17/G18/G19


Plane selection is required for the correct calculation of the tool offset data . The planeswhich are defined in the channel-specific machine data 548*, 550* and 552* by their axisnames are accepted as programming planes. Extended axis names are permissible.

Possible planes:

Machine data: 548* 550* 552*Axis names: E V Q1

Plane: G16(E-V) initial setting

Plane: G17(E-V)

Plane: G18(Q1-E)

Plane: G19(V-Q1)

Free plane selection is programmed with G16 <axis names>.

Plane selection G16

The initial setting plane for SINUMERIK 810G/820G is G16. The plane is defined with NC MD548*, NC MD 550* and NC MD 552*.

Initial setting G16 is active when the control is switched on and from software version 2.1.corresponds to the programmed plane G17.




















The machine tool manufacturer can adapt the initialsetting plane to the machine concerned via the machine

data.

Type 30 cannot be used if G17, G18 and G19

are programmed.




3.3 Point-to-point control


Programming of simultaneous axis movements

The programmed simultaneous axes are not interpolated with each other. The programmedfinal positions are reached at different times, depending on the paths and feedrates. Up to fouraxes can be traversed simultaneously. Interpolating axes with path feed and simultaneous axescan be programmed in one block.

The position of the F word in the block defines whether the programmed axes are tointerpolate with each other or be traversed simultaneously.

Simultaneous axes are programmed by entering the feedrate directly after the programmedaxis value.

The following applies for programmed path feed:

• All those axes which are not programmed with simultaneous feed FSIM in the current blockor any previous block are traversed with path feed FBAHN.

• It always applies to all axes. Simultaneous feedrates from preceding blocks aredeselected.

• The current path feed is replaced by the programmed value.• Simultaneous feedrates can be programmed in the same block.

Any axes for which no simultaneous path feed has been programmed, traverse at the pathfeed last programmed.

FBAHN can be programmed in three different ways:

• F word alone in the block or in a block without axis paths• F word at the beginning of the block• F word after at least two axis paths

FSIM can only be programmed in one way:

• F word after one axis path

Simultaneous path feed FSIM must be active, i.e. , must be programmed in the NC block forG05, G07, G27 or G163 or the reciprocating functions G181 to G185.

Simultaneous axes must not be programmed with any of the following functions:

• Coordinate rotation• Thread cutting (G33 to G35)• Grinding wheel radius compensation• Mirroring (from PLC)• Continuous-path mode (G64)• Polar coordinates

Erratum:

The values for the sparking-out time and the retraction path are given asF1=<value> and F0=<amount> in the Standard Documentation.

This should be: I1=<value> and I0=<amount>

Note:

In a block with several feedrates there must be a difference between the actual position andthe target position programmed in this block so that the retraction path programmed withaddress I0=<amount> can be traversed.

The path programmed with I0 is traversed automatically in rapid traverse in the oppositedirection to the direction of travel programmed in this block.

The setpoint feedrate is updated according to the external inputs when the feedrate overrideswitch is not in the ”zero” position.

In the following examples, the X axis is the infeed axis, the Z axis is the workpiece rotatingaxis, that is, the reference axis. The oblique axis marked ”U” is the machine axis, i.e. themachine moves mechanically in this direction. The workpiece coordinates are programmedand displayed as Cartesian coordinates.

The setpoint value for the U axis is calculated from the infeed value and the angle of theoblique axis entered in the machine data.

Diameter programming can be used to calculate the infeed axis X. Circular interpolationbetween the oblique axis and the reference axis is also possible.

Axis movement depends on the preparatory function programmed. The paths followed by thegrinding wheel reference point in the Cartesian coordinate system (X/Z) are displayed.

Where the U axis is oblique, the grinding wheel reference point is programmed and moved inCartesian coordinates. Programming a movement in the X axis causes an additional movementof the Z axis, so that the grinding wheel reference point does not change in relation to the Zaxis. The actual value display for the Z axis does not change.

3.7.2 Oblique plunge-cut grinding, G05


G05 is programmed to obtain an oblique plunge-cut motion according to the angle of theoblique axis in MD 296.

The axes involved in the oblique plunge-cut grinding must be programmed with simultaneousfeed.

The function is non-modal.

The movement in X is programmed with Cartesian coordinates and results in the movement ofthe U axis (machine axis). The path followed by the U axis can be calculated as follows:

The movement programmed in the X axis is displayed. As soon as the axis moves, the actualvalue display for the Z axis (reference axis) changes by the value Zdispl=Xprogr·tan . Thismeans that the new position of the grinding wheel reference point in the Z axis resulting fromthe oblique movement of the U axis is used in the calculation of the actual value display.

If the machine has an oblique grinding wheel, the X axis (infeed axis) is programmed withCartesian coordinates. Programming a movement in the X axis, however, causes an additionalmovment in the reference axis (Z axis) and the grinding wheel reference point travels along theresulting path.

Programming G05 ... corresponds to programming G01 X ... Z ... with Z = X tan . If G05 isprogrammed, the positional data is automatically generated from the angle of the oblique axis.

3.7.3 Compensating movement, G07

G07 is used in oblique plunge-cut grinding to produce a compensating motion in the referenceaxis (Z axis) so that the grinding wheel can then be moved into position to perform obliqueplunge-cut grinding with G05. The G function is non-modal. Simultaneous feed with G01 mustbe active for the reference axis, i.e., programmed in the G07 block.

The sum of all the offsets must not be altered in the G07 block. A new zero offset group or Dno. can be selected before the G07 block if the oblique axis has been programmed oncebefore the G07 block or if STOP DEC (@714) has been programmed before the G07 block.

The function positions the grinding wheel reference point on a path that will lead to the desiredend position with the G05 block. The coordinates of the end position required to perform theoblique plunge-cut grinding can be programmed in the G07 block according to absolute orincremental dimensions.

Explanation:

a) Xdispl=Xdispl or Zdispl=Zdispl means that the actual value display does not change

b) ...+Xprogr.·tan is the compensation amount for the reference axis which is produced bythe movement of the oblique axis.

Where G90 is programmed, the display value Xdispl or Zdispl corresponds to the programmedvalue.

Where G91 is programmed, the display value Xdispl or Zdispl corresponds to the change in thedisplay value according to the programmed travel increment and plus the compensation valueif applicable.

8 Tool Offsets


8.3 Tool offset without using the wheel radius compensation


Different tool offsets can be programmed in channels 1 and 2. The active tool offset for thedisplayed channel is used to calculate the actual display. The tool offset displayed in theAUTOMATIC display is valid for all the axes of a particular channel.

8.4 Tool offset using wheel radius compensation


Different tool offsets can be programmed in channels 1 and 2. The active tool offset for thedisplayed channel is used to calculate the actual value display. The tool offset displayed in theAUTOMATIC display is valid for all the axes of a particular channel.

Wheel radius compensation cannot be implemented in channel 2.


08.91 9 Wheel Radius Compensation

9.1 Selection of wheel radius compensation

9 Wheel Radius Compensation


9.1 Selection of wheel radius compensation


Before wheel radius compensation is selected with G41 or G42, the axes involved in the wheelradius compensation must have moved to take account of the tool length offsets and the zerooffset, i.e. the total of the length offsets and zero offsets must not change in the approachblock .

This ensures that no unnecessary compensating movements have to be carried out and thatthe contour is not violated.

10.2 Cycle call via G function

10 Cycles


10.2 Cycle call via G function

In software version 2.1, cycles L81 to L89 cannot be called modally using G functions G81 toG89.


08.91 11 Programming of Cycles

11.9 NC-specific functions

11 Programming of Cycles













Main group 7/Subgroup 1: Individual functions

@710 <VAR1> <VAR2> (Reference preparation)

The function is not implemented in software version 2.1.

@711 <VAR1> <VAR2> <VAR3> (Intersection point calculation)

The function is not implemented in software version 2.1.

@714 (Stop decoding until buffer is empty)

The function described for the @714 command in the Standard Documentation has beenextended so that the sum of all the offsets is updated for the next G91 block but nottraversed. This means that only the incremental path actually programmed is traversed inthe next block. An altered offset sum before the @714 block will not have any influenceon the traversing path of the G91 block.

If there is no @714 command before the G91 block, the offset difference is traversed inaddition to the incremental path.

If the first traversing block in the part program is programmed with G91, the sum of theoffsets is traversed in addition to the programmed value. If a @714 command isprogrammed before the G91 block, this will cause only the programmed incremental pathto be traversed.











Main group 7/Subgroup 2: Measurement functions

@720 <VAR> <Wert> (Inprocess measurement referred to machine zero)

This command is programmed in measuring cycles.

With this measurement function, the actual values of the moving axis or axes are recordedat the point when an input signal is received from the probe. The actual values of the axesprogrammed in this block are stored in the order in which the axes were programmedstarting at the R parameter defined by <VAR>. The control then generates a ”Deletedistance to go”, i. e., the distance to go (setpoint/actual value difference) for all the axes isdeleted. The braking distances of the axes are traversed, i.e., the following error isremoved.

The next traversing block can either be programmed with G90 in absolute dimensions orwith G91 in incremental dimensions. ”STOP DEC” (@714) must however be programmedbefore the G91 block.


11 Programming of Cycles 08.91


The measurement input number (1 or 2) is defined in <Value>.

Path feed must be active for the axis or axes in the measuring block.

Note:

The function ”inprocess measurement” is only executed when measuring circuit monitoring isactivated in the machine data for all the axes in the machine and none of the axes have beendeclared as a ”parking axis”.

Example:...N10 @720 R900 K1 X220 Y30 F50 LF...

When probe 1 is activated, the positions for the X and Y axis are loaded in R parameters 900and 901.

11.11 Operator guidance macro (OGM)











Main group c/Subgroup c: Retransformation

@ccc (Identifier for the beginning of OGM data)


The beginning indentifier @ccc is generated when the OGM name is configured after theOGM no. as follows: (OGM: <name>). A data block of this kind can later be editedgraphically using the function ”Retransformation”.

Example: Structure of operator guidance macro 7

Configured data block

% BFM 7

(OGM: PLUNGE GRINDING1)

N 150 G 100 G 101 R10= 102 R11= 103 R12= 104 R13= 105 LFR140= 106 R15= 107 L901 LF

This operator guidance macro 7 would, for example, insert the following block at the position inthe part program marked by the cursor.

@ccc (X:Z:Y) N2 G01 G90 R10=50 R11=20 R12=15 R13=25 LFR14=27 R15=39 L901 (OGM: PLUNGE GRINDING1) LF

Note:

The length of a block must be no more than 120 characters and the length of an operatorguidance macro no more than 12 characters. The first statement must be a block number(N ...) to make it easier to find the block when it is next edited. The operator guidance macromust not generate a block number or a comment at the beginning of the block in a partprogram.
