Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

General
1
The first section provides you with an overview of the available cycles. The following
sections describe the general conditions that apply to all cycles regarding
● Programming the cycles and
● Operator guidance for calling the cycles.
1.1 Overview of cycles
Cycles are generally applicable technology subroutines, with which you can implement
specific machining processes such as tapping a thread or milling a pocket. These cycles are
adapted to individual tasks by parameter assignment.
The system provides you with the technologies
● Drilling
● Milling
● Turning
in various standard cycles.
1.1.1 Drilling cycles, hole pattern cycles, milling cycles, and turning cycles

1.1.2 Cycle auxiliary subroutines
Included in the cycle package is the auxiliary subroutine
● PITCH
This auxiliary subroutine must always be loaded in the control.
General
1.2 Programming cycles
Cycles
14 Programming Manual, 01/2008, 6FC5398-3BP20-1BA0
1.2 Programming cycles
A standard cycle is defined as a subroutine with name and parameter list. The conditions
described in the "SINUMERIK Programming Guide Part 1: Fundamentals" are applicable for
calling a cycle.
Note
The cycles are supplied on diskette/CD or with the relevant software version for HMI
Advanced. They are loaded to the part program memory of the control via the V.24 interface
or from the diskette drive (see operator's guide).
1.2.1 Call and return conditions
The G functions active before the cycle is called and the programmable frame remain active
beyond the cycle.
You define the machining plane (G17, G18, G19) before the cycle call. A cycle operates in
the current plane with the
● Abscissa (1st geometry axis)
● Ordinate (2nd geometry axis)
● Applicate (3rd geometry axis of the plane in space)
In the drilling cycles, the drilling is executed in the axis that is vertical on the plane (3rd
geometry plane). In milling, the depth infeed is carried out in this axis.

1.2.2 Messages during execution of a cycle
During various cycles, messages that refer to the state of machining are displayed on the
screen of the control system during program execution. These messages do not interrupt the
program execution and remain until the next message appears or the cycle is completed.
The message texts and their meaning are listed together with the cycle to which they refer.
Note
You can find a summary of all messages in Appendix A of this programming guide.
Block display during execution of a cycle
The cycle call is displayed in the current block display for the duration of the cycle.
1.2.3 Cycle call and parameter list
The standard cycles use user-defined variables. The defining parameters for the cycles can
be transferred via the parameter list when the cycle is called.
Note
Cycle calls always require a block for themselves.
Fundamentals of standard cycle parameter assignment
The Programming Guide describes the parameter list of every cycle with the
● order and the
● type.
It is imperative to observe the order of the defining parameters.
General
1.2 Programming cycles
Cycles
16 Programming Manual, 01/2008, 6FC5398-3BP20-1BA0
Each defining parameter of a cycle has a certain data type. The parameter being used must
be specified when the cycle is called. In the parameter list,
● variables or
● constants
can be transferred.
If variables are transferred in the parameter list, they must first be defined in the calling
program and assigned values. Cycles can be called
● with an incomplete parameter list or
● by leaving out parameters.
If you want to exclude the last transfer parameters that have to be written in a call, you can
prematurely terminate the parameter list with ")". If any parameters are to be omitted within
the list, a comma "..., ,..." must be written as a placeholder.
Note
No plausibility checks are made of parameter values with a discrete or limited value range
unless an error response has been specifically described for a cycle.
During a cycle call, if the parameter list contains more entries than there are parameters
defined in the cycle, the general NC alarm 12340 "Too many parameters" appears, and the
cycle is not executed.
General
1.2 Programming cycles
Cycles
Programming Manual, 01/2008, 6FC5398-3BP20-1BA0

Note
Transfer parameters and calculation resolution of the NCU
The value ranges defined in the Programming Guide Fundamentals apply to the transfer
parameters of standard and measuring cycles. The value range for angle values is defined
as follows (see ROT / AROT in the Programming Guide Fundamentals):
• Rotation around 1st geometry axis: -180 degrees to +180 degrees
• Rotation around 2nd geometry axis: -90 degrees to +90 degrees
• Rotation around 3rd geometry axis: -180 degrees to +180 degrees
When angle values are passed to a standard or measuring cycle, please note that they must
be rounded down to zero if they are lower than the calculation resolution of the NCU. The
calculation resolution for angle positions on the NCU is specified in machine data 10210
$MN_INT_INCR_PER_DEG.
Example of the parameter _OVR[21] of measuring cycle CYCLE998 (measure angle):
_OVR[21]=-0.000345 ;calculation resolution MD $MN_INT_INCR_PER_DEG=1000
IF ((ABS(_OVR[21] * $MN_INT_INCR_PER_DEG)) < 1)
_OVR[21]=0
ENDIF
Explanation:
If the value of parameter _OVR[21] is less than the programmed calculation resolution, it is
rounded down to zero.
Cycle call
The various methods for writing a cycle call are shown in the following example, CYCLE100,
which requires the following input parameters.
Example
FORM char ;Definition of the form to be machined, values: E and F
MID real ;Infeed depth (to be entered without sign)
FFR real ;Feed
VARI integer ;Machining type, values: 0, 1, or 2
FAL real ;Finishing allowance
This cycle is called via the Cycle100 (FORM, MID, FFR, VARI, FAL) command.
1. Parameter list with constant values
Rather than input individual parameters, you can directly enter the concrete values to be
used in the cycle.
Example
CYCLE100 ("E", 5, 0.1, 1, 0) ;Cycle call
General
1.2 Programming cycles
Cycles
18 Programming Manual, 01/2008, 6FC5398-3BP20-1BA0
2. Parameter list with variables as transfer parameters
You can transfer the parameters as R variables that you define before calling the cycle and
to which you must assign variables.
Example
DEF CHAR FORM="E" ;Definition of a parameter, value assignment
DEF REAL MID=5, FFR, FAL

;Definition of parameters with and without
;value assignments

N20 CYCLE100 (FORM, MID, FFR, VARI,

3. Use of predefined variables as transfer parameters
To assign parameters to cycles, you can also use variables such as R parameters.
Example
DEF CHAR FORM="E" ;Definition of a parameter, value assignment
N10 R1=5 R2=0.1 R3=1 R4=0 ;Value assignments
N20 CYCLE100 (FORM, R1, R2, R3, R4) ;Cycle call
As R parameters are predefined as type real, it is important to ensure that the type of the
target parameter in the cycle is compatible with the type real.
Note
More detailed information about data types and type conversion and compatibility is given in
the Programming Guide.
In the event of type incompatibilities, the system displays alarm 12330 "Type of parameter ...
incorrect".
4. Incomplete parameter list and omission of parameters
If an assigned parameter for a cycle call is not required or if it should have a value of zero, it
can be omitted from the parameter list. In its place, only the comma "..., ,..." is to be written in
order to ensure the correct assignment of subsequent parameters or if the parameter list is
to be closed early with ")".
Example
CYCLE100 ("F", 3, 0.3, , 1) ;Cycle call, 4th parameter omitted
;(i.e., the value zero)
CYCLE100 ("F", 3, 0.3) ;Cycle call, a value of zero is assigned
;to the last two parameters
;(e.g., they have been omitted)

5. Expressions in the parameter list
Expressions, the results of which are assigned to the corresponding parameter in the cycle,
are also permitted in the parameter list.
Example
DEF REAL MID=7, FFR=200 ;Definition of the parameters, value
assignments
CYCLE100 ("E", MID*0.5, FFR+100,1) ;Cycle call infeed depth 3.5, Feed rate 300
1.2.4 Simulation of cycles
Programs with cycle calls can be tested first in simulation.
Function
In HMI Embedded configurations, the program runs normally in the NC and the traversing
motion is traced on screen during simulation.
In HMI Advanced configurations, the program is simulated on the HMI only. This makes it
possible to run cycles without tool data or without prior selection of a tool offset in the MM.
The finished contour is then traversed in the case of cycles that have to include tool offset
data in the calculation of their traversing motion (e.g., milling pockets and grooves, turning
with recess) and a message indicates that simulation without tool is active.
This function can be used, for example, to check the position of the pocket.

1.3 Cycle support in the program editor
The program editor provides cycle support for Siemens and user cycles.
Function
The cycle support offers the following functions:
● Cycle selection via soft keys
● Input screen forms for parameter assignment with help displays
● Online help for each parameter (HMI Advanced only)
● Support of contour input
From the individual screen forms, a program code that can be reset is generated.
1.3.1 Menus, cycle selection
Technology-oriented cycle selection is carried out using soft keys:
Geometry input via the geometry processor or contour definition screen forms
Input screen forms for drilling cycles and drilling patterns
Input screen forms for milling cycles
Input screen forms for turning cycles
After confirming the screen form input by clicking OK, the technology selection bar remains
visible. Similar cycles are supplied from shared screen forms.

Within the screen forms, it is then possible to switch between cycles via soft key, e.g., for
tapping or undercut.
The editor cycle support also contains screen forms that insert a multi-line DIN code in the
program instead of a cycle call, e.g., contour definition screen forms and the input of any
drilling positions.
1.3.2 Functions of the input screen forms
Function
● Many cycles allow you to influence the processing type via the VARI parameter. It often
contains several settings composing one code. In the cycle support screen forms, these
individual settings can be divided among different input fields that can be switched using
the toggle key.
● The input screen forms are changed dynamically. Only the input fields required for the
selected processing type are displayed. Unnecessary input fields are not shown.
● One input may, therefore, automatically assign several dependent parameters. This is the
case for thread cutting, where metric thread tables are currently supported. During the
thread cutting cycle CYCLE97, for example, with input 12 in the input box for the thread
size (parameter MPIT), the thread pitch (parameter PIT) is automatically assigned a value
of 1.75 and the thread depth (parameter TDEP) is automatically assigned a value of
1.074. This function is not active if the metric thread table has not been selected.
● If a screen form is displayed a second time, the most recently entered values are
assigned to all fields. When cycles are called up several times in a row in the same
program (e.g., pocket milling when roughing and finishing), few parameters then have to
be changed.
● In screen forms for drilling and milling cycles, certain parameters may be input as
absolute or incremental values. The abbreviation ABS for absolute and INC for
incremental input is displayed behind the input field. This can be toggled with the
"Alternative" soft key. This setting will remain the next time these screen forms are called.

Free contour programming
Starts the free contour programming, which can be used to enter contiguous contour
sections.

Contour definition programming
These soft keys support the contour definitions that are possible.
These consist of one or more straight lines with intermediary contour transition elements
(radii, chamfers). Each contour element may be preassigned by means of end points or point
and angle and supplemented by a free DIN code.
Example
The following DIN code is generated from the following input screen form for a contour
definition with two straight lines:

Note
Cycles CYCLE81, CYCLE87 and CYCLE89 cannot be parameterized with this support. The
function of CYCLE81 is covered by CYCLE82 ("Drilling, centering" soft key), as is the
function of CYCLE89. The CYCLE87 function is covered by the function of CYCLE88 (soft
keys “Drilling center.” -> “Drilling with stop").
Drilling patterns may be repeated if, for example, drilling and tapping are to be executed in
succession. To this end, a name for the drilling pattern, which is later entered in the "Repeat
Position" screen form, is assigned in the drilling pattern.

Recompiling
Retranslating program codes serves to change an existing program with the help of cycle
support. The cursor is placed on the line to be changed, and the "Recompile" soft key is
pressed.
This reopens the corresponding input screen form, which created the program piece, and
values may be modified.
Entering modifications directly into the created DIN code may prevent recompilation.
Therefore, consistent use of the cycle support is required and modifications are to be carried
out with the help of recompilation.
Default settings for cycle support
Cycles SW 6.4 and higher includes a field for setting data _SC_MASK[10] for cycle support.
These are integer type data and are created as NCK global data in the GUD7_SC.DEF.
Date Value Meaning
_SC_MASK [0] - CYCLE84:
Default settings for the _TECHNO parameter
(set by the machine tool manufacturer during commissioning)
_SC_MASK [1] - CYCLE840:
