CYCLE800 checklist for the identification of the machine kinematics

Note

Identification of the machine kinematics according to DIN 66217 or ISO 841-2001

This checklist does not claim to be complete.

● Do the 3 linear axes of the machine that are active for the transformation form an orthogonal

coordinate system? Geometry axes XYZ

● How many swivel kinematics does the machine have?

Combinations of two (or one) rotary axis and the three linear axes are always formed.

Offset vectors I1 to I4

The vectors always contain three components, which are the reference to the machine axes (X,

Y, Z). The positions in the kinematic chain are measured by the machine manufacturer; they are

always relevant with respect to a swivel head / swivel table (swivel data set). Offset vectors I1

to I4 refer to the non-swiveled state of the rotary axes (machine kinematics basic setting).

The machine kinematics used do not need to be fully implemented. However, be aware that the

traversing range in the swivel planes may be restricted. If machine kinematics are to be

implemented with just one rotary axis, this must always be declared as the 1st rotary axis.

Name of the swivel data set

Figure 18-4

Dialog to input parameters for the swivel data set

If multiple swivel data sets are declared in each NC channel, a name is assigned to each swivel

data set: $TC_CARR34[n]

No name needs to be specified if the swivel-mounted tool holder is not exchangeable (i.e. one

swivel data set per channel).

The name of the swivel data set may only contain characters that are permissible for NC

programming: A...Z, 0...9 and _ !

If multiple NC channels have been set up, note the settings in MD28085. If a TO unit is assigned

to multiple NC channels, the channel display in the dialog corresponds to the TO unit.

The following identifiers should be preferably chosen for the names of the rotary axes:

● Rotary axis rotates around machine axis X → A

● Rotary axis rotates around machine axis X → B

● Rotary axis rotates around machine axis Z → C

For automatic rotary axes, the channel names of the corresponding NC rotary axes must be

entered (see $TC_CARR37[n] TENS and HUNDREDS position: Automatic mode). For manual

(manually adjustable) and semiautomatic rotary axes, you can use any axis identifier (up to six

letters or digits).

Manual and semiautomatic rotary axes are not defined in the NC. With manual rotary axes, the

value for the angular range is entered in the dialog box. Semiautomatic rotary axes are moved

mechanically on the machine, e.g. through a coupled spindle. The adaptations for this can be

made in the CUST_800 manufacturer cycle. The value for the angular range must not be

specified, the rotary axis positioning is performed automatically.

Notes on the setting Basic position of the kinematics ¹⁾

For turning machines (1st technology is turning) with a B axis, you can set whether the tool is

oriented toward "-Z" or toward "-X" in the basic position of the kinematics. This setting is taken

into account for "Align tool" and for "Swivel plane".

Align tool

● For "Align tool", the programming of beta and gamma is machine-independent.

● With the basic position setting "Working plane" or "-Z", beta = 0 also corresponds to this

basic position (compatibility).

● With the basic position setting "-X", the B axis is re-oriented through 90° for beta = 0.

Swivel plane (new swivel plane)

● With the basic position setting "Working plane" or "-Z" and active working plane G17, there

is no new tool orientation for swivel plane to basic position (compatibility).

● With the basic position setting "-X" and active working plane G17, the tool orientation is

rotated 90° around Y for swivel plane to basic position.

Therefore, with the basic position setting "-X", milling is possible in a swiveled plane in different

working planes (G17 or G19).

The following settings and programming is not permitted and results in error messages:

● Swivel plane, basic position -Z and G18 or G19 active

● Swivel plane, basic position -X and G18 active

18.7 Swiveling

Parameter CUTMOD in CYCLE800

Distinction between calls:

● The CUTMOD NC function is activated when data set 2 is called in the NC program

(CYCLE800 align turning tool). This means that the cutting edge position or the tool

reference point is updated corresponding to the tool orientation:

● When calling a swivel data set for rotational operation in the NC program (CYCLE800 align

tool), the CUTMOD NC function is activated. The cutting edge position, tool angle, cut

direction and tool reference point are thus calculated in accordance with the current tool

orientation following the "Align tool" function.

Additional information

A more detailed description of parameter CUTMOD is provided in the

Function Manual Tools

18.7.5

Manufacturer cycle CUST_800.SPF

Function

During swiveling, all axis positions are approached using the CUST_800.SPF cycle. The call is

exclusively made from the swivel cycle CYCLE800 or from the cycles

E_TCARR (ShopMill) or F_TCARR (ShopTurn).

In cycle CUST_800.SPF, the function markers (_M2: to _M59) are prepared and documented.

Also refer to the following "Structogram CYCLE800".

There are extensions in the CUST_800.SPF cycle for the "Turning on milling machine" function,

see Chapter "Adaptations for CUST_800 (Page 457)".

Note

If you modify the CUST_800, ensure that the G commands of the G groups used are restored

at the end of the CUST_800 (versions S_G_1 to S_G_5!).

18.7 Swiveling

Retract prior to swiveling

If the CUST_800.SPF cycle is not modified, the Z axis (marker _M41) or the Z axis followed by

the X, Y axes (marker _M42) are first traversed in the Machine to the positions when retracting

prior to swiveling. The freely available position values are specified in the system variables

$TC_CARR38[n] to $TC_CARR40[n]. When retracting, the active tool cutting edge is

deselected (D0) and is reselected after retraction.

If retraction in the tool direction has been declared, the tool axis is retracted to the software end

position (maximum in tool direction) or by an incremental distance away from the tool in the tool

direction. The tool lengths are taken into account accordingly.

Different coordinate systems for milling and turning

In boring mills, the rotary table usually rotates around the Y axis (B axis). During turning, the

workpiece must rotate around the Z axis (C axis) in the G18 plane. Therefore, different

coordinate systems must be used on this machine for milling and turning.

Settings

Set the appropriate coordinate system via the following channel-specific machine data (values,

for example, for boring mills):

MD52000 $MCS_DISP_COORDINATE_SYSTEM

= 16

Y up, Z to the right

MD52001 DISP_COORDINATE_SYSTEM_2

moment of inertia. During axis movements, inaccuracies in workpiece machining can arise.

Using cycle CYCLE782, you can automatically adapt the controller settings of the drive or the

dynamic response parameters of the axes to a specific situation. In this way, you achieve faster

and more accurate machining on the workpiece.

Software option

To use this function, you need the software option:

"Intelligent load adjustment"

Note

If the option "Intelligent load adjustment" is set, bit 20 is activated for MD19321

$ON_TECHNO_FUNCTION_MASK_1 and the softkeys "Adapt to load" and "Adaptation" are

displayed on the input screen.

Configuring the input screen form

Set the load response when opening the input screen form using the following channel-specific

machine data:

MD52212 $MCS_FUNCTION_MASK_TECH

General function screen for all technologies

Bit 18

Enable determining the complete load: Axis empty + workpiece

= 0

The selection separately determine load is enabled in cycle CYCLE782. The deter-

mined load value then only refers to the current workpiece. (default)

= 1

The total load is determined in cycle CYCLE782. The determined load value corre-

sponds to the sum of: Axis empty + workpiece.

Manufacturer cycle CUST_782.SPF

Function

Cycle CUST_782 is called internally by CYCLE782 (determine the load). It is used to execute

the required traverse distances and traverse conditions for determining the load. These are

specific to the machine and must be set accordingly by the machine manufacturer.

Adapting manufacturer cycle CUST_782.SPF

You can execute the following actions with the aid of the _MODE parameter:

Call at the end of CYCLE782

Resetting value for the moment of inertia

Before each determination of the load, the moment of inertia last determined can be reset to a

defined value in the CUST_782 movement profile by writing the following variables.

$VA_RESET_INERTIA_TOTAL[ax]

Resetting the moment of inertia estimator

= -1

Reset moment of inertia and load

= 0

No action (default when reading)

= 1

Reset moment of inertia

ax = axes in the system

To ensure that the old moment of inertia does not have any influence on the new result, reset

the last estimated moment of inertia prior to each new traversing with the parameterization = 1.

This will allow the estimation results determined to be reproduced.

Should you wish to reset the estimated load torque at the same time (e.g. the friction force), use

the parameterization = -1.

Note

System variable $VA_RESET_INERTIA_TOTAL is only available for SINAMICS drives. It

describes the SINAMICS parameter p1565.

Axis/contour tolerance

The distinguishing feature between "Advanced Surface" and "Top Surface" functions is as

follows:

For "Advanced Surface", the axis tolerance for the linear axes (geometry axes) is transferred

to the CNC with the NC command CTOL.

CTOL = √3 * Axis tolerance

For "Top Surface", the contour tolerance is transferred to the CNC with the NC command CTOL.

Tolerance value = 0: Tolerance value (CTOL) is loaded from the following setting data:

Example: CYCLE832(0,_ROUGH,1) → tolerance value from SD55446 is used.

For milling:

● The probe has been inserted in the tool spindle.

● The probe has been selected in the tool list as type 7xx (probe).

● The probe is activated as tool in the current NC channel.

Tool measurement

To measure tools, an appropriate probe must be located in the machine space so that this can

be reliably and safely reached with a tool in the spindle.

The following tool types are supported with measure tool:

● Milling technology: Tool types 1xx and 2xx

● Turning technology: Tool types 5xx, 1xx and 2xx

overwritten in the input screen when calibrating. To do this,

SD54762 $SNS_MEA_FUNCTION_MASK_TOOL bit 4 must be set to 1.

MD51757 $MNS_J_MEA_COLL_MONIT_FEED

Position feedrate in mm/min, in the working

plane for active collision monitoring

= 1000

Default value

MD51758 $MNS_J_MEA_COLL_MONIT_POS_FEED

Position feedrate in mm/min, in the infeed

axis for active collision monitoring

= 1000

Default value

In the following setting data, index [k] stands for the number of the current data field (probe

number -1) of the probe.

Example

If the general setting data SD54632 $SNS_MEA_T_PROBE_ALLOW_AX_DIR[k] has the value

123, the tool probe is calibrated as follows in the G17 plane:

● X in both directions

● Y only in plus direction

● Z only in minus direction

SD54631 $MNS_MEA_T_PROBE_DIAM_LENGTH[k]

Effective diameter of the tool probe

for length measurement.

= 0

Default value
