Defining the direction of rotation

In order to ensure that the direction of rotation of the spindle and C axis is correctly displayed on

the user interface and when programming, the correct direction of rotation is executed, you

must make several settings that are coordinated with one another. You must base these settings

on the actual direction of rotation of the spindle/C axis on the machine.

You specify the settings in the following machine data:

MD52207 $MCS_AXIS_USAGE_ATTRIB[n]

Setting up the counterspindle under ShopTurn

Software option

You require the following software option in order to use the counterspindle on your

machine:

"Generic coupling 'CP-STATIC'" or higher

The position to which the counterspindle travels when the program starts is defined in the

following channel-specific cycle setting data:

SD55232 $SCS_SUB_SPINDLE_REL_POS

Retraction position Z for counterspindle

The following channel-specific setting data becomes effective when traveling to the fixed stop:

SD55550 $SCS_TURN_FIXED_STOP_DIST

Distance for travel to fixed stop.

SD55551 $SCS_TURN_FIXED_STOP_FEED

Feedrate for travel to fixed stop.

SD55552 $SCS_TURN_FIXED_STOP_FORCE

Force for travel to fixed stop in %.

Between traveling to the fixed stop and gripping, the counterspindle can retract a short distance

to counteract compressive stress in the workpiece.

SD55553 $SCS_TURN_FIXED_STOP_RETRACTION

Retraction distance before clamping af-

ter fixed stop.

After gripping you can cut off the workpiece. Before doing so, the counterspindle can retract a

short distance with the workpiece to exert tensile stress on the workpiece. This relieves pressure

on the tool when cutting off.

SD55543 $SCS_TURN_PART_OFF_RETRACTION

Retraction distance before cut-off.

After cut-off, you can carry out a cut-off check and for turning, use the "Travel to fixed stop"

function. You can activate/deactivate the cut-off check using the channel-specific cycle setting

data:

SD55540 $SCS_TURN_PART_OFF_CTRL_DIST

Distance for cut-off check.

SD55541 $SCS_TURN_PART_OFF_CTRL_FEED

Feedrate for cut-off check.

SD55542 $SCS_TURN_PART_OFF_CTRL_FORCE

Force for cut-off check in %.

The cut-off is successful when travel to fixed stop fails. The following alarms are output:

Alarm

Alarm text

20091

Axis %1 has not reached the fixed stop.

20094

Limit value during contour turning for

This also applies to residual machining -

stock removal, grooving and plunge

turning.

50

The roughing step for residual machining is not executed, if the material to be removed is less

than 50% of the finishing allowance. The material is only removed when finishing.

Example: If the SD is set to 50% and the final machining allowance is 0.5 mm, any residual material less than

0.25 mm is not removed with the residual machining - but is removed during finishing. If during a

machining step, less residual material is present than defined in the SD, the error message "No material

present" is issued. This means that this residual material roughing step can be omitted because no

machining is performed.

SD55588 $SCS_TURN_CONT_MIN_REST_MAT_AX2

Limit value during contour turning for

removal of residual material in the di-

rection of axis 2 (for G18 X).

This also applies to residual machining -

stock removal, grooving and plunge

turning.

The roughing step for residual machining is not executed, if the material to be removed is less

than 50% of the finishing allowance. The material is only removed when finishing.

As the tool bends during plunge turning, the tool cannot travel right up to the contour during

stock removal. The lateral distance to the last cut by which the next cut is shortened is specified

Spindle speed limitation for current program

Speed limits are programmed in the part program. If the part program is applied, the spindle

speed limits are entered in the setting data and saved there after the end of program.

However, if the modified speed limits must not apply after the end of the program, you can

change the property with the following commands in the GUD block of the machine

manufacturer:

Changing spindle speed limits for the current program only

REDEF $SA_SPIND_MAX_VELO_LIMS PRLOC

Swiveling

19.7.1

Technology cycles for swiveling

Requirement

The commissioning of the machine kinematics is a mandatory requirement for correct swiveling

functionality (CYCLE800). The vectors of the machine kinematics are stored in the tool

parameters $TC_CARR1 to $TC_CARR65. The machine kinematics are stored in the kinematic

chain and be accessed via the $TC_CARR_KIN... tool parameters. The vectors of the machine

kinematics can also be stored in the tool parameters $TC_CARR1 to $TC_CARR65 without the

kinematic chain.

Note

The vectors of the machine kinematics can be corrected with the "Measurement of machine

kinematic" measuring function (CYCLE9960).

To activate the swivel function, there must be at least one tool carrier that can be oriented

(swivel data set) in the NCK, and the workpiece, tool and rotary table reference system frames

must be activated:

dated whenever a tool is changed.
