Bit 1 = 1

Swivel data set with two rotary axes

used for standard swiveling

Bit 2

= 1

In a singular position, for which there is an unambiguous solution due to the alignment

of the coordinate axes that are vertical to the orientation, the value 1 is displayed in the

system variable $P_TCSOL as the number of solutions.

= 0

This version is required to ensure compatibility with older software versions. Two solu-

tions are displayed; the angles about the orientation axis differ by 180 degrees.

MD20360 $MC_TOOL_PARAMETER_DEF_MASK

Tool parameter setting

Bit 10 = 1

The tool portion of an active orientable tool carrier is retained at T0 or D0 (no tool).

Used for machine kinematics, types "T" and "M".

See parameter $TC_CARR34

Bit 19 = 1

A tool's change in orientation caused by an oriented tool holder remains at T0 or D0 (no

tool).

Bit 19 acts only with bit 10 = 1.

MD21186 $MC_TOCARR_ROT_OFFSET_FROM_FR

Offset of the rotary axes for an oriented

tool holder from the work offset of the ro-

tary axis.

= 0

In CYCLE800, the WCS is recalculated when there is a value in the work offset (WO) of the

rotary axes.

If values are entered in the work offset of the rotary axes of the active swivel data set, the

basic position of the swivel data set and therefore also the basic position of the WCS can

change.

= 1

A value in the ZO of the rotary axes acts as offset of the oriented tool holder. The Work

remains unchanged.

MD21186 may not be rewritten in a program with call CYCLE800.

The setting MD21186 = 0 is only suitable for a swivel data set in which one of the available rotary

axes rotates exactly around the tool axis. In this way, a useful rotation of the WCS can be

calculated in CYCLE800 when values are entered in the zero offset of the rotary axes. For

example, for a swivel table with rotary axis A around X and rotary axis C around Z for a basic

position of the kinematics in G17.

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.

• Which machine components are concerned?

Swivel head, swivel table or swivel head and rotary table.

19.7 Swiveling

• What are the names of the rotary axes of the kinematics?

Manual rotary axes are permitted and do not have to be declared in the NC.

• What is the 1st or 2nd d rotary axis of a swivel data set?

• Is the traversing direction of the linear axes and the rotary axes correct? Right-hand rule

Rule: If the linear axis or the rotary axis moves the workpiece, the direction of motion of the

axis and also the sign of the rotary axis vector change.

• What is the initial setting of the kinematics?

This defines the tool orientation and the plane G17, G18, G19.

• Which rotary axis rotates around which axis of the coordinate system or the machine

axis (axes)?

This defines the rotary axis vectors of the kinematics.

Example 1:

Head kinematics. Rotary axis 2 rotates around axis Y → rotary axis vector V2xyz = 0,1,0

Example 2:

Table kinematics. Rotary axis 1 rotates around axis X → rotary axis vector V1xyz = -1,0,0

19.7.3

Setting up a tool carrier/swivel data set

Defining a tool carrier/swivel data set

You must create a tool carrier (tool holder) for every swivel head, swivel table or each swivel

head/swivel table combination.

Tool carriers can be declared in several channels. A tool carrier can be defined as classic or via the

kinematic chain.

A classic tool carrier comprises the parameters $TC_CARR1[n] to $TC_CARR65[n]

n = number of the tool carrier.

The geometry of the tool carrier based on the kinematic chain comes from the chain. There are

also other descriptive parameters $TC_CARR_KIN...[n] and $TC_CARRxx[n].

If all preconditions from Chapter "Technology cycles for swiveling (Page 423)" are met, you can

assign the tool carrier parameters via the input mask

in the "Setup" → "NC" → "Transformation" operating area.

When you create a new tool carrier here, you can choose if the parameters should be assigned

as classic or via the chain.

Programming with appropriate value assignment is also possible in an NC program. The

parameters of the tool carrier are immediately effective after the program has started.

swivel data set: $TC_CARR34[n]

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

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".

19.7 Swiveling

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

Offsets I1 to I4 $TC_CARR1[n] ... $TC_CARR20[n]

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 (tool carrier).

Offsets I1 to I4 refer to the non-swiveled state of the rotary axes (basic setting: machine

kinematics). 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.

Manually adjustable rotary axes (manual mode) are possible with and without measuring

systems and can be used with "simple machines".

Rotary axes that are positioned by an additional mechanical system, can be declared in the

"Semiautomatic" mode.

Example 2a: Swivel head 2 "HEAD_2" tool carrier based on kinematic chain

In order to map the kinematics in the machine, we recommend mapping the kinematics as they

actually are with regard to the kinematic chain. The drawing on the left shows how the vectors

are specified to map the kinematics in such a way that reflects how the machine actually is. The

tool carrier starts at the pivot point of the B axis followed by the C_OFFSET up to the actual pivot

point of the C axis with an orientation of (0,1,1). The offset then connects to the reference point

of the tool. However, the tool carrier can also start at the pivot point of the C axis (as is usual with

classic). If the swivel head is firmly attached to the machine and the kinematics are closed, the

result of the description is the same. If there are multiple swivel heads on the machine and the

kinematics are open, the first kinematics description is recommended.

Schematic representation of the chain

Once the machine's kinematic chain has been created, various tool carriers can be created on

this basis.

For turning machines with an additional rotary axis B, the tool can be aligned or swiveled on the

X/Z plane. If the machine has a counterspindle, you can, for example, work with a tool

alternating between the main spindle and counterspindle.

You can create the following tool carriers to use the "Align tool" and "Swivel plane" functions:

Milling machine with B axis for turning

You can configure a milling machine with a B axis (rotation around Y) so that turning is possible.

To do so, turning technology is set up as an extended technology.

More information is provided in Chapter "Turning on milling machines (Page 481)"

The following example refers to a milling machine with a rotary axis around Y (B), a rotary axis

around Z (C) and a main spindle (SP) in the tool direction Z (G17).

The following static transformation is created to use the "Align tool" functions.

A new transformation with 2 axes of rotation in the head and one in the table is created in the

"Transformations" operating area:

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.

More information

A more detailed description of parameter CUTMOD is provided in the

Tools Function Manual.

19.7.7

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 marks (_M2: to _M59) are prepared and documented. Also

refer to the following "Structogram CYCLE800".

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

Position of the coordinate system (variable)

= 16

Y up, Z to the right

MD52001 DISP_COORDINATE_SYSTEM_2

Coordinate system for turning on milling machines

(variable)

= 0

Z up, X to the right

Describe the rotation of the coordinate system as follows at the _M70 marker in the

CUST_800.SPF cycle:

_M70:

; Rotation of the coordinate system for turning

19.9 Load-dependent controller setting

Further setting

MD53350 $MAS_ILC_BASE_VALUE

Basic inertia of the axis

= 0

(default)

The result for ascertaining loading of the axis without workpiece is stored in this

machine data.

This value must be determined only once when commissioning the machine.

It is required for support of the function Ascertain loading separately with CYCLE782.

Value output for linear axes

Loading can be determined or specified for linear and also for rotary axes. For linear axes, a mass,

and for rotary axes, a moment of inertia is normally displayed in the measurement result display.

For linear axes, however, the value display may differ depending on the drive type, e.g:

Drive of the linear axis

Value

Unit

Spindles or rotary axes

Moment of inertia

kgm²

Rotary via ball screw, linear mo-

Loading

Additional information

Additional information on using CYCLE782 and its program structure is provided under:

• Operating Manual Universal/Turning/Milling/Grinding

• Programming Manual, NC Programming

19.9.2

CYCLE782: Help screens

For support, help screens are integrated in the input mask for cycle CYCLE782.

The help screens are correctly displayed in the input form if the following channel-specific

machine data are set as appropriate for the machine configuration:

MD52206 $MCS_AXIS_USAGE[n]

Meaning of the axes in the channel

MD52207 $MCS_AXIS_USAGE_ATTRIB[n]

Attributes of the axes

You will find a detailed description of MD52206 and MD52207 in Chapters "Setting the

technology for simulation (Page 161)" and "Activating turning/milling/drilling/grinding

technologies (Page 369)".
