Tilting the working plane of machines with rotary axes allows you to machine several workpiece sides in just one clamping setup, for example.
The tilting functions also allow aligning a workpiece clamped at an incorrect angle.

The tilting functions also allow aligning a workpiece clamped at an incorrect angle.
Types of machining according to number of axes
3+2 axes machining requires at least two rotary axes. Removable axes as an additional top table are also possible.
To calculate the tilting angles, the control requires a kinematics description prepared by the machine manufacturer.
Tilting the working plane defines the orientation of the working plane coordinate system WPL-CS.
The position of the workpiece datum and consequently the orientation of the working plane coordinate system WPL-CS can be defined by using the TRANS DATUM function before tilting the working plane in the workpiece coordinate system W-CS.
A datum shift is always in effect in the active WPL-CS, meaning after the tilting function if applicable. If the workpiece datum is shifted for the tilting process, an active tilting function may have to be reset.
In practice, workpiece drawings show different specified angles, which is why the control offers different PLANE functions with different options for defining angles.
In addition to the geometric definition of the working plane, every PLANE function allows specifying how the control positions the rotary axes.
If the geometric definition of the working plane results in no unambiguous tilting position, the desired tilting solution can be selected.
Depending on the defined angles and the machine kinematics, there is a choice whether the control positions the rotary axes or orients the working plane coordinate system WPL-CS exclusively.
As soon as the working plane has tilted, the General status display in the Positions workspace contains an icon.
When deactivating or resetting the tilting function correctly, the icon indicating the tilted working plane must disappear.
When the working plane is tilted, the POS and TRANS tabs in the Status workspace contain information about the active orientation of the working plane.
When defining the working plane by using axis angles, the control displays the defined axis values. All alternative geometric definition options display the resulting spatial angles.
The control provides the following PLANE functions:
Syntax element | Function | Further information |
---|---|---|
SPATIAL | Defines the working plane by means of three spatial angles | |
PROJECTED | Defines the working plane by means of two projection angles and one rotation angle | |
EULER | Defines the working plane by means of three Euler angles | |
VECTOR | Defines the working plane by means of two vectors | |
POINTS | Defines the working plane by means of the coordinates of three points | |
RELATIV | Defines the working plane by means of a single spatial angle with incremental effect | |
AXIAL | Defines the working plane by means of a maximum of three absolute or incremental axis angles | |
RESET | Resets tilting of the working plane |
If necessary, you can edit Cycle 19 WORKING PLANE. However, you cannot insert the cycle again, because the control no longer offers the cycle for programming.
Refer to your machine manual.
This function must be enabled and adapted by the machine manufacturer.
The machine manufacturer must take the precise angle into account (e.g., the angle of a mounted angle head in the kinematics description).
You can also orient the programmed working plane perpendicularly to the tool without defining rotary axes (e.g., when adapting the working plane for a mounted angle head).
Use the PLANE SPATIAL function and the STAY positioning behavior to swivel the working plane to the angle specified by the machine manufacturer.
Example of mounted angle head with permanent tool direction Y:
11 TOOL CALL 5 Z S4500 |
12 PLANE SPATIAL SPA+0 SPB-90 SPC+0 STAY |
The tilt angle must be precisely adapted to the tool angle, otherwise the control will generate an error message.
