Detailed Description
2.7 Basic tool orientation
Basic logic functions: Tool Offset (W1)
130 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Plane change
A change of plane causes a change in orientation.
The following rotations are initiated:
When changing from: Rotations
G17 ⇒ G18:
G18 ⇒ G19:
G19 ⇒ G17:
Rotation through -90 degrees about the Z axis
followed by rotation through -90 degrees about the X
axis
G17 ⇒ G19:
G18 ⇒ G17:
G19 ⇒ G18:
Rotation through 90 degrees about the X axis
followed by rotation through 90 degrees about the Z
axis
These rotations are the same as those that have to be performed in order to interchange the
components of the tool length vector on a change of plane.
The basic orientation is also rotated when an adapter transformation is active.
If the following setting data is not equal to zero, the tool orientation is not rotated on a
change of plane:
SD42940 $SC_TOOL_LENGTH_CONST (change of tool length components on change of
planes).
Tool length components
The components of the tool orientation are treated the same as the components of the tool
length, with respect to setting data:
SD42910 $SC_MIRROR_TOOL_LENGTH (Sign change tool wear when mirroring).
SD42950 $SC_TOOL_LENGTH_TYPE (allocation of the tool length components
independent of tool type)
Therefore the components are changed respectively and assigned to the geometry axis.
