- When the first rotation axis of the tool and the tool axis do not intersect
Explained below is a mechanism in which the tool axis (spindle rotation
center axis) and the first rotation axis of the tool do not intersect.
When both the master and slave are at 0 degrees, a vector from a point at a
distance of the tool length compensation value plus the tool holder offset
value from the tool center point along the tool axis to a point on the first
rotation axis of the tool is set as an intersection offset vector between the
tool axis and the first rotation axis of the tool in parameters.
- When the rotation axes of the tool do not intersect
Explained below is a mechanism in which the rotation axes of the tool do not
intersect each other.
The figure shown below is an example of a mechanism in which the first and
second rotation axes of the tool do not intersect.
When both the master and slave are at 0 degrees, a vector from a point on the
second rotation axis of the tool to a point on the first rotation axis of the tool
is set as an intersection offset vector between the second rotation axis of the
tool and the first rotation axis of the tool in parameters.
The controlled point can be shifted by setting a shift vector from the point
mentioned above in parameters.
