W1: Tool offset
18.6 Toolholder with orientation capability
Specify associated data block values
The following associated data block values are specified for the toolholder shown on a machine
with rotary toolholder:
Description
x component of offset vector l
y component of offset vector l
z component of offset vector l
x component of offset vector l
y component of offset vector l
z component of offset vector l
x component of rotary axis v
y component of rotary axis v
z component of rotary axis v
x component of rotary axis v
y component of rotary axis v
z component of rotary axis v
Angle of rotation α1 (in degrees)
Angle of rotation α2 (in degrees)
x component of offset vector l
y component of offset vector l
z component of offset vector l
Explanations
The toolholder kinematic chosen in the example is such that the two rotary axes form an angle
of 45 degrees, which means that the orientation cannot take just any value. In concrete terms,
this example does not permit the display of orientations with negative X components.
x component of the tool base dimension:
y component of the tool base dimension:
z component of the tool base dimension:
Note
The required data cannot be determined unequivocally from the geometry of the toolholder,
i.e. the user is free to a certain extent to decide the data to be stored. Thus, for the example,
it is possible to specify only one z component for the tool base dimension up to the second
axis. In this case, l
between this point on the second axis and a further point on the first axis. The point on the first
axis can also be selected freely. Depending on the point selected, l
that the reference point (which can also be selected freely) is reached.
In general: vector components that are not changed by rotation of an axis can be distributed
over any vectors "before" and "after" rotation.
