W1: Tool offset
18.6 Toolholder with orientation capability
Basic Functions
1510 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
• The two rotary axes intersect at one point.
All components of l
2
are therefore zero.
• The first rotary axis lies in the x/z plane, the second rotary axis is parallel to the x axis.
These conditions define the directions of v
1
and v
2
(the lengths are irrelevant, provided that they are not equal
to zero).
• The reference point of the toolholder lies 200 mm in the negative x direction viewed from the intersection of
the two rotary axes.
This condition defines l
1
.
