Fig. 2-45 Assignment of the toolholder data
Suitable assumptions were made for the following values in the data block:
• 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
.
