2.4.4
Smooth approach and retraction
2.4.4.1
Function
Significance
The SAR (Smooth Approach and Retraction) function is used to achieve a tangential
approach to the start point of a contour, regardless of the position of the start point.
The approach behavior can be varied and adapted to special needs using a range of
additional parameters.
The two functions, smooth approach and smooth retraction, are largely symmetrical. The
following section is, therefore, restricted to a detailed description of approach; special
reference is made to differences affecting retraction.
Sub-movements
There are maximum 4 sub-movements in case of soft retraction and approach with the
following positions:
•
Start point of the movement P
0
•
Intermediate points P
1
, P
2
and P
3
•
End point P
4
Points P
0
, P
3
and P
4
are always defined. Intermediate points P
1
and P
2
can be omitted,
according to the parameters defined and the geometrical conditions.
On retraction, the points are traversed in the reverse direction, i.e., starting at P
4
and ending
at P
0
.
