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
.
18.5.4.2 Parameters
The response of the smooth approach and retraction function is determined by up to 9 parameters:
Non-modal G code for defining the approach and retraction contour
This G code cannot be omitted.
•
G147
: Approach with a straight line
•
G148
: Retraction with a straight line
•
G247
: Approach with a quadrant
•
G248
: Retraction with a quadrant
•
G347
: Approach with a semicircle
•
G348
: Retraction with a semicircle
