Type of machining for technology database access:
Contour recessing
In this cycle you can specify how the floor element is
machined during the finishing process.
The control evaluates the recessFinishing (602414)
machining parameter for this purpose. If this parameter
is not defined, the floor element is divided in the center.
Cycle run:
1 Calculate the recess positions and the proportioning of cuts
2 Approach the workpiece for the next recess on a paraxial path
from the Start point or from the last recess
3 Finish the first side (taking the optional contour elements into
account) and the contour valley up to a position just before the
recess end point
4 Approach the workpiece on a paraxial path for finishing the
second side
5 Finish the second side (taking the optional contour elements
into account) and the remainder of the contour valley
6 Repeat 2 to 5 until all recesses have been finished
7 Return to the Start point on a paraxial path
8 Move to the Tool change point according to the setting in G14
