Siemens SINUMERIK Series Operating Manual page 423

The following machining variants are available:
● Mill rectangular pocket from solid material.
● Predrill rectangular pocket in the center first if, for example, the milling cutter does not cut
in the center (program the drilling, rectangular pocket and position program blocks in
succession).
● Machine pre-machined rectangular pocket (see "Solid machining" parameter):
– Complete machining
– Post machining
Depending on the dimensions of the rectangular pocket in the workpiece drawing, you can
select a corresponding reference point for the rectangular pocket.
Note
Predrilling
If the programmed input parameters, deviating from Pocket3, result in a longitudinal slot or a
longitudinal hole, then in the cycle, from Pocket3, the corresponding cycle to machine slots
(Slot1 or Longhole) is called. In these cases, the insertion points can deviate from the pocket
center point.
Note this special feature if you wish to predrill.
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Approach/retraction
1. The tool approaches the center point of the rectangular pocket in rapid traverse at the height
of the retraction plane and adjusts to the safety clearance.
2. The tool is inserted into the material according to the chosen strategy.
3. The rectangular pocket is always machined with the chosen machining type from inside
out.
4. The tool moves back to the safety clearance at rapid traverse.
