Rectangular pocket (POCKET3)

Function
You can use the "Mill rectangular pocket" cycle to mill any rectangular pockets on the face or
peripheral surface.
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 (e.g. for ShopTurn, 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.
Note this peculiarity when you predrill.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
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.
