TURN PLUS | Automatic working plan generation (AWG) submode
Machining sequence – fundamentals
TURN PLUS analyzes the contour in the sequence defined in
Machining sequence. In this process the areas to be machined and
the tool parameters are ascertained. The AWG submode analyzes
the contour using the Machining parameters.
TURN PLUS distinguishes between:
Main mach. operation (e.g. undercutting)
Anc. mach. operation (e.g. type H, K, or U)
Machining location (e.g. outside or inside)
Anc. mach. operation and Machining location refine the
machining specification. If you do not define the Anc. mach.
operation or the Machining location, the AWG generates
machining blocks for all submachining operations/machining
locations.
The following factors additionally influence the working plan
generation:
Geometry of the contour
Attributes of the contour
Tool availability
Machining parameters
In the Machining sequence you define the sequence in
which the machining steps are carried out. If you only
define the Main mach. operation in the Machining
sequence, all of the
comprised by it are executed in a specific sequence.
However, you can also program the submachining
operations and machining locations individually in any
sequence in the Machining sequence. In this case you
should define the associated main machining operation
again after defining the submachining operations. This
way you can ensure that all submachining operations
and locations are taken into account.
The Machining sequence and the program can be
displayed in a horizontal or vertical window layout. Press
the SWITCH VIEWS soft key to switch between the two
views.
Press the CHANGE WINDOW soft key to move the cursor
between the Program and the Machining Sequence
window.
The AWG does generate the work blocks if any required
not
preparatory step is missing, or if the appropriate tool is not
available, etc. TURN PLUS skips machining operations/machining
sequences that do not make sense in the machining process.
Organizing machining sequences:
TURN PLUS always uses the current machining sequence. The
current machining sequence
loading another Machining sequence.
When you open TURN PLUS, the most recently used Machining
sequence is automatically displayed.
