New Functions In Input Screenforms - Siemens SINUMERIK 840D Programming Manual

General

1.5 Cycle support in the program editor (SW 5.1 and later)
Within one screenform, the user may switch between
cycles via softkey, e.g. with tapping or undercut.
The editor cycle support also contains screenforms
that insert a multi-line DIN code in the program
instead of a cycle call, e.g. contour definition
screenforms and the input of any drilling position.

1.5.2 New functions in input screenforms

Function
• In many cycles, the processing type may be
influenced by means of the VARI parameter. It
contains several settings composing one code.
These individual settings are divided up into several
input fields in the screenforms of the new cycle
support. You can switch between the input field with
the Toggle key.
• The input screenforms are changed dynamically.
Only those input fields are displayed that are
required for the selected processing type.
Unrequired input fields are not displayed. In the
example, this is the case with the parameter for the
dressing feedrate.
• One input may therefore automatically assign
several depending parameters. This is the case with
threading which presently supports metric thread
tables. With the threading cycle CYCLE97, for
example, entering 12 in the thread size input field
(MPIT parameter) automatically assigns 1.75 to the
thread pitch input field and 1.137 to the thread depth
input field (TDEP parameter). This function is not
active if the metric thread table has not been
selected.
• If a screenform is displayed a second time, the last
entered values are assigned to all fields.
When cycles are called up several times in a row in
the same program (e.g. pocket milling when
roughing and dressing), only few parameters then
have to be changed.
