Multiple Clamping - Siemens SINUMERIK Series Operating Manual

Multiple clamping

14.20.1 Multiple clamping
The "Multiple clamping" function optimizes tool changes over several workpiece clampings.
This shortens idle times because a tool performs all machining operations in all clampings
before the next tool change is initiated.
In addition to surface clampings, you also have the option of using the "multiple clamping"
function for rotating fixture plates. For this, the machine must have an additional rotary axis
(e.g. A-axis) or a dividing unit.
You can machine not only identical but also different workpieces.
ShopMill automatically generates a single program out of several programs. The tool sequence
within a program remains unchanged. Cycles and subprograms are not opened, position
patterns are processed as closed units.
Requirements
The individual programs must meet the following requirements:
● Only sequence programs (not G code programs)
● Programs must be executable
● Program for the 1st clamping must have been installed.
● No markers/repetitions, i.e. no branches in the program
● No inch/metric switchover
● No work offsets (except ShopMill program header)
● No coordinate transformation (translation, scaling, etc.)
● Contours must have unique names, i.e. the same contour name must not be called in
several different programs.
● The "Starting point" parameter must not be set to "manual" in the stock removal cycle
(contour milling).
● No modal settings, i.e. settings that are effective for all subsequent program blocks (with
multiple clamping for different programs)
