Adapting The Fir Jerk Filter To The Dynamic Mode (Calcfir) - Siemens SINUMERIK 840D sl Programming Manual

Work preparation
3.15 Axis functions
Block search
● Block search without calculation
CADAPTON/CADAPTOF instructions that are programmed between the beginning of the
program and target block are ignored. Users must select the search target so that the
adaptations relevant for the machining section are selected.
● Block search with calculation at the contour or at block end point
The activation and/or deactivation commands - as well as possible programmed input
values - are collected, and the actual status at the end of the search is output with the search
action blocks.
● Block search with calculation in Program test (SERUPRO) mode
When SERUPRO is deactivated, the status of the adaptations achieved using the
CADAPTON/CADAPTOF instructions is transitioned into real operation.

Adapting the FIR jerk filter to the dynamic mode (CALCFIR)

After changing the dynamic mode, to achieve identical damping action and contour precision
for all axes in the channel for which an FIR low-pass jerk filter is active, using the predefined
CALCFIR procedure, the dynamic response-dependent FIR filter settings of the limiting linear
axis of the interpolation group can be transferred and set for all other channel axes with active
FIR low-pass jerk filter.
Application
CALCFIR is used in the CUST_832 manufacturer cycle.
Standard workflow
CYCLE832 is programmed at the start of an NC program for free-form surface machining.
When executing the program, CYCLE832 calls manufacturer cycle CUST_832, and the
predefined CALCFIR procedure inserted by the machine manufacturer in CUST_832, is
executed.
Effectiveness
The filter settings overwritten by CALCFIR remain active until they are again overwritten by the
next CALCFIR call. This is always required, if, using a command of G group 59 (dynamic
response mode for path interpolation), a change to the actual dynamic response mode is
programmed.
Response when the control system powers up / channel reset / end of program reset
When the control system powers up, and for a channel/end of program reset, the FIR filter
settings are activated to match the initial setting of G group 59.
