Feedrate Reduction With Corner Deceleration (Fendnorm, G62, G621) - Siemens SINUMERIK 840D sl Programming Manual

Note
Workpiece simulation
Up to SW 4.4, no compile cycles are supported, as ofSW 4.4 only selected compile cycles
(CC) are supported for the workpiece simulation.

Solution: Individually handle the missing CC-specific language elements in the part program
($P_SIM query).

4.10 Feedrate reduction with corner deceleration (FENDNORM, G62,
G621)
Function
With automatic corner deceleration the feed rate is reduced according to a bell curve before
reaching the corner. It is also possible to parameterize the extent of the tool behavior
relevant to machining via setting data. These are:
● Start and end of feed rate reduction
● Override with which the feed rate is reduced
● Detection of a relevant corner
Relevant corners are those whose inside angle is less than the corner parameterized in the
setting data.
Default value
