5. FEED FUNCTIONS
NC FUNCTION
53
Generally, the CNC does not zero the feedrate at the interface of two
blocks during cutting feed.
Because of this, a corner of a tool path may be rounded.
This part causes the corner of the tool
path to be rounded.

If the error detect signal is used, it is possible to specify that
a block not be started until the acceleration/deceleration
of the previous block has been completed.
NOTE
If the error detect signal is on, a cutting block is not executed
until the acceleration/deceleration of the previous cutting
block has been completed.
This function alone cannot prevent corner rounding due to
delay caused by the servo motor, however.
To prevent corner rounding due to delay caused by the
servo motor, use the in–position check function together
with this function.
