Set an FL feedrate at the fourth stage when the acceleration/deceleration time
constant for the spindle and drilling axis in rigid tapping is switched according to
the S command (bit 1 (TSC) of parameter No. 5605 is set to 1).
Parameter Nos. 5884 to 5894 are used to change the cutting feed
acceleration/deceleration time constant/FL feedrate on the hole machining axis in
rigid tapping according to the S command. These parameters set the time constant
(TCx)/FL feedrate (FLx) at each level and the spindle speed (Sx) to set levels.
The following show the relationship between the S command and FL feedrate, the
relationship between the S command and actual acceleration/deceleration time in
linear acceleration/deceleration, and the relationship between the S command and
actual acceleration/deceleration time in exponential acceleration/deceleration:
Spindle speed command S FL feedrate
S≤S1 FL1
S1<S≤S2 FL2
S2<S≤S3 FL3
S3<S FL4
