8. CAXIS FAPT FUNCTION B
510
NOTE
1 In case of FS 15TFB/TTFB, whether fixed cycle is used in
the generated NC data or not is determined by the MTF
parameter No.1304.
2 Initial value of SHIFT VALUE parameter is calculated as
follows by using tool data.
SH=[ (Cut Width DsTool Dia.DT) /2] /2
3 KEY IN AGAIN error occurd, if a value greater than (Cut
Width DsTool Dia.DT) /2 is entered in the parameter SH.
4 When fixed cycle is not used, whether the shift value SH is
programmed by using the address Q or I/K is determined by
the MTF parameter No.1342.
5 When fixed cycle is not used, the direction of the shift value
programmed as discrete NC data is determined by the MTF
parameter No.1342.
6 When the parameter DW is set to “1” , Dwell is programmed
at the bottom of the hole.Dwell Time is specified by the
system parameter No.395.
7 Retraction feed rate can switched between rapid traverse
feed rate and cutting feed rate, according to the MTF
parameter No.1342.
8 Retracting feed rate is calculated as follows.
FT x [Override value for retracing feedrate of C–AXIS
REAMING. (System Parameter No.396)]
The creating method of NC data is the same as that of CAXIS FAPT
FUNCTION.
Followings are the examples of NC data created for the new machining
features of CAXIS FAPT FUNCTION B.
