6. BALANCE CUT FAPT FUNCTION
(2–PATH LATHE ONLY)
OPERATION BY Symbolic FAPT
1 Set the same tool tip radius (RN) for both tools. The system
does not check the data other than the radius of the tool tip.
It is recommended to use tools having an identical tip figure.
If tools having different tip figures are used, the workpiece
may vibrated during actual machining and the tool tip may
interfere with the workpiece.
2 A negative value cannot be specified as the delay (DA). The
operator is prompted to specify the delay only when outer
surface roughing is selected. The system accepts 0 or a
positive integer. If 0 is specified, type A is selected. If a
positive integer is specified, type B is selected.
3 The turret numbers (TL) of the two tools must be different.
Specify turret 1 (TL = 1) for the first tool and turret 2 (TL =
2) for the second tool.
4 Select tools having an identical direction of spindle rotation
Unless the above instructions are observed, the system gives a warning
and prohibits display of the next screen.
(2)On the machining process list screen which is the first screen of Menu
No.4 (MACHINING DEFINITION), the balance cutting process is
represented by (B) following the T code.
PROC. 01 ROUGH. OF CUT. T0909 (B) X200. Z200.
When the process is not a balance cutting process, (1) or (2) is
displayed after the T code. (1) means cutting by head 1 while (2)
means cutting by head 2.
(3)In the balance cutting process, points whose X coordinate value is 0
must not be specified as the start or end point of the cutting area.
