6. BALANCE CUT FAPT FUNCTION
(2PATH LATHE ONLY)
PROGRAMMING AND
OPERATION BY Symbolic FAPT
193
Balance cut can be used in the following processes.
Type A: (1) Roughing of outer diameter (not edges)
(2) Semifinishing of outer diameter (not edges)
(3) Finishing of outer diameter (not edges)
Type B: (1) Roughing of outer diameter
Type A and Type B are distinguished by the value that is set for “DELAY
AMOUNT” on the data screen. The delay amount determines how much
the head 2 tool lags behind the head 1 tool during machining. Type A is
selected by setting.
DELAY AMOUNT to 0 (no delay), and type B by setting it to a positive
value.
When type B is selected, the tool of turret 2 follows the tool of turret 1
while maintaining the delay specified in revolving speed. (The S code is
output to the program of turret 1.)
System parameter No.707 specifies which process should be a balance
cutting process and whether the machining type should initially be type
A or type B.

Bit 2 Finishing of outer diameter
0 : Not a balance cutting process
1 : Can be a balance cutting process when conditions are met
Bit 7 Roughing of outer diameter by balance cutting
0 : Sets the value of system parameter No.757 as the initial value of the
DELAY AMOUNT prompt on the tool data screen. This selects type
B.
1 : Sets 0 as the initial value of the DELAY AMOUNT prompt on the tool
data screen. This selects type A.

NOTE
If the MTF1051 and MTF1052 values differ from each other,
the balance cutting process cannot be performed (no
prompt is made for the balance cutting process during
machining definition).
