5. BALANCE CUT FAPT FUNCTION
(2–PATH LATHE ONLY)
PROGRAMMING AND
OPERATION BY SYMBOLIC FAPT
193
(1)In a process where system parameter No.707 is set to 1 (balance cutting
is possible), the system tries to select appropriate tools from both
heads.
Only when tools suited to this process are found in both heads, the
system designates the process as a balance cutting process. When two
or more tools are available, the system does not try to select the
optimum one. It searches the tooling file from the top and uses the one
it finds first.
(2)The cursor always stops at the DELAY AMOUNT prompt, so you can
change it to any desired value.
(3)When an appropriate tool is found only in either head, the concerned
process becomes a normal process, not a balance cutting process.
(4)When the X coordinate value of the start or end point of the cutting area
is 0, the concerned process cannot be a balance cutting process.
Suppose the following process is defined.
NO. KIND OF MACHINING HEAD NO.
1 ROUGH. OF CUT. 1, 2 (BALANCE CUT TYPE B)
2 FIN. OF CUT. 1, 2 (BALANCE CUT TYPE A)
3 GROOVING 1
4 THREADING 2
At this time, the following data appears on the process editing screen.
NO. (HEAD 1) (HEAD 2) SPINDLE SPEED
1 ROUGH. OF CUT. BALANCE CUT G97 V120 M03 (1)
2 FIN. OF CUT. BALANCE CUT G96 V115 M03 (1)
3 GROOVING G96 V90 M03 (1)
4 THREADING G96 V130 M03 (2)
The soft keys for moving up and down the process (“HEAD 1 UP”, etc.)
are not valid in the balance cutting process.
