5. EXTENDED SUB
OPERATION BY Symbolic FAPT
Following three new features are added on the conventional sub cycle
(1)Japanese characters or European special characters can be used for
comment messages for arguments of sub cycles by entering the
specified character codes.
(2)Soft–keys are available in “SUB CYCLE” window under the
“MACHINING DEFINITION” window which are used to get
coordinate value of the current position of a specified axis and put it
in specified argument.
(3)Address word, the value of which is not defined in “SUB CYCLE”
window under the “MACHINING DEFINITION” window, can be
output in a part program with the value of “0”.
In “SUB CYCLE” window under the “MACHINING DEFINITION”
window, a coordinate value of the current machine position can be
acquired by the following procedure.
D Select a sub cycle name, to be included in the output part program,
from sub cycle menu.
D Soft–keys, which are used to acquire the current machine position of
the primary turret (POS.1 MACHIN) or the secondary turret (POS.2
MACHIN), become active in the “SUB CYCLE” window.
D These soft–keys can be activated or inactivated according to the state
of the system parameter No. 800 #1. But “Pos.2 MACHIN” soft–key
remains inactive in case of 1–path lathe.
D The number of the axis of which the position is to be acquired is
specified by the system parameter No.713 and 714.
D Select an argument to set data by putting the cursor on it, and press one
of the soft–keys after moving appropriate axis to the position which
you want to acquire, then the coordinate value of the machine position
is acquired and set in the argument.
Whether an address word, the value of which is not defined in “SUB
CYCLE” window under the “MACHINING DEFINITION” window, is
output in a part program or not, can be controlled by the system parameter
No.800 #4. When the parameter is set to output the address word, the
address word is output with the value of “0”.
