2. MACHINING MENU DESCRIPTIONS
– 304 –
(c) When the machining process (B) is chamfer
Refer to ”(d) Finish machining” of ”(3) Explanation of operation” of ”Contour pocketing prepa-
ration (ZP09).”
(d) When the machining process (B) is hole machining or hole (peck)
Refer to ”Explanation of operation” of ”Drilling (ZH01)” and ”Peck drilling (ZH02).”
NOTE 1 Because of the restrictions on the contour figure or the size of the work area for calculation
(1MB), an alarm may be issued. If this occurs, separate the input figure, i.e., separate the defini-
tion of the figure into multiple definitions. (Divide the machining area into multiple areas.)
NOTE 2 In pocketing figures and island figures, the side cannot be tapered.
NOTE 3 If the tool interferes with the pocketing figure or island figures during side finish machining, a tool
path in which the interference is avoided is not created.
NOTE 4 Foreground operation with this function and background drawing cannot be used at the same
time. If an attempt is made, an alarm ”not enough memory” is issued.
NOTE 5 To use this function, the following parameters are required in addition to the option:
9476
Address of the argument representing the input item ”CUTTING DRCT.” on the
contour pocketing preparation screen
Enter the decimal equivalents of ASCII codes.
To use FANUC standard macros, set 85 (U).
9477 Value of the argument representing the input data [SPIRAL] on the
contour pocketing preparation screen
To use FANUC standard macros, set 3 (SPIRAL).
NOTE 6 This function calculates an optimum tool path before executing contour pocketing. For compli-
cated figures profile, therefore, much time may be required for the calculation. When drawing
is in progress, a message ”Calculating the tool path” is displayed. If the tool path is not to be
calculated during execution, execute a program converted into NC statements.
