2. MACHINING MENU DESCRIPTIONS
– 111 –
J : PITCH
Input the cutting allowance for the Z direction for each roughing pass. The cutting allowance for
roughing (U – V) is divided by pitch (J) and multiple passes are made. If no pitch is input, the cutting
allowance for roughing (U – V) is made with a single pass.
V : FINISHING
Input the cutting allowance for the Z direction for finishing. This cutting allowance is made by a
single pass. Finishing is executed only when this value is input.
T : TOOL ID NO.
Input the tool ID number used in the NC program. This value must always be specified.
Q : TOOL NAME
The tool name corresponding to a value input in TOOL ID NO. (T) is read from the tool file and dis-
played.
B : MACHINING PROCESS
There are two machining processes: [ROUGH MACHINING] and [FINISH MACHINING].
H : H OFFSET NO.
It is decided automatically by pressing the [F.S. AUTO] soft key. The H offset No. is displayed after
reading the input value of a tool ID number (T) from a tool file.
M : COOLANT
It is the coolant used with this machining menu. It is automatically decided using the [F.S.AUTO]
soft key. The coolant set by the initial setting menu is displayed. After automatic decision, this value
can be altered if necessary.
S : SPINDLE SPEED
It is the speed of the tool spindle. It is decided automatically using the [F.S.AUTO] soft key. It is
calculated from the cutting condition file data based on the workpiece material, tool name, tool di-
ameter, and so forth. After automatic decision, this value can be altered if necessary.
F : FEED RATE
It is the feedrate of the tool. It is decided automatically using by the [F.S.AUTO] soft key.
It is calculated from SPINDLE SPEED (S) and the cutting condition file data. After automatic deci-
sion, this value can be altered if necessary.

ZI01 (Initial setting) Q_M_I···;
ZF01 (Facing prepare) YB_Z_U···;
ZF02 (Square (uni–dir)) X_Y_U···;
ZE99 (End of machining);
ZI04 (NC language preparation) YB_R_Z···;
ZN01 (Positioning) G00X_Y_···;
ZN02 (Line) G01X_Y_···;
NC statement program
ZE99 (End of machining);
ZI02 (End of program) C_T_;
NOTE 1 When All Copy or Group Copy is selected, the workpiece coordinate system cannot be changed
in the NC statement program.
NOTE 2 When Group Copy is enabled, the coordinate plane (G17, G18, G19) cannot be changed in the
NC statement program.
NOTE 3 Be sure to insert ZE99 (end of machining) at the end of an NC statement.
