2. MACHINING MENU DESCRIPTIONS
– 161 –
J : PITCH
Input the machining allowance of one pass for rough cutting in the Z direction. Cut dividing the
machining allowance (V–Y) of the rough cutting by the pitch (J) into several passes. The machining
allowance (V–Y) is cut in one pass if not input.
Y : FINISHING
Input the machining allowance in the Z direction for finish cutting. This finish allowance is cut in one
pass. Finish cutting is not done if not input.
U : THICKNESS
Input the thickness of the work after facing. Despite that this input item is irrelevant to the actual
machining, it is used for drawing and checking the shape of the work. Be sure to input.
T : TOOL ID NO.
Input the tool ID number of the final tool to be used. Refer to the tool file for the corresponding tool
by pressing the TOOL DRCTRY soft key. Be sure to input.
Q : TOOL NAME
The tool corresponding to the value input to ”Tool ID No.” (T) is read from the tool file, and displayed.
B : PROCESS
There are two ”Rough cutting” and ”Finish cutting”
H : H OFFSET NO.
D : D OFFSET NO.
It is the offset number of the tool used. It is decided automatically by pressing the ”F.S. AUTO” soft
key. It is displayed reading the offset number, which corresponds to the value assigned to a tool
ID number (T), from a tool file.
M : COOLANT
It is the coolant selected by this machining menu. It is decided automatically using the ”F.S. AUTO”
soft key. The coolant set by the initial setting menu is displayed. After automatic setting, the coolant
can be changed as needed.
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 work material, the tool, and the tool di-
ameter, etc. It can be modified after the automatic decision if needed.
F : FEED RATE
It is the feed rate of the tool. It is decided automatically using the ”F.S. AUTO” soft key. It is calcu-
lated from the spindle speed (S) and the cutting condition file data. After automatic setting, the fee-
drate can be changed as needed.
E : CUT WIDTH (%)
Pressing the ”F.S. AUTO” soft key automatically determines the % of the cutting width. The actual
cutting width is calculated from the tool diameter and the % of the cutting width. After the automatic
setting, the cutting width % can be changed as needed.
K:Z–ESCAPE
It is decided automatically by pressing the ”F.S. AUTO” soft key. The actual clearance for cutting
is the following amount: Clearance = Clearance in the Z direction (K) + Pitch (J)
3) Explanation of movements
Facing is divided into the following two operations (B).
1 Rough cutting
2 Bottom finish cutting
Bottom finishing (2) above can be omitted according to the setting of input item, but the order of processes
(1) and (2) cannot be changed.
