3.12.1 Definition of data
Coordinates of the machining point.
The coordinates are defined one by one. After placing the cursor on the coordinates of the axes to
be defined, the value is entered in one of the following ways.
• Entering the value manually. Key in the desired value and press [ENTER].
• Assign the current machine position.
Jog the axis with the handwheel or the JOG keys up to the desired point. Press [RECALL] so
the selected data assumes the value shown in the top right window and press [ENTER].
The top right window shows the tool position at all times.
Machining conditions in Z (Zs, Z, Zr, P, I, t, B).
The machining conditions are defined one by one.
• The Zs and Z values are defined as the coordinates of the machining point.
• To define the rest of the values (Zr, P, I, t, B), go to the corresponding window, key in the desired
value and press [ENTER].
Type of center punching.
• Defining the total machining depth (P).
• Defining the angle of the punch (

) and the diameter of the point (

).
To define the values (P,

,

), go to the corresponding window, key in the desired value and press
[ENTER].
Hole diameter (

Defines the diameter of the hole. To set this value, place the cursor in the corresponding window,
key in the desired value and press [ENTER].
If not programmed or programmed with a 0 value, the CNC will display the corresponding error
message.
Diameter of the pre-drilled hole (

K).
Starting with a hole previously drilled, this parameter defines the diameter of that hole. If not
programmed or programmed with a 0 value, it means that no hole has been previously drilled.
The tool must meet the following conditions:
• The tool radius must be smaller than J/2.
• The tool radius must be equal to or larger than (J-K)/4.
If these two conditions are not met, the CNC issues the corresponding error.
Helical penetration step (B).
It defines the helical penetration step (only for bore milling). To set this value, place the cursor in
the corresponding window, key in the desired value and press [ENTER].
If not programmed or programmed with a 0 value, the CNC will display the corresponding error
message.
Drilling direction.
Bottom milling.
To select the type of tapping, place the cursor over this icon and press the two-color key.
The type of center punching may be defined in two ways.
Defines the direction of the helical drilling path.
It defines whether the bottom of the hole (blind hole) is milled or not (through hole).
