Determining the electrode length with a zero electrode
Sign of the electrode length L:
To determine the length:
8 Move zero electrode to the reference position in electrode axis
(such as workpiece surface with Z = 0).
8 If necessary, set datum in electrode axis to zero.
8 Insert electrode.
8 Move electrode to the same reference position as zero electrode.
8 The compensation value for length L of the electrode is displayed.
8 Write down the value and enter it later, or transfer the value with the
actual position capture function.
Entering electrode data into a program
For each electrode the electrode data can be entered once in the part
program:
„ Electrode number
„ Electrode length compensation value L
„
Electrode radius R
To enter the electrode data into a program block
The number, length and radius of a specific electrode is defined in the
TOOL DEF block of the part program.
8 To select tool definition, press the TOOL DEF key.
8 Tool number : Assign a number to the electrode
8 Tool length : Compensation value for the tool length
8 Tool radius : Compensation value for the tool radius
Example
L>L0: The tool is longer than the zero tool
L The tool is shorter than the zero tool
Z = 0
L = 0 L –
L +
T N T 1 T 2
„ The electrode length L can be transferred directly into
the electrode definition with the actual position capture
function (see ”Actual Position Capture” on page 84).
„
Cycle 3 TOOL DEF (see ”Cycle 3 TOOL DEF” on page
135) deletes the tool length from the TOOL DEF(inition)!
