Meanings of columns in the "Scratch" window:
· "Offset": Current value of offset to be determined. The coarse
offset is displayed; the fine offset is taken into account and remains
valid.
· "Set position": Input of subsequent setpoint position for scratched
edge.
· "Approach direction": selection fields for positive/negative
approach direction
2. Use the cursor to select the first axis to be moved in the "Scratch"
display.
Selected axes are automatically marked in parallel in the actual
value window.
3. Move the axis up to the workpiece, enter the chosen setpoint
position (e.g. "0") and press the "Input" key. The offset is then
calculated.
Repeat the process for other axes.
4. Press "OK" to transfer all values to the selected WO. The offset is
always calculated in relation to the current work (WCS).
5. To ensure that allowance is made in the tool geometry (or the tool
base dimension), position the cursor in the "Approach direction"
column on the axis to be altered and press the "Toggle key" so that
the desired approach direction is visible.
