4. From this screen select the parameter that it is desired to change by
pressing the up or down cursor keys. The selected parameter is
shown in reverse video.
5. There are two options:
To replace the current value of the parameter with a new value,
key in the new value on the input line of the CRT and press the
{REPLCE VALUE} softkey. The new value replaces the old
value.
To add an amount to the current value of the parameter, key in the
amount to add to the current parameter value on the input line of
the CRT and press the {ADD TO VALUE} softkey. The value just
keyed in is then added to the old value for the selected parameter.
6. To leave the Drilling Cycle Parameter screen, there are two options:
To save the changes just made to the parameters and leave the

The following are example programs and an illustration of G83, deep hole
drilling cycle. Example 27.2 is in incremental mode; Example 27.3 is in
absolute. Figure 26.17 illustrates the result for both programs individually.
