12 Debugging the Part Program
The following functions help the testing, debugging of the part program:
– single block execution,
– dry run,
– locking possibilities and
– test run.
These functions are not operation modes, but conditions influencing the program execution in
automatic mode.
12.1 Single Block Execution
Single block execution can be
selected on OPERATOR’S
PANEL or POSITION screens.
After pressing the action menu
key,
F5
CONDITIONS action
menu must be selected, than
softkey SINGLE BLOCK needs
to be pressed.
If NCT machine control board is
used select the button.
Single block execution can be
done in automatic and manual
data input modes. The control
stops (STOP state) after the exe-
cution of each block.
An exception to that when thread cutting blocks G33 follow each other or suppression of
single block execution has been programmed by giving value #3003=1. The machining
continues with the START button .
12.2 Dry Run (All Feedrates at High Speed)
Switch DRY RUN can be reached on OPERATOR’S PANEL or POSITION screens. After
pressing the action menu key,
F5
CONDITIONS action menu must be selected, than softkey
DRY RUN needs to be pressed.
If NCT machine control board is used select the button.
When the switch is on all feeds move at high speed, fixed at parameter. It executes every
movement at feedrate interpreted in dimension per minute, independent of whether state G94
or G95 is programmed .
Generally the DRY RUN button can be activated only in one of the manual modes
provided the axes are in stopped state. For details turn to the machine tool builder for an
information material.
