Measuring the machining time
Program run modes of operation
The timer counts and displays the time from program start to
program end. The timer stops whenever machining is interrupted.
TEST RUN
The timer displays the approximate time which the TNC calculates
from the duration of tool movements. The time calculated by the
TNC cannot be used for calculating the production time because
the TNC does not account for the duration of machine-dependent
interruptions, such as tool change.
To activate the stopwatch function
Shift the soft-key rows until the TNC displays the following soft keys
with the stopwatch functions:
Stopwatch functions Soft key
Store displayed time
Display the sum of stored time
and displayed time

11.2 Test run
In the TEST RUN mode of operation you can simulate programs and
program sections to prevent errors from occurring during program
run. The TNC checks the programs for the following:
■ Geometrical incompatibilities
■ Missing data
■ Impossible jumps
■ Violation of the machine's working space
The following functions are also available:
■ Blockwise test run
■ Interrupt test at any block
■ Functions for graphic simulation
■ Additional status display
