12.3 Test run

Function

In the Test Run mode of operation you can simulate programs and
program sections to prevent programming 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

„

Optional Block Skip

„

Functions for graphic simulation

„

Measuring the machining time

„

Additional status display

The TNC cannot graphically simulate all traverse motions
actually performed by the machine. These include

„

traverse motions during tool change, if the machine
manufacturer defined them in a tool-change macro or via
the PLC,

„

positioning movements that the machine manufacturer
defined in an M-function macro,

„

positioning movements that the machine manufacturer
performs via the PLC, and

„

positioning movements that lead to a pallet change.

HEIDENHAIN therefore recommends proceeding with
caution for every new program, even when the program
test did not output any error message, and no visible
damage to the workpiece occurred.

Please note that the program test always assumes that
the tool is at safety clearance above the workpiece. At the
beginning of each program you should always traverse to
a position from which the TNC can position the tool for
machining without causing a collision!
