16.1 Graphics
Application
In the program run modes of operation as well as in the Test Run
mode, the TNC graphically simulates the machining of the workpiece.
Using soft keys, select whether you desire:
Plan view
Projection in three planes
3-D view
The TNC graphic depicts the workpiece as if it were being machined
with a cylindrical end mill. If a tool table is active, you can also simulate
the machining operation with a spherical cutter. For this purpose,
enter R2 = R in the tool table.
The TNC will not show a graphic if
the current program has no valid blank form definition
no program is selected
Using the new 3-D graphics in the Test Run mode, you can
now also graphically display machining operations in the
tilted working plane as well as multi-sided machining
operations, provided that you have already simulated the
program in another view. You need at least the MC 422 B
hardware in order to use this function. In order to increase
the speed of the test graphics on older hardware versions,
bit 5 of MP7310 should be set to 1. This deactivates
functions which were implemented specifically for the 3-
D graphics.
The TNC graphic does not show a radius oversize DR that
has been programmed in the T block.
Graphic simulation for special applications
NC programs usually contain a tool call with a defined tool number,
which automatically determines the tool data for graphic simulation.
For special applications that do not require any tool data (e.g. laser
cutting, laser drilling or waterjet cutting), you can set Machine
Parameters 7315 to 7317 such that the TNC will run a graphic
simulation even if no tool data are activated. However, you always
need a tool call with the definition of the tool axis orientation (e.g. G17).
The tool number does not need to be entered.
