Introduction
1.4 Graphics and Status Display
In the PROGRAMMING AND EDITING mode of operation the TNC
shows a two-dimensional graphic of the programmed contour. During FK
free contour programming the graphics are interactive.
In the TEST RUN operating mode the TNC graphically simulates work-
piece machining in:
l
Plan view
l
Projection in three planes
l
3Dview
The display mode is selected via soft keys.
The TNC graphic depicts the workpiece as if it were being machined by
a cylindrical end mill. The graphics cannot show rotary axis movements.
With the fast internal image generation option, the TNC calculates the
contour and displays a graphic only of the completed part.
Plan view
In this mode, contour height is shown by image
brightness. The deeper the contour, the darker the
image.
Number of depth levels: 7
Plan view is the fastest of the three display modes.
