HEIDENHAIN TNC 426 B, TNC 430
Before programming, note the following:
From the current position, the TNC positions the tool in a
linear 3-D movement to the starting point . Pre-position
the tool in such a way that no collision between tool and
clamping devices can occur.
The TNC moves the tool with radius compensation R0 to
the programmed positions.
If required, use a center-cut end mill (ISO 1641).
ú
Starting point in 1st axis Q225 (absolute value):
Starting point coordinate of the surface to be
multipass-milled in the main axis of the working plane
ú
Starting point in 2nd axis Q226 (absolute value):
Starting point coordinate of the surface to be
multipass-milled in the secondary axis of the working
plane
ú
Starting point in 3rd axis Q227 (absolute value):
Starting point coordinate of the surface to be
multipass-milled in the tool axis
ú
