General information
TNC 360
Part program input
To create a part program you enter the dimensional information given on
the workpiece drawing. The workpiece coordinates are entered as relative
or absolute values.
You normally program a contour element by entering its end point.
The TNC automatically calculates the tool path from the tool data and the
radius compensation.
Machine axis movement under program control
All axes programmed in a single block are moved simultaneously.
Paraxial movement
Paraxial movement means that the tool path is parallel to the programmed
axis.
Number of axes programmed in the NC block: 1
Movement in the main planes
With this type of movement the tool moves to the programmed position
on a straight line or circular arc in a “working plane.”
Number of axes programmed in the NC block: 2
