General information
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 NC block are moved simultaneously.
