General information
Part program input
You create a part program by entering the workpiece dimensions.
Coordinates are programmed as absolute values (G90) or relative values
(G91).
In general, you program the coordinates of the end point of the contour
element.
The TNC automatically calculates the path of the tool based on 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
The tool moves in a path parallel to the programmed axis.
Number of axes programmed in the block: 1
Movement in the main planes
The tool moves to the programmed position on a straight line or circular
arc in a plane.
Number of axes programmed in the block: 2
