General
Part program input
You create a part program by entering the workpiece dimensions.
Coordinates are programmed as absolute or relative (incremental)
values.
In general you program the coordinates of the end point of the contour
element.
The TNC automatically calculates the path of the electrode based on
the electrode data (length and radius) and the radius compensation.
Programmed machine axis movement
All axes programmed in a single NC block are moved simultaneously.
Paraxial movements
The electrode moves in path parallel to the programmed axis.
Number of axes programmed in the NC block: 1
Movement in the main planes
The electrode moves to the programmed position in a straight line or
circular arc in a plane.
Number of axes programmed in the NC block: 2
Movement of three machine axes (3-D movement)
The electrode moves in a straight line to the programmed position.
Number of axes programmed in the NC block: 3
Exception:
A helical path is created by combining circular movement with linear
movement.
