The TNC and the machine tool must be specially prepared by
the machine tool builder for the use of the 28 CYLINDER
SURFACE
Cycle.
„ The workpiece must be set up concentrically on the rotary
table.
„ The tool axis must be perpendicular to the axis of the rotary
table.
„
Cycle 14 CONTOUR GEOMETRY can have only one label
number.
„ A subprogram can hold approx. 2048 line segments. C
