4.1 DIN Programming
Introduction
The CNC PILOT supports both conventional DIN programming and
DIN PLUS programming.
„ Conventional DIN/ISO programming: You program the basic
contour with line segments, circular arcs and simple turning cycles.
For conventional DIN programming, the simple tool description is
sufficient.
„ “DIN PLUS” (ISO) programming: The geometrical description of
the workpiece and the machining process are separated. You first
program the geometry of the blank and finished part. Then you
machine the workpiece, using contour-related turning cycles. The
contour follow-up function can be activated for each machining
step, including individual paths of traverse and simple turning
cycles. The CNC PILOT optimizes the machining process as well as
the paths for approach and departure (no noncutting passes).
Depending on the type and complexity of your machining task, you can
use either simple DIN programming or DIN PLUS programming.
NC program sections: The CNC PILOT supports the division of the
NC program into individual program sections.
„ Program head (organizational data and setup information)
„ Tool list (turret table)
„ Chucking equipment table
„ Workpiece-blank definition
„ Description of machined part
„ Machining of workpiece
Parallel operation: While you are editing and testing programs, your
machine can execute another NC program.
