CNC PILOT 4290, Software and Functions
This manual describes functions that are available in the CNC
PILOT 4290 with NC software number 625 (Release 7.1). For
programming the B and Y axes, please refer to the User's Manual
“CNC PILOT 4290 with B and Y Axes”. It is not described in this
manual.
The machine manufacturer adapts the features offered by the control
to the capabilities of the specific lathe by setting machine parameters.
Therefore, some of the functions described in this manual may not be
among the features provided by the CNC PILOT on your machine tool.
CNC PILOT functions that may not be available on your machine
include:
Machining with the C Axis
Machining with the B axis
Machining with the Y-axis
Full-surface machining
Tool monitoring
Graphically supported interactive contour definition
Automatic or graphically supported interactive DIN PLUS program
generation
Please contact your machine manufacturer for detailed information on
the features that are supported by your machine tool.
Many machine manufacturers and HEIDENHAIN offer programming
courses for the CNC PILOT controls. We recommend these courses
as an effective way of improving your programming skill and sharing
information and ideas with other CNC PILOT users.
HEIDENHAIN also offers the PC software DataPilot 4290, which is
designed for use with the CNC PILOT 4290. The DataPilot is suitable
for both shop-floor programming as well as off-location program
creation and testing. It is also ideal for training purposes.
Intended place of operation
The CNC PILOT 4290 complies with the limits for a Class A device in
accordance with the specifications in EN 55022, and is intended for
use primarily in industrially-zoned areas.

Introduction and Fundamentals
HEIDENHAIN CNC PILOT 4290 29
1.1 The CNC PILOT
The CNC PILOT is a contouring control designed for complex lathes
and turning centers. In addition to turning operations, the control can
also perform milling, drilling and boring operations. The C, Y and B
axes enable you to drill and mill on the front and rear faces, the lateral
surface and oblique planes. And as always, the CNC PILOT supports
full-surface machining with dual-spindles.
The CNC PILOT controls up to six slides, four spindles, two C axes,
one B axis and a pocket-oriented tool magazine. The control can
machine up to four workpieces simultaneously.
1.1 The CNC PILOT
Programming
Depending on the type and complexity of the parts to be machined
and your organization, you can choose the type of programming best
suited to your tasks.
In TURN PLUS you describe the contour of the blank and finished part
using interactive graphics. Then you call the automatic working plan
generation (AWG), and the NC program will be generated fully
automatically on a keystroke. An alternative is the interactive working
plan generation (IWG). When using the IWG, you determine the
sequence of machining and other technical details.
Every working step is shown in the control graphics and can be
corrected immediately. The result of program creation with TURN
PLUS is a structured DIN PLUS program.
TURN PLUS minimizes the number of entries required, but it requires
that the the tool data and cutting data has already been entered.
If TURN PLUS fails to create the optimal NC program for
technologically sophisticated machining operations, or if you
primarily want to reduce the machining time, write the NC program
with DIN PLUS.
In DIN PLUS you first describe the contour of the workpiece blank and
finished part. The “simplified geometry programming” calculates
nondimensioned coordinates if, for example, the drawing is not
dimensioned for conventional NC. Then you write the NC program
using powerful fixed cycles.
Both TURN PLUS and DIN PLUS support a C or Y axis and full-surface
machining. DIN PLUS cycles are available for working with the B axis.
As an alternative, you can machine your workpiece in DIN PLUS with
linear and circular movements and simple turning cycles, as you are
accustomed to in conventional DIN programming.
