HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 44)

Y Axis 44
4 Y Axis in TURN PLUS
TURN PLUS supports the definition of milling contours and holes
and creates working plans for milling and drilling with the Y axis.
Milling contours/holes
Milling contours are figures (such as slots, rectangles, etc.), linear/
circular patterns or user-definable ”free contours.” Holes are
considered to be individual holes or hole patterns.
Milling and drilling
TURN PLUS supports milling, drilling and boring in the IWG
(Interactive Working plan Generation) and AWG (Automatic
Working plan Generation).

4.1 TURN PLUS Milling Contours
Before you enter a milling contour, you must define the workpiece
blank and the turning contour.
”Free contours”
With the elements ”line” and ”arc” you can define any contour.
You simply define the ”starting point of contour,” describe the
contour, and then define the depth of the pocket/contour.
Enter the milling contours
Select the ”pattern” or ”figure.”
Define the ”workpiece surface” to be machined (the ”window
selection” dialog box appears only when a pattern or figure is
selected for the first time. The workpiece surface remains
selected.)
Select the workpiece surface:
■ Y front face
■ Y rear side
■ Y lateral surface
Select the ”milling plane” (reference plane in the Z direction or
reference diameter) – up/down cursor keys or left/right cursor
keys and confirm with ENTER.
Check the ”reference data” – add the ”spindle angle.”
Pattern/Figure parameter, or ”free contour.”
”Free contours”:
End the element selection (ESC key).
End the contour definition (ESC key).
Enter the ”depth” (”pocket/contour” dialog box).
Check the programmed contours in the control graphic.
Before you use the AWG , assign machining
attributes to the contour (see User's Manual,
section ”6.5.3 Machining Attributes”). With the
familiar methods offered by TURN PLUS, you can
determine the sequence of milling operations, the
use of tools, etc.
Note during data input
In hierarchically designed milling contours (pocket
in pocket, holes/figures on a surface, etc.), you can
select among all contours of the hierarchy on a
”workpiece surface” by pressing the up/down
cursor keys. With the right/left cursor key you can
select among the milling contours of a hierarchy
level.
■ Before you enter a ”free contour”, you
must define it under ”workpiece
surface.” To do so, select any figure or a
pattern and interrupt this dialog after the
selection of ”workpiece surface.”
■ You can change the ”workpiece
surface” by activating the ”main view”
(XZ window) before selecting the
pattern/figure.
■ You can change the ”active window”
by pressing the ”Page up/Page down”
key.
