HEIDENHAIN CNC Pilot 4290 - Manual (Page 320)

6 TURN PLUS 308
P: ■ Contour milling: Milling depth – overwrites the ”depth” of
the contour definition
■ Deburring: Plunging depth of the tool – default: Chamfer
width (from ”deburring” machining attribute) + 1 mm
I: Maximum infeed – default: Milling in one infeed
L: Oversize – ”Shift” milling contour (”oversize G58” before the
milling cycle)
■ Effects of ”milling location, cutting direction and direction
of tool rotation”: See ” 4.11 Milling Cycles.”
■ Deburring: The chamfer width is defined as machining
attribute.
Area milling - Roughing/Finishing (G845/G846)
Roughs/finished figures or closed ”free contours” of the reference
planes:
■ FRONT
■ REAR SIDE
■ SURFACE
Parameters
J:
Retraction plane – default: return to starting position
■ Front/rear face: Retraction position in Z direction
■ Lateral surface: Retraction position in X direction (diameter)
Q: Machining direction (Q)
■ Toward the outside (Q=0): From the inside toward the
outside
■ Toward the inside (Q=1): From the outside toward the inside
H: Cutting direction
■ H=0: Up-cut milling
■ H=1: Climb milling
U: Overlap factor – range: 0 <= U <= 0.9;
0: No overlapping
V: Overshoot factor – has no effect for operations with the C
axis
P: Maximum infeed in the milling plane
I, K: Oversize in X, Z direction - is omitted for finishing
