Operation Manual

HEIDENHAIN CNC PILOT 640 325
4.8 Milling cycles
ICP contour, axial
Select milling
Select ICP contour, axial
Depending on the parameters, the cycle mills a contour or roughs/
finishes a pocket on the face.
Cycle parameters (first input window)
X, Z Starting point
C Spindle angle (C-axis position)
Z1 Milling top edge (default: starting point Z)
P2 Milling depth
I Contour-parallel oversize
K Infeed-direction oversize
P Infeed depth (default: total depth of one infeed)
FZ Approach feed (infeed rate) (default: active feed rate)
E Reduced feed rate for circular elements (default: active
feed rate)
FK ICP contour number
G14 Tool change point (siehe Seite 140)
T Turret pocket number
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
Cycle parameters (second input window)
O Roughing or finishing—only for pocket milling
 0: Roughing
 1: Finishing
 2: Deburring
H Cutting direction
 0: Up-cut milling
 1: Climb milling
U Overlap factor (range: 0 < U < 1)
 U=0 or no input: contour milling
 U>0: Pocket milling—minimum overlap of milling paths
= U*milling diameter
JK Contour milling (input is evaluated only for contour milling)
 0: On the contour
 1: Within the contour
 2: Outside the contour
