Parameter Description
PL Machining plane
RP Retraction plane (abs)
SC Safety clearance (inc)
F Feedrate
Machining type
Plane-by-plane
•
The tool is inserted to infeed depth in the pocket center.
Note: This setting can be used only if the cutter can cut across center.
Oscillating
•
Insert with oscillation along center axis of longitudinal slot:
The cutter center point oscillates along a linear path until it reaches the depth
infeed. When the depth has been reached, the path is traversed again without
depth infeed in order to eliminate the inclined insertion path.
Reference point Position of the reference point:
Machining
Single position
•
position
An elongated hole is machined at the programmed position (X0, Y0, Z0).
Position pattern
•
Several elongated holes are machined in the programmed position pattern (e.g.
pitch circle, grid, line).
The positions refer to the reference point:
X0 Reference point X – (for single position only)
Y0 Reference point Y – (for single position only)
Z0 Reference point Z
L Elongated hole length
α0 Angle of rotation
Z1 Elongated hole depth (abs) or depth in relation to Z0 (inc)
DZ Maximum depth infeed
FZ Depth infeed rate
