Description
Machining plane:
1)
G17 (XY)
Retraction plane (abs)
Normally, reference point Z0 and retraction plane RP have different values. The
cycle assumes that the retraction plane is in front of the reference point.
Safety clearance (inc)
Acts in relation to the reference point. The direction in which the safety clearance
is active is automatically determined by the cycle.
Feedrate
Depth infeed rate
Single 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:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z
Elongated hole length
Angle of rotation
Elongated hole depth (abs) or depth in relation to Z0 (inc)
Maximum depth infeed
The following insertion modes can be selected:
Centered: Insert vertically in longitudinal groove center:
•
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.
Oscillation: Insert with oscillation along center axis of longitudinal groove:
•
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 remove the slope caused by insertion.
