Parameter Description
Insertion The following insertion modes can be selected – (only for ∇, ∇∇∇ or ∇∇∇ edge)
Predrilled: (only for G code)
•
With G0, the pocket center point is approached at the retraction level, and then,
from this position, the reference point brought forward by the safety clearance is
approached also with G0. The machining of the rectangular pocket is then
performed according to the selected insertion strategy, taking into account the
programmed blank dimensions.
Perpendicular: Insert vertically in center of pocket
•
The tool executes the calculated current depth infeed at the pocket center in a
single block. This setting can be used only if the cutter can cut across center or if
the pocket has been predrilled.
Helical: Insert along helical path
•
The cutter center point traverses along the helical path determined by the radius
and depth per revolution (helical path). If the depth for one infeed has been
reached, a full circle motion is executed to eliminate the inclined insertion path.
Oscillating: Insert with oscillation along center axis of rectangular pocket
•
The cutter center point oscillates back and forth 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.
FZ Depth infeed rate - (only for insertion, predrilled and perpendicular)
EP Maximum pitch of helix – (for helical insertion only)
ER Radius of helix – (for helical insertion only)
The radius cannot be any larger than the cutter radius; otherwise, material will remain.
EW Maximum insertion angle – (for insertion with oscillation only)
Complete machining
Solid machining •
(for roughing only)
The rectangular pocket is milled from the solid material.
Editing
•
The size of any existing smaller rectangular pocket or hole is increased in several
axes. You must program parameters AZ, W1 and L1 for this purpose.
AZ Depth of premachining – (for remachining only)
W1 Width of premachining – (for remachining only)
L1 Length of premachining – (for remachining only)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) – (for chamfer only)
