Programming technology functions (cycles)
10.4 Milling
Parameter Description
ER Radius of helix – (for helical insertion only)
(only for G code) The radius cannot be any larger than the milling cutter radius; otherwise, material will
remain.
EW Maximum insertion angle – (for insertion with oscillation only)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
Note
Predrilling position
The position at which inserting takes place if "predrilled" is selected is the same position that
you select if the reference point "inside left" is specified. In the case of a groove without an angle
of rotation, the predrilling position is the center point of the left rounding radius of the groove.
When calling the cycle on a position circle, the predrilling position is always the center point of
the rounding radius that is closer to the center of the circle.
