If the final machining allowance ≥ tool diameter, the pocket will not necessarily be machined completely. The message
"Caution: final machining allowance ≥ tool diameter" appears; the cycle, however, is continued.
_FALD (finishing allowance at the base)
When roughing, a separate finishing allowance is taken into account at the base.
_FFD and _FFP1 (feedrate for depth and surface)
The feedrate _FFD is effective when inserting into the material.
The feedrate _FFP1 is active for all movements in the plane traversed at feedrate when machining.
_CDIR (milling direction)
Use this parameter to specify the machining direction for the pocket.
Using the parameter _CDIR, the milling direction can be programmed directly with "2 for G2" and "3 for G3", or alternatively
with "synchronous milling" or "conventional milling".
Synchronized operation or reverse rotation are determined internally in the cycle via the direction of rotation of the spindle
activated prior to calling the cycle.
M4 → G2 M4 → G3
Use the parameter VARI to define the machining type.
Possible values are:
Units digit:
● 1=roughing
● 2=finishing
Tens digit (infeed):
● 0=vertically to pocket center with G0
● 1=vertically to pocket center with G1
● 2=along a helical path
● 3=oscillating to pocket length axis
If a different value is programmed for the parameter _VARI, the cycle is aborted after output of alarm 61002 "Machining type
defined incorrectly".
_MIDA (max. infeed width)
Use this parameter to define the maximum infeed width when solid machining in a plane. Analogously to the known
calculation method for the infeed depth (equal distribution of the total depth with maximum possible value) the width is
distributed equally, maximally with the value programmed under _MIDA.
If this parameter is not programmed or has value 0, the cycle will internally use 80% of the milling tool diameter as the
maximum infeed width.
Applies if the calculated width infeed from edge machining is recalculated when reaching the full pocket in the depth;
otherwise the width infeed calculated at the beginning is kept for the whole cycle.
_AP1, _AP2, _AD (blank dimensions)
Use the parameters _AP1, _AP2 and _AD to define the blank dimensions (incremental) of the pocket in the plane and in the
depth.
Use the _RAD1 parameter to define the radius of the helical path (relative to the tool center point path) or the maximum
insertion angle for the reciprocating motion.
