The parameters Q429 COOLANT ON and Q430 COOLANT OFF
in Cycle 241 SINGLE-LIP D.H.DRLNG (ISO: G241, option19) have
been enhanced. You can define a path for a user macro.
An input value of 2 has been added to parameter Q575 INFEED
STRATEGY in Cycle 272 OCM ROUGHING (ISO: G272, option167).
With this input option, the control calculates the machining
sequence so that the tooth length of the tool is used to its full
extent.
Certain cycles permit you to enter tolerances. In the following
cycles, you can define dimensions, tolerances according to DIN
EN ISO 286-2 or general tolerances according to DIN ISO 2768-1:
Cycle 208 BORE MILLING (ISO: G208, option19)
Cycle 1271 OCM RECTANGLE (ISO: G1271, option167)
Cycle 1272 OCM CIRCLE (ISO: G1272, option167)
Cycle 1273 OCM SLOT / RIDGE (ISO: G1273, option167)
Cycle 1278 OCM POLYGON (ISO: G1278, option167)

Cycles for Workpieces and Tools
The unit of measurement of the main program can be seen in the
header of the log file of the Probing Cycles 14xx and 42x
If a basic rotation is active in the workpiece preset, the control
shows an error message during execution of the Cycles 451
MEASURE KINEMATICS (ISO: G451, option48), 452, PRESET
COMPENSATION (ISO: G452, option48). The control resets the
basic rotation to 0 during continuation of the program.
The parameter Q523 TT-POSITION has been added to Cycle
484 CALIBRATE IR TT (ISO: G484). This parameter allows you
to define the position of the tool touch probe and, if desired, to
transfer the position to the machine parameter centerPos after
calibration.
The Cycles 1420 PROBING IN PLANE (ISO: G1420), 1410
PROBING ON EDGE (ISO: G1410), 1411 PROBING TWO CIRCLES
(ISO: G1411) have been enhanced:
In these cycles, you can define tolerances according to DIN
EN ISO 286-2 or general tolerances according to DIN ISO
2768-1.
If you defined the value 2 in parameter Q1125 CLEAR.
HEIGHT MODE, the control positions the touch probe at
rapid traverse FMAX from the touch probe table to the set-up
clearance.
