Effect
With Cycle 800 ADAPT ROTARY COORDINATE SYSTEM, the
TNC aligns the workpiece coordinate system and orients the tool
correspondingly. Cycle 800 is effective until it is reset by Cycle 801,
or until Cycle 800 is defined again. Some cycle functions of Cycle
800 are additionally reset by other factors:
The mirroring of the tool data (Q498
REVERSE TOOL) is reset by
a
TOOL CALL.
The
ECCENTRIC TURNING Q535 function is reset at the end of
the program or due to cancelation of the program (internal stop).
Please note while programming:
The Cycle 800 ADAPT ROTARY COORDINATE
SYSTEM is machine-dependent. Refer to your
machine manual.
Software option 50 must be enabled
The tool must be clamped and measured in the
correct position.
You can only mirror the tool data (Q498
REVERSE
TOOL) when a turning tool is selected.
Check the orientation of the tool before machining.
Cycle 800 limits the maximum spindle speed during
eccentric turning. Therefore, program Cycle 801 to
reset Cycle 800, and reset the speed limitation with
FUNCTION TURNDATA SPIN SMAX.
If you use the settings 1: MOVE, 2: TURN
and 3: STAY in the parameter
Q530 INCLINED
MACHINING, the TNC activates the function M144
(see also User's Manual for Inclined Turning).
