Fanuc Series 15i/150i-MA (Programming) Operators Manual

SAFETY PRECAUTIONS B-63324EN/03
s-8
WARNING
7.Workpiece coordinate system shift
Manual intervention, machine lock, or mirror imaging may shift the workpiece coordinate system.
Before attempting to operate the machine under the control of a program, confirm the coordinate system
carefully.
If the machine is operated under the control of a program without making allowances for any shift in the
workpiece coordinate system, the machine may behave unexpectedly, possibly damaging the tool, the
machine itself, the workpiece, or causing injury to the operator.
8.Software operator’s panel and menu switches
Using the software operator’s panel and menu switches, in combination with the MDI panel, it is
possible to specify operations not supported by the machine operator’s panel, such as mode change,
override value change, and jog feed commands.
Note, however, that if the MDI panel keys are operated inadvertently, the machine may behave
unexpectedly, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the
user.
9.Manual intervention
If manual intervention is performed during programmed operation of the machine, the tool path may
vary when the machine is restarted. Before restarting the machine after manual intervention, therefore,
confirm the settings of the manual absolute switches, parameters, and absolute/incremental command
mode.
10.Feed hold, override, and single block
The feed hold, feedrate override, and single block functions can be disabled using custom macro system
variable #3004. Be careful when operating the machine in this case.
11.Dry run
Usually, a dry run is used to confirm the operation of the machine. During a dry run, the machine
operates at dry run speed, which differs from the corresponding programmed feedrate. Note that the dry
run speed may sometimes be higher than the programmed feed rate.
12.Cutter and tool nose radius compensation in MDI mode
Pay careful attention to a tool path specified by a command in MDI mode, because cutter or tool nose
radius compensation is not applied. When a command is entered from the MDI to interrupt in automatic
operation in cutter or tool nose radius compensation mode, pay particular attention to the tool path when
automatic operation is subsequently resumed. Refer to the descriptions of the corresponding functions
for details.
