OPERATION

Even if the machine is not actually operated, the machining tool path can
be displayed.
When this function is used, it is not necessary to operate the machine.
However, the requirements for starting the actual NC operation of the
machine must be met by the following: selecting the MEM mode with
the mode switch on the machine operator’s panel and releasing the start
lock and interlock.
WARNING
Even after machining simulation has made sure that the programmed tool path and machining
operation are correct, if actually used data such as the tool offset and work shift amount is
incorrect, the tool may bump against the workpiece and/or machine (including the chuck and
tailstock), possibly causing damage to the tool and/or machine, and even injuries.
For this reason, before starting actual machining, make sure that the tool will not bump against
the workpiece or machine, for example, by starting the machining program with sufficiently low
feedrate without attaching a workpiece to the machine.
WARNING
Machining simulation may cause data such as a work shift amount, tool tip radius/wear
compensation value, virtual tool tip direction data, tool exchange position (second reference
position data), chuck barrier data (second stored–stroke limit data), and chuck/tailstock barrier
data (only when the relevant option is available) to be changed according to the machining
program subjected to machining simulation.
If another program (conversational machining program or a machining program in the form of NC
statements) runs under this condition, the tool may bump against the workpiece and/or machine,
possibly causing damage to the tool and/or machine, and even injuries.
WARNING
In some cases, machining simulation may not cause data such as a work shift amount, tool tip
radius/wear compensation value, virtual tool tip direction data, tool exchange position (second
reference position data), chuck barrier data (second stored–stroke limit data), and chuck/tailstock
barrier data (only when the relevant option is available) to be changed according to parameter
settings. For details, refer to the applicable manual supplied by respective the machine tool
builders.
Even in such cases, before running another program (conversational machining program or a
machining program in the form of NC statements), make sure that the data described above is
correct.
If the data is incorrect, the tool may bump against the workpiece and/or machine, possibly causing
damage to the tool and/or machine, and even injuries.
