General Warnings and Cautions
WARNING
1. Never attempt to machine a workpiece without first checking the
operation of the machine. Before starting a production run, ensure
that the machine is operating correctly by performing a trial run
using, for example, the single block, feedrate override, or machine
lock function, or by operating the machine with neither a tool nor
workpiece mounted. Failure to confirm the correct operation of the
machine may result in the machine behaving unexpectedly,
possibly causing damage to the workpiece and/or machine itself,
or injury to the user.
2. Before operating the machine, thoroughly check the entered data.
Operating the machine with incorrectly specified data may result in
the machine behaving unexpectedly, possibly causing damage to
the workpiece and/or machine itself, or injury to the user.
3. Ensure that the specified feedrate is appropriate for the intended
operation. Generally, for each machine, there is a maximum
allowable feedrate. The appropriate feedrate varies with the
intended operation. Refer to the manual provided with the
machine to determine the maximum allowable feedrate. If a
machine is run at other than the correct speed, it may behave
unexpectedly, possibly causing damage to the workpiece and/or
machine itself, or injury to the user.
4. When using a tool compensation function, thoroughly check the
direction and amount of compensation.
Operating the machine with incorrectly specified data may result in
the machine behaving unexpectedly, possibly causing damage to
the workpiece and/or machine itself, or injury to the user.
5. The parameters for the CNC and PMC are factory-set. Usually,
there is no need to change them. When, however, there is no
alternative other than to change a parameter, ensure that you fully
understand the function of the parameter before making any
change.
Failure to set a parameter correctly may result in the machine
behaving unexpectedly, possibly causing damage to the workpiece
and/or machine itself, or injury to the user.
