1.1 GENERAL WARNINGS AND CAUTIONS
The following warnings and cautions describe the safety precautions
related to the use of CNC units. It is essential that these precautions be
observed by users to ensure the safe operation of machines equipped
with a CNC unit.
WARNING
1 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.
2 Never attempt to machine a workpiece without first
checking the programmed value, compensation
value, current position, and external signal settings.
Also, 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.
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.
