GENERAL WARNINGS AND CAUTIONS
The warning and caution below provide the precautions related to the
use of a CNC. It is essential that these precautions be observed by
users to ensure the safe operation of machines equipped with a CNC.
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 operation of the machine. Before
starting the machine, ensure that the settings are
correctly made, including the program values,
compensation, current position, and external signals.
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.
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 come under
unexpected load, 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.
