3. WARNINGS AND CAUTIONS RELATED TO
PROGRAMMING
This section covers the major safety precautions related to
programming. Before attempting to perform programming, read the
supplied operator’s manual and programming manual carefully such
that you are fully familiar with their contents.
WARNING
1.
Coordinate system setting
If a coordinate system is established incorrectly, the
machine may behave unexpectedly as a result of the
program issuing an otherwise valid move command.
Such an unexpected operation may damage the tool, the
machine itself, the workpiece, or cause injury to the user.
2.
Positioning by nonlinear interpolation
When performing positioning by nonlinear interpolation
(positioning by nonlinear movement between the start
and end points), the tool path must be carefully confirmed
before performing programming.
Positioning involves rapid traverse. If the tool collides
with the workpiece, it may damage the tool, the machine
itself, the workpiece, or cause injury to the user.
3.
Function involving a rotation axis
When programming polar coordinate interpolation or
normal–direction (perpendicular) control, pay careful
attention to the speed of the rotation axis. Incorrect
programming may result in the rotation axis speed
becoming excessively high, such that centrifugal force
causes the chuck to lose its grip on the workpiece if the
latter is not mounted securely.
Such mishap is likely to damage the tool, the machine
itself, the workpiece, or cause injury to the user.
4.
Inch/metric conversion
Switching between inch and metric inputs does not
convert the measurement units of data such as the
workpiece origin offset, parameter, and current position.
Before starting the machine, therefore, determine which
measurement units are being used. Attempting to
perform an operation with invalid data specified may
damage the tool, the machine itself, the workpiece, or
cause injury to the user.
