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.
5. Constant surface speed control
When an axis subject to constant surface speed control approaches the origin of the workpiece coordinate system,
the spindle speed may become excessively high. Therefore, it is necessary to specify a maximum allowable speed.
Specifying the maximum allowable speed incorrectly may damage the tool, the machine itself, the workpiece, or
cause injury to the user.
6. Stroke check
After switching on the power, perform a manual reference position return as required. Stroke check is not possible
before manual reference position return is performed. Note that when stroke check is disabled, an alarm is not
issued even if a stroke limit is exceeded, possibly damaging the tool, the machine itself, the workpiece, or causing
injury to the user.
7. Absolute/incremental mode
If a program created with absolute values is run in incremental mode, or vice verse, the machine may behave
unexpectedly.
8. Plane selection
If an incorrect plane is specified for circular interpolation, helical interpolation, or a canned cycle, the machine
may behave unexpectedly. Refer to the descriptions of the respective functions for details.
