M700V Series
All operations from program values to servo commands are
done in nanometer units. Interpolation is at the nano-unit
level even when program commands are in micrometer
units.
SSS control is now available for the most basic function of five-
axis simultaneous interpolation control, tool center point control.
It compensates uneven paths output from CAM to smoothly
joint the tool center points’ path. In addition, rotary axis pre-filter
is available to move the rotary axis smoothly, which achieves
high-grade cutting in five-axis simultaneous machining.
Unlike conventional control, which simply matches the motor
path to the commands, OMR control calculates the ma-
chine's status based on a model and applies correction to
motor control in order to match not the motor position, but
the machine tool position to the commands.
High-accuracy machining is realized by controlling each axis
so that the tool center point moves linearly at a commanded
feed rate even if the rotary axis moves in linear interpolation.

Control Axis Superimposition
(Lathe System)
Guide Bushing Spindle Synchronization Control
(Lathe System)
This function is for a machine with a spindle motor to rotate a
guide bushing: This function allows the guide bushing
spindle motor (G/B spindle) to synchronize with a reference
spindle motor (Reference spindle).
The position error compensation function reduces the
spindle’s vibration due to the workpiece’s torsion, and the
motor’s overload.
This function enables machining using a certain part system
simultaneously with that of another part system by
superimposing their movements.
This is effective when machining in multiple part systems is
ex-ecuted simultaneously. It allows for an axis to shift its
coordi-nate system relative to the system using the axis.
