The NC axis, spindle, and PLC axis are generically called the control axis.

The NC axis can be manually or automatically operated using a machining program. The PLC axis can be controlled using a sequence program.

The number of axes that is within the max. number of control axes, and that does not exceed the max. number given for the NC axis, spindle and PLC axis, can be used.



Machining programs stored in the memory of the CNC module are run.

MDI mode





MDI data stored in the memory of the CNC unit are executed.

4

High-speed program server mode

3

FTP high-speed program server mode





This function allows high-speed transfer of machining programs from the FTP server to the large-capacity buffer memory in CNC CPU via Ethernet to execute the program.

Input command

1

Data increment

1

Least command increment

The data increment handled in the controller includes the input setting increment and command increment. Each type is set with parameters.

Least command increment 1µm





Possible to command in increments of 0.001mm (linear axis) and 0.001° (rotary axis).

Least command increment 0.1µm





Possible to command in increments of 0.0001mm (linear axis) and 0.0001° (rotary axis).

2

Least control increment

The least control increment determines the CNC's internal operation accuracy.

Least control increment 0.01µm (10nm)





Possible to control in increments of 0.00001mm (linear axis) and 0.00001° (rotary axis).

Least control increment 0.001µm (1nm)





Possible to control in increments of 0.000001mm (linear axis) and 0.000001° (rotary axis).

3

Indexing increment





This function limits the command value for the rotary axis.

Positioning / Interpolation

1

Positioning

1

Positioning





This function carries out positioning at high speed using a rapid traverse rate with the travel command value given in the program.

2

Unidirectional positioning

—



The G code command always moves the tool to the final position in the direction determined by parameters.

2

Linear / Circular interpolation

1

Linear interpolation





Linear interpolation is a function that moves a tool linearly by the travel command value supplied in the program at the cutting feedrate designated by the F code.

2

Circular interpolation (Center / Radius designation)





This function moves a tool along a circular arc on the plane selected by the travel command value supplied in the program.

3

Helical interpolation





With this function, any two of three axes intersecting orthogonally are made to perform circular interpolation while the third axis performs linear interpolation in synchronization with the arc rotation. This control can be exercised to machine large-diameter screws or 3-dimensional cams.

4

Spiral / Conical interpolation

—



This function interpolates arcs where the start point and end point are not on the circumference of the same circle into spiral shapes.

5

Cylindrical interpolation





This function transfers the shape that is on the cylinder's side surface (shape yielded by the cylindrical coordinate system) onto a plane, and when the transferred shape is designated in the program in the form of plane coordinates, the shape is converted into a movement along the linear and rotary axes of the original cylinder coordinates, and the contours are controlled by means of the CNC unit during machining.

6

Polar coordinate interpolation





This function converts the commands programmed by the orthogonal coordinate axes into linear axis movements (tool movements) and rotary axis movements (workpiece rotation) to control the contours. It is useful for cutting linear cutouts on the outside diameter of the workpiece, grinding cam shafts, etc.

7

Milling interpolation



—

When a lathe with linear axes (X, Z axes) and rotary axis (C axis) serving as the control axes is to perform milling at a workpiece end face or in the longitudinal direction of the workpiece, this function uses the hypothetical axis Y, which is at right angles to both the X and Z axes, to enable the milling shape to be programmed as the X, Y and Z orthogonal coordinate system commands.

3

Curve interpolation

3

Spline interpolation (G05.1Q2 / G61.2)

—



This function automatically generates spline curves that smoothly pass through rows of dots designated by a fine-segment machining program, and performs interpolation for the paths along the curves. This enables high-speed and high-accuracy machining.

4

Feed

5

Thread cutting

1

Thread cutting (Lead / Thread number designation)





Thread cutting with a designated lead can be performed. Inch threads are cut by designating the number of threads per inch with the E address.

2

Variable lead thread cutting



—

By commanding the lead increment/decrement amount per thread rotation, variable lead thread cutting can be performed.

3

Synchronous tapping

* With digital I/F spindle

1

Synchronous tapping cycle





This function performs tapping through synchronized control of the spindle and servo axis. This eliminates the need for floating taps and enables tapping to be conducted at a highly accurate tapping depth.

2

Pecking tapping cycle





The load applied to the tool can be reduced by designating the depth of cut per pass and cutting the workpiece to the hole bottom with a multiple number of passes.

3

Deep-hole tapping cycle





In the deep-hole tapping, the load applied to the tool can be reduced by designating the depth of cut per pass and cutting the workpiece to the hole bottom with a multiple number of passes.

4

Multiple spindle synchronous tapping





This function enables two or more spindles to perform synchronous tapping at a time, thereby improving the tapping efficiency.

4

Chamfering



—

Chamfering can be enabled during the thread cutting cycle by using external signals.

6

Circular thread cutting

—

—

Circular thread in which the lead is in longitudinal direction can be cut.

8

High-speed synchronous tapping (OMR-DD)





The servo axis directly detects and compensates the spindle's delay in tracking by using the communication between drive units over the high-speed optical servo network. By minimizing the synchronization error, the accuracy of the synchronous tapping is increased.

11

Thread cutting override



—

The thread cutting feedrate can be changed by changing the spindle override depending on rough cutting, finish machining, etc.

12

Variable feed thread cutting



—

This function changes the cutting feedrate by the spindle override at the time of the thread cutting. The machining condition during thread cutting can be changed.
