Programming
2.2.7 Cs Contour Control Funciton
Controlling a spindle speed is called as the spindle rotation control (the spindle rotates by the
speed command), and controlling the spindle position is called as the spindle contour control (the
spindle rotates by the movement command). The function of the spindle contour control is that of Cs
contour control. Being the servo feed axis, the spindle rotates and orients by the position movement
command, and executes the interpolation with other feed axes to machine the contour curve.
2.2.8 Spindle Positioning Function
In the turning machining, the spindle rotates at one certain speed, therefore, the workpiece
installed on the spindle revolved and machined. In this case, the spindle control state is called
“Spindle Rotation Mode”. Compare to the others, moves one angle for the spindle, so that the
workpiece installed on the spindle positions at one angle, which is regarded as “Spindle Positioning
Function”. In this case, the controllable state of the spindle is called “Spindle Positioning Mode”.
Generally, the spindle positioning axis is mechanically clamped to use after the positioning operation
is performed, and therefore, the relation operations between the spindle clamping and releasing may
be performed before/after the positioning.
The spindle positioning function can be devided into 3 steps based upon the operation:
z Release the spindle rotation method, shift to the spindle positioning mode
Shift the spindle to its positioning method by executing the specific M code (Parameter
setting), and then set up a reference position.
z The positioning spindle operation in the spindle positioning method.
Spindle positioning can be performed the position of arbitrary angle by axis address, which
can be used the absolute and relative commands. It is better not to perform with the shared
block other than the G00 or G50 command.
For example, suppose the controllable axis is C axis:
G00 C45.000
G00 H-60.000
z Release the spindle positioning method, shift to the operation of the spindle rotation
method.
Shift the spindle to the spindle rotation method by performing the specific M code (Parameter
Setting).
Compare the spindle positioning function with the Cs axis contour controllable function,
regardless of the linkage interpolation with other axes; generally, the mechanical equipment clamping
can be used when the position is completed.
Especially note, the spindle positioning function and Cs axis contour controllable function can not
be simultaneously used.
2.3 Tool Function
2.3.1 Tool Control
T functions of GSK980TDi: automatic tool change and executing tool offset. Control logic of
automatic tool change is executed by PLC and tool offset is executed by NC.
