1.3.4 Interpolation function
Interpolation is defined as a planar or three dimensional contour formed by path of 2 or multiple
axes moving at the same time, also called Contour control . The controlled moving axis is called link
axis when the interpolation is executed. The moving distance, direction and speed of it are controlled
synchronously in the course of running to form the required Composite motion path. Positioning
control is defined that motion end point of one axis or multiple axes instead of the motion path in the
course of running is controlled.
GSK980TDc X and Z axis are link axes and 2 axes link CNC system. The system possesses
linear, circular and thread interpolation function.
Linear interpolation: Composite motion path of X, Z axis is a straight line from starting point to
end point.
Circular interpolation: Composite motion path of X, Z axis is arc radius defined by R or the circle
center (I, K) from starting point to end point.
Thread interpolation: Moving distance of X or Z axis or X and Z axis is defined by rotation angle
of spindle to form spiral cutting path on the workpiece surface to realize the
thread cutting. For thread interpolation, the feed axis rotates along with the
spindle, the long axis moves one pitch when the spindle rotates one rev,
and the short axis and the long axis directly interpolate.
