control
[Control details]
The linear interpolation to other linear axis is executed performing circular interpolation
from current stop position (start point) to specified circular relative end address (X
1, Y1)
or linear axis end point relative address (Z
1), and the incremental helical interpolation
control is executed so that it may become a spiral course.
It goes around on the specified circle for the specified number of pitches, the circular
interpolation which had remainder specified is executed, and positioning to end
address is executed. The radius-specified circle specifies circular interpolation method
connected start point and end point at the seeing on the plane for which performs
circular interpolation.
Operation details for incremental radius-specified helical interpolation are shown below.
