HELICAL INTERPOLATION REVIEW
Three pieces of information are required in a helical block: the definitions of the center
of the arc, the lead, and the end point of the arc. Two of the addresses I, J or K are used
to define X, Y or Z dimensions of the center of the arc. The third I, J or K address is
the lead along the cylinder axis in inches per radian (2 radians = 360°). The end point
of the arc is defined by X, Y, Z. If X, Y, Z, I, J or K value does not change from the
previous block it need not be programmed. |
