@711 <Var 1> <Var 2> <Var 3>
This command is required as intersection calculation in turning cycle L95 "Stock removal".
With @ 711, the intersection of a search path with a contour element is determined.
The intersection calculation requires a total of 8 parameters as input data for the first contour
element. The first R parameter number is defined by <Var 2> (Rn). The second contour from
< Var 3> (Rr) onwards is not presently implemented, but one R parameter or another must
be specified when programming. The output data of the intersection calculation is stored in a
total of 3 R parameters starting at R parameter <Var 1> (Rm). The direction of search is pro-
grammed after the command as normal traversing movement. Both axis values are required in
order to determine the intersection. The output data of reference preparation are used here as
input data for the intersection calculation.
