TE7: Continue machining - retrace support
15.2 Functional description
Contour ranges which are not logged are bridged by straight lines between the starting and
end points during reverse/forward travel.

Definition of terms
Interruption point
The interruption point is the point of the contour at which the traversing movement comes to a
standstill following an NC stop and reverse travel is activated.
Program continuation point
The program continuation point is the point of the contour at which reverse travel terminates
and program continuation is activated.
Retraceable contour area
Retraceable contour ranges consist of traversing blocks in the configured RESU working
plane (e.g. 1st and 2nd geometry axis of the channel), that are programmed in the part
program between the RESU start command CC_PREPRE(1) and the RESU stop command
CC_PREPRE(0) (refer to the "Retraceable contour ranges" screen).

Functional sequence (principle)
The principle sequence of the RESU function between the interruption point, program
continuation point and continuation of part program processing is described below.
