WARNING : To execute an exit in direction Z+, it is necessary to program a NU value different from zero. In these
cases it is possible to program a very small angle, as in the preceding example.
Through the NU parameter it is possible to skip the final profile contouring, normally executed.
y p ogramming a non zero value in the NU parameter, at the end of the last roughing pass,
uring, a rapid movement is executed with the direction given by the NU va
U parameter defines the exit angle of the last
the machining executed. The exit is executed until the raw dimension is encountered.
To understand the meaning of the NU parameter, it is possible to refer to the two following examples:
