Input:
–
If the contour is not yet described, specify the name of the starting label and press the following softkey. If the controu
is already described (name of starting label: name of end label), directly press the following softkey:
The control system automatically creates starting and end labels from the name entered and the program jumps to
the contour editor.
–
Use the following softkey to confirm your input and return to the screen form for this cycle:
Examples:
NPP=CONTOUR_1
NPP=START:END
MID (infeed depth)
The MID parameter is used to define the maximum possible infeed depth for the roughing process.
The cycle automatically calculates the current infeed depth used for roughing.
With contours containing relief cut elements, the roughing process is divided by the cycle into individual roughing sections.
The cycle calculates a new current infeed depth for each roughing section. This infeed depth is always between the
programmed infeed depth and the half of its value. The number of required roughing steps is determined on the basis of the
total depth of a roughing section and of the programmed maximum infeed depth to which the total depth to be machined is
distributed equally. This provides optimum cutting conditions. For roughing this contour, the machining steps shown in the
illustration result.

;The rough turning contour is the com-
plete program CONTOUR_1.
;The rough turning contour is defined as
a section in the calling program, which
starts from the block containing label
START to the block containing label END.
