NS: Starting block no. of contour – beginning of contour section
Figures: Block number of the figure
Free closed contour: First contour element (not starting point)
Open contour: First contour element (not starting point)
NE: Contour end block no. – end of contour section
Figures, free closed contour: No input
Open contour: last contour element
Contour consists of one element:
No input: Machining in contour direction
NS = NE programmed: Machining against the contour
direction
H: Mill cutting direction
0: Up-cut
1: Climb
I: Max. approach
F: Approach feed for plunging (default: active feed rate)
E: Reduced feed for circular elements (default: active feed rate)
R: Apprch angle (default: 0)
R=0: Contour element is approached directly; infeed to starting
point above the milling plane, then vertical plunge
R > 0: Tool moves on approaching/departing arc that connects
tangentially to the contour element
R < 0 with inside corners: Tool moves on approaching/
departing arc that connects tangentially to the contour element
R < 0 with outside corners: Contour element is approached/
departed tangentially on a linear path
P: Milling depth (default: depth from the contour definition)
XS: Millg. top edge lateral surface (replaces the reference plane
from the contour definition)
ZS: Millg. top edge face (replaces the reference plane from the
contour definition)
RB: Return plane (default: back to start position)
Front or rear face: Return position in Z direction
Lateral surface: Return position in X direction (diameter)
D: Start elem.no.
The direction of contour definition for figures is counterclockwise.
The first contour element for figures:
Circular slot: The larger arc
Full circle: The upper semicircle
Rectangles, polygons and linear slots: The orientation angle
points to the first contour element.
V: End: elem.no.
A: (Mill=0/PredrillPos=1)
NF: Position mark – reference at which the cycle stores the hole
positions (range: 1 to 127)
