364 6 DIN Programming
6.20 Face Machining
Contour and figure milling cycle, face G793
G793 mills figures or (open or closed) "independent" contours on the
face. G793 is followed by:
The figure to be milled with:
Circle (G304), rectangle (G305) or polygon (G307)
Conclusion of milling contour (G80)
The independent contour with:
Starting point of milling contour (G100)
Milling contour (G101, G102, G103)
Conclusion of milling contour (G80)
Parameters
Z milling top edge
ZE milling floor
P maximum infeed (default: Total depth in one infeed)
U overlap factor: Machining of contour or pocket (default: 0)
U=0: Contour milling
U>0: Pocket milling—minimum overlap of milling paths =
U*milling diameter
R approaching radius: (Radius of approaching/departing arc)—
(default: 0)
R=0: Contour element is approached directly; feed 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 for inside corners: Tool moves on approaching/departing arc
that connects tangentially to the contour element.
R<0 for outside corners: Length of linear approaching/departing
element; contour element is approached/departed tangentially.
I oversize contour-parallel
K oversize Z (in infeed direction)
F feed rate for infeed (default: Active feed rate)
E reduced feed rate for circular elements (default: Active feed rate)
H cutting direction (default: 0): The cutting direction (see
graphic support window) can be changed with H and the direction
of tool rotation.
H=0: Up-cut milling
H=1: Climb milling
Example: G793
