6.14 Interactive Working Plan Generation (IWG)
Deburring (G840)
The IWG generates the cycle G840, including the following
parameters, for the selected open or closed contour.
Parameters
K Retraction plane (default: back to starting position)
 Front/read face: Position in Z direction
 Lateral surface: Position in X direction (diameter)
Q Cutter position
 Q=0: Center of milling cutter on the contour
 For closed contours:
 Q=1: Inside milling
 Q=2: Outside milling
 For open contours:
 Q=1: Left of the contour (reference: machining direction)
 Q=2: Right of the contour (reference: machining direction)
H Mill cutting direction
 H=0: Up-cut milling
 H=1: Climb milling
R Approach radius
 R=0: Approach contour element directly
 R>0: Approaching/departing radius that connects
tangentially to the contour element
 R<0 for inside corners: Approaching/departing radius that
connects tangentially to the contour element
 R<0 for outside corners: Contour element is approached/
departed tangentially on a line
P Milling depth – plunging depth of the tool (default: Chamfer
width (from “Machining attribute – deburring”) + 1 mm)
L Oversize
The oversize “shifts” the contour depending on the cutter
position Q (generates “Oversize G58” before the milling cycle):
 Q=0: Oversize will be ignored
 For closed contours:
 Q=1: Reduces the contour
 Q=2: Enlarges the contour
 For open contours:
 Q=1: Shift to the left
 Q=2: Shift to the right
Deburring: The chamfer width is defined as machining
attribute.
