tion (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.
