Chamfer
Single pos. A rectangular spigot is machined at the programmed position (X0, Y0, Z0).
Pos. pattern Several rectangular spigots are machined in a position pattern (e.g. full circle, pitch
circle, matrix, etc.).
The positions refer to the reference point:
X0 Position in X direction (single position only), abs. or inc.
Y0 Position in Y direction (single position only), abs. or inc.
Z0 Workpiece height (single position only), abs. or inc.
W Width of spigot after machining
L Length of spigot after machining
R Radius at edges of spigot (corner radius)
α 0 Angle of rotation
Z1 Depth of spigot (abs. or inc.) (not for chamfer)
DZ Max. depth infeed (Z direction) (not for chamfer)
FS Chamfer width (for chamfer only), inc.
ZFS Insertion depth tool tip (for chamfer only), abs. or inc.
UXY Finishing allowance in the plane in relation to length (L) and width (W) of the spigot;
Smaller spigot dimensions are obtained by calling the cycle again and programming
it with a lower finishing allowance.
(not for chamfer)
UZ Finishing allowance in depth (tool axis) (not for chamfer)
W1 Width of specified blank spigot (important for determining approach position)
L1 Length of specified blank spigot (important for determining approach position)
