Different type of cut pattern for tool in face milling operation in Nx Siemens
manufacturing
Cut Pattern enables you to define the shape of the tool path.
Some patterns cut the entire region while others cut just around the perimeter
of the region. Some patterns follow the shape of the cut region, while others
are independent of it.
The following cut patterns are available for the Boundary drive method and for
the Area Milling drive method with non-steep cutting.
Parallel patterns Zig-Zag , Zig , Zig With Contour , and Zig with Stepover
create cut patterns defined by a series of parallel passes.
Zig-Zag, Zig, and Zig With Contour work in the same way as their
counterparts in Planar and Cavity Mill.
Zig-Zag Zig-Zag patterns create passes that cut in opposite directions while
stepping over in one direction. NX generates a Zig pass in one direction,
steps over to the next pass while continuing to cut, and creates a Zag pass
in the opposite direction. This cut type maximizes cutting moves by allowing
the tool to remain continually engaged during stepovers. The result of
cutting in opposite directions is a series of alternate Climb and
Conventional cuts
Zig-Zag For additional details, refer to the discussion of Zig-Zag in Planar
and Cavity Milling.
Zig–Zag with Lifts
Creates passes that cut in opposite directions. Stepovers are non-cutting
moves. At the end of each pass the cutter retracts, traverses, and cuts in
the opposite direction.
Zig-Zag with Lifts pattern Zig patterns cut in one direction, then move from
one cutting pass to the next by retracting, traversing to the start of the
next pass, and cutting again in the same direction. Step overs are
non-cutting moves. Creates cuts in one direction. Step overs are non-cutting
moves. At the end of each pass the cutter retracts, traverses to the start
of the next pass, and cuts again in the same direction For additional
details, refer to the discussion of Zig in Planar and Cavity Milling.
Zig with Contour
Zig with Contour patterns are similar to Zig patterns, and also follow the
boundary contour along the stepovers
Zig with Contour For additional details, refer to the discussion of Zig With
Contour in Planar and Cavity Milling.
Zig with Stepover Zig with Stepover patterns create a Zig pattern with a
cutting Stepover. The following figure illustrates the sequence of cutting
and Non-Cutting moves for Zig with Stepover.
Pass 1 is a cutting move.
Passes 2, 3, and 4 are Non-Cutting moves.
Pass 5 is a Stepover and a cutting move.
Pass 6 repeats the sequence.
Zig with Stepover Radial patterns
Radial Zig-Zag , Radial Zig , Radial Zig With Contour , and Radial Zig with
Stepover create linear cut patterns extending from a user-specified or
system calculated optimum center point. This Cut Pattern allows you to
specify a Pattern Center, and pocketing method as Inward or Outward. It also
enables you to specify an angular stepover, which is unique to this cut
pattern. The Stepover distance for this cut pattern is measured along the
arc length at the boundary point farthest away from the center.
Radial Zig with Inward Pocketing Concentric patterns Concentric Zig-Zag ,
Concentric Zig , Concentric Zig With Contour , and Concentric Zig with
Stepover create progressively larger or progressively smaller circular cut
patterns from a user-specified or system-calculated optimum center point. In
areas, such as corners, that the full circular pattern cannot extend into,
concentric arcs are created and connected before the cutter moves to the next
corner to continue cutting.
Concentric Zig-Zag with Inward Pocketing Profile Profile creates a cut
pattern that follows the perimeter of the cut region. Unlike Follow
Periphery which is designed to hollow out the entire region, this option is
intended to cut just along the boundary. Profile activates the Additional
Passes option which may be used to remove material in a specified number of
successive stepovers.
Profile - Climb You may create additional passes that allow the tool to step
toward the boundary to remove material along the wall in successive
concentric cuts by specifying a value in the Additional Passes field.
Profile modifies the tool path so that it does not cross over itself, and so
that it does not gouge the part in areas where the cutter is too large as
illustrated below. Profile Follow Periphery Cuts along offsets from the
outermost edge that is defined by part or blank geometry. Internal islands
and cavities require island cleanup or a cleanup profile pass. Climb or
Conventional cutting is maintained.
Standard Drive Not available for Area Milling . Standard Drive creates a cut
pattern similar to Profile that follows the perimeter of the cut region.
Unlike Profile, Standard Drive does not modify the tool path to prevent
crossing over itself or to prevent gouging the part. Standard Drive causes the
cutter to follow the boundary exactly as it was specified.
