OneCNC Hybrid modeling provides a
powerful, fully functional CAD system with a
large number of dedicated tools for
constructing surfaces solids and geometry.
Solids can be created by adding or
subtracting simple solid shapes or by far
more advanced techniques such as, sweeping,
extruding and surfacing. Surfaces and solids
can also be constructed from 2D drafting or
3D wire frame geometry. OneCNC has an
extensive number of geometry surface and
solids modification tools that can be
applied to either existing geometry or
imported models. Because OneCNC is one
cohesive integrated system the CAM is
inherently just part of the system. Right
down to the job sheets is all part of the one database and
therefore accurately produced. Details can include who
designed the part, who machined it and on which
machine including the tools used. Cycle times are
created and are especially handy for estimating and quoting purposes
calculating each function time separately. This enables the
user to design and program the part to get the optimum times
Extensive range of CAD interfaces OneCNC can work directly with Parasolid, IGES,
STEP, Solid Works, VDA, Rhino, STEP, SAT, native Autodesk DWG and DXF files. This
extensive range of translators ensures that users can work
with data from almost any source. The ability of working with
complex designs are a must in this industry and using OneCNC
the benefits are easily seen from the simplicity with which
it can handle customer's CAD data files. OneCNC can
work directly with wire frame, solid, surface and STL mesh
data or a combination of all four. OneCNC also provides the
user with tools to work with any CAD model or to quickly
repair modify or edit the models provided. This is often
necessary to make the part suitable for machining.
Intuitive interface Full Windows graphical interface provides a
familiar and user friendly means of creating the CAD. A
unique effective NC manager tree structure makes it easy to
navigate around the machining operations. Machining
parameters for depth of cut, step over, ramp angle etc. are
input using a highly graphical Wizard driven interface for
all the machining functions. This feature is to guide the user to each
setting as required. Most commonly used variables and
values can easily be edited from the manager without
having to edit the wizard dialogs again. Initial selection
of the tool path is simplified through the interactive method
of showing the type of tool path the user is selecting. If
the user wants the change the particular strategy is is
often a simple process of selecting an alternative from the
tool path selection dialog without having to start over.
Template machining. To speed up the programming, templates containing
tooling, operations, feeds, speeds, depth of cut etc. can
all be stored for reuse on similar or families of parts.
Once used they become a real time saver. When saved as
favourites they are available for
later use in any part for the same purpose.
This is a highly intelligent system that saves each tool
separately for each function and automatically provides the
favourite history when the function is opened and the tool
selected. Applying the template to a new part will
automatically create a new set of tool paths using the same
settings, greatly reducing programming time. This provides the ability
to use feeds and speeds that have been optimised from
previous use. This provides significant savings in programming and
machining time. Favourite settings are not left to your memory
anymore and also provides the ability to have other
programmers using the knowledge and resources of the proven
OneCNC has a unique tool changer where a user can keep the same tools in the changer as he has in the machine carousel. This provides the ability to see the current tools used and the current tools available for the programming of the parts.
Open and closed pocket
OneCNC provides high speed and traditional multiple island pocketing
with the ability to define draft angles for
the pocket and island walls. Open sided
pockets allow the user to identify the open
boundary allowing the cutter to
automatically remove the boundary material.
Users are able to select from the
traditional style closed tool path or the
new HS highly efficient maximum tool
engagement type tool paths. HS style tool
paths ensure that there are never any full
width cuts to guarantee constant climb
cutting tool loads. Tool wear is spread more
evenly along the cutting edge moving the
force further up the tool reducing
deflection and minimizing load.
This improves cutting conditions allowing
higher machining speeds to be maintained.
User settings include high feed for all
directional movements to improve non cutting
movement speed. The overall result is
savings of up to 40% in actual cutting time.
High speed 3D rough machining
OneCNC HS Z level roughing is roughing technology at its
best. This highly efficient method of metal removal has
users talking about the efficiency right around the globe. The tool paths using
the HS settings allow the tool to rough the part at a maximum
tool cut depth roughing from the top down.
step reduction technology the large step roughing levels are reduced
by machining using the same tool from the bottom to the
top of the cut level. The principle of this highly efficient method is
to allow large efficient roughing depths utilizing as much of
the flute length of the tool as possible then using the step reduction
technology machining ability to reduce these steps back to the top
leaving minimal material for finishing. This tool path ensures that there are
no full engagement cuts therefore guaranteeing a constant
tool load. This helps to reduce
deflection and vibration potential of the machining. HS rough
provides very efficient machining allowing higher machining speeds
resulting in savings of up to 40% machining time.
Rest machining One of the most efficient methods of removing metal
is to use the largest tool possible. This also means that often
smaller features on a model will then usually require rest
machining with a smaller tool to completely finish the
removal process. To allow this OneCNC provides rest
machining functions that detect where material is left so
that a smaller tool can be used to finish the part. The rest
reliably detects areas left by the previous tool and creates
a machining program to only remove the remaining material
with the smaller tool. This process can be
repeated with smaller tools as required to completely finish
the machining process. The tool path will automatically detect
the material left from the previous tools and by a very
efficient manner remove all the material left that can be
handled with each selected tool.
Flat surface machining For areas of the part which are flat this function will
automatically detect flat areas and machine them using a
flat bottomed tool. The machining time for these areas will
be significantly reduced and the surface finish will be
greatly improved by using a flat tool in a very efficient
manner rather than a ball mill that does not have flat area
contact. This is an excellent
machining function and when used in conjunction with ball end mill
for machining of 3D
models shapes. This function allows for very efficient machining of the
flat areas. The function uses the HS spiral approach
for efficient time saving of those areas.
Finish machining Planar unidirectional and zigzag tool paths can be set at
any angle. Boundaries can be set for control of finish area
machining and automatic gouge checking is used to protect
adjoining surfaces when machining these areas. Optimised cross-angle-machining can be applied to
create additional tool paths at 90 degrees to the original
tool paths to create a fine finish. Planar Roughing is also
a function in OneCNC and can be used to rough and finish the
part in one method of operation. Planar finishing is
recommended on all shallow angled areas to provide smooth
step over type machining for these areas. Z level machining
is the prime function in OneCNC for steep walled finish
machining which is included to make a powerful combination
for finish machining of your parts.
Profile and face machining OneCNC profiling operations give a choice of
machining direction, circular or direct angular approach,
and the ability to cut down to a depth with multiple depths
of cut. Multiple passes are possible and are easily set
combined with a finish pass of the selected format of custom
levels or full depth in one pass. Cutter radius compensation
capability either automatic or machine control provides
practical CNC code for use on the shop floor. When the
cutter cannot machine tight internal parts it will
automatically gouge check for these areas allowing them to
be machined with a smaller tool. OneCNC has HS Spiral or
zigzag or single direction face milling operations of flat
areas. These features combined with chain milling and clean
circle milling combine to make a comprehensive set of tools
for 2 1/2D machining.
What OneCNC has is much better than just associated
machining because it allows complete user control. OneCNC has two types of functionality for this.
The first being for geometry. The second type being models
and surfaces. For the geometry OneCNC provides the ability to use geometry on
the fly which can be active model geometry and if you change
it you have the choice of using it singularly or now
grouping it by re-picking into multiple setups for
processing. This is one of the
most talked about additions in the industry and is a quite unique
ability. For solid models and surface models in OneCNC if
you change the model the tool paths can easily and quickly
updated just by clicking to reprocess the tool path.
For those that like to make the best parts with the least
effort in finishing and polishing OneCNC has the pencil
trace that automatically fits the bill. This function is a
time saver for machining narrow grooves and fillets that are
not completely cut during the finishing functions. Pencil machining scans the model to find areas where the tool
will fit to perform a finishing pass to accurately finish
these filleted areas. This feature added to the steep and
shallow wall machining add to simplifying the finishing of
Multiple Part Processing
Multiple parts using sub-routines or sub programs have been automated for 2D or 3D parts
. This is automated for ISO Fanuc Haas and Heidenhain controls.
If you are into 4 axis Wrap machining this is the function
that will save you an enormous amount of time. The amount of time saved with this functionality is
just unbelievable. OneCNC unwraps and fully lays out the model surface
as a 2D layout. This layout can then be used for
machining and or engraving in 2D machining functions then
automatically wrapped using the 4 axis wrap function. This
provides a very efficient programming method for 4 axis
components. Just imagine how long it would take to manually
create the un-rapped geometry form this model we show here.
The function handles each component in the wrap including
all the island holes and shapes within the model or surface.
Model geometry and sectioning
Users experienced in CAD-CAM know just how important it is
to have good geometry to work with. With 3D models it is
essentially important and OneCNC provides the perfect tools
for this purpose. OneCNC has a model extraction tool that
can be used on a valid model to create a wire frame outline
of all edges and seams in single line geometry of
the model. This ensures that machining can be performed
easily on parts of models using this extracted information
with the knowledge that it is accurate and useable. The extracted
geometry is a real time saver when used in conjunction with
the various machining strategies as boundary control of tool
paths. Single surface extraction creates a valid geometry
boundary of the surface while it is still part of the model.
Sectioning provides the perfect tool for seeing the section
of your model real-time. Apply the plane to any angle and a
slider bar permits sectioning to expose all the inner shapes
Thread milling has been really simplified with the functionality provided by OneCNC.
Helical arc programming is automated from library thread selection even for tapered pipe threads complete with cutter compensation. This functionality is also included in the automated multiple parts providing great optimisation of production.
Hole feature recognition CNC machining often contains many combined holes
rather than just plain drilled holes.
OneCNC has the answer for this with hole feature
recognition functionality. This function automatically finds all the holes
on the part by way of hole feature recognition of the model.
recognizes holes in surfaces, circles or points of the model. These are all
automatically listed and can be individually or collectively selected to have an existing
pattern of holes applied or can be easily added through a
wizard system to perform the singular or multiple tasks as
required. Complete manufacturing can be
completed using feature recognition and previously saved
patterns with very few settings or clicks required. This functionality
combined with a complete range of drilling cycles makes it
simple even for the most complex components.
Tool path Verification and
Simulation.> Once programmed, the job can be simulated in realistic
rendered solids. OneCNC Milling automatically checks the
tool for collision with the model and or clamps and provides
a warning when there is going to be a collision, both
graphically and via on-screen warning messages. Graphical
verification of the completed tool paths can be back-plot for
complete measurement and visual prove-out. The cut part can be compared with Rest
Robot function to ensure that the part has been completely
machined. This helps to make sure the job is made right
first time before taking it to machining.
Corner rounding is a 2D automated process of applying a corner round to you finished parts.
This is similar to applying a chamfer to the part and uses a corner rounding tool that provides the radius cutting. Cutter compensation is also provided to assist in setting these tool paths to the exact position for quality finishing.
One of the difficult problems often encountered in machining is machining undercuts especially in porting type parts. OneCNC has the ability to use lollypop type tools to machine these type of parts.
OneCNC has the tools to quickly and accurately convert
photos, scans, or other suitable bitmap images to editable
and scalable geometry paths using its built in tracing
functionality. This allows the user to take an imported
image of customers logo and automatically trace it into
geometry suitable for creating machine ready 2D machine code
or project the image onto a model and create 3D machine
ready engraving code. Obviously the better image contrast
provides the best tracing however they can be easily edited
using the geometry tools over the top of the image.
Engraving 2D and 3D OneCNC has tools for engraving and provides the
functionality required to create tool paths for engraving
from Windows true type fonts or AutoCAD SHX type fonts. Any
Windows font from your directory can
be used for the tool path creation. All the required
engraving can be easily selected as one for automatic
engraving eliminating the necessity to select individual
text. This function as an automatic feature also handled
engraving projected onto models and surfaces from 2D images.
5 Axis simultaneous machining OneCNC has superb 5 axis simultaneous functionality available as an added module for the mill expert version. The 5 axis simultaneous has the ability to provide collision avoidance for the tool the tool holder the machine spindle and the machine head. Much of this has been automated including the ability to create the holders on the fly during the part programming.
Machine simulation. Tool path verification and preview can be applied
using the real machine dimensions and limits with the actual
machine movements to provide simulation. Cutting tool,
holders, jigs and fixtures can all be visually checked when
running the the interactive dynamic viewing display. Any
gouges on the tool path against the part will be easily
graphically seen and indicated. A library of actual 3, 4 and
5 axis machine indexers and multiple axis trunion are
available. OneCNC provides the user the required tools to
enable users to easily create the machines and or indexers
or a type not currently available.
An extensive library of advanced postprocessor's is included
or available to suit most machine tools and all
postprocessor's are fully configurable to suit individual
requirements. These are not just limited to the use of
generic G and M codes but include the addition of many
variables. Canned cycles for drilling to reduce program
length, circular interpolation, cutter radius and tool
length compensation all combine to produce reliable NC code
which is what you need on the shop floor. Posts are also
available for Heidenhain conversational type machine code.
