SOLIDWORKS ‘Splines / Bcurves’ to WoodWOP contours.

If you have ever needed to create a smooth, ‘arbitrary’, curved contour in WoodWOP from a SOLIDWORKS model you have probably been a little disappointed with the results.  ‘It’s not smooth!’.

The primary reason is in how the spline is converted into the WoodWOP contour and not how it is machined.

Most conversion programs will convert points on the spline to accurate contour points but they connect the points with straight lines.  Only by reducing the distance between the points can the contour be improved.   ONGAA CAM takes the connecting line into account as well and if it is curved, it supplies WoodWOP with the information to define an ARC.  This arc simulates the actual spline much more closely.

Take for example a perfect circle and imagine selecting 8 points along the circle to ‘guesstimate’ the contour.  This is of course exaggerated but it illustrates the point.  Now use those … Read the rest

Benefits of ONGAA CAM over DXF-Style WoodWOP MPR creation.

We were recently asked to summarize the benefits of using ONGAA CAM over generating DXF layers to load machining into WoodWOP as MPR (MPRX).

To those using ONGAA CAM the benefits are clear:

  • No need to create drawings and layers.
  • No need to edit each process in WoodWOP to add the parameters that can’t be set in the ‘cryptic layer names’ – like tools changes
  • No need to learn a new interface – ONGAA CAM provides access to all WoodWOP parameters.
  • One click MPR load into WoodWOP – ‘visual verification’.
  • Complex contours including lines, arcs and splines simply by selection
  • Hole Wizard arrays and Linear Pattern arrays in one selection.

But the above lists does not fully capture all the benefits because as we all know ‘first time’ is not always right.  What happens if the model needs to be adjusted?   Lets say two features were moved by 2mm and … Read the rest

Under Development – PLY File Generation for WoodWOP

As with all thing,s a path is easy to follow when you can see it.  Toolpaths are no different.

The straight forward – follow these edges – toolpaths are a snap in current version of ONGAA CAM.  Click on a vertex, then an edge and another and so on.  The resulting toolpath is both simple and easy to visualize.

But what about surfaces? Those 3 dimensional curves than have no points or lines to click on.

Well, we are going something about those.  PLY file generation will allow you to select a surface and ONGAA CAM will map out a toolpath to machine the surface.  Files will be MPR compliant files able to be used both in ONGAA CAM as well as WoodWOP. With options like ‘Step Increment’, WoodWOP tool selection and path trace angle several ply files can be produced providing initial clearing, rough and finishing toolpaths.

Complex SOLIDWORKS Contours converted to WoodWOP

As many of you already know, just because you can draw it does not mean its easy to create a WoodWOP contour to match — well at least not by hand or using DXF…

With ONGAA CAM it is as easy as selecting edges and whatever machining parameters WoodWOP wants to know. (Direction of travel, tool number ,  Tool compensation etc.)

Take for example the outline of the state of Indiana.

In ONGAA CAM (SOLIDWORKS), simply select a staring point, the first edge and then select tangency. Then with a couple more edge selections to close the loop we are done with the now 51 edges including straight line, arcs and spline curves.

Now launch WoodWOP from within ONGAA CAM to see the result.

It really is that simple.

The contour delivered to WoodWOP is 831 lines and arcs that fall withing the 0.5 mm default approximation setting.

ONGAA CAM – Nesting

 

Auto-Nesting is a vital time-saver for any cabinet manufacturer.

 

 

 

 

 

 

ONGAA CAM now offers a basic auto nesting function that works directly from the assembly.

Options include:

  • auto rotate of part (here grain does not matter)
  • fill horizontally or fill vertically
  • align to grain (each part to the current sheet)
  • sorting options which may alter the part arrangements.
  • multi-sheet output

Here is the generated MPR, as seem in WoodWOP, generated directly from Solidworks.
Total time to generate a ‘re-sized’ 4 unit cabinet set… 45 seconds !

 

 

 

 

 

Contact us today to see how ONGAA CAM can increase your productivity (and possibly quality of life).  We will arrange an online demonstration your parts and assemblies so you know it will work for you.

ONGAA CAM – Extending the parametric model beyond WoodWOP

Before I can explain how ONGAA CAM extends parametric models,a definition of what that is is due. ‘Parametric’–with the use of parameters –is a way of defining something where parameters or variables are used to make something scale.

  • For example,a box,24″by 12″by 6″can be said to be half as wide as it is long and half as deep as it is wide,and the box is 24″long (LENGTH).

In this simple example,only one number need be provided and all other number can be derived.  With this model any sized box can be made and it will always retain the desired proportions. If only it were that simple …. Lets take that same example and add a little reality…make the box out of 1/2 ”plywood (this applies to all sizes).  The simple addition of a fixed width makes the dimension of the ‘components’of the box a little more complex to calculate,but still

ONGAA CAM – Real Parts – SOLIDWORKS to WoodWOP

may2012 113It is not often that a customer is so pleased with a product that they take extra time to say ‘thank you’.

In this case the thank you came as ‘The First Part’ the customer produced with ONGAA CAM.

The part was modeled in SOLIDWORKS 2011 and used ONGAA CAM V1.140 for the HOMAG series CNC machines.

 

 

 


 

Once processing was applied,ONGAA CAM produced the MPR file  (compatible with WoodWOP 5 and 6) used to NC Gen the final instructions.

The only issues we ran into was getting the part drawn accurately.  The beauty was as we corrected the drawing,all our processing moved with it.  ’No recalculations required!’.

This view of WoodWOP provides a glimpse into how it could have been created manually with each calculation done by hand. (and drawing changes need to be recalculated)

 


The part required machining on all 6 sides.  With the … Read the rest

ONGAA CAM – Meeting the challenges of Computer Aided Manufacturing

Automating manufacturing comes with a long list of questions.  The question that follows ‘Which CNC machine to buy?’is usually followed by ‘How do get from my drawing to the CNC making parts ?’.

Each CNC vendor has a basic solution for that.  Type in all the numbers by hand …. or at least try to type them in (correctly).

If the ‘program’will never change and will make several million units,then this simple process is cost effective enough.  But what about the smaller manufacturer?  2-10 Units a year (of that size and shape).  Manually typing in each number for every size is just not practical.

If you use a 3D modeling program like SOLIDWORKS then adjusting the size of a ‘Model’is relatively simple.  If there was only a way to attach the processing information to the Solidworks Model.  That way the processing stretches as my model does.  Even better …why not … Read the rest
