Using Configurations with nesting

Parts may require an alternate configuration to be created that reflects the part as it will ‘be machined’ rather that ‘as presented’.  One common situation for this is when parts are created either as multibody or with extra extrudes.  The extra body or extrude may be edge-banding for example which will be added post machining.  The ‘as machined’ configuration would simply suppress the feature (extra body, extrude etc) to reflect a part in its true geometry.

When parts require this additional (SolidWorks) configuration and these parts will be nested it is important that the master assembly also gets an extra configuration.  This is because the it is the assembly which drives which configuration will be set to active during the nesting process.

Nesting – Automatic separation of parts based on thickness and material

The earlier version of the nesting functions of ONGAA CAM assumed each nesting run would be for one thickness of material and it was up to the programmer to ensure parts were grouped by material and thickness.

Based on valuable customer feedback we have changed this.

As of version 1.3.26.0, ONGAA CAM can now determine if a part belongs to a nesting group based on work piece definition parameter ‘Thickness’ and on a new parameter called (Material).  Each Nested MPR created will also have a comment added which will indicate the material and the thickness used for nesting.  As before, each ‘Nested MPR’ is still a 100% compliant MPR meaning that individual processes can still be adjusted at the console.

Since material is often defines as a Custom Property within SOLIDWORKS, we have added the ability to reference the custom property name in the work piece definition.

This feature makes … Read the rest

Interference Nesting with ONGAA CAM

Automatic Nesting

Several automatic nesting strategies are available in ONGAA CAM which provide a quick and easy way to nest rectangular parts across many sheets of material (directly from SOLIDWORKS).   ONGAA CAM optimizes the nest to both maximize material usage as well as minimize tool changes.

But not all part are created equally.  Automated nesting assumes the required material is as defined in the work piece definition of WoodWOP.   Odd shapes would waste both material and time.

 

Manual Nesting – ‘Nudging’

With the latest version on ONGAA CAM, manual nesting or ‘Nudging’ is now available.

Parts can now be selected, moved between sheets, moved on a sheet as well as rotated using intuitive button controls or keystrokes.

SOLIDWORKS-WoodWOP Nesting optimization with ONGAA CAM

Optimizing Processes and Optimizing MPRs

Nesting – or combining multiple parts onto one sheet is a vital function for ‘Flat Table’ operators.

Until now, ONGAA CAM‘s ability to nest ‘complete assemblies’ has been received with both enthusiasm and a little reservation.

Users have ‘enthusiastically’ created all kinds of assemblies in SOLIDWORKS, combining nested assemblies, parts with multiple configurations and ONGAA CAM has created multiple sheet MPRs without a hitch.

Then came the next requests for improvements …

  • How do I optimize the the processes? — the generated nested MPR made one part at a time — I want the number of tool changes to be reduced.
  • I have a big assembly, how do I do more than 4 sheets.
  • How do I tell ‘what part is what’ when looking at the nesting preview.
  • How do I print the nest layout (with parts listed) so the ‘guys on the floor’

Nesting – Improvement and Optimizations

Since nesting is all about ‘optimizing’, we took another look at optimizing the nesting process to see where we could improve upon what we had.

Step 1, has not changed.  From an assembly click ‘Gen, Nested MPR’Start_nest

With a single click, all ‘unsuppressed’ parts of the assembly will be listed, sized and initially laid out on as many sheets as it takes and that layout displayed.

The nesting process will take a ‘configured’ sheet size – width, length and thickness as well as a perimeter scrap dimension ans apply these while arranging the parts.

Grain orientation of part and board was available in the previous release as were the numerous layout options and these remain the same.

 

Step 2, Adjusting the layout options has new features added to help the process.Main_nest_panel

The first is a quick reset of the sheet thickness based on the thickness of the parts.  If … Read the rest
