By using the Workflow Wizard in SUM3D, you can process a milling run quickly and effectively. This walkthrough is for users in the High or Maximum level interface. For the Medium level interface or lower, the software will automatically guide you through the process after step 1. 


1. Open up SUM3D and click on the New Job button: 

You will be presented with the following window asking for some basic information about your new milling job to get started:


Select the material that you plan on milling & the machine that you plan on milling with. After you have made your selections, double check that the File Name is sufficient and click “Save” to continue.


NOTE: By default, the time and date of the new job creation will populate under the File Name. If you want, you can replace this with your own custom name by deleting the text and typing over it. There is an option in the default settings area of the software that allows you to select whether you want your job names to auto-generate with the date and time or to simply be blank by default. If your machine is properly configured, you will see a virtual representation of your fixture appear on the screen.


2. Click on Import STL files:


You will be presented with the following window that is asking for the .STL Files to be milled as well as

the Type of restoration that you are selecting in this window.



Select your .STL File to be milled and click on the type of restoration that you’ve highlighted. At this

point, you can also select more than one restoration by using the following combination with your

keyboard and mouse: Control + Left Click for individual item selection or Shift + Left Click for multiple

item selection. When you’ve selected the item to be milled and the Object Type, click “Open” to import the .STL File/s.

NOTE: You can only select and import one object type at a time. So if you had a mixed job of Crowns, Copings and Bridges: You would import all of your Crowns at the same time, then re-open the Import STL Files window and import all of your Copings at the same time, repeating the process for your Bridges. If needed, you can navigate to a different directory to find your files. It is recommended to store all of your .STL Files in a directory that can be easily access by the SUM3D Software. The Default Directory that SUM3D will look in for importing STL Files can be changed in the Default Settings.


You will notice that the crown has been imported into the puck and that the maximum thickness will

be displayed. If you’re importing multiple items, this window will display the maximum height taken up by the items imported.



3. Click on Select Machining Strategy to import the Cutting Strategy to be used for milling:



If the strategy is properly configured, a window will pop up asking for you to choose Milling Options for the Job. Choose your options for this milling run and click on “Ok” to continue. Based on your

individual strategy, you choices may vary from the following image:



4. Click on Select / Create Stock

You will see the following window: Choose a Part Used stock that’s been milled out of previously or

click on “Create” to generate a new Stock / Blank for milling.



Choose your Shape of Stock / Blank from the “Shapes” drop-down and choose a thickness. If there is an appropriate Shrinkage Factor, (for Zirconia) enter the numerical value here. The Stock Name and Lot Code values are optional but will show up in the Stock List for used stock and on the Report that can be generated after calculation.


NOTE: The minimum blank thickness required will display the minimum thickness that you will have to create in order to accommodate the items that you have imported in this job. Also, if you are working with a percentage based value for shrinkage, this can be changed in the Default Settings.


After you’ve created the Stock, the system will prompt you with the following two windows:




NOTE: These steps are optional and will automatically execute if you are on a Medium Level of

interface or lower. If you choose to say “No” to the Automatic Nesting, you may have to manually place these items within the stock for milling.

(See walkthrough for performing optional steps within SUM3D)



5. Click on the Start Calculation for Machining Button:


You will be prompted by the following window:


This is the post-processed filename that will be created after the calculation completes. After the file is created, it will be opened with Notepad to show that the calculation is complete.


For the Roland DWX-50, you will see the following window:


If you select Yes, the file will be streamed to the VPanel Program and queue up each operation one after another – much like a print job on a printer.

If you select No, the calculation will execute and the file will be output to the following default location:

C:\sum\cnc

or

C:\RolandDG\cnc

You will be presented with a window that will show the corresponding locations for each tool position within the machine.


Your calculation will execute following the option that you selected from above.



You have now completed the processing of your Milling Job. If you want to perform additional steps such as adding / removing Support Pins, Re-positioning & Rotating items within the disc, please see the walk-through for performing optional steps within SUM3D.
