4 Workflow from the preliminary setting to exporting data Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 10 Operations flow from left to right. Step 1 Step 9 Step 1 Preliminary setting In this preliminary step, you will save the data of the parts used in this guide and customize the default settings for DWX-50. Step 2 Creating a new project file In Step 2, you will create a new project file and select the project type and the milling machine specified in Step 1. Step 3 Importing the stock data In Step 3, you will import the stock data, which was saved in Step 1. When using Zirconia, you need to scale the size of the object. Step 4 Importing the image of parts In Step 4, you will load the object image by selecting the teeth type and the STL file. Step 5 Defining the orientation of the part In Step 5, you will define the correct orientation of the object so that the object should face upward. Step 6 Identifying the preparation line In Step 6, you will define the preparation line. Step 7 Attaching support pins In Step 7, you will attach support pins to the part. Support pins are created automatically or manually. Here, we will attach one manually for practice. Step 8 Layout In Step 8, you will move and rotate the object on the X-Y plane for practice, which is useful when you wish to change the position of the part. Step 9 Saving the project file In Step 9, you will save the project file (*.dmproj). Make sure to save the file before generating the toolpath. Step 10 Exporting the milling data In Step 10, you will export the milling data. 3

Step 1 Preparation Basic operation procedures In this preliminary step, you will save the data of the parts used in this guide.

Step 3 Importing the stock data In Step 3, you will import the stock data, which was saved in Step 1. When using Zirconia, you need to scale the size of the object.

Note that you should decide which material you use at this point; if you change the material later such as from Zirconia to WAX or from WAX to Zirconia, you have to come back to Step 3 to repeat the

10 Step 3 Importing the stock data In Step 3, you will import the stock data, which was saved in Step 1. When using Zirconia, you need to scale the size of the object. Look at the side of the disk to find the scale. Note that you should decide which material you use at this point; if you change the material later such as from Zirconia to WAX or from WAX to Zirconia, you have to come back to Step 3 to repeat the same operation again from setting the scale. When you use a new stock, select the file from the New Stock folder. When you use a used one, select the file from the Part Used Stock folder. Here, we will use a new stock as an example Import stock 1 From the Toolbox, click the [Project Setup] tab >> (Setup stock for machining) icon.
