Placing an Object (Crown) on a Pin/Block

This section introduces the appropriate workflow for using the proper clamp or adapter to place an object (crown) on a pin-type CAD/CAM block.

Importing an Object

Procedure
  1. Select one .STL file to import.
  2. Select the dental prosthesis type for classification.
  3. Click the check mark button to proceed to the next step.
    ImportObject2
    MEMO

    A preview of the selected .STL file is displayed at the bottom of the window. Click the image to display a separate pop-up window in which you can rotate and zoom in on the preview.

    When the dental prosthesis is imported, a message prompting you to perform the next operation is automatically displayed in CAM.

Selecting the Material

Procedure
  1. Check whether the dental prosthesis fits in the material.
    If the material is smaller than the dental prosthesis, the parts that project outside the material are displayed in red. This is useful in judging in which block the dental prosthesis fits.
  2. Select the green + (plus) mark next to the new blank to use.
  3. Select the check mark to continue.

Placing the Dental Prosthesis

After selecting the stock, perform final adjustments as necessary during the dental prosthesis placement step.

If there are no changes to items such as the orientation of the dental prosthesis and the placement of the support pin, use Save Toolpath to start the calculation process.

Starting Cutting

Options for starting calculation (starting cutting) are available in this step. If a milling machine is connected, the CNC file is output to the milling machine and cutting starts immediately after the first rough milling toolpath calculation finishes in DGSHAPE CAM. You can also click another option (toolpath) to save the CNC milling file.
StartMilling_Toolpath
Depending on the cutting strategy set for the material, milling options that match the material may be displayed.
MIllingOption
You can select the milling option from the above list (the options may vary depending on the cutting strategy). This allows you to customize the characteristics of cutting while it is in progress.
When you select a strategy option, the following tool table opens.
SelectMillingBar
MEMO

This tool table is displayed to call your attention to the cutting bur used in this job. A different material may require a specific cutting bur for the optimal cutting conditions, and this information may change from one material to the next.

The first column of this tool table shows the cutting bur slot number, size of each cutting bur, and product name of the recommended cutting bur. Some milling machines can directly track the cutting bur service life from the controller. If you are using one of these machines, you can disable the cutting bur service life tracking function.

Cutting Bur Service Life Tracking by DGSHAPE CAM

When cutting bur service life tracking is enabled on the milling machine, the following pop-up window will appear.
PinBlock10

This window asks if you want to apply the cutting bur service life to the in-use cutting bur being tracked by DGSHAPE CAM. You can use this selection to exclude the current calculation from the cutting bur service life tracking. For example, this is useful when you want to perform the calculation but you do not want to execute an actual job on the milling machine.

Simulating Remaining Cutting

Depending on the DGSHAPE CAM settings, the following pop-up window may appear during calculation.
PinBlock11

Select Yes to display a color map that indicates the cutting that may remain due to the limits of the cutting bur at the end of the calculation process. (As an example, if the cavity is designed to be narrower than the radius of the cutting bur, this material will remain without being milled by the milling machine.)

When you select the simulation of the remaining cutting, the following image is displayed after the calculation.

Completing the Toolpath

When the calculation finishes, the following pop-up window that shows the output location of the CNC file appears.

You can manually move to this directory or use the Tools - CNC Output Files button to move to it.
