Manufacturing settings for material groups

The manufacturing settings for material groups apply to all subordinate single materials. In particular, the configuration of optional tools has a significant impact on manufacturing quality.

Optional tools

In this area, you can activate or deactivate tools for optional manufacturing steps during finishing. These can significantly improve manufacturing quality, but they also increase manufacturing time.

For certain geometries, the use of optional tools is necessary to ensure sufficiently precise manufacturing. These include, among others:

  • Right-angled inner edges of screw-access channels

  • Connection geometries for two-piece abutments

  • Tight cavities in anterior crowns

When it comes to purely aesthetic improvements, the use of optional tools is typically a cost-effective decision.

You can activate optional tools using the toggle switches and icons:

  • Use the toggle switches below the Optional tools label to activate the general use of the respective tool.

  • Use the icons below the Area of application label to select where dentalcam applies the tool. A blue border indicates that an optional tool has been activated for the respective application area.

General parameters

x250-Fx-xx

Use single tooth cutter

(xxxx-x1-xx)

Reduces the manufacturing time by faster roughing

Single tooth cutters generate less frictional heat, which is advantageous for plastics with low melting points

Occlusal surfaces

x060-Rx-xx

x030-Rx-xx

For fine fissures

For extra fine fissures

Basal surfaces

x060-Rx-xx

For finishing fine details in interdental areas of bridges

Cavities

x060-Rx-xx

For finishing narrow areas in cavities, e.g., in anterior crowns

Cavities of inlays / onlays

x060-Rx-xx

For working out narrow areas inside the cavities of inlays / onlays

Cavities in veneers

x060-Rx-xx

For working out narrow areas inside the cavities of veneers

Drill holes

M150-T2-35

For optimal drill holes in cobalt chrome and titanium. Recommended especially for deep drill holes.

x120-Fx-xx

For right-angled inner edges without edge radius

x120-Tx-xx

For right-angled inner edges without edge radius

x060-Rx-xx

For working out fine connection geometries

Note: To manufacture inside edges without edge radii, the optional torus or flat cutters are available.

x060-T-xx

For particularly fine, right-angled inner edges without edge radius (e.g. for connection geometries in drilling ranges)

x050-Fx-xx

For particularly fine, right-angled inner edges without edge radius (e.g. for connection geometries in drilling ranges)

Attachments

x120-Tx-xx

For right-angled inner edges without edge radius

x120-Fx-xx

For right-angled inner edges without edge radius

x060-Rx-xx

For working out narrow areas

Anterior tooth editing (90°)

x060-R2Dx-xx

For working out fine details in the anterior tooth region, e.g., interdental spaces

x030-R2x-xx

For working out particularly fine details in the anterior tooth region, e.g., interdental spaces

General manufacturing settings for material groups

Use this setting to specify the remaining size of partially reduced bars as a percentage.

For an overview of the type of bars and their intended use, see Bar types.

For components such as telescopic crowns, cavities must be particularly precise to ensure a high degree of accuracy. For best results, dentalcnc can interrupt the manufacturing so that you can check the cavities. If necessary, the machine will rework the cavities several times using different sizes until you are satisfied with the result.

This function requires that you be present during manufacturing and operate the dentalcnc computer. Recommendation: Activate this function only if you are manufacturing objects with cavities that require extra high precision.

If you want to reduce the manufacturing noise for all future calculated grinding jobs, activate this setting.

If activated, it reduces the feed rate as well as the tool path distance for grinding jobs. This increases the manufacturing time.

Engraving allows you to add milled labeling to objects. An engraving helps you identify objects after they have been separated from the blank.

Embossing/Relief embossing

The height or depth of the engraving in millimeters:

  • Negative values result in an embossing. The machine mills the text into the surface of the objects.
  • Positive values result in a raised embossing . The machine mills the object so that the label is on the top surface.

The manufacturing determines when objects are fully calculated and manufactured during a job and when tools are changed.

Recommendation: If Per object is preset for a material, leave this setting unchanged. According to our experience, you will benefit from increased process reliability when using these materials.

All objects in parallel (based on tool usage)

All items are calculated and manufactured in parallel.

  • Tool changes are performed based on the tool type.

    The machine fetches a tool and manufactures all objects in the blank that the tool is required for. The machine does not fetch the next tool until the tool is no longer needed for any object. This process is repeated until all objects are fully manufactured with all required tools.

  • Bars are not reduced until the end of the job.

Per object

All objects are fully designed and manufactured one after the other.

  • Tool changes occur on a per-project basis.

    The machine manufactures every object completely with all tools that are required for the object before moving on to the next object. This process is repeated until all objects are fully manufactured.

  • Bars are removed as soon as all the objects to which they are connected have been fully manufactured.

Advantages and disadvantages of manufacturing sequences

Parameters

Advantages

Disadvantages

All objects in parallel (based on tool usage)

Can significantly reduce manufacturing time, especially when optional tools are used frequently.

  • If a tool breaks, the machine may continue to machine with the broken tool for a long period of time.

  • Objects are not fully calculated or edited until the last tool has been used.

Per object

  • If there is tool breakage, the machine detects it more quickly due to the more frequent tool changes.

  • The first items are calculated in advance and can then be checked immediately in the residual material display.

  • The first objects are manufactured earlier.

  • Manufacturing times are sometimes significantly longer because tools need to be changed more frequently.

This allows you to specify the distance that dentalcam aims for between tool spaces during auto-positioning.

Example: 2 mm spacing between tool spaces
