Automatic Conformal Cooling Curve : Options and Results

Automatically create conformal cooling curves by analyzing the part's geometry.

Part on which the function is to be performed

Required Step 1

1. Pick the active faces that need to be cooled. The following parameters are displayed:

   Faces /	A toggle option to select the required faces. Pick face(s) from a single B-rep body.
   Facets	A toggle option to select the required facets (triangles). Pick facet(s) from a single mesh object. See Facet Selection for a description of the various facet selection options.
   Expand to Same Color Faces / Do not Expand	This is a toggle option that enables the selection of faces to be expanded to those of the same color as the first selected face.
   Expand to Same Color Faces	In this mode, when a single face is selected, the selection is expanded to adjacent faces of the same color as the selected face. Example:Example:
   Do Not Expand	In this mode, when a single face is selected, the selection is not expanded to the adjacent faces. Example:Example:

Required Step 2

1. Set the cooling parameters and pick the In/Out points if required. The following parameters are displayed:

   Set the parameters	Pick two points for the cooling circuit which will be labeled as In and Out; these are the in and out points respectively for the cooling circuit.

   A direction arrow is displayed defining the printing direction. The default direction is the Z direction of the active UCS.

   Screen Parameter Options
   Cooling Diameter	Preset the required diameter of the cooling channels that are to be created using the Conformal Cooling Design function. The last used settings are kept and are used for subsequent operations. Default = 5 mm (0.2 inch) Minimum = 0.1 mm Maximum = 100 mm
   Safety Distance	Preset the required safety distance from walls. The last used settings are kept and are used for subsequent operations. Default = 5 mm (0.2 inch) Minimum = 0.1 mm Maximum = 100 mm
   Min. Distance Between Cooling Channels	Preset the minimum required distance from other cooling channels. The last used settings are kept and are used for subsequent operations. Default = 5 mm (0.2 inch) Minimum = 0.1 mm Maximum = 100 mm Note: The Min. Distance Between Cooling Channels value should be ≥ the Safety Distance value. If it is less than the Safety Distance, the Min. Distance Between Cooling Channels value is displayed in red.
   Detect Proper Parameters	Click this option to enable system-defined parameter settings to achieve the desired result. This option is displayed if the selected cooling faces are detected by the system as walls with almost the same thickness. When this option is selected, the system automatically adjusts the parameter values to achieve optimum results and the Vertical/Horizontal option is displayed. The Detect Proper Parameters option is then dimmed and will be enabled again if one of the detected parameters is changed. See the examples below. Example:Example: Selected cooling faces are detected by the system as walls with almost the same thickness When the Detect Proper Parameters option is clicked, the system automatically adjusts the parameter values to achieve optimum results
   Vertical/Horizontal	This is a toggle option to create the conformal cooling circuit either Vertically or Horizontally. This option is displayed if the selected cooling faces are detected by the system as walls with almost the same thickness and after the Detect Proper Parameters option is clicked. Example:Example: Automatic conformal cooling circuit created vertically Automatic conformal cooling circuit created horizontally

Optional Step 1

1. Pick additional closed object(s), such as cooling channels (even if they were not yet cut with the part), to make sure that the created cooling curve circuit stays further away from them.

	Closed object selected

Optional Step 2

1. Pick a closed object that defines a virtual volume used to split the cooling circuit into several circuits. The circuit may be created either inside or outside the virtual volume.

   		Virtual volume used to create several circuits

   Screen Parameter Options
   Channel Inside Virtual Volume / Channel Outside Virtual Volume	This is a toggle option to create a circuit either inside or outside the virtual volume of the selected object. Example:Example: Circuit Inside Virtual Volume Circuit Outside Virtual Volume
   Channel Inside Virtual Volume	Create a circuit inside the virtual volume of the selected object.
   Channel Outside Virtual Volume	Create a circuit outside the virtual volume of the selected object.
   Keep Virtual Object / Remove Virtual Object	This is a toggle option that enables the virtual object to be kept or removed from the operation. Example:Example: Keep Virtual Volume Remove Virtual Volume If the virtual object is not in the active part, this parameter is displayed as Keep Virtual Object and dimmed.
   Keep Virtual Object	Keep the selected virtual object. This is the default option.
   Remove Virtual Object	Do not keep the selected virtual object.

2. Click OKOK or ApplyApply in the Feature Guide to complete the function. The system will then calculate the optimal path of the conformal cooling channel and create a curve to be used as an input for the Conformal Cooling Design function as shown below.

When completed, the Auto Conformal Cooling Circuit feature will appear in the Feature Tree as follows:
