Burn Body: Options and Results

Note: This function is only available when an electrode is active in an Assembly environment.

The function has several extension options that can be adjusted to provide cavity clearance. The Burn Body and Solid Extension functions enable you to create a body and extend it all the way up to the electrode base. Together, these functions can be used to create electrodes using solid tools.

Required Step 1

Pick the burning faces around which the body (or bodies) will be formed.

 

By default, the system automatically selects all the burning faces of the electrode that do not have a body on them and jumps to the next stage. However, you can return to this stage and change the selection. If no burning faces are found automatically, the system remains in this step until the burning faces are manually selected.

 

The burning faces (in RED) are automatically selected, and a body around each lump is displayed.

If the burning faces are manually selected, click exitexit(middle mouse button) to continue to the next step.

 

The examples above show a multi-lump (multiple burn area) electrode (by proximity, faces that touch each other are considered to be in the same lump). The burning faces for each lump are automatically selected and a box around each lump is created along the directions of the electrode extraction or blank if it exists. The box is previewed with default or last used offsets (see the next stage).

Required Step 2

Define the way the body (or bodies) will be built around the faces. The direction arrow is displayed to define the extension direction.

 

A box around each lump (of burning faces) is created along the directions of the electrode extraction or blank if it exists. The box is previewed with default or last used offsets. Set the screen parameters as required.

The following parameter options are available.

Press OK or Apply in the Feature Guide to complete the function.

When completed, the Burn Body feature will appear in the Feature Tree.

Parameters

Optimized Rectangular / Rectangular	When creating a Burn Body, Cimatron first creates a solid box around the extracted burning faces. This box can be created as Optimized Rectangular (the default option) or Rectangular. Optimized Rectangular This option is similar to the Rectangular option listed below, however, it makes the burn body on an angle relative to the EDM project origin. The box is rotated so it is as tight as possible to the burning faces. This is the default option. Rectangular This option makes the burn body rectangular and relative to the EDM project origin.  Rectangular Optimized Rectangular
Cut: Single Direction / Cut: 2 Directions / Cut: 3 Directions / Do Not Cut	Set the electrode type from the dropdown list of the options (for each type, the extension direction(s) are automatically recognized). Cut: Single Direction The electrode will be extended in a single direction. This is the default option. ExampleExample Cut: 2 Directions The electrode will be extended in 2 directions. ExampleExample Cut: 3 Directions The electrode will be extended in 3 directions. ExampleExample Do Not Cut The electrode is created, but without an automatic cut operation. This option allows you to create a burn body without cutting it. It is ideal for when the automatic cut options listed above do not produce the best results.
Single Plane for All Lumps / Multiple Planes	Toggle option that enables you to position the lumps on single or multiple planes. This option is displayed only if more than one lump is detected. The default value is set in Preferences, however, the last used value for this parameter is always displayed. Single Plane for All Lumps The lumps will be positioned on a single plane. The top face for all lumps is created on a plane normal to Z and moved in the Z direction the distance defined in Minimum Distance from the highest point on all lumps. See the examples below. This is the default option. Multiple Planes The lumps will be positioned on multiple planes. The top face of each lump is created on a plane normal to Z, moved in the Z direction the distance defined in Minimum Distance, from the highest point on each lump. See the examples below. ExamplesExamples Single Plane for All Lumps The top face for all lumps is created the Minimum Distance from the highest point on all the lumps. Multiple Planes The top face for each lump is created the Minimum Distance from the highest point on each lump.
Minimum Distance	Set the minimum distance of the top face(s) of the solid body (or bodies) from the highest point on the lump(s) towards the electrode base. The actual distance will depend on the toggle Single Plane for All Lumps / Multiple Planes option selected. The default value is set in Preferences, however, the last used value for this parameter is always displayed. ExampleExample
Bottom Offset	Set a bottom offset to the burn body or bodies. The default value is set in Preferences, however, the last used value for this parameter is always displayed. ExampleExample
Lateral Offset	Set a lateral offset to the burn body or bodies. The default value is set in Preferences, however, the last used value for this parameter is always displayed. ExampleExample
Draft Angle	Add a draft angle to the solid body (bodies). This parameter is displayed if either the 2 Directions or 3 Directions option is selected above. The default value is 0. For 2 Directions, the draft angle is added to the open side direction directly on the solid body. For 3 Directions, the draft angle is added to both open side directions directly on the solid body. ExamplesExamples 2 Directions / 3 Directions Draft Angle = 0 2 Directions Draft Angle > 0 3 Directions Draft Angle > 0
Apply Template / No Template	Toggle option that enables you to apply a predefined electrode template to the electrode while it is being created. Apply Template is the default setting. See Loading (Applying) an Electrode Template.
