Mirrored Electrode

The Assembly mirror function provides two special options that can only be applied when an electrode is mirrored.  When selecting Copy Electrode Geometry, the entire mirrored electrode is only an import of the normal electrode.  Recreate Electrode Features is a better option if slight editing of the electrode is required. With this option, the mirrored electrode will have its own features of blank, UCS and holder that are not based on the mirror plane.

Burn Body

Burn Body is a significant new function for electrode designers, providing a way to bridge working with surfaces and solids.  Until now, users had to choose between extracting individual surfaces or using a Cut feature on a solid to start an electrode.  In version 13, every electrode can be started with the usual extract of the faces to be burned.  For those who prefer working with a solid, the Burn Body would then automatically surround and trim the burn surfaces into a closed solid object.  The function also has several extension options that can be adjusted to provide for some degree of cavity clearance.

Assembly Construction

When an assembly is exported to a neutral format such as step or iges, the translator will set the internal 0,0,0 point of each file at the location of the file UCS_10.  Often though, UCS_10 is irrelevant to the part and better control is desired.  This is provided by the export parameter Assembly Construction.


Three options are available for this parameter:

Automotive – Sets the 0,0,0 point of each part at the assembly origin.  This provides a way to export an entire assembly where each part references the body coordinate system.

Electrode – Sets the 0,0,0 point of each part where the special Electrode UCS is located.

Electrode NC – Sets the 0,0,0 of each part where the special Electrode NC UCS is located.

Note: in the case of Electrode or Electrode NC, if these special UCS are not found in the part, the system will instead use the active UCS of the part, which is also a good option.

Points on Cone Centers

Anytime a pattern of holes exists, either on electrodes or on common parts such as speaker grills, the hole centers must be referenced.  However, when the part shape is contoured, there is no true circle to provide the center point.  This presents a unique challenge, but one that Cimatron can solve with a special selection filter.  While in the Point function, open the filter dialog and set it to Center and 3D Cone Edge.  This filter not only allows for a box selection of multiple curves, but can also determine the true centers of 3D curves that are not arcs.

Streamline Design with Electrode Blank

Nov 2015 tip 3The Electrode Blank function provides some powerful and unique functionality that streamlines the electrode design process. It can perform look-ahead calculations based on features that appear further downstream in the part history tree.  The Re-center and Re-fit options allow you to adjust the blank location and size while accounting for any extra geometry you may have created for clearance and shape extensions.  A newly-added option is Re-fit Height, which can determine the new top Z level for the electrode based on the finished electrode shape.

Customizing Electrode Reports

Oct 2015 tip 1Electrode Reports in Cimatron E12 are created through the EDM setup screen.  The report is an Excel document that is now based on a default Excel template.  This allows you to easily customize the template to produce reports that fit your exact needs. You will find the default template in the CimatronE12/data/templates/EDM_Report folder.  When making an edit to the report template, you must pay very close attention to the start and end statements at the far right side of the rows.  These set the ranges that allow the setup variables to work and fill in the correct values in the report. Try a few simple edits first, and always keep a safe copy of the default report on hand in case you need to revert to it.

Assembly Mirror

Electrodes are among the most common parts to be mirrored.  The quickest way to make a mirrored electrode is to use the Assembly Mirror function. This function was enhanced in E12 to recognize and ignore the electrode holder and burn UCS.  This allows you to place a correctly oriented holder and UCS as new features in the mirrored electrode file.
