Tech Tuesday: Detect Open Edges

Posted November 16, 2021 3:56 pm   Published by    BobCAD-CAM ">

Tech Tuesday is a weekly blog that addresses some of the most common questions and concerns that I hear throughout the previous week from users of BobCAD’s CNC software. Both customers and future customers are more than welcome to leave a comment on what they would like to see covered for the following Tech Tuesday.

 

The brand new Detect open edge option allows you to control how open edges on selected surface geometry are handled. In the past, features would create a toolpath which brought the tool up to the edge without going over whether the geometry had open edges or not. In order to move the tool over open edges, wireframe geometry had to be created and selected to guide the tool over edges. Now, with the new Detect Open Edges option in the Mill 2 Axis Feature Geometry Picking dialog, simply select the check box to get the tool to move over the open edges, or keep it cleared to keep the tool from crossing those edges. Just another option to save you even more time!

The example shown below is the new geometry selection for the Detect Open Edges option. By selecting the floor surface of the open pocket, BobCAD can now detect the open areas of that pocket. Before, you would have to extract the edges of the surface to become wireframe, then modify the lines of the open pocket to dashed lines for BobCAD to understand where the opening was. No need for all of those steps anymore. Now you just need to select the floor surfaces to be machined, and check the box to Detect Open Edges in the Data Entry window.

The example shown below displays the toolpath when you have Detect Open Edges deselected, then when Detect Open Edges is selected. The first toolpath starts inside the pocket and does not fully pass outside of the opening. This will leave unfinished areas in the corners of this pocket to still be machined away. In the second toolpath, the tool will start outside of the pocket to take care of this remaining material in the corners. The new Detect Open Edges option allows you to use all advanced pocket options, including the high-speed machining options Morph Spiral and Adaptive Roughing.

With the new Detect Open Edges feature, BobCAD now does all of the work of generating an open pocket routine for you automatically!
