Edge Deburring Recognition 2021

Introduction to Edge Deburring Operation

Overview of Edge Deburring Operation

• The video introduces the edge deburring operation in SolidCAM, which allows users to apply a deeper edge break or chamfer to all edges of a solid in one tool path.

• Users can access the edge deburring recognition operation through the SolidCAM operations menu or by right-clicking on an existing tool path.

Geometry Selection Process

• The recognition toolpath enables automatic selection of geometry; users can choose between selecting a solid body or individual faces for processing.

• When selecting a solid body, the system identifies horizontal faces and their edges but excludes edges of holes based on minimum diameter filters set by the user.

• Users are advised that certain edges, such as those leading into existing chamfers, may not need additional deburring.

Advanced Geometry Filters

• The toolpath offers options to ignore specific edges, such as those leading to fillets or angles less than 90 degrees, enhancing precision in selection.

• By adjusting selection modes (solid body vs. face), users can refine which edges are included for deburring based on their design needs.

Tool Path Control Features

• To prevent gouging during machining, users can define protection parameters within the main window settings for 3D model protection.

• A distance value can be set to keep tools away from targets during operation, ensuring safety and accuracy.

Tool Selection and Depth Settings

• Users select tools from a toolkit; customization is possible by creating new shapes from solid models. Reference materials are available for guidance on this process.

• In defining levels for recognition, users specify how much of the target they want to recognize with upper and lower level settings adjustable according to project requirements.

Chamfering and Edge Deburring Techniques

Overview of Chamfering Process

• The process involves a type of chamfering referred to as edge deburring, utilizing the shape of the tool to generate a chamfer.

• A default setting of 50 thou is used, determining how far the tool tip will be positioned from the cutting diameter during operation.

Tool Movement and Cutting Parameters

• The operation can follow specific chains precisely, allowing for either climb or conventional cutting directions based on tool selection.

• Feed rates can be adjusted when approaching corners; previous tool sizes and wall offsets help determine material presence in corners.

Safety Measures and Gouge Checking

• A safety offset dimension is set to maintain distance between the tool's full diameter and any edges or walls of the part being machined.

• Additional gouge checking measures are implemented to ensure that tools do not collide with walls while performing operations.

Minimum Edge Length Considerations

• Users can specify a minimum edge length to ignore small edges that may not require machining, preventing unnecessary cycle time waste.

• This feature helps avoid repositioning tools for minimal edge work that does not contribute significantly to the overall machining process.

Final Adjustments and Verification

• Control over feed rates allows for ramping in lead-ins and lead-outs similar to profile operations; adjustments are made before saving calculations.

• The software generates deeper operations based on selected geometry while ensuring no collisions occur with existing features like bosses or walls.

Analysis of Deburring Results

• After processing, it’s noted that some areas were intentionally left untouched due to potential collisions; this includes certain bosses where depth was too great.

• Solid verification shows effective deburring along edges while acknowledging that these modifications were not part of the original design intent.

Conclusion and Support Information

• It’s important to recognize that deburred edges may register as gouges depending on settings; users should consider this in their analysis.
