Tubest - Modifying Drawings for Curved Bevels on I-Beams

Ⅰ. Introduction

 

Since laser beams travel in straight lines, they cannot process curved surfaces on thicker sections, such as those formed by cutting away circular tubes or arcs.

Because such bevel vectors may be misidentified, collision checks must be performed using a 3D cutting head, and drawings must be processed to create machinable flat surfaces.

Web Surface Curved Bevel Flange Surface  Curved Bevel

 

 

1. Web Surface Curved Bevel

 

Click 【Cancel Bevel at H-Beam Web】 to obtain the Vertical-cut vector.

 

 

Note: A common point of confusion is that the flange section of such parts features a vertically cut arc. Since the flange itself lacks a surface bevel, only the vector's orientation needs verification.

 

 

 

2. Flange Surface Curved Bevel

 

Modify the original curved extruded body to use straight polygons for cutting, as shown below. This yields two outcomes:

 

 

Less Material Effect: Everything within the box is cut away, resulting in a part with one fewer surface triangle than the drawing.

 

Extra material effect: A small sector outside the box remains uncut and is retained on the part. Only the area within the box is cut away, resulting in a part with one additional small sector compared to the original drawing.
