TubesT - How to Handle Incomplete Web Toolpaths on H-Beam / I-Beam Parts?

1. Scenario Overview

 

To ensure machining safety, the software applies an angle limitation to H-Beam toolpaths. As a result, the following toolpath on the H-Beam web can only extend up to 45° at the R Corner.(For detailed explanation, please refer to the tutorial H-Beam Toolpath Angle.)

Therefore, for parts on the H-Beam web that include features such as tongues, weld scallops, or slots: When the web toolpath angle at the R Corner θ < 45°, the Follow Cut toolpath can be generated normally. When the web toolpath angle at the R Corner θ > 45°, the corresponding web toolpath will be white-out by the software.

2. Solutions

 

For this scenario, depending on machine and processing requirements, there are three available solutions.

You may first identify the scenario that applies to your machine, then click the Quick Jump link to directly navigate to the corresponding method.

 

Scenario Method Solution  Workpiece Quick Jump

Machine supports Fixed height cut

Use Fixed height cut for toolpaths where θ > 45° at the R Corner

Use Optimize H-Beam End Toolpath】, set Cut method to Follow Cut + Fixed height cut

H-Beam

Method 1

Machine does not support Fixed height cut

Generate Follow Cut toolpath at θ = 45°

Use Optimize H-Beam End Toolpath, set Cut method to Follow Cut

H-Beam

Method 2

Modify the original drawing so features are below 45° at the R Corner

H-Beam / I-Beam

Method 3

Steps:

Import the part. After performing Collision-Avoid, click Optimize H-Beam End Toolpath.

Note: Optimize H-Beam End Toolpath is an exclusive feature of the Steel Structure Edition.
If the option is not available in the toolbar, please refer to the tutorial 《Enable Steel Structure Features》 first.

② Set the Cut method to Follow Cut + Fixed height cut. Configure the parameters as needed, then click OK.
