Nested machining

Layout settings: Import the parts that require nesting from this location in the file.

Currently, the formats we support are generally the commonly used STP and a format generated by Tekla’s T2W intermediate plugin.

The automatic application process we configured earlier automatically separates the layers for the flange and web.

The part numbers have also been added using the part names, and this purple section represents an overhead cut, which we configured earlier.

H-beam web path optimization: The straight segment at the bottom of the hole is cut in mid-air; this section corresponds to the straight segment at the hole’s bottom, meaning the cutting head will be aligned with the top edge of the flange during cutting. As for the staggered cut line you can see now, it results from offsetting relative to the weld hole—this is an automated process.
He personally added all the lead wires used in the artwork, including cut compensation.

Let’s go over some layout settings: whatever the part length is, that’s how long the raw material should be.

For example, if the length is 12 meters, you’d enter 12,000—this accounts for material allowances and part spacing. If parts can share a common edge, they will be aligned to share that edge; if they can’t, then…

As for how much clearance he leaves between the two parts, it’s generally fine to set the pipe-end overhang to zero. Regarding the scrap length, we can either support a zero-scrap setting or allow a slightly shorter scrap length—either option is acceptable.

This is the starting point for overlap detection; make sure to select the option that avoids crossing edges. If you don’t select it, there’s a chance the model could penetrate at that location.

This is the cutting layout; this is the bevel at the cut edge. This location does not apply to H-beams—bevels for H-beams are set here.

This is the bevel angle, and this compensation value is set to 0.

Part markings can also be added to the cut edges to make it easier for us to identify them after cutting.

Find two cut ends and join them together—confirmed. Great, now it’s been laid out. Let’s adjust the number of parts and the length of each part.

Let’s demonstrate the cutting and nesting effect; two nesting results are now available.

After completing the toolpath simulation, we need to perform another normal-vector check and optimize the toolpath here based on our tool model, specifically adjusting the R-corner radius.

We can see that the distance from this point to that point is 40, which means the cutting head starts beveling from this point.

To ensure optimal cutting results, we’ll minimize the bevel distance as much as possible; here, we’ll adjust it to 20.

From here to here it’s a straight cut; the turn doesn’t begin until you reach this point.

It’s fine if we perform collision detection and find no interference.

Then we can also run a simulation here to take a look after we’ve finished typesetting and made the necessary settings.

If there are no issues, you can export the ranking results.

Just take it to the machine for cutting, then find a spot to save it.
