What is Nesting Software?

That may be a self-evident question to some, but surprisingly, there are misperceptions about what really is “nesting software,” or, more to the point, what functionality actually defines nesting software.

In this discussion, I’ll outline what basic functions are most commonly found in nesting software, and I’ll parse out what functions you can additionally find in more advanced nesting software.

  1. The Nesting Algorithm (engine)– At the heart of every automated nesting software package is a nesting algorithm (formula) that looks at some quantity of parts then orients them to fit one or more sheets of material.  Interactive nesting seeks to achieve the same goal of putting parts on a sheet of material; however, the user is left to drag and drop or interactively do the thinking that automated software does.  With more automated nesting software, the user can use different nesting strategies such as just in time nesting, kit nesting or batch nesting to gain second and third level benefits (material efficiency, reduced programming time, etc.) Read more …

Answers to Your Common Edge Punching Questions

Common Edge Punching

Common Edge Punching for Turret Punches

Automatic nesting with common edge punching is a fairly recent development on the market.  You may already be familiar with automatic common edge cutting for lasers.  This is a similar concept; however, it is applied to CNC punch nesting.

What is Common Edge Punching?

Common edge punching is the punching of two adjacent parts with one tool hit within a nest.  The idea is to save machine time by eliminating the second tool hit and to reduce material scrap by eliminating the skeleton otherwise between the two adjacent parts.

Dynamic Nesting v. Static Nesting | 6 Comparison Points

Static Nesting vs Dynamic Nesting

Static Nesting vs Dynamic Nesting

What’s the difference between dynamic nesting and static nesting?

They are two nesting strategies frequently used in 2D or sheet metal fabrication.  Both strategies speak to the means and method by which the parts are ordered, arranged or laid out and produced on the laser, punch, plasma, router or other fabrication equipment.

Although they serve the same need of nesting, the differences between the two approaches are striking.

Let’s Review.   Read more …

Automatic Nesting and Automated Nesting – Smart Shoppers Know the Difference

Automated Nesting v. Automatic Nesting

Automated Nesting v. Automatic Nesting

To the uninitiated manufacturing professional the two terms “automatic” and “automated” as they apply to nesting and nesting software can whiz by undifferentiated in a conversation.  That’s perfectly understandable because our everyday experiences afford us no reason to assume there is much difference between the two terms.

Ah, but it is in that distinction where an important mistake is made when it comes to looking at nesting processes and nesting software.  Read more …

Nesting Efficiency Figures – What Everybody Ought To Know

Measuring Sheet Metal Nesting Material Efficiency

Measuring Sheet Metal Nesting Material Efficiency

Here’s A Quick Way To Understand Sheet Metal Nesting Efficiency Numbers

Why Manufacturers Track Material Efficiency

Manufacturers track their material efficiency for a few reasons. They follow efficiency numbers as a means of keeping an eye on day-to-day costs.  They look at variances in their material efficiency numbers to see if any production changes (part mix, sheet size, trim allotment) have made a difference in efficiency.  Finally, manufacturers frequently look at material efficiency as one basis for evaluating the return on investment when sizing up different sheet metal nesting software or CAM packages.

How to Measure Material Efficiency

We  now turn to the task of measuring or calculating material efficiency.  Read more …

Pros & Cons of Single Part CNC Programming

Single Part Programming | Time vs Material

Single Part Programming | Time vs Material

We often hear from manufacturers that they are doing single part programming.  Some do it by design.  Some do it by default.  Either way it is a process that dramatically impacts how your fabrication operation works.  Therefore, it merits a discussion to better understand what it is and how it strongly influences throughput and material efficiency outcomes.

What is Dynamic Nesting?

Optimation Dyanmic Nesting Software

Optimation Dyanmic Nesting Software

There are a lot of terms tossed around to describe types of nesting.  “Dynamic” is one of those terms, and, unfortunately, often its meaning gets lots in translation.

What is Nesting?

First, let’s be clear about what nesting is and is not.  Nesting in fabrication describes the laying out of multiple 2D or 1D-parts in a defined space to be cut from flat stock (sheet metal, composite material, etc.).  Typically, the nesting goals include material efficiency and/or response time / throughput.
