What Makes Dynamic Nesting “Dynamic?”

What Makes Dynamic Nesting "Dynamic?"

Dynamic Nesting is one of those ubiquitous terms that often has different meanings depending on who you are talking to and what their previous experiences have been. The term “dynamic” can point to three different attributes of the nesting process – 1) the shape and variety of parts, 2) the management of due dates and priorities, and/or 3) the mixing of  orders.

Mixed Part Shapes
Most commonly, dynamic nesting is distinguished from static nesting by the ability to nest many parts of different sizes and shapes.  There may be ten, twenty, or fifty parts on a sheet or nest, but there may be up to an equal number of different parts.  “Dynamic” in this case means the combining of large and small, round, rectangle, obround, and any other shaped part in one sheet of material to achieve an optimum fit.  The user in this scenario is focusing on optimizing material efficiency.

An Easier Way to Get 95% Nesting Material Efficiency

Material Waste - Programming Time - Inventory Expenses

Material Waste - Programming Time - Inventory Expenses

I recently heard about a manufacturer, who had an extraordinary material efficiency.  They consistently got 90-95% material efficiency on every sheet they ran.  Further, this was achieved with exceptionally complicated patterned/grained material.  It was an amazing feat!

First I’ll tell you how they did this and the problems they encountered.  Then I’ll walk through an easier solution.

How did they get the material efficiency?

The first question is, naturally, how did they do it?  They could be doing manual nesting and spending a great deal of time on each nest, but that’s only half the equation, they still need the right part selection to make a highly efficient nest.  They could be running lots and lots of the same or rectangular parts which lend themselves to static nests with high efficiency.  Or they could be making very large sheet-sized parts that have very little waste.

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.

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.
