Dynamic Optimization Means Precise Cutting with Less Waste

What Is Dynamic Optimization?

Dynamic Optimization software from TigerStop, also known as linear nesting, is an instant and mathematically precise way of deciding what order to process parts to optimize material yield.

Does Order Matter?


The order in which you cut your parts from your stock material can have a dramatic effect on your overall material yield.

Consider this example: I am making a frame out of square stock, basically a rectangle box. I want to make it 5.5 feet wide and 1 foot high. So I need 4 pieces at 5.5 feet and 8 pieces at 1 foot to complete the frame. My stock comes in 10-foot lengths. Let’s look at the ways to lay this out.

I could follow the list exactly, which would leave me with 3 lengths of stock at 10 feet each and 11 feet of waste.


Dynamic Optimization Cut Ratio


Or I could optimize my material like the below example. Here I use 2 pieces of stock and have only 1 foot of waste.



TigerStop’s Dynamic Optimization software will quickly figure out the best order to cut your parts so you always get the best material yield.

How Does Dynamic Optimization Help My Business?

  • Dynamic Optimization software determines the best use of material so the operator (unskilled worker or pro fabricator) only has to focus on feeding parts and cutting.
  • TigerStop moves to the correct position up to 0.004-inch so the operator never has to use a tape measure or set a manual stop ever again.
  • TigerStop reduces station setup time between different cut lengths and allows the operator to optimize for defects like forklift stabs, shipping damage, dents, or aesthetic blemishes while getting optimal yield.
  • Dynamic Optimization reduces scrap waste and shelving costs. Purchase less raw footage while sending fewer pounds back to the recycler.
  • TigerStop increases accuracy. The operator doesn’t have to worry about cutting errors or the associated costs of rework. Quality control concerns are no longer a bottleneck.
  • A TigerStop Dynamic Optimization station can even be used by an unskilled worker. Top-paid fabricators and skilled workers can better use their time managing the shop or doing work requiring greater expertise.

How Does Dynamic Optimization Work?


Here we run through the process on an upcut saw. You can use Dynamic Optimization with many other applications as well.

  1. First, the operator enters his cut list into the TigerStop. He can do this manually or using the Cut List Downloading software upgrade. Then he presses the Done button.
  2. The operator enters a cut list and the material length, and the Dynamic Optimization software will determine which part to cut first to give him the least amount of waste.
  3. Finally, the operator then simply makes the cut, and the stop moves to the next position. He doesn’t need to do any complicated math or cut in order of largest material to shortest.

When using Dynamic Optimization on a backboard fence, as pictured below, the operator can also defect parts, that is, remove imperfections and flaws and get the best yield out of the remaining stock. This process is called Backboard Defecting.

If there’s an aesthetic defect in his material or a forklift stab, he simply enters the distance from the trim cut to his first defect. TigerStop’s Dynamic Optimization will use its proprietary algorithms to find the best yield of the material with the least amount of waste and move to the correct position.

The operator feeds stock to the TigerStop. When the operator reaches the first defect he cuts it out and enters the next usable clear length. He continues to make cuts until stock completion, only moving material and cycling the saw. He repeats until TigerStop indicates the job is done.
