Automatic Nesting

Real Automatic operation, including "lights out nesting"

No manual intervention to achieve exceptional results

Get results in minutes that would the best programmers several hours to match

Programmers have used computers to nest parts for many years. They check multiple rotations of the parts, and nest the best rotation in rows and columns. Time was the limiting factor for the programmer and to this day, nesting in rows and columns is the most effective way of nesting.

PEP analyzes and then categorizes the parts. and then nests the parts in memory, mathematically evaluating the options, possibilities and constraints while analyzing almost every possible combination of parts in rows and columns. 

The advantage that PEP has over the programmer is speed. An experienced programmer will typically look at the parts and make a decision on which way might be best.  If the results are within acceptable limits, then he's usually done.  PEP can compare more parts, layout variations, check thousands of rotation combinations, and therefore get to a nest that is "most acceptable" very quickly.

The advantage PEP has over other automatic nesting products is the proprietary way that PEP can analyze and categorize the parts, and theorize the nest.  Then PEP will check all viable combinations to arrive and that one nest it presents to the programmer.

Proprietary Nesting Engine

Proven Technology provides Competitive Advantage

Extensive Industry Expertise with detailed understanding of metals and machines

Great Results with improved yield, run time and quality

PEP Technology made a decision over 30 years ago to write its own nesting engine.  While many nesting tools use the same commercially available nesting engine, PEP's is proprietary and highly specialized.  It's one of the reasons that our nests are tighter, providing better material utilization than others.

Competitor Approach

Other automatic nesting products require the operator to select the nesting mode based upon their experience with the nesting software and the type of part being nested. When nesting multiple parts this single mode must work for all the parts throughout all the plates. The nesting results are then accepted or rejected based upon what the operator perceives, and whether another mode can do a better job. At best, this approach only works some of the time, and almost always requires editing of the nests to get an acceptable yield.


How many programmers does it take to run your automatic nesting software?  Why?


Most nesting tools depend on the efforts to an experience programmer to get expert results.  The software does the basics and the programmer manually improves the nest.

PEP takes a much smarter approach:  Let the software do it.  Why expect the programmer to understand heat dissipation when the software can do it automatically?  When depend on the programmer to understand the features and strengths of your machines when the software can do it automatically? Why depend on the programmer to sequence the parts for optimal speed when the software can do it automatically.  

If your nesting solution depends on the programmer to get good results, is it really automatic nesting?

Material Yield Savings

In a recent comparison, PEP nested 76 parts. Competitors nesting products using their push and shove concept nested only 63 parts, and the Manual Gridding approach only nests 56 parts. The material savings using PEP can be more than 30% on some nests.

Machine Productivity

PEP reduces rapid travel distances and eliminates head raises resulting in a 15% to 25% increase in machine productivity. Since the machine time is far more expensive than the material, the benefits of PEP’s automatic nesting as it applies to machine productivity needs to be understood.
