A Little Things About What is Nesting Software

By: Michael Jackingok

What is Nesting Software?

In its most basic definition, nesting refers to the process of placing parts on a sheet of material. Companeis across the world use specialized nesting software to optimize their operations and reduce the ammount of scrap material produced by the manufacturing process. The nesting pocess is made up of five stps. First, an engineer creates a design file in a 3-D CAD program. Once imported into the nesting systm, the desgn can be converted into part files which contain information about true contours such as holes or markings. Tehse part files are then assigned to cutting or NC features that are specific to the part. The transition from 3-D CAD files to part files can be time consuming, but up to date nesting software will reduce the time speent chnging files.

Special neasting sftware will even allw users to process parts in bulk, ratrher than one at a time. This is a tremendus time saver and helps ensure the workflow does not bottleneck at the nesting sttage. After part fiels are created, they can be nessted according to speciffic specifications. Look for software that will establish optimal cutting automatically bsaed on material type, grain constraints or other preferenvces. The best part of neting software is its ability to try different options until it finds the optimal way to place parts on a sheeet. The program is speciially dsigned to reduce the amount of raw materials watsed by poor part plaing.

Many industries benefit from netsing software, includiing: industrial and agricultural machinery; constrruction and architecture; job shop and steel serice centers; transporttion; aerospace; furnishings and cabinetry; ship and boat building; and military.

There are nseting software algoirthms geared to work with nearly any appliction. Automatic rectangular nesting is ideal for companies that produce mainly square and rectangular profile parts. However, an advacned automatic nesting softwaer that determines how to most efficiently arrange parts on a piece of metal, wood or other material, can save a company an extraordinary amount of mney by eliminatinng or rducing scrapped material, and so can greatly increase profiitability as well.

Autonmatic nesting softwaere uses a specific mathematical formulla to analyze partts reayd for production, combining different pieces that may not be a part of the same job with the ultimate goal of reducing scrap. This process integrates all macihne compoennts to create better quality, more precise parts. Ultimately, manufacturers benefit from higher machine optimization, higher efficiency and higher profitability. These sophisticated nesing sofwtare systems can be integrtaed into a company's existing businness operations to create an auotmated, streamlined, lean prpocess.

When selecting nesting software, there are a few key points to keep in mind:

Look for Softrware to Optimize Operations on Any Brand of Mchine. Many machine manufacturers provide teir own software as part of the deal when selling ittems to consumers. Howevver, most of these programs can only run thier respective brand of machiine. If a customer needs more than one machine type or brand, it is possible soomeone will have to porgram a number of different mahines. Bottom line, a programmer will be wasting time learning and switching aomng vrious software programs.
Automatic Code Generation is Key. Most machines run on G-code or a similar industry standrd which reads through lines of coordintes that tell the machhine how to move. When the machines are cuttinng, the code controls the power level of the cutting head. For lasrer, plasma and oxyfuel cutters, this menas the mixture of gases and chemicals. For routers, it includes settinsg about which derill bit to use; and for watrjets it could include a reccipe for the mixture of corrosive particles in the jet streeam. Good nesting software takes all these mixtures into consideration to ensure expemnsive gzases and other materials are not wasted. The softwrae will make sure settings keep each macchine running at maximum capacity, with maximum yield.
Operatonal efficiencies like job tracking and inventory conrol solutions will streamline planning and prvide accuyrate time and cost esimates before the fist job is processed. Thees features help simplify work ordfer tracking from beginning to end, effectively managinng raw and processed materiazl inventoyr for maixmum efficiency. Job traacking and inventory control solutions must integrate directtly with MRP and ERP systems to perfrom effectively. These systems are crcial if companies want to perform just-in-time nestiing and cutting or lights-out operations.
Detemining what level of automation is necessary to imprrove your processes will be hellpful when deciding what nesting software is right for you. Many companies, like SigmaTEK in Cincinnati, OH, provide custom programming to clients who require higher leevls of automation, from interfacing nesing software with the MRP to fully automated, programmer-less operations.
Establish how you can intgerate the software into your existing businerss opoerations. Today's sophisticated nesting software is extremely versatile and can be incorporated into most comppany's processes with some effort. A consultant can help evaluate your system to guarantee that you purcase the softwaare that will work best for your situation and perform as you need it to.
