SigmaNEST per Ossitaglio

Qualità dei Pezzi

SigmaNEST permette pezzi di alta qualità grazie a funzioni automatiche avanzate. Il nostro software vi fornisce gli strumenti per produrre pezzi dimensionalmente accurati. Ciò è permesso grazie a:

• Automatic cut sequencing to minimize thermal distortion
• Automatic lead-in and lead-out definition from built-in technology database
• Previous cut pick-up to minimize piercing thick material

Integrazione

SigmaNEST èun pacchetto integrato che permette un metodo di lavoro semplice e veloce per programmatori, commerciali ed ufficio acquisti. Il sistema offre:

• Interazione diretta con Solid Edge, Solid Works ed AutoCad per mezzo di OLE automation
• Supporto per DWG (AutoCAD 2000), DXF e fle formato IGES con mappatura dinamica dei layer ed assegnazione automatica dei processi da layer o colore. Un esempio può essere marcatura sul layer "MARCATURA" e taglio sul layer "TAGLIO".
• L'archtettura aperta consente di personalizzare post processors e stampe per management e gestione
• Collegamento a software gestionale MRP per ricevimento automatico di distinte base ed ordini di lavoro
• Feedback dinamico dello stato ordini

Capabilities

SigmaNEST is the leading CAD/CAM system for programming multi-torch Oxyfuel profile cutting machines:

• SigmaNEST supports machines equip with automatic torch spacing. If torches have to be set manually SigmaNEST provides the operator with spacing information.
• SigmaNEST features edge burning capability, which begins the cutting process from the edge of a thick plate. Edge burning is also established between parts in a nesting layout without damaging existing part edge. This function avoids costly pierces, saving time and money.
• In automatic true shape nesting layouts may be composed of parts-in-parts and/or interlocking parts.
• Tip-up part avoidance is cutting logic that ensures that the machine head will not pass over previously cut parts. The function automatically determines the cutting order for the parts in a nesting layout to achieve this. One of the very significant benefits of this function is that it allows unattended cutting.
• The work order tracking function allows different work orders to be placed on one plate. SigmaNEST tracks leftover quantities of parts so that they can be nested on subsequent sheets of similar thickness. Our software allows the operator the freedom of mixing orders without losing parts.
• SigmaNEST provides an optimal nesting layout though automatic true shape nesting on irregularly shaped remnant material. This function can be used on singular and multiple torch machines.
• SigmaNEST easily and fully supports manual and automatic machines with a triple torch bevel arrangement.

Material Utilization

SigmaNEST creates superior nests and maximizes the use of new and remnant material through the following features:

• Advanced automatic nesting combines the features of interactive pre-nesting, automatic pre-nesting and multiple nozzle nesting
• Capable of nesting 1,000 parts on six sheets in 7 seconds on a Pentium IV 1.8GHz
• Automatic true shape nesting on irregularly shaped remnant material on machines with single and multiple nozzles
• Advanced Multi-torch nesting
• Common edge cutting
• Full utilization of "drops" on remnant material
• Automatic cropping and scrap cut functions reduce skeletons into manageable peices and remnants into manageable shapes
• Complete raw material inventory control–including remnant tracking
• Nest large volumes of parts effortlessly through bill of material processing function or MRP interface

Motion Optimization

SigmaNEST's advanced NC programming technology reduces machine cutting cycle time thus improving machine throughput by up to 20%. Automatic common line cutting, chain cutting, and other techniques of pierce minimization not only reduces cutting time but results in increased material utilization and consumable life. Contact SigmaTEK for cutting study results from different companies.

• Common line nest example
  

  

• In approximately 3 out of 4 programs tested, SigmaNEST was able to reduce the cutting cycle time by between 7% and 28%

Material Handling

SigmaNEST ensures easy and safe handling of "skeleton" and remnant material by the operator through the following features:

• Automatic priority nesting
• Automatic cropping and scrap cut functions reduce skeletons into manageable pieces and remnants into manageable shapes
• Automatic tip-up part avoidance
• Customized reports, including labels with part image and bar codes to facillitate tracking through the secondary manufacturing operations

Preventivazione

I databese delle icone e dei nesting di SigmaNEST contengono informazioni che possono essere usate per calcolare accuratamente i costi di produzione delle icone. Precisamente, SigmaNEST determina e memorizza:

• Lunghezza totale del percorso di taglio
• Peso netto dell'icona
• Peso del materiale non usato e dello sfrido
• Numero di sfondamenti
• Process based nominal feedrates
• Quality based feedrates

Nel layout del nesting sono disponibili tutti i parametri necessari per calcoli accurati: numero di cannelli, tempo di riscaldo e sfondamento, numero di lastre richieste e tempo di taglio. Il tempo di taglio è calcolato considerando le accelerazioni ed i rallentamenti della macchina.

I costi sono calcolati su un modello stabilito dall'utente e le icone di conseguenza possono essere preventivate con un massimo del 5% di errore.

Una affidabile preventivazione è ovviamente essenziale per essere competitivi e proficui allo stesso tempo.
