SigmaNEST is the recommended software solution for programming WA Whitney Plasma Punch combination machines.

 

Part Quality

SigmaNEST delivers the highest quality parts through advanced automatic features. Our software provides the tools to produce the most dimensionally accurate parts through the following features:

  • Repositioning control for part accuracy and backlash management
  • Pre-punch start points on plasma applications
  • Appropriate kerf direction
  • Part-by-part punching and cutting
  • Inspection part (first article)
  • Rule-based lead-in technology
  • Punch tool life tracking

Integration

SigmaNEST is an integrated package offering an easy to use and streamlined work method for programmers, estimators, and material management personnel:

  • Directly integrate with Solid Edge, SolidWorks, and AutoDesk Inventor
  • Read geometry files from Unigraphics, CATIA, and Pro/Engineer
  • Supports AutoCAD 2004 DWG and DXF
  • Supports STEP and IGES file formats
  • Automatic feature recognition for special tooling
  • Open architecture allows users to customize post processors and management reports
  • Automated links to MRP software for batch and bill of material processing

Capabilities

SigmaNEST offers several easy-to-use capabilities specially designed for plasma punch combination machines. These include:

  • Automatic part punch tooling - including multi-tool and special tooling
  • Automatic tooling, punching, and cutting assignment for file imported through DXF, IGES, or DWG
  • Automatic nesting of parts between and under clamps resolved through repositioning
  • Automatic adjustment of lead-in lines for positioning the part over the drop door
  • Automatic repositioning of large parts that extend beyond the cutting zone with partial cut pickup
  • Effortless nesting through batch importing and bill of material
  • Supports drilling, tapping, reaming, counter-bore, counter-sink, and pecking
  • Inspection parts hold point

Material Utilization

SigmaNEST creates superior nests and maximizes the use of raw material with the following features:

  • Advanced True Shape™ automatic nesting

  • Combining different work orders on the same sheet for the best possible yield
  • Automatic nesting of parts between and under clamps resolved through repositioning
  • Nesting options available at the click of the mouse button:
    • Grid nest parts
    • True shape nesting of dissimilar parts with interlocking parts
    • Nesting small parts in cut-outs
  • Interactive nesting toolbox to manually manipulate nestings
  • AutoDynamic Nesting™ and tooling for tool load synchronization to eliminate unnecessary tool changes

Motion Optimization

SigmaNEST offers advanced NC programming functions specifically designed for plasma-punch and laser-punch combination machines to reduce machine cycle time and increase cutting efficiency. These include:

  • Automatic tool sorting for miminum cycle time
  • Dynamic cutting condition selection for best performance while mainaining part quality. Optimal feed rate is maintained throughout the cutting process
  • Automatic tip-up part avoidance for head-down rapid move
  • Automatic continuous cutting and pierce elimination
  • Advanced part sequencing functions to create the most optimal cutting path possible
  • Pre-piercing and pre-punching (punching start points)

Material Handling

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

  • Symmetrical tool loading
  • Double punching
  • Smart rapid cleanup avoidance
  • Automated slide moves and drop door operation
  • Temporary stops prior to cropping and part removal

Estimating

SigmaNEST's fully detailed reports provide all the information needed to streamline the cutting operation and provide accurate cost estimates. SigmaNEST can generate:

  • Accurate cycle time estimating
  • Time estimates allow dynamic machine load scheduling
  • Accurate costing and job quotes
  • Tool load management and tool life tracking
