How to Automate SigmaNEST

SigmaNEST decides how much of the sheet becomes money

In a fabrication shop the margin is decided before anything is cut. A sheet of stainless costs what it costs. Whether the parts on it come to seventy percent of that sheet or ninety is a nesting decision, made at a workstation by somebody who may be the only person in the building able to make it.

SigmaNEST, from SigmaTEK Systems, is the software that does the deciding. It nests and programs for sheet, coil and tube across cutting, punching, routing and bending, so one suite drives the laser, the plasma table, the punch, the tube cutter and the brake, and it keeps track of the remnants coming off each job.

Around the nesting sits the rest of the shop: quoting and true costing, inventory, job status, order tracking and invoicing, plus scheduling, part tracking, floor data collection and the quality side.

Steel and the powder coater keep their own hours

A programmer can nest a job in twenty minutes. Getting that job onto a truck takes a week, and most of the week is spent waiting on people outside the building.

The material has to exist. Somebody signs into two or three service center sites to see whether the gauge and grade are in stock this week and what they cost today, because the quote was built on last month's number. Parts go out for powder coat or galvanizing and come back when they come back, and finding out means calling. A customer issues a revised drawing on their engineering portal and the shop learns about it when a part does not fit. Mill test reports for the plate need collecting and filing against the job before it ships.

All of that lands on one or two people who are also the people who program.

SigmaNEST

Material checked before the sheet is pulled Service center stock and pricing read against the grades and gauges this week's nests call for, so a grade nobody can supply this week becomes a different nest instead of a stopped table.

Remnants that get used The offcuts in the rack matched to tomorrow's parts, so the drop from Tuesday's job is cut before a full sheet is.

Finishing status without the phone call Powder coat and galvanizing progress read off each vendor's page, so a promised ship date has something behind it.

SimTrans hands the nest to the systems that will listen

SigmaTEK has built well past the nest itself, and a shop running only the CAD/CAM half is using a fraction of what it pays for.

SigmaMRP takes a quote through to an order and on to the cutting path, so the estimate and the program are one thread rather than two documents. SimTrans is the transaction manager between SigmaNEST and the shop's other business systems, processing and feeding back as things happen. On the floor there is scheduling, part tracking, Shop Floor Manager with data collection, the quality manager and the logistics modules, alongside Load Manager and Color Offload for how parts come off the table. The business end covers quoting, true costing, inventory, job status, order tracking and invoicing, with exchange into an ERP or accounting package.

SimTrans is the tell. It bridges to systems, and it does that well. A steel service center's stock page, a powder coater's job board and a customer's engineering portal are not systems. They are screens that open for a person with a password, and no CAM suite has one.

Remnants and service center stock belong in the nest

A nest built on what a service center actually has this week is a different document from a nest built on hope.

Stock and pricing checked each morning against the grades and gauges the week's jobs call for, so a shortage appears at the nesting stage instead of at the machine. Remnants matched against tomorrow's parts, so the offcut in the rack gets cut before a full sheet is pulled. Mill test reports downloaded as they post and filed against the heat number and the job that consumed it.

Then the work that leaves the building. Powder coat and galvanizing status read off each vendor's page, so a ship date has something behind it. Customer engineering portals watched for revised drawings and new enquiries, since a revision found late is a cut sheet made twice. Outbound freight tracked for the customer who is going to ring and ask. Quotes that have gone quiet flagged by how long they have sat there.

One caution. Reading a portal and building a list can run with nobody watching. Committing a delivery date, or replying to a customer, belongs to a person.

The chasing gets done between programs

The programmer who can squeeze two more parts out of a sheet is the most expensive person in the building to have sitting on hold with a powder coater.

WebRun is an AI agent that works a real Chrome browser, signed in the way your buyer is. It opens the service center's stock page, the finisher's job board or the customer's portal, reads what is there, and lines it up against the jobs and the material SigmaNEST already holds.

It runs on a schedule you set, in your own private environment, and a workflow can be locked to an explicit list of domains. Nothing reaches a customer without a person sending it. Each workflow below names the sites it opens.
