In short

How do I get a weekly scrap rate report from SigmaNEST?

WebRun rolls up every nest SigmaNEST ran in the prior week each Monday and calculates the scrap rate by material and by job. It logs the full breakdown to Google Sheets and posts a Slack summary highlighting the highest scrap jobs compared with the week before, turning a week of nesting activity into one scorecard for your production review.

  • Scrap trends by material and job are visible every Monday instead of once a quarter
  • The highest scrap jobs surface automatically for the production review
  • A full scrap rate history builds in Google Sheets without manual data pulls

Questions, answered

Does it change nesting settings to reduce scrap?

No. WebRun only reports the scrap rate that already happened. Adjusting nesting parameters to improve it is still a decision for your programmer.

How is the scrap rate calculated?

It is the scrap area divided by total sheet area across every nest in the week, grouped by material and by job so you can see where waste is concentrated.

Can I compare scrap rates across months?

Yes. Every week's numbers accumulate in the same Google Sheet, so you can track the trailing average and compare any week or quarter against another.
