Outline

  • Define when a calculator estimate needs a coupon verification.
  • Specify coupon size, material lot, grain direction, tooling, and bend angle.
  • List measurements: thickness, flat length, leg dimensions, inside radius, final angle.
  • Explain how to store the accepted setup for the next job.
