Tessnest — from an auger flight's specification to a laser-ready cut sheet
Develops the flat blank of a helical flight, draws it as one continuous laser contour, nests it at high yield with bend lines and marks kept, and exports the drawing.

The problem
Manufacturers of auger flights cut flat blanks from steel sheet and form them into a spiral. Working out the blank's size from the flight's pitch, diameter and thickness is hard to get right, and fitting the blanks onto a sheet is done by hand. Laser machines come with their own nesting, but it fails on custom parts and strips the bend lines and marks from uploaded drawings, so operators end up moving pieces by hand.
What Tessnest does
- Flight designer. Enter the formed diameter, pipe diameter, pitch, hand, thickness and material; it develops the flat blank, with its size, area, weight and the number of blanks needed, and shows the flight in 3D.
- Cut patterns. Draws the blank as one joined contour the laser cuts start to finish: segmented, or a continuous ring with a fine slit.
- True-shape nesting. Nests the blanks — or any part from an uploaded drawing — at high yield, keeping bend lines and marks, with manual adjustment and live checks when an operator wants to move a piece.
- Export to drawing files, with parts lists and sheet counts.

In development with a manufacturer of augers as the first user. Coming soon.
