How to fit Rectangular Material in a Tri-Clamp Lathe

thingiverse

Let suppose you have a rectangular shaped (rest of) material, you want to produce a cylinder or tube of that same material, and want to do so asap and with the least amount of waist as possible...on a tri-clamp lathe... Then this calculation tool might come in handy: - enter the rectangular dimensions - enter if you will be using a corner profile in case of soft material In the Excel-spreadsheet and in the FreeCAD spreadsheet the clamp extra's will be calculated, and shown visually (also in a technical drawing). I have used it to maximize the amount of PTFE rings from a circular-segment-shaped block. Limit to the calculation is if the rectangular height is more than twice the width...then you should cut/saw the piece length-wise.
