I have to cut a whole bunch of pieces of known length from several lengths of stock. What I need is some software which will run on a Windows box which can take as input the piece lengths I need and also the material length (often 20') and tell me how many lengths of material I need to order and what size pieces to cut out of each piece of stock. That's actually a variant on the "Knapsack Problem", which is one of the standard problems we use to teach advanced algorithms. It turns out that there are pathological cases for which no better solution is known than just trying all the different possibilities and seeing which one works best. Kinda like calculating intersects. For some there is no exact answer, just the level of precision you require? I was going to order 15 lengths of 1x2x.120" rectangular stainless grade 304 tube. Then I got Marv Klotz's software, and found out I can get by with 13, plus it gave me the exact cut list to give to the sawyer. Saved me over $300 just for asking! Grant I'm pleased to hear that it worked for you, Grant. Regards, Marv Home Shop Freeware - Tools for People Who Build Things http://www.myvirtualnetwork.com/mklotz |
