Looks like we all like this example and all of us want something more.

Thanx anyway for this….

Hello, first time here. Dick Kusleika – I work in framing industry and am very happy to find your cutting stock length program. Would you consider adding a few modifications to better fit my needs? I would be grateful and more than happy to pay you for your time.

Hello, first time here. Dick Kusleika - I work in the steel fabrication industry and could use your stock cutting VBA to some degree. What I would like to know is would it take much to have it tell me which pieces of which length to cut from each stock length. i.e., 2 pieces 18' 6? long to cut from a 40' 0? stock length piece. I would be dealing with hundreds of pieces of varying lengths from 1' 0? to 58' 0? being cut from 20' 0?, 40' 0? and 60' 0? (various quantities of each) stock lengths as well as several random stock lengths left over from previous jobs.

Thank you, Ed

Hi Simon. I would be interested in your Algol solution. I happen to like OR when I was in school and am curious to see your solution. I hope you can find it and share it. Thanks for your time.

Back in my University days our Operational Research Mathematics class (Dr Lynn was our lecturer if I remember correctly) was set the task of using linear programming and/or trim loss theory to work out how to minimise waste for a carpet manufacturer.

Obviously they sold rolls of carpet in various lengths and widths but cut from one roll.

I did come up with a neat solution in Algol but have never had the need to use it again (or translate it into any other language).

Professor George B. Dantzig invented the the "simplex method" and "linear programming" whilst at Stanford, so if you need more information look it up on the web!

Alternatively, email me and I might be able to find the Algol program!!!

Measure once, cut twice, swear three times…

No am not making Scandinavian furniture but with a 1/8? saw blade and if you have 36? stock and want three 12? boards you would end up with two 12? and one 11 3/4?. If you are making anything, except maybe “rough” framing a house that is a big deal. And of course the longer the stock and the more cuts you make or a wider saw blade, this becomes more of a problem.

The width of a saw blade? What are you making, Scandinavian furniture? It might be good to have a generic waste factor in there. The user could enter either a percentage or a hard measurement and that could be added to each cut, or rather subtracted from the remaining stock after each cut.
I thought about tracking the waste, but never got around to doing it.

Dick, this could be very useful, but what about the amount of wood you lose with each cut? Needs to have a place to put how wide the saw blade is to account for this in each cut you make on a board. As you said it would be better to have the results put on a sheet and maybe even the “waste” that is left in each board, just a thought
