Sheet yield calculation software?

Andrew Lenz Jr.

MGF, Master Grumble Framer
Anyone use software that calculates best yield from given sheets sizes? There are programs available where you can input the yield sizes and the source sizes and have it spit out the best way to cut the sheets.

For instance, a customer comes in with maybe 30 lites of different UV glass sizes (3 of this, 9 of that, 5 of this, 4 of that, etc.) . . . what's the best way to get them out of assorted glass sheets sizes?

I'm wondering if anyone has messed with any of the yield calculation programs out there.

Anyone?

I use an organic software that I got for free. Sometimes it works and sometime it doesn't. You get what you pay for I guess. lol

Seriously though, I doubt most of us here would ever be able to affordable software so specialized. I know my acrylic provider has it on his cutting saw system, but that saw system is pretty pricey for an average or even an above average frame shop budget.

My print rip does it, and so does the new pool function on the Valiani software.

It would be great to have a little standalone app for that. I'm pretty good at figuring it out manually, though. I just make little sketches of the board size and start drawing in my mat sizes.
:cool: Rick

Hey, Mo. What free program are you using?

I recently found this free program but haven't had time to investigate it:
http://www.delphiforfun.org/Programs/CutList.htm

Rick, there are some mobile device apps for doing it, but I was trawling for possible others' experience.

It can be done manually—especially when we're just talking matboard—but when you are talking a bunch of yield sizes and a bunch of possible source sizes (8x10, 11x14, 16x20, 18x24, 20x24, 22x28, etc.), an ideal solution (or close to ideal) gets VERY complex very quickly. It branches out and becomes like chess with a high number of possibilities.

Granted, an ideal solution is not required, but the farther we get from ideal, the more money it costs us. One of my staff was figuring out how to cut an big order out of the available sizes of UV glass and if I hadn't have stepped in and given her some suggestions, it would have cost us at least an extra $50-$100 in waste. The order would have gotten done, but . . . $$$.

The calculation part of it is pretty well developed already. It's used extensively in the woodworking business for cutting sheet goods.

Hand inputting possibly dozens of precise sizes will be labor intensive, and accuracy is critical. You will also need a way to identify each piece of cut glass as to which job/piece it goes to, so that's more entry labor.

For those two reasons, such a feature would be best integrated into your POS, where you could select a particular order (or set of orders, such as "all jobs being fitted today") and all the info is already there. I don't know how "accessible" the database of a typical POS is, but unless you could connect to it it seems like it would be a lot of work.

For particular jobs it would be no doubt worth it, such as where you have:
30) 15 x 23
20) 21 x 27
15) 25 x 34
etc.

But when you have a list like
1) 14-7/8 x 21-3/4
1) 14-1/4 x 22-1/2
1) 15-1/2 x 20-1/8
etc.
How much time are you going to take checking and double checking the sizes?

For onesies/twosies you will also need a way to generate labels of some sort (printer capable post-it notes or something) to identify each piece of glass.

I think it's a great idea, and has potential to save a lot of time and money, but really needs to be connected to your existing data. POS companies would do well to consider adding such an option.

As Mo said "you get what you pay for". If you have potential to save hundreds of dollars, it may be worth spending a few hundred. A quick search for "sheet good optimizer" shows a bunch of options that are not that expensive. Top of the list is http://cutlistplus.com/ that costs from $40 - 500 based on features (including CSV import of jobs and materials list with costs/sizes), and offers a free trial. Might be worth looking into.

Thanks, David. And I agree. In the case I'm thinking about it's the first of your two scenarios, repeats of about 5-10 sizes, not 1 of this, 1 of that.

Cut List Plus was one of the programs I ran across when I was poking around the WWW last week. Looks pretty good, again, just hoping a framer out there had firsthand experience with one.

QImage, though it's a print utility/RIP, has a decent ability to lay out images for printing that is essentially the same process is laying out for cutting. Plus it has all that printing capability, all for $69.

Pat, the few programs that I investigated take this into account. I specifically checked for this when I was reading a few of the programs' websites last week. Some are designed to work with laser/water cutters which can turn 90° in the middle of a sheet but also work for devices that only cut the full length of a sheet, there's a user option that changes the software's behavior depending on the cutting device.

[I see David snuck in a posted before I did!]

FWIW, I tried a few and am also currently pretty happy using MacCut V2.

These sound interesting!

I have developed my own manual method for my high end package pricing glass and mat cutting as follows:
1/9, 1/6, 1/4, 1/3, 1/2, 2/3 and full sheet of 32 x 40. and price based on the size I am cutting from.

Basically, I have two sheets; one I have that I cut in half [for 1/2's and 1/4's] and a second that I cut in 1/3's [for 1/9, 1/6, and 2/3]. For glass I cheat and also a box of 18 x 24.

The way mine works is if someone wants an 11 x 14 and I have to cut from a new mat, I will cut a 13" width strip (1/6th) Then the 11 x 14 is cut from the 13 x 14. This works for me, and with the mix I have, I have charged for all my material, and I generally have little waste.

For 10 x 12 [my smallest size] I also cut a 13" wide strip, unless I am doing in quantity.

Thanks, Snafu! I learned about that website yesterday, the day before I saw your post. It looks to be a great solution!
