Saves your material, work and time when you need to cut linear material such as beams, pipes, tubes, profiles or bars. Since implementation users are well satisfied with the system functionalities. In fact Zamil Steel management is considering implementing in other divisions Structure Steel on later stage.
This software has many advantages and by using this application, wastage has reduced. Beside built-in features, TMachines added on request additional functionality as was asked to do so. Zamil Steel is committed to use this software and also expecting future enhancement which can benefit not only to Zamil Steel but other users in the world. As a former student of linear programming, I knew there was a better way.
But, Cutlogic has exceeded my expectations. Our scrap is routinely about half what it was. And the superior results are being achieved in far less time, thus freeing up our staff to do more productive things than trial and error optimization.
In our previous nesting software, we had to hand key all the data into the program. With CutLogic 1D, I can import and optimize all the data for multiple projects with the touch of one button. The operator simply has to review and print the report. This will save us countless hours and key-stroke errors. With the continually rising cost of steel every inch of scrap means lost revenue. Cutlogic has helped to minimize this. The programs are very easy to use and have great functionality.
Cut lists and parts labels can be printed which allows our shop to keep better track of production. Finally, the support received is excellent and new, helpful features have been implemented over the past few years. We would highly recommend this program to anyone who needs accurate cutting plans in 1D or 2D. CutLogic 1D appeared to be virtually tailor made for our purpose and has proved to be very cost effective, easy to use and has paid for itself in the first months of use.
We do not know how we ever managed without it. TMachines listen to their customers and we have found them to be more than helpful and keen to implement changes to improve their product further.Powerful nesting algorithms deliver substantial savings in seconds and the program also generates pick lists.
Use for metal, wood, glass, marble, plastics and 'like' products for maximize yield. Handles multiple stock sizes and parts consolidation.
Optimize on material or handling. Covers sheared and sawn processing with kerf width allowance for saw blade. The essential feature of such a machine is that it does not cut re-entrant corners; it cuts completely through a workpiece at every operation, and every offcut is itself a rectangle.
Machines having such features are common in light metal fabrication, joinery using saws, glass cutting and many other applications. Other machines may be simulated, however, the nesting technique is unchanged. The program begins with entering the list of required widths and lengths.
The Fastest Solver
It will then process the part variations within sheets. It can, in fact, test a whole range of processes over a different range of sheets and the operator can see the sheet layout on the screen. Nesting can be terminated after a specified time has elapsed, or after attaining a specified scrap factor scrap mass expressed as a percentage of total mass of parts.
Nesting can also be interrupted at any time for review of results to date. The program will break down the amount of material into that being used, that which needs to be returned to stock, and that which is scrap. Stock consumption can be prioritized by nominating some items as pre-existing remnant, which forces the use of non-remnant stock where possible.
Alternatively, all offcut can be defined as scrap. Works with Coil as well as Sheet and Bar! Choices for stockfeed are: 1. Lengths as given, 2. Coil cut to mixed lengths, 3.
Coil cut to same lengths. Optimizes Remnant before using Standard size Stocks. Job costing calculator produces material cost and return to stock. Produces simple reports for analysis. Simple job and quote tracking data. DXF Output. Kerf Width Allowance: For a shear, guillotine, cropper etc. Other thermal or mechanical cutting processes usually result in a finite loss of material which can be specified as Kerf Width Allowance. Fastcut takes the guesswork out of determining how much material we need, and how to cut each panel for maximum utilisation of the material.
All our locations have responded very positively and all were up and running witn hours of installation. Affects your bottom line in such an easy, instant and dramatic way! There's not a lot of software in this price range that affects your bottom line in such an easy, instant and dramatic way.
It gives the operator the complete graphics of the cutting required on a particular job. And as the program allows for dates of jobs and materials used, it can also be used as a very simple and basic quoting system.Breakthrough new capabilities in Gurobi Optimizer, plus major new features for Gurobi Compute Server.

The workflow is pretty simple: create project, define material to cut and enter or import lengths to cut. You can use it not only to optimize your cutting lists but also to organize your data into projects, have track of your materials and print optimization results suitable for your workshop. The cut optimizer is fully online solution. No need to install anything on your machine. All you need is internet browser. We do all processing on our servers, so you can use it on all devices, including mobile phones and tablets.
We also prepared paid plans, that give you more power. With the paid plans you can cut more items, cut more materials in the same project, have more projects and predefined materials. You can also immediately get the total cost of the material and there is more to come. You can see the details about the paid plans here:. All premium plans are offered with 7-days trial that is free. So, feel free to give it a try and see if it suits you well.
Also, even though we have paid plans now, the original idea of the free cut optimization is still there. Basic free plan supports everything the old application did, even without creating account on the website. But, unlike the MS Excel app, the algorithm is much faster and gives better results.
Follow Us.Linear optimization or linear programming is the name given to computing the best solution to a problem modeled as a set of linear relationships. These problems arise in many scientific and engineering disciplines. The word "programming" is a bit of a misnomer, similar to how "computer" once meant "a person who computes. For a good primer on linear optimization, we recommend the Mosek modeling cookbook.

The Linear Optimization Service in Google Apps Script lets developers make function calls to solve linear optimization problems. It relies on Glop for pure linear-optimization problems where all variables can take on real values.
Only the first option requires installing OR-Tools.Our free online cutlist optimizer can be used to work out the best way to cut your lengths of material to get the most efficient cuts from the material and save wastage.
The calculator can be used for any linear material whether it be steel, metal, wood timberplastics, etc. In the "Settings" box, enter the length of the steel or wood that you will be cutting the required lengths from.
Your measurements can be in inches, feet, cm centimetresmm millimetres or metres. A lot of steel is not exactly the length that it is sold as. For example an 8 metre length of steel that is sold as 8 metres, may be 10 or more millimetres longer than 8 metres. Therefore, if you enter that you need 1 x mm and 1 x mm, then with a kerf of 1.
In the "Settings" box, enter the kerf. The kerf is the width of the cut and will vary depending on the width of the band saw blade or cutting disc that are using.
In the "Cuts" box, enter the length and number of required pieces of steel that are needed for your project and click the "Add" button after each one. If you need to remove any cuts from the list, simply click on that particular entry and it will be removed. Click the "Print Visual Cutting List" button if you wish to print the sheet showing the layout.
Click the "Print List" button if you would like to print the list of cuts that you have entered. NOTE: If your measurements are in fractions of an imperial inch, these will need to be converted from fractions to decimals.
A table of fractions of an inch to decimals and millimetres can be found here opens in new window : Convert Imperial Fractions to Decimal and Millimetres. A short video showing our cutting list calculator in action can viewed here opens in new window : Linear Cutting List Calculator Intro Video.

How to use the Kurraglen Industries cutting optimiser 1. In the "Stock" box enter any stock that you already have cut.
We have an updated version of our Linear Cutting List Calculator. The cuts you want to make. Any stock you have on hand.Bear in mind that -- since the Assume Linear Model box is unchecked by default -- the Solver will try to solve your model using the GRG method, even if it is actually a linear model that could be solved by the faster and more reliable Simplex method.
The GRG method, while it is always slower, will usually find the optimal solution to a linear problem -- but occasionally you will receive a Solver Completion Message indicating some uncertainty about the status of the solution -- especially if the model is poorly scaled, as discussed above.
So you should make sure that the Assume Linear Model box is checked for linear problems. A nonlinear problem may have more than one feasible regionor set of similar values for the decision variables, where all of the constraints are satisfied. Within each feasible region, there may be more than one "peak" if maximizing or "valley" if minimizing -- and there is no general way to determine which peak is tallest, or which valley is deepest. There may also be false peaks or valleys known as "saddle points.
When dealing with a nonlinear problem, it is a good idea to run the Solver starting from several different sets of initial values for the decision variables. Since the Solver follows a path from the starting values guided by the direction and curvature of the objective function and constraints to the final solution values, it will normally stop at a peak or valley closest to the starting values you supply.
By starting from more than one point -- ideally chosen based on your own knowledge of the problem -- you can increase the chances that you have found the best possible "optimal solution. Frontline's Premium Solver Platform can automate the process of starting the Solver from different initial values, using so-called multistart methods for global optimization.
You may also wish to consult our Solver Tutorial and the Premium Solver Platform User Guide for further information about "locally optimal" and "globally optimal" solutions. At best, the GRG Solver -- like virtually all nonlinear optimization algorithms -- will find a locally optimal solution to a reasonably well-scaled model.
At times, however, the Solver will stop before finding a locally optimal solution, when it is making very slow progress the objective function is changing very little from one trial solution to another or for other reasons.

Nonlinear problems are intrinsically more difficult to solve than linear problems, and there are fewer guarantees about what the Solver or any optimization method can do.
The Solver uses the GRG Generalized Reduced Gradient algorithm -- one of the most robust nonlinear programming methods -- to solve problems whenever the Assume Linear Model box in the Solver Options dialog is unchecked.
When the box is checked, the Solver uses the Simplex method for linear programming problems. Feasible Regions, Peaks and Valleys A nonlinear problem may have more than one feasible regionor set of similar values for the decision variables, where all of the constraints are satisfied.
Slow Progress and Stopping Conditions At best, the GRG Solver -- like virtually all nonlinear optimization algorithms -- will find a locally optimal solution to a reasonably well-scaled model.
