Services FAQ's

  1. Can you predict springback in Aluminium using a 2D cross section?
  2. If it is determined by one of your clients that a tool design provided needs a little "tweaking", what kind of technical support, if any, will be provided after the initial CAD files have been delivered to help tweak the design?
  3. I want to get a job simulated but I need my boss to authorize the expenditure. How can I convince my boss that forming simulation is worthwhile?
  4. We usually etch a grid of circles into our blank then form it and analyze the amount of stretch in two directions by measuring how much each circle deformed. Can the simulation software do the same thing?
  5. I think my part needs to be formed in more than one stage, because it is a very deep draw and complicated shape. Can you simulate a two stage draw?
  6. We usually cut cross sections and check for undercut in a forming tooling in 2D. Do you have a better way to check for undercut?
  7. We usually design our own die faces. Can you simulate one of our existing designs?
  8. How long does it take StampingSimulation.com to provide simulation results?
  9. After perfecting a tool design using virtual tryout, can StampingSimulation.com provide the die face data used in the simulation?
  10. Can StampingSimlation.com really read ANY CAD format I upload? What format do you prefer?

Q. What is finite element analysis? What's the difference between this and forming simulation?

A. Finite element analysis simply uses the fundamental laws of physics to calculate the behavior of a material at a set number (finite) number of points. The more points (elements) used in the calculation, the more accuracte the result, but the longer the calculation takes. Forming simulation is not different to finite element analysis, but rather a specific application of the method.

Q. How accurate is EasyBlank? What if the blank needs to be developed through multiple stages?

A. EasyBlank assumes the part is formed entirely in a single stage from a 100% developed blank. If this is not the same process that will be tooled, the blank needs to be developed virtually through each forming stage for an accurate result. However, in all cases, EasyBlank gives a quick and approximate blank shape which can be used for quotation and initial blank shape purposes.

Q. Am I able to use the results I buy from EasyBlank for commercial purposes?

A. Yes. By purchasing the results you have generated from EasyBlank, you have obtained the right to use the data for commerical purposes. For full details, see the complete ORDER TERMS statement, which can be found by navigating the HELP menu within the EasyBlank application.

Q. Can you send me a demo version or trial version of AutoForm so I can have a go at doing simulations myself?

A. This site is for those people who do not want to buy or do not have the time to spend on simulation software. If you are interested in purchasing Autoform, then please visit our page on AutoForm's products.

Q. How much does forming simulation software cost? Can't I just buy the software myself and use it without StampingSimlation.com?

A.

The upfront purchase cost of forming simulation software ranges from $20,000 to $100,000+ and training for such also costs around $1,000 per day with a typical need for 5 days training to become competent in the software. Often, repeat and additional follow up training is also required after the initial training of such software. Also, suitable PC hardware is required to run the software (add $5,000) and usually a dedicated specialist engineer is required to run the software and report the results. Whilst this is considerably cheaper than what the same technology cost 5 years ago, StampingSimlation.com can provide all this to your business for a fraction of the cost, on a consulting basis.

Q. Can you predict springback in Aluminium using a 2D cross section?

A. Yes. At first the 2D cross section would be extruded into 3D (forming simulations are best done in 3D) to some arbitary length. Next a forming simulation of the part would be conducted to induce strains and stresses as would be the case in a real forming process. Lastly, a springback analysis is performed and the amount of springback can be seen in cross section or in 3D. Springback can be predicted in any material.

Q. If it is determined by one of your clients that a tool design provided needs a little "tweaking", what kind of technical support, if any, will be provided after the initial CAD files have been delivered to help tweak the design?

A. StampingSimulation.com provides more than just a simulation service. Because of the experience and knowledge StampingSimulation.com has with sheet metal tooling, development work such as revising die face designs, is always included in the quoted price. When problems are found, the service does not stop. The aim of StampingSimulation.com is to SOLVE YOUR PROBLEM, not just show you the problem. Of course, the customer's ideas can be simulated too. The idea is to simulate as many ideas and countermeasures as possible in the virtual environment before committing to costly tooling manufacture. A small amount spent upfront in simulation will save thousands in the later stage of a tooling project.

Q. I want to get a job simulated but I need my boss to authorize the expenditure. How can I convince my boss that forming simulation is worthwhile?

A. Try using the EasyBlank tool. It is free to download.

Q. We usually etch a grid of circles into our blank then form it and analyze the amount of stretch in two directions by measuring how much each circle deformed. Can the simulation software do the same thing?

A. Yes. If requested, the results produced can include a virtual circle grid plot so you can see the strains just like you are used to doing. Furthermore, you can compare the virtual results with the real results by checking the deformation of the circles on your actual part.Each circle was plotted on the blank BEFORE forming as a perfectly round circle. AFTER forming, the amount of deformation and the direction of deformation can be seen by inspecting each circle. Measurements can also be taken to determine the amounts of strain. This is a common method used by many toolmakers to help solve forming problems. Now, it can be done virtually without the need to build a tool. Contact us if you would like to know more.

Q. I think my part needs to be formed in more than one stage, because it is a very deep draw and complicated shape. Can you simulate a two stage draw?

A. Yes. A pre-draw can be simulated and then the results from the pre-draw can be fed into a final stage form and the sum total of strains measured and displayed, to show areas of splits or wrinkles. Actually, as many stages as required can be simulated.

Q. We usually cut cross sections and check for undercut in a forming tooling in 2D. Do you have a better way to check for undercut?

A. Yes. StampingSimulation.com can provide a full 3D undercut check and then give you the CAD that has been tipped into the most suitable pressing direction. If there is any undercut we will show you where it is and what could be done to fix the problem.

Q. We usually design our own die faces. Can you simulate one of our existing designs?

A. Yes. Use our SimulateLite service.

Q. How long does it take StampingSimulation.com to provide simulation results?

A. When submitting a quotation request, it is helpful if you can tell us the timeframe you are working to. This will help us ensure we meet your expectations. Initial results for most jobs are usually turned around in under 24 hours. For customers participating in promotional offers - we will always prioritize regular clients, however you can normally expect results within 1~2 days.

Q. After perfecting a tool design using virtual tryout, can StampingSimulation.com provide the die face data used in the simulation?

A. Yes, once die face surfaces have been proven virtually using simulation, the surfaces can be provided as ".igs" for use in an actual tool build.

Q. Can StampingSimlation.com really read ANY CAD format I upload? What format do you prefer?

A. We can read just about any CAD format you upload. However, should we receive an uncommon format or format that is difficult to translate, it will affect the time taken to provide the simulation service. To ensure the service can be provided as quickly as possible, we prefer ".igs" format because just about every CAD package can read and write this format.
