Progressive Die Design – Progressive Die Design is a new product being introduced in CimatronE Version 8. Cimatron is currently one of the few CAM software vendors to offer such a capability. Progressive dies are commonly employed to produce sheet metal components in industries such as automotive, consumer products, computers, and electronics. A progressive die sequentially transforms a flat strip of metal into a completed part by employing a series of stations that cut, form and coin the material into the desired shape. In Progressive Die Design a user analyzes the part, builds the strip layout, creates the die tool and documents the process.

It includes a combination of automation and hands-on control to offer speed, consistency, flexibility and the ability toreduce the trial-and-error iterations. It is intelligent, parametric, and associative.

Software is provided for finite element analysis, strip design, die set design, detailed tool design, tool validation, machining and support of shop floor operations. The system allows users to work in the method they prefer and an ‘Intelligent Toolbox’ makes the relevant tools available for each task at the appropriate time. Integral finite element analysis is used for the standard blank calculation and thinning analysis as well as in surfacing operations which are used for unbending, unfolding and compensation for spring back. Cimatron offers a hybrid solid and surface-based system. A rich surfacing package is provided

This capability, which is especially apparent during nesting and strip design, enables users accustomed to working in a 2D environment, to continue to do so while also enjoying the benefit of 3D robustness. Users can also start designing directly in 3D.

Mr. Jay Weiner, IT Manager at CAM Tool & Die Ltd. stated, “The new Cimatron Progressive Die product is very flexible and powerful. By starting in 3D we expect substantial productivity improvements. The surfacing package is second to none. There are no limitations on what can be done.” 2 T: h4 A! o' e2 d; q8 `) _6 h3 @

Support for Large and Complex Molds – Cimatron is able to effectively support the design of large and complex molds. In Version 8, the increase in capacity and performance ranges from 35% to 50%. As one specific example, aleading automotive provider utilized CimatronE to create a bumper mold that was 3.2 meters long, had 1,200 parts, and 36,000 faces. (see Figure 2 below) M* [, g3 A' h. y

In addition, quick-modification tools allow users to make immediate local changes. With these tools the system can perform any complex change within seconds, even in a mature assembly, holding thousands of components.

An additional new feature, particularly useful for large mold shops, is concurrent mold design. This feature allows several users to simultaneously work on the same mold assembly, with each portion of the mold owned by a different user. ) k2 m/ @# T* E/ B
