“Advanced machine simulation can both avoid these collisions, plus reduce machine time by allowing the user to optimize the toolpath.” In aerospace machining, highly accurate machine simulations are mandatory. With the Dassault Sys- tèmes V6R2014 suite of CAD/CAM applications, aero- space users can now take advantage of full machine simulations before taking product designs to the shop fl oor, said Jean-Marc Cauzac, Delmia Manufacturing Consultant, senior machining expert, Dassault Sys- tèmes (Paris), and it’s important for software develop- ers to work with customers in tight process integration on designs both upstream and downstream before going to the factory fl oor.
“In the aerospace domain, one of the biggest requests is from customers machining structural parts with a lot of pockets. People are machining pocket by pocket, and machining that manually. But today we are delivering an operation that is able to do that au- tomatically,” Cauzac said. With Delmia’s V6 Machine Builder and related applications, users can accu-

rately visualize aerospace bulkheads, wings or other structural components as well as all the machine tool elements prior to cutting components. Multitasking and Swiss-style machines continue to
be very popular and are available with increasingly dynamic confi gurations, said Dave Bartholomew, product manager, DP Technology Corp. (Camarillo, CA), developer of Esprit CAM software. “More than ever before, we’re seeing an increase in the complex- ity of machined parts, more advanced and complex machine tools, and heightened complexity in NC programming,” Bartholomew said. “As a means of contending with the increasing complexity, CNC pro- grammers are looking for a complete programming solution—one that is easy and intuitive to use, takes full advantage of the capabilities of their machine tools, and produces accurate NC code.” Ensuring a complete solution means providing a realistic representation of the machine tool for simu- lation and verifi cation, including the ability to see all axes’ movements and, in cases of potential violations,
