CAM, he said. “Those same features, diameters, hole depths, etc., can be automatically read by the CAM system, instilling confi dence in the user regarding programming and automation,” Sivitter said. Automating the know-how of frequently performed
operations is key for many manufacturing processes, particularly for machining operations such as pocket-
contrast, DP Technology is using a “cloud-enabled” CAM connection with Esprit, keeping the software as a stand-alone CAM system while offering links with the Machining Cloud (Stans, Switzerland), a provider of cloud-based machining system and tooling database information. “At DP Technology, we understand and value the cloud trend. Still we are also aware of its limits and risks with respect to the CAM industry,” said DP Technology’s Simard. “We have decided to keep Esprit as a stand-alone CAM application for it to be as close to the machine tool as possible, or in other words, completely integrated in shop fl oor and the machinist’s physi- cal environment.” With the Machining Cloud,

ing on large aircraft structural components, noted Jean-Marc Cauzac, Delmia Manufacturing Consultant, senior machining expert, Dassault Systèmes (Paris). Reusing this captured knowledge is impor- tant. “Especially for manufacturers working on one domain, like aerospace, this is key because you’re working on the same kind of parts. CATIA V6 includes a lot of knowledgeware inside,” Cauzac added. “You want to reuse the same parameters because you know it’s working.”
CAM in the Cloud New cloud-based systems also are another positive
development in CAM, Cauzac said. “The cloud solu- tion is very good. With the cloud, I think we’re at the beginning. When you take a look to your daily activity, everything is done through the Internet. This allows you to manage the supply chain through the cloud.” Notable developments in cloud-based CAM
include Autodesk’s CAM 360 announced last year. In SS14

Esprit programmers have access to complete and up- to-date tooling product data, cutting hours of programming time by eliminating manual tool creation, Simard added. “Cloud-enabled Esprit simpli- fi es the selection of cutting tools. It offers a list of recom-
mended cutting tools based on machining features and machining sequences, and simulates with accu- rate 3D models of tool components and assemblies.”
Adding Additive With the growing interest in additive manufac-
turing, CAD/CAM developers are also looking into programming alternatives for innovative new hybrid additive-subtractive machining systems coming onto the market. But most see this as a complementary technology to traditional subtractive manufacturing techniques and software, given the current limitations of AM on part precision and for manufacturing in large volumes. “An additive toolpath is not a CAM toolpath in
reverse,” said Frankel of Siemens PLM Software. “We are working with DMG Mori to develop research and development on this. It’s research at this point in time.” Manufacturing processes have evolved in many ways over many years, said Vero’s Sivitter, noting that
