Fabrizio Resmini, Bruce Williams, Dr. Wolfgang Sengebusch, and Makoto Takeuchi participate in the conference. Global opportunities were on the agenda of the third World Conference for Manufacturers of Metal-Cutting Tools. According to Program Chairman Gary Vanderpol of Criterion Machine Works Inc., Costa Mesa, Calif., the event let members of the United States Cutting Tool Institute (USCTI), the European Cutting Tool Association (ECTA), and the Japan Cutting Tool Association form alliances, network, and carry on business relationships with industries from all corners of the globe. Conference-goers wanted to let end users know, We are working together as diligently as possible as a world industry to bring customers the best-possible products. Because of the global economy, one of the top concerns facing this industry centered on collaboration. Conference participants indicated that despite competitiveness, collaboration between associations,
U.K.-based Ferroday Ltd. gave a presentation on ISO 13399, a new standard that describes modern cutting tools. And technology such as CAD, CAM, and PDM systems, as well as advancements in production simulation, tool presetting, and enterprise resource planning, mean a greater role for computer systems in cutting tool selection. Modern tools can also have multiple functions based on the demands of multitasking machines. This means new standards containing more information are required to explain the capabilities of products controlled by computer systems. Shared collaboration and economic issues did not damper anyones enthusiasm to see new products in action. Dr. Dirk Friedrich, from Germanys WZL Laboratory for Machine Tools and Production Engineering at the University of Technology, Aachen, gave a presentation on Conference-goers learn about global business concerns.
experimental cutting tool geometries that addressed the paradox inherent in grinding carbide inserts with grinding wheels. Dr. Friedrich explained, In a grinding process, you want the grit to win, while in a cutting process you want the insert to win. This leads to questions as to how to best make an insert or a cutting tool with the most efficient processes. Friedrich commented that opportunities abound in virtual machining, which allows simulated trials with tool geometries so crazy no one could believe they would remove anything. Simulated trials let companies closely analyze chip creation, including the surfaces behind chips. Thats because virtual reality can be stopped mid-process, not possible on a real machine. As Friedrich said, You can examine your insert and see how it behaves from temperature extremes to high stresses. And you can see the stresses of the chip on your workpiece. While wear of geometries can never be totally avoided, new geometries are minimizing crater wear. Participants also discussed recent developments in HSS coated with powdered metal. Williams commented, The development work in powdered-metal technology will allow an extension of HSS use. It will be interesting to see how effective this is because powdered metal is currently expensive. But this technology allows higher high-end hardness, and the tool is less brittle. Also, these tools dont require quite as rigid a machine, so they work on older equipment. And there is still a lot of production that takes place on older equipment with four spindles. Resmini agreed, adding, Newer equipment lets you benefit from carbide inserts. But we have a huge market of medium-sized companies that are not into big-batch production. Theyre more concerned with tool life than cutting performance. In this case, well-coated HSS can compete with carbide.
