Tebis holds seminar with expert partners to demonstrate convincing manufacturing results
Users can achieve first-class manufacturing results if the machine, software and tool are optimally harmonized. This was demonstrated to more than 60 visitors at the Die & Mold Days exhibition, which took place early in the summer at the GROB technology and application center in Mindelheim, Germany. Also present were technology partners MMC Hitachi Tool and Tebis, a process supplier for the development, design and manufacturing of models, molds and dies and components.
The highlight of the two-day exhibition was the live manufacturing of a workpiece. This workpiece was programmed specifically for the seminar using Tebis Software. It included typical machining types for die and mold manufacturing, ranging from prismatic machining (2.5D) to deep-hole drilling to free-form machining to the production of ribs. The latest tool developments from MMC Hitachi Tool were implemented on two different 5-axis machining centers from GROB.
During the presentation section, the expert partners explained why the part could be so efficiently machined with this combination of machine, manufacturing solution and tool technology. GROB explained the benefits of the G350 and G550 machining centers and MMC Hitachi Tool presented the "Production 50" manufacturing concept. This concept uses highly sophisticated and adapted tools in combination with new manufacturing strategies. The solution also enables users to reduce their costs by up to 50%.
Combined roughing and finishing strategies in 52 HRC
The workpiece was so well prepared with Tebis software and the manufacturing knowledge stored in the process libraries that it could be machined automatically in both the soft and hardened state. The software has roughing strategies that are suitable for use of both high feed-rate cutters and high-performance cutters. The process libraries model the customer's manufacturing knowledge. For example, the libraries include tool data with the manufacturer's optimized parameters. That way, the data can be used repeatedly and reliably. This results in perfect cutting conditions for not only the tool but also for the subsequent process. This is based on realistic modeling of the cutting geometries during NC path calculation.
Visitors were especially interested in the demanding machining operations in 52 HRC. The cooperative effort of the three technology partners enabled the demonstration of a new approach for residual stock roughing at the seminar. This approach combines roughing parameters and finishing strategies in Tebis.
