The first part would be programmed over several weeks with no time pressure and optimized to the maximum extent possible. Both software providers were tasked with programming identical workpieces. It ultimately came down to a showdown between the two CAD/CAM systems. Other companies queried by the Riemann team also shared this opinion.
On the other, the managing directors and the programming team had always regarded Tebis as a high-end solution. On one hand, Tebis was already being used by most of Riemann's customers. But we’re not always satisfied with taking the easiest route, especially when better alternatives are available. "The easiest for us would have been to update the existing system. "We had to take action," Riemann says, describing the situation at the time. In addition, the system we were using didn’t support templates, like those used for recurring programming tasks. More complex calculations often ran all night. The ratio of programming time to spindle run time was no longer cost-effective. This was already apparent when we wanted to rotate a piece by 180° on the display: The designer might as well take a long coffee break.” "Aside from the fact that the system was deficient in some areas, calculation times were also getting longer due to the highly complex geometries and the larger milling volume. "Whereas in the past we had orders with 200 to 300 h of milling, today we have orders with 5,000, 6,000, even up to 10,000 h of milling," Riemann explains. The growing complexity of the workpieces being machined, and the ever-increasing milling volume required in recent years made us painfully aware of the limitations of the CAD/CAM system that was previously in wide use. Now we can't manage without 5-axis machines because of the increasingly demanding geometries.”
"Just a few years ago, 80 percent of our manufacturing was on 3-axis machines. "There’s a very clear trend toward 5-axis machining," says Michael Riemann, who heads the company along with his brother Peter and his father Klaus Riemann.
