ModuleWorks has successfully tested its latest calculation strategies for rotary and geodesic machining using a barrel mill finishing tool. The trial was conducted at the Hommel and Okuma Technology Center in Langenau, Germany, on an Okuma Multus-B200W multitasking CNC machine. The selected workpiece was a spiral mandrel distributor, which presented a realistic challenge for multi-axis milling algorithms.

The trial focused on testing barrel mill machining strategies for pre-finishing the walls of workpieces. According to the company, the barrel shape of the selected finishing tool generated small cusps and delivered a quality surface finish. It used large stepovers that accelerated the machining process. A taper barrel tool further improved performance by using the large barrel section to machine the workpiece walls and the tool tip to machine the inner corners. Read more.

  • How to Slash 5-Axis Finishing Time

    Finally there is an alternative to ballnose endmills for finishing 3D parts. The combination of finishing tools shaped to provide more cutting surface and a CAM system with the ability to apply them on a five-axis machining center can dramatically reduce finishing cycle times while delivering better surface finishes.
