ModuleWorks successfully tested its latest calculation strategies for rotary and geodesic machining using a barrel mill tool for accelerated, high quality finishing.

The trial was conducted at the Hommel and Okuma Technology Center in Langenau, Germany on an OKUMA MULTUS-B200W Multitasking CNC machine with MMC Hitachi Tool standard stock items, including barrel mill tools. The selected workpiece was a spiral mandrel distributor that provided a realistic and technically sophisticated challenge for the new multi-axis milling algorithms.

A key focus of the trial was to test the new barrel mill machining strategies for pre-finishing the walls of the workpiece. The barrel shape of the tool generates smaller cusps and delivers a high-quality surface finish while using large step overs that significantly accelerate the machining process. Using a taper barrel tool optimizes performance further because the walls can be machined using the large barrel section of the tool and the inner corners using the tip.

Deburring was performed using the ModuleWorks deburring cycle that automatically creates a toolpath for spherical tip tools along all sharp edges of a workpiece. This saves a lot of time and effort because machine operators no longer need to manually adjust the conventional generic toolpath strategies. Instead, operators select the entire workpiece and the algorithm automatically finds the edges and applies automatic tilting to calculate a collision-free toolpath.

“Multi-axis rotary machining is technically very challenging, and it’s exciting to see how our new toolpath strategies for barrel mill tools significantly enhance both the efficiency and the quality of the machining process”, says David Plater, Technical Director at ModuleWorks.” This trial demonstrates the effectiveness and potential of the technology and provides the foundation for continued improvements and future developments.”
