● Finishing● Base finishing● Edge finishing● ChamferingVortex millingParticularly where hardened materials are concerned, this process is used for roughing andcontour machining using coated VHM milling cutters.Vortex milling is the preferred technique for HSC roughing, as it ensures that the tool is nevercompletely inserted. This means that the set overlap is precisely maintained.Plunge cuttingPlunge cutting is the preferred method of machining slots for "unstable" machines andworkpiece geometries. This method generally only exerts forces along the tool axis, i.e.perpendicular to the surface of the pocket/slot to be machined (with the XY plane in Z direction).Therefore, the tool is subject to virtually no deformation. As a result of the axial loading of thetool, there is hardly any danger of vibration occurring for unstable workpieces.The cutting depth can be considerably increased. The plunge cutter, as it is known, ensuresa longer service life due to less vibration for long overhangs.Input simpleFor simple machining operations, you have the option to reduce the wide variety of parametersto the most important parameters using the "Input" selection field. In this "Input simple" mode,the hidden parameters are allocated a fixed value that cannot be adjusted.Machine manufacturerVarious defined values can be pre-assigned using setting data.Please refer to the machine manufacturer's specifications.If the workpiece programming requires it, you can display and change all of the parametersusing "Input complete".Approach/retraction for vortex milling1. The tool approaches the starting point in front of the slot in rapid traverse and maintainsthe safety clearance.2. The tool goes to the cutting depth.3. The open slot is always machined along its entire length using the selected machiningmethod.4. The tool retracts to the safety clearance in rapid traverse.Programming technology functions (cycles)10.4 MillingTurning482 Operating Manual, 05/2017, A5E40868721
