10.2.6 Multi-edge (CYCLE79)FunctionYou can mill a multi-edge with any number of edges with the "Multi-edge" cycle.You can select from the following shapes with or without a corner radius or chamfer:NoteUsing side mills and sawsWhen using a side mill (type 150) or a saw (type 151), the first infeed is selected so that thetop edge of the tool touches reference point Z0 exactly. At the end of the machining, the toolis extracted completely from the blank spigot. In this way, an inner multi-edge can be produced.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/retraction1. The tool approaches the starting point at rapid traverse at the height of the retraction planeand is fed in to the safety clearance.2. The tool traverses the multi-edge in a quadrant at machining feedrate. The tool firstexecutes infeed at machining depth and then moves in the plane. The multi-edge ismachined depending on the programmed machining direction (up-cut/down-cut) in aclockwise or counterclockwise direction.3. When the first plane has been machined, the tool retracts from the contour in a quadrantand then infeed to the next machining depth is performed.Programming technological functions (cycles)10.2 MillingMillingOperating Manual, 08/2018, 6FC5398-7CP41-0BA0 445
