Parameter Description UnitTR Reference tool Tool, which is used in the "Stock removal" machining step. This is usedto determine the plunge position.Z0 Reference point in the tool axis Z mmZ1 Pocket depth (abs) or depth referred to Z0 (inc) mmDXY ● Maximum plane infeed● Maximum plane infeed as a percentage of the milling cutter diametermm%UXY Finishing allowance, plane mmUZ Finishing allowance, depth mmLift mode Lift mode before new infeedIf the machining operation requires several points of insertion, the retraction height towhich the tool is retracted, is selected as follows:● To retraction plane● Z0 + safety clearanceIf there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" canbe selected as the lift mode.mmmm10.3.10 Milling contour pocket (CYCLE63)FunctionBefore you can machine a pocket with islands, you must enter the contour of the pocket andislands. The first contour you specify is interpreted as the pocket contour and all the others asislands.From the programmed contours and the input screen form for stock removal, the cyclegenerates a program that removes the pockets with islands from inside to outside in parallelto the contour.The islands can also be located partially outside the pocket or overlap each other.NoteExecution from external mediaIf you execute programs from an external drive (e.g. local drive or network drive) then yourequire the execution from external storage function (EES).For additional information, please refer to the following references:SINUMERIK Operate Commissioning ManualProgramming technological functions (cycles)10.3 Contour millingMilling448 Operating Manual, 05/2017, A5E40868956
