If the workpiece programming requires it, you can display and change all of the parametersusing "Input complete".Approach/retraction1. The tool approaches the center point of the semicircle at the end of the slot at rapid traverseat the height of the retraction plane and adjusts to the safety clearance.2. Then, the tool enters the workpiece at machining infeed (taking into consideration themaximum infeed in the Z direction and the finishing allowance). The circumferential slot ismachined in the programmed machining direction (up-cut or down-cut) in a clockwise orcounterclockwise direction.3. When the first circumferential slot is finished, the tool moves to the retraction plane at rapidtraverse.4. The next circumferential slot is approached along a straight line or circular path and thenmachined.5. The tool moves back to the safety clearance at rapid traverse.Machining typeYou can select the machining mode for milling the circumferential groove as follows:● RoughingDuring roughing, the individual planes of the groove are machined one after the other fromthe center point of the semicircle at the end of the groove until depth Z1 is reached.● FinishingIn "Finishing" mode, the edge is always machined first until depth Z1 is reached. The grooveedge is approached on the quadrant that joins the radius. In the last infeed, the base isfinished from the center point of the semicircle to the end of the groove.Programming technological functions (cycles)10.2 MillingMillingOperating Manual, 05/2017, A5E40868956 405
