Programming a cycle4.7 MillingHMI sl Turning246 Operating Manual, 01/2008, 6FC5398-7AP10-0BA0ParametersParameter Description UnitPL Machining plane: 1)G17 (XY)RP Retraction plane (abs)Normally, reference point Z0 and retraction plane RP have different values. Thecycle assumes that the retraction plane is in front of the reference point.SC Safety clearance (inc)Acts in relation to the reference point. The direction in which the safety clearanceis active is automatically determined by the cycle.F Feedrate mm/minFZ Depth infeed rate mm/minMachiningposition• Single positionAn elongated hole is machined at the programmed position (X0, Y0, Z0).• Position patternSeveral elongated holes are machined in the programmed position pattern(e.g. pitch circle, grid, line).X0Y0Z0The positions refer to the reference point:Reference point X – (for single position only)Reference point Y – (for single position only)Reference point ZmmmmmmL Elongated hole length mmα0 Angle of rotationZ1 Elongated hole depth (abs) or depth in relation to Z0 (inc) mmDZ Maximum depth infeed mmInsertion The following insertion modes can be selected:• Centered: Insert vertically in longitudinal groove center:The tool is inserted to infeed depth in the pocket center.Note: This setting can be used only if the cutter can cut across center.• Oscillation: Insert with oscillation along center axis of longitudinal groove:The cutter center point oscillates along a linear path until it reaches the depthinfeed. When the depth has been reached, the path is traversed again withoutdepth infeed in order to remove the slope caused by insertion.mm1) Parameter description refers to plane G17; plane selection G18 or G19 possible in selection field(MD 52005: $MCS_DISP_PLANE_MILL)!
