G332 X… Y… Z… I… J… K…● SPOS (or M70) only has to be programmed prior to tapping:– For threads requiring multiple machining operations for their production– For production processes requiring a defined thread starting positionConversely, when machining multiple threads one after the other, SPOS (or M70) does nothave to be programmed (advantage: Saves time).● The spindle speed has to be in a dedicated G331 block without axis motion before tapping(G331 X… Y… Z… I… J… K…).MeaningG331: Command: TappingThe hole is defined by the drilling depth and the thread lead.Effective: ModalG332: Command: Tapping retractionThis movement is described with the same lead as the G331 movement. Thedirection of rotation of the spindle is reversed automatically.Effective: ModalX... Y... Z... : Drilling depth (end point of the thread in Cartesian coordinates)I... : Thread lead in X directionJ... : Thread lead in Y directionK... : Thread lead in Z directionValue range of lead: ±0.001 to 2000.00 mm/revNoteAfter G332 (retraction), the next thread can be tapped with G331.NoteSecond gear-stage data blockTo achieve effective adaptation of spindle speed and motor torque and be able to acceleratefaster, a second gear-stage data block for two further configurable switching thresholds(maximum speed and minimum speed) can be preset in axis-specific machine data deviatingfrom the first gear step data block and also independent of these speed switching thresholds.Please see the machine manufacturer’s specifications for further details.References:Function Manual, Basic Functions; Spindles (S1), Section: "Configurable gear adaptations".Motion commands10.11 TappingFundamentalsProgramming Manual, 01/2015, 6FC5398-1BP40-5BA2 235 |
