Okuma Alarm-B 2514 MULTI CYCLE C-axis shift
Droop check timer(parameter) in has passed with C-axis position shifted more than the width of Droop(parameter) when starting at the hole processing fixed cycle.
Droop:USER PARAMETER -> DROOP DATA
Droop check timer:OPTIONAL PARAMETER(MULTIPLE MACHINING) -> Droop check timer in hole processing
Probable Faulty Locations
1) command value(CON) and actual position(APA) shifted by the processing before.
2) hole processing fixed cycle started before actual position(APA) reached Command value(CON).
Measures to Take
1) C-axis is unclamped (M146), and the position of C-axis is mended.
It corrects it to the program to which position (CON) in which it instructs in C-axis and present location (APA) do not shift.
2) A set value of Droop check timer of an OPTIONAL PARAMETER(MULTIPLE MACHINING) at the hole processing fixed cycle is reviewed.
