Hi We had 3 axis CNC(840D PL-NCU 573.4) and we added the fourth axis to it (A axis) and it works correctly. When running the NC programs that machining the arc going from one arc to another the axisfeed override change from 500 to 25(The attached NC program) If we want it to be be fixed feed override what should we do? Thanks. AttachmentNC_Arc.zip (44 Downloads) |

Hi Thanks CHRIS2424242. I modify the NC program according to attached file. I fix the speed to 500mm/rpm in the whole NC program but no change was made.When i change feedrate control in MCP as machining , it doesn't have any influence on the speed. It's noticeable that this acts for G codes that are generated By Software(e.g:CATIA,AUTOCAD,... ) for example the speed is fix on 1000mm/rpm for following NC program from block N10 to N20. N10 G1 X10 Y30 Z-20 F1000 N20 G1 X520 Y-390 Z-400 N30 M30 why controller can't fix the speed? Thanks.
