(Ok here I am mumbling into a microphone before the crowd... ) But going way, way, way back ( Picture in your minds eye teletypes and paper tape programs...) I had always wanted a ramped feed rate command. Like G1 X1. Z-.25 F20. ( ramp command) X4. Z-1. F5. So that the move from X1. Z-.25 to X4. Z-1. would start at F20. and slow to F5. by completion of the move. This could be a one shot ( like a G04 ) or modal, or both. Another use would be for a part off lathe tool being fed in FeedPerMin vrs FeedPerRevolution. Same could apply to feeding a tapered ream, start at F.02 end at F.002 ( FPR ) Often there are other easy ways to do things, but sometimes it would be the best method - were it available. Just thinking outloud Greg
