The Brother control has several unexplained Speed and Feed options, just abbreviations, that I haven't got canonical names for, I'd like to understand exactly what each parameter means, so here goes:
Under Drill and Tap speeds, they reference S and L with different values. For Drills the SFM and IPR varies for S and L, with L typically having double the IPR as S.
In what situation would S be used and L be used? Furthermore, in what machining situation would you double your IPR for a drill vs another drill?
Presumably the S stands for "small" and L for "large", but the ambiguity is bugging me.
Second, with Endmill speeds and feeds, they have 2 values labeled "CRF" and "TRV", one could infer these to be for plunging and milling, since the Brother has no ramped feed, all milling is done as plunging, then feeding.
What is the canonical name for "CRF" and "TRV"?
Any help is appreciated, Thanks.
OBTW, did my first repair on the machine yesterday, one of the tool holder fingers was *bent* and it dropped the tool from that spot twice, the first time it didn't hurt anything since it was a point tap, just put a divot in the table, which was easy to fix, caught it the second time. I dunno how the thing got bent, the arms look to be forged steel, *very* strong and beefy forgings, I straightened it on an arbor press and all is good.
