00:02:57 good evening 00:04:09 if cutting 1/4" steel plate with coolant on top of the cut, don't assume there's coolant at the bottom of the cut 00:04:32 oops 00:04:42 the fireworks were neat 00:04:45 wow 00:04:56 you must have been using carbide? 00:05:13 nope just HSS 00:05:23 what SFPM were you running? 00:05:24 it was fine when the coolant was right 00:05:55 the speeds I use with HSS would give blue chips but not fireworks 00:06:06 about 200sfm 00:06:49 maybe it was a little more 00:06:58 not sure what the rpm is 00:07:09 it was a junk cutter anyway, no big deal 00:07:16 what happened exactly? 00:07:22 glowing chips? 00:07:31 yes 00:08:04 the tool is fine where it was at the top half of the cut, but burnt up (missing) at the bottom half where it didn't stay cool 00:08:24 hard to believe it was just lack of coolant 00:08:51 it was .3" deep on .25" plate, so the points are still there but there's a notch missing on each flute, up a bit from the end 00:09:03 you were milling along the edge? 00:09:13 no, through 00:09:20 along the edge it was fine 00:09:35 through = along 2 edges at once ;-) 00:09:47 one BIG edge 00:09:58 or did you have some kind of backing underneath that kept chips and coolant from flowing thru? 00:10:13 nope, nothing under it 00:10:29 I could see milling 0.24 deep in a 0.25 plage being a problem, since the bottom of the slot is blind 00:10:39 the cutter may have been crap, it's unknown and marked china 00:10:42 but if its a thru slot, why didn't stuff flow donw into it 00:10:42 down 00:10:55 I guess I had it aimed wrong 00:11:19 may have been too low, and mostly hitting the plate and not the cutter 00:13:13 jepler: you around? 00:16:08 I'm not used to dark at 7pm yet... it seems so late 00:16:17 any progress on your cnc conversion? 00:16:23 sucks doesn't it 00:16:26 no 00:16:31 yep, sucks. 00:16:33 I went out shooting ducks today 00:16:38 but, we'll get used to it 00:16:49 do you eat ducks? 00:16:58 shooting pixels 00:17:20 ? 00:17:26 oh a video game? 00:18:32 http://jmkasunich.com/pics/wood-duck-male-1058.JPG 00:18:49 oh, I get it 00:19:00 that's good, because ducks are cool 00:19:22 wow you sure caught his colors 00:19:56 I spent about 2-1/2 hours in the park today, shot a couple hundred pics 00:20:06 sorting thru them now 00:21:11 there were 6-8 _serious_ photographers shooting them too 00:21:29 serious = lenses that cost as much as a nice used car 00:22:13 ha 00:22:40 not snobby though (which was a bit of a surprise) 00:22:54 got a bit of usefull advice from one of them 00:23:08 that is a little surprising 00:24:02 it was 00:24:25 the advice was - get as low as possible when shooting birds on water 00:24:55 that does sound like good advice, I never thought about it 00:25:11 there's a footbridge over the pond, I was crouched down on it 00:25:20 would up laying on my belly instead 00:25:28 cradek: what was the steel like to begin with? was it saw cut? 00:25:32 lens maybe 16" above the water 00:25:56 DanielFalck: CR bar, not cut 00:26:24 so not flame cut or anything real rough 00:26:27 not sure if it was sheared off something 00:26:29 nope 00:26:34 that's good 00:26:40 and not hot rolled with scale 00:29:56 cradek: your sfm might have been too high for HSS. I'm seeing around 110 fpm in a table I have here 00:30:11 for plain carbon steel 00:30:14 http://jmkasunich.com/pics/mallard-head-1109.JPG 00:30:35 I usually use 100 fpm for HSS on steel 00:30:49 DanielFalck: yeah it was too high. I switched from 375 to 625 endmill and didn't reduce the rpm 00:30:54 moltrecht 'machine shop practice vol 2' 00:31:35 I have been looking for a wall chart that has all those magic numbers 00:31:50 if it would show dia vs rpm, even better 00:32:17 http://its.fvtc.edu/MachShop3/SpeedCalc/feedratecalc.htm 00:32:31 if you're mostly using HSS, there are only a few surface speeds to remember 00:32:43 100 = HSS on (mild) steel 00:32:57 jmkasunich: I use some carbide too, but that's easy, maybe 3x the hss value 00:33:04 200 = HSS on aluminum (can sometimes go a bit higher) 00:33:12 50 = HSS on tough steel 00:33:23 this one's a better chart than the last: 00:33:24 http://its.fvtc.edu/MachShop3/SpeedCalc/SpeedRPM.htm 00:33:29 its not like you're trying to shave a few seconds/pennies off of each part 00:35:01 wikipedia: 00:35:06 http://en.wikipedia.org/wiki/Cutting_speed 00:35:53 drat - got a beautiful pic of a male wood duck, with his reflection in the water 00:35:53 I know what I can program for you for Christmas now : ) 00:36:15 but the head is missing from the reflection - I framed it poorly 00:36:31 ah, darn 00:36:53 lol, caught another one scratching his chin with his foot 00:38:07 thanks guys, I'll remember 100 and 250 00:38:53 its trivial to make a spreadsheet with cutter dia in one column, and three more columns with the RPM for 50, 100, and 250 SFPM 00:38:59 print and hang 00:39:45 http://jmkasunich.com/pics/wood-duck-scratching-1118.JPG 00:42:43 http://jmkasunich.com/pics/wood-duck-flapping-1136.JPG 00:44:37 seems like I could make a graph with rpm vs dia. a particular SFM would be a diagonal line on it 00:44:49 it could be that log/log would be best 00:44:59 yep, I've seen charts like that 00:46:09 I have no idea what software to use to make that :-/ 00:46:35 tkinter of course! 00:46:38 thats why I've just done the spreadsheet one 00:46:51 DanielFalck: autocad! 00:46:55 gnuplot 00:47:31 fenn: I was afraid of that 00:48:26 use Axis and write a gcode program to engrave the numbers and the graph 00:49:00 using apt360 to generate the g-code of course : ) 00:49:01 I wish all the shots were focused this well: http://jmkasunich.com/pics/duckeye-1149.JPG 00:49:10 you can see the railing of the footbridge reflected in its eye 00:51:14 jmkasunich: you must have a lot of pixels... 00:51:22 10M 00:51:29 nice phots 00:51:33 photos 00:51:33 bout the same as Jeff's camera I think 00:51:51 I'm only showing you guys the good ones 00:52:42 nice thing about digital is that you can throw away a hundred and not waste money 00:52:52 yep 00:53:06 best thing to happen to photography since ... ? 01:06:18 well this isnt too hard: import Gnuplot; g = Gnuplot.Gnuplot(); g.plot(Gnuplot.Func('x**2')) 01:06:45 fenn: I've mostly got it, just trying to get the labels I want, etc 01:07:19 i was messing around trying to figure out why i couldnt do 'from Gnuplot import *' 01:08:18 "because the module and the main class have the same name" 01:08:22 d'eaux! 01:08:39 they should make the module lowercase then 01:15:53 jmkasunich: just saw your photos .. nice 01:17:14 bbl 01:17:29 make M3.1 be "set spindle speed in SFM for the current tool" 01:17:37 or S3.1 or whatever 01:18:01 no, wait - you know what I mean (even if I don't) 01:18:18 jmkasunich has quit 01:19:03 jmkasunich has joined #emc-devel 01:53:38 * jepler remembers to try his "developer edition" CD .. and it is finally getting to the live cd desktop.. 02:03:16 jepler: did you see my macro shot?
