[02:55:59] <gloops> vertical dovetails and box joints must be cut from both sides, to avoid breakout from the cutter passing through
[02:56:05] <gloops> that means - hand coded
[02:56:40] <gloops> and that means thinking about it, which is something im not used to
[03:03:44] <gloops> actually i think i can do this with software, instead of pocketting, i can cut a series of lines from either direction
[03:05:54] <XXCoder> wouldnt you be able to deburr it anyway? or is breakout something different
[03:06:18] <XXCoder> also wouldnt you just enter then leave both sides so end up with no breakout
[03:07:52] <gloops> with wood theres a good chance it will chip or splinter when coming out, it needs to enter the face on both sides cutting in
[03:08:34] <gloops> i got the sim working with cutting lines - any pocket i try to cut it always leaves cutting out
[03:11:33] <XXCoder> cool :)

[03:53:31] <gloops> yep got that working, still some arithmetic and use of array and copy etc but quicker than hand coding
[03:54:28] <miss0r> mornin'
[04:01:46] <XXCoder> nice. hey
[04:07:50] <gloops> rain all day here
[04:08:29] <XXCoder> same
[04:08:45] <XXCoder> here is experencing very dry season so far
[04:09:00] <XXCoder> only 1 or 2 rains a week when normally its rain in least once everyday at early fall
[04:09:09] -!- Rob_H has joined #linuxcnc
[04:14:18] <gloops> it was like that here earlier in the year - getting back to normal now
[04:14:42] <gloops> although 20c forecast next week - a good bit higher than average i think
[04:15:45] <gloops> 20C is like outdoor swimming weather, getting towards winter now
[04:15:59] <XXCoder> 68f interesting
[04:16:12] <XXCoder> here its all week below 60f
[04:17:02] <gloops> if its going to be hot every year ill have to move north, i seriously cant stand it
[04:17:59] <XXCoder> heh cold weather body here, summers suck for me
[04:21:59] <gloops> 70-80F - very nice, 80-100F+ - you can keep it lol
[04:22:35] <XXCoder> lol
[04:22:49] <XXCoder> here summer in that range tend to last 6 to 8 weeks
[04:35:50] <miss0r> I just got my new tool box.. My leather midwife style bag is starting to also allow for larger tools to fall out the holes in the bottom :) So, now I am replacing it
[04:35:57] <miss0r> i've had it for 20 years.. :)
[04:37:19] <miss0r> the new one has pneumatic/hydraulic cylinders to help open and keep the lid open :D
[04:45:47] <XXCoder> nice

[06:07:42] <jthornton> morning
[06:09:10] <XXCoder> hey
[06:10:38] <jthornton> I still haven't tried to boot to windoze on this laptop lol
[06:14:02] <XXCoder> I wonder if you need a grep rescan'
[06:14:21] <XXCoder> umm not grep forgot name of it
[06:14:24] <jthornton> what does that do?
[06:14:39] <XXCoder> it checks your system for bootable partions and rebuilds your boot menu
[06:15:33] <jthornton> I'm on Linux Mint 18 now
[06:16:23] <jthornton> can't seem to get google to work as default for firefox and yahoo sucks
[06:16:25] <XXCoder> ah yes! grub
[06:16:36] <XXCoder> you need to go to website to add google
[06:16:42] <XXCoder> its annoying
[06:17:39] <XXCoder> https://www.linuxmint.com
[06:18:21] <XXCoder> steps if it dont seem to work https://connectwww.com
[06:19:25] -!- decor82 has joined #linuxcnc
[06:21:05] <jthornton> finally got it, damn pain in the ass
[06:21:58] <XXCoder> yeah
[06:22:22] -!- gloops has joined #linuxcnc
[06:23:09] <gloops> slight power issue there..windows doesnt handle being switched off very well
[06:23:48] <jthornton> I'd reboot now but I'm testing some chicken python code
[06:24:41] <jthornton> code needs to adjust the open and close time of the door each night at midnight + 1 minute
[06:26:18] <gloops> to keep up with changing daylight times?
[06:26:30] <jthornton> aye
[06:27:42] <jthornton> door must close at dusk and for now open at dawn until 10 hours of daylight then start adding extra light
[06:28:32] <gloops> so youll need something to control the lights

[06:29:31] <jthornton> I'm using a RPi with a terminal block plugin thing and a relay block
[06:30:04] <jthornton> I have a RPi now controlling the door and lights but I'm trying to improve the code
[06:31:35] -!- decor82 has quit [Client Quit]
[06:37:15] <jthornton> the other thing I'm trying to sort out is how to ramp up the light time from a date 5 minutes per day until I reach 14 hours then hold that light time

[06:59:44] <gloops> last cutting disc burns away at this stage of proceedings
[07:17:53] <Tom_L> 55�F Hi 56 hmm, that doesn't sound good
[07:19:12] <Tom_L> neither does the weather map
[07:19:26] <XXCoder> 57f high here
[07:31:43] <gloops> hmm, i am foreseeing problems with this bandsaw now
[07:31:58] <Tom_L> how so?
[07:32:00] <gloops> if this 'gantry' racks, the blade is gonna come off
[07:32:04] <gloops> https://www.youtube.com
[07:32:21] <XXCoder> that looks so safe
[07:32:26] <gloops> hes using a big handle to push both sides the same time, i reckon ill have to do that
[07:32:53] <Tom_L> you making one of those?
[07:32:54] <gloops> XXCoder lol, bandsaws arent that dangerous
[07:33:23] <gloops> Tom_L similar idea, i got a scrap bandsaw to start with, so got the wheels and tensioners and everything
[07:33:59] <gloops> it just dawned on me, if the gantry racks the blade will just slip off
[07:34:22] <XXCoder> yeah rhats why I was being sarastic on it being safe
[07:34:27] <Tom_L> the guides should keep it on
[07:35:14] <XXCoder> tenitis special https://www.youtube.com
[07:35:16] <gloops> Tom_L maybe, but if one side is twisted at a different angle..it takes ages to trim the wheels to get the blade to run on track
[07:36:18] <gloops> blade making is a huge pastime now
[07:36:22] <Tom_L> looks like he adjusts the height on each side separately
[07:36:53] <gloops> yeah ive got two old vertical screw jacks for that, ill just raise and lower each side on those
[07:37:18] <Tom_L> seems it would be harder to get even cuts
[07:37:30] <gloops> ive got 1 piece of 6 inch box section for the spine of it
[07:37:50] <Tom_L> i suppose he planes them flat after that
[07:38:30] <gloops> yeah, put them through planer thicknesser when dry - or surface them on cnc router
[07:38:36] <Tom_L> and sawdust collection in the tracks will affect the board thickness too
[07:38:46] <Tom_L> i'd address that problem as you build it
[07:39:03] <gloops> im running mine on skate bearings along two pipes
[07:39:05] <XXCoder> brushes tp move chips out of way would work fine
[07:39:26] <XXCoder> just use paintbrushes very cheap ones cut off handle and screw it in
[07:40:25] <gloops> i think he improved that machine a lot in later videos, but daft as it looks, oak boards like that are expensive, hes shelling off $20 a time there
[07:40:45] <Tom_L> i know
[07:40:46] <XXCoder> oak takes a bit to grow
[07:42:24] <XXCoder> that video is interesting so far
[07:42:55] <Tom_L> https://www.youtube.com
[07:43:05] <Tom_L> he collects some of the chips in a bucket
[07:44:37] <gloops> thats what you want yeah
[07:45:15] <gloops> the dust will run with the direction of the blade on the bottom - always comes out same end
[07:45:48] <gloops> thats a ood set up on a trailer - straight to the wood
[07:45:51] <gloops> good
[07:47:54] <gloops> quarter sawn hardwood - get your chequebook out
[07:48:11] <Tom_L> or your saw
[07:48:33] <gloops> lol, well see if i can get this crazy idea to work
[07:48:52] <Tom_L> not crazy unless it fails
[07:49:34] <Tom_L> i kinda like that trailer saw
[07:50:05] <gloops> that is an ideal way to do it yes
[07:50:19] <gloops> tree blown down? hitch up the saw off you go
[07:50:44] <Tom_L> now that jthornton's got a few wood tools i feel he needs to build one of those :D
[07:51:38] <Tom_L> and the forest to go with it...
[07:52:08] <gloops> useful thing to have
[07:55:39] <Tom_L> those last few cuts he does are the 'money' cuts
[07:56:47] <XXCoder> the decreasing sizes cuts?
[07:56:55] <jthornton> Tom_L: what's that?
[07:57:18] <Tom_L> https://www.youtube.com
[07:57:21] <Tom_L> bandsaw mill
[07:57:42] <XXCoder> is it part where he cuts turn it cut, turn back so on?
[07:57:53] <Tom_L> i believe so yes
[07:58:17] <jthornton> my neighbor has one

[07:59:18] <XXCoder> restores em
[07:59:22] <jthornton> that one is too short
[07:59:33] <jthornton> missed that

[08:03:20] -!- jthornton has quit [Quit: Leaving]
[08:03:22] <XXCoder> fixed grub?
[08:03:24] <XXCoder> bah late
[08:11:37] -!- jthornton has joined #linuxcnc
[08:12:15] <jthornton> took two tries but I've booted to windblows
[08:12:20] <XXCoder> yay
[08:12:24] <XXCoder> so you fixed grub eh
[08:12:31] <jthornton> clock is off
[08:12:41] <jthornton> didn't do anything to it
[08:13:21] <XXCoder> if I recall linux simply ignores board clock besides using it to keep time syched
[08:13:30] <XXCoder> so board time mau be off
[08:15:48] <jthornton> I'm in windblows at the moment
[08:16:08] <jthornton> time to switch back to linux

[13:41:10] <fragalot> miss0r: got the new drill press. I'm sure the table alone weighs 100kg+ https://photos.app.goo.gl
[13:42:43] <fragalot> miss0r: I believe the table might have been part of a 5-axis mill.. gears & bearings have been recently replaced by previous owner, just before he 'upgraded to an RF30'

[13:51:03] <hetii> Hi guys :)
[13:52:46] <gloops> evening
[13:54:04] <gloops> that looks a bit 'machinemart' fragalot
[13:55:28] -!- modrobertaX has quit [Ping timeout: 245 seconds]
[13:56:53] <hetii> I whant to build my first CNC machine for milling as a hobbyist PCB or maybe some front panels for my devices. So far I order such items square Linear guide sets: goo.gl/hV6etv and 2.2kw water spindle: goo.gl/WTokXw. Now wonder about step motors, this one will be fine? goo.gl/tJofau
[13:58:31] <hetii> btw the table and rest will be made from wood
[14:00:37] <gloops> yes i think so hetii
[14:01:02] <gloops> ive got the same on mine basically
[14:01:54] <gloops> btw you need a different breakout board that one wont operate the spindle
[14:02:05] <gloops> it is only a $5 thing
[14:02:19] <fragalot> gloops: machinemart?
[14:02:35] <gloops> cheapo chinese?
[14:02:36] <hetii> I also found such motors: http://goo.gl but they have higer impedance
[14:02:52] <fragalot> gloops: if you can call a €3000 drill press 'cheapo', sure
[14:03:19] <fragalot> it feels pretty good, so no complaints from me :-)
[14:03:19] <gloops> what that? never
[14:03:26] <fragalot> other than it being a BASTARD to lift
[14:04:17] <gloops> hetii i think 425Oz-in is a typo
[14:04:24] <gloops> theyre 425 oz
[14:04:57] <fragalot> gloops: mine's the "pre sold out to china" version. this is the china version you can get today: https://www.huvema.nl
[14:05:00] <hetii> gloops, so with one order, the first one based on 23HS9442 or the second one on 23HS2430B ?
[14:05:13] <fragalot> less gears available, lower power motor, and thinner column
[14:05:25] <fragalot> so I'm pretty happy :-)
[14:05:44] <gloops> what are you getting for 2k there?
[14:05:57] <fragalot> small format gear drill press
[14:06:14] <fragalot> the one I have has a 180mm quill travel, rpm range from 100 to 3000
[14:06:33] <gloops> hetii im not an expert on individual motors of this kind, they both look ok tbh, pretty standard issue steppers
[14:06:37] <fragalot> and because of the head moving instead of the table, the damn thing is rigid as hell
[14:07:09] <gloops> still seems expensive to me, but what do i know
[14:07:18] <hetii> Well I just read that lower impedance motor are faster
[14:07:25] <fragalot> hard to find cheaper geared drill presses, gloops
[14:07:33] <hetii> but cannot say about other pros or cons
[14:08:46] <gloops> https://www.ebay.co.uk i mean these are known for being top notch drills
[14:09:27] <fragalot> belt driven, and not benchtop size
[14:09:34] <fragalot> whole different class of machine
[14:10:06] <hetii> about board what you suggest to use for linuxcnc? I would like to start from LPT, and if need more GPIO then can add second LPT port or build some usb2gpio module based on AVR
[14:10:30] <fragalot> hetii: i'd suggest that if you can, that you go with mesa cards instead of LPT
[14:10:31] <gloops> personally id go with the first motors hetii, 2 psus
[14:10:50] -!- grotius has joined #linuxcnc
[14:11:09] <gloops> i wouldnt go with mesa for first cnc, it will be hard enough to get it running from lpt
[14:11:21] <gloops> you want the mach3 board hetii, hang on
[14:12:25] <hetii> well i`m not sure if I need use mach3 software, personally I use linux all the time so preffer linux based software
[14:12:36] <gloops> https://www.ebay.co.uk
[14:12:47] <gloops> yeah its just commonly known as the mach3 bob
[14:12:54] <gloops> it works on any software
[14:13:14] <gloops> exactly that board, not the blue one
[14:13:54] <gloops> this has got pwm and relay for the spindle control, the 1205 board in that package doesnt - you cant control the spindle with it
[14:15:18] <gloops> as used by the late and great Ichsguckslive who came here for 10 years or more
[14:15:32] <gloops> he built 200+ machines a year with this board
[14:16:31] <Tom_L> that one has analog spindle control?
[14:17:16] <gloops> you got the pwm for spindle speed and relay on/off
[14:18:55] <hetii> gloops, about electronics things I can create any board that I will need, so suppose this will not be a problem for me. Of course not including FPGA for driving motors but here I will use lpt and other things for the rest
[14:19:31] <Tom_L> good board for the 7i92..
[14:19:45] <gloops> not worth making for $5 but im sure your skills will be useful
[14:20:05] <hetii> btw I also plan to control all parameters of VFD spindle from PC
[14:20:12] <hetii> so can write even additional software for it
[14:20:15] <hetii> if needed
[14:20:17] <gloops> yes thats what im saying
[14:21:06] <gloops> you can control the spindle from linuxcnc - ui and or gcode with that board
[14:22:16] <hetii> ok so have a next question about LinuxCNC sofware, is it expose some API system that I can call and add for example some cameras inside my CNC machines that will recognize object by using https://opencv.org library and based on those data do some positioning
[14:22:57] <hetii> so for eg by opencv I could detect edges or my material
[14:24:12] <gloops> yes i think so
[14:24:48] <gloops> you might need 2 parports if you start adding more hardware
[14:24:54] -!- grotius has quit [Quit: Page closed]
[14:25:47] <gloops> a lot of these questions are answered on the forum
[14:26:10] <hetii> yep, simple hardware with IOs capabilites will not be a problem :)
[14:28:00] <gloops> https://pico-systems.com
[14:28:35] <gloops> http://wiki.linuxcnc.org
[14:30:21] <hetii> cool ok, so first I need to build my machine and then will add new stuff to it ;)
[14:30:48] <gloops> any design ideas for the mechanical build?
[14:32:52] <hetii> well, this is a subject where I need to learn more ... But suppose at the end, the gate will be static and I will just move table.
[14:33:51] <gloops> probably as well if building with wood
[14:34:45] <hetii> yep but I have 1m and 70cm linear guide and in my setup I plan to use 70cm for X and 1m for Y
[14:35:44] <gloops> id think it makes sense to have the bridge the shorter dimension
[14:35:48] <gloops> for rigidity
[14:36:15] <hetii> and all will be build like here http://i0.wp.com
[14:38:34] <hetii> well.. my plan to exchange X an Y is because i`m not sure if I will have enough space my my desk :)
[14:39:03] <hetii> but from rigidity perspective you have right
[14:42:04] <hetii> BTW, I also I plan to add there 3D head and 15W Laser that why I want to have closed box and cameras inside and control my machine over LAN
[14:42:20] <hetii> so don`t need to have glass window in it
[14:42:49] <gloops> hmm, a 3 in 1 machine
[14:43:17] <gloops> i wished id built mine vertical now to save space
[14:43:24] <hetii> yep
[14:44:24] -!- ve7it has joined #linuxcnc
[14:47:20] <gloops> Loetmichel made a few wooden machines, still uses one i think
[14:47:26] <gloops> he cuts aluminium with it
[14:53:58] <hetii> gloops, back to board, why blue one is broken ?
[15:03:47] <gloops> ahh yes, i thought you might ask that
[15:04:35] <Loetmichel> gloops: i dont use a wooden machine any more, but yes, cutting alu on a wooden cnc router is perfectly doable if you make the gantry rigid enough
[15:05:23] <gloops> i remember seeing some vids you posted of the plywood machine Loetmichel, worked fine
[15:05:31] <Loetmichel> indeed
[15:05:35] <Loetmichel> and not a small one ;)
[15:06:13] <Loetmichel> https://www.youtube.com <- that video?
[15:08:04] <gloops> yeah look at that, better than a lot of chinese ones you can buy
[15:09:40] <hetii> well in my case when I talk about aluminum I suppose it will have something like 1.5mm thickness
[15:09:54] <hetii> so I really don`t plan to milling a car :)
[15:10:35] <gloops> 2.2kw spindle will eat it
[15:11:40] <hetii> and also wonder if I should order some machine like CNC3040 from aliexpress but I read that is to soft and not capable for my easy tasks
[15:11:49] <hetii> so I decide to build it from wood
[15:11:53] <Loetmichel> hetii: i do a lot of 1,5mm Alu on a cheap chinese CNC 6040 at the company
[15:11:56] <Loetmichel> works fine
[15:12:25] <Loetmichel> https://www.youtube.com <- desk its mounted on could be a bit more stiff though ;)
[15:12:25] <hetii> I`m a bit scary at the moment cause the plan was to have small machine and I end with huge one
[15:12:47] <gloops> mine does cut ally - slowly, but ive only got 800w spindle
[15:12:52] <gloops> thats the bottleneck
[15:13:06] <Loetmichel> not here
[15:13:35] <Loetmichel> the 800W spindle still has loads of torque reserves when the gantry starts to bend
[15:14:03] <hetii> wow, why this machine so dancing :)
[15:14:14] <gloops> well mine doesnt exactly rip it up with aluminium
[15:14:18] <Loetmichel> Whats the word for "springy bend, returns when force is no longer applied?"
[15:14:20] <gloops> makes a very nice job though
[15:15:39] <Loetmichel> hetii: word of advice: if you have ANY chance to make room for a 6040 sized machine: do it. The 6040 is a lot stiffer than the 3040 because of using supported rails in Y
[15:15:56] <gloops> good with mdf though lol https://www.youtube.com
[15:15:56] <Loetmichel> and CNC routers are ALWAYS to small
[15:16:16] <Loetmichel> you WILL outgrow even the 6040 pretty quick ;)
[15:17:14] <Loetmichel> gloops: maaan, that blue smoke... you should use a sharper bit and/or less RPM ;)
[15:17:36] <Loetmichel> hetii: i ran into size restrictions a few times...
[15:17:53] <Loetmichel> http://www.cyrom.org
[15:17:56] <gloops> it was one of the first cuts i did with it, any tool to hand, just testing it, i only use 3mm bits for sheets now
[15:18:05] <Loetmichel> http://www.cyrom.org
[15:18:35] <hetii> Loetmichel, interesting, I read that 6040 is less stiffer then 3040 at least in Z
[15:18:36] <Loetmichel> http://www.cyrom.org
[15:18:38] <Loetmichel> :-)
[15:18:53] <Loetmichel> hetii: it is a bit less stiff in the gantry
[15:19:06] <gloops> take things a bit slower now https://www.youtube.com
[15:19:22] <Loetmichel> but the long axis (gantry moving) is weak on the 3040 because of the unsupported rails
[15:19:29] <Loetmichel> wich is more of a problem
[15:19:54] <gloops> this gantry is about 60 kilos, 2 x 425 oz motors, a wooden gantry would fly with those steppers
[15:20:07] <Loetmichel> i can assure you that it is NOT a problem to mill alu with a 6040 though
[15:22:56] <hetii> That`s why I order linear guide.
[15:23:32] <hetii> So far I spend around 1000$ for motors+sppindle+vfd+linear guide kit
[15:23:53] <Loetmichel> for that price you would have gotten a complete CNC 6040
[15:23:54] <hetii> so at the end I suppose will pay less then 6040
[15:23:57] <Loetmichel> ... just saying ;)
[15:24:55] <hetii> but not with 2.2kw spindle :)
[15:25:35] <Loetmichel> https://www.ebay.de
[15:25:42] <Loetmichel> they are cheap as fu** these days
[15:25:52] <gloops> https://www.ebay.co.uk
[15:25:56] <Loetmichel> no, with 800W spindle, which is perfectly sufficient
[15:26:17] <Loetmichel> indeed, gloops
[15:26:38] <gloops> ahh to just unpack and connect up lol
[15:26:46] <Loetmichel> yes
[15:26:50] <gloops> instead of 2 months torture in the garage
[15:26:55] <Loetmichel> yes
[15:27:17] <hetii> hehe :)
[15:27:36] <Loetmichel> needs a few end/ref switches and a bit of tinkering/adlusting, but basically you can have it running on the same day as delivery
[15:27:37] <gloops> still, you dont learn anything that way
[15:27:45] <hetii> well. What I can say, i`m not sure if do It right but at least will try ;)
[15:27:47] <Loetmichel> oh you will ;)
[15:28:00] <Loetmichel> learn things i mean
[15:28:23] <Loetmichel> hetii: point i tried to make with my enclosures are that even the 6040 gets "to small" fast
[15:28:42] <Loetmichel> dont start with the 3040, its simply too small for a lot of things
[15:31:40] <hetii> ok will keep that in ming
[15:31:43] <hetii> *mind
[15:32:12] * Loetmichel is trying to convince the boss to allow me to build one with a 2m by 1m travel so we can utilize full "small sheets" from the sheet metal dealer and dont have to pay for cuts
[15:34:17] <hetii> make sense for me :)
[15:36:57] <gloops> theres one thing, when i show people stuff i made, they say - yeah but you didnt really make it, the machine did
[15:37:07] <gloops> then i say yeah - but i made the machine as well
[15:37:16] * Loetmichel is a bit careless sometimes... dont do things like that if you like your fingers: https://www.youtube.com
[15:37:37] <Loetmichel> gloops: same here ;)
[15:37:55] <gloops> anyway got to go out bbl
[15:40:52] <hetii> hmm I just realize that should also add some very simple hardware based protection if my spindle will go outside allowed range
[15:41:16] <hetii> cause if software will freeze there will not be chance to stop it

[16:27:20] <Loetmichel> acre!
[16:27:29] <Loetmichel> nope, that would be a bit big
[16:27:45] <XXCoder> engrave entire sides of building facades lol
[16:28:52] <Loetmichel> i once help make one that used crane rails and -beam in a 8m by 15m workshop though...
[16:29:02] <XXCoder> imange the challenges of building such a big machine. even if it would be rated for light engraving only.
[16:29:07] <Loetmichel> was fun.. not that accurate on the other hand ;)
[16:30:43] <Loetmichel> at that size it starts getting more useful to have the machine move on the surface of the workpiece than build a machine that can enclose the workpiece
[16:30:48] <XXCoder> cool :)
[16:31:00] <Loetmichel> you know, like an excavator with a chisel head
[16:31:26] <XXCoder> yeah theres small machines like that

[19:09:58] <XXCoder> interesting https://www.youtube.com
[19:10:06] <XXCoder> cermic endmill
[19:10:24] <MarcelineVQ> ceramic is getting a lot of attention recently it seems, dunno if that's reflecting industry or there's just more vids about it now
[19:11:34] <XXCoder> dunno, previously there was only inserts. entire endmill is new
[19:12:32] <XXCoder> dang
[19:12:33] <MarcelineVQ> wonder what metal that is
[19:12:39] <XXCoder> metal part is all chipped the fuck out
[19:13:04] <XXCoder> thats very heavy abuse
[19:13:06] <MarcelineVQ> the first comment I see here is pretty great "No chips just lava"
[19:13:20] <XXCoder> thats great for roughing
[19:13:31] <XXCoder> then can use regular ones for finish and last much longer
[19:14:00] <MarcelineVQ> I'd be concerned about heat given just this video to go on, not that one should go on a video, and especially just one video
[19:14:11] <MarcelineVQ> Overall it doesn't help that ceramic doesn't mean much as a descriptive word, it only means the binder involved in making it isn't carbon
[19:14:18] <XXCoder> actually ceramic loves heat
[19:14:22] <XXCoder> hotter the stronger
[19:14:28] <MarcelineVQ> It's the part I'd worry about heating :>
[19:14:54] <MarcelineVQ> Carbide isn't any more descriptive though I guess, since all it means is that binder is carbon hehe
[19:15:00] <XXCoder> yeah lol
[19:16:36] <Tom_L> https://www.sandvik.coromant.com
[19:16:41] <MarcelineVQ> It should ring alarm bells that this is official advertising however, given the cutter's state at the end
[19:16:57] <XXCoder> it seemed to be very very heavy abuse
[19:17:06] <XXCoder> going way too fast on very hard metal
[19:17:14] <MarcelineVQ> Which metal was it?
[19:17:22] <Tom_L> ^^
[19:17:30] <XXCoder> its certainly not alum but not too sure.
[19:17:50] <XXCoder> "nickel based alloys"
[19:18:06] <gregcnc> ceramic endmills aren't that new
[19:18:16] <XXCoder> like intcel I guess
[19:18:26] <XXCoder> really? it was first I heard of
[19:18:32] <MarcelineVQ> it is inconel appearantly, Inco 718
[19:18:38] <MarcelineVQ> that is fast for inco <_<
[19:19:08] <gregcnc> kennametal has been making them for years
[19:19:09] <MarcelineVQ> Not that we haven't seen carbide do that speed, but it's comparable at least
[19:19:45] <MarcelineVQ> And explains the chipping
[19:20:42] <XXCoder> inconel sucks
[19:21:00] <XXCoder> I engrave lots of disks of inconel and tool life is brief, around 40 to 60 parts
[19:21:16] <XXCoder> stainless steel disks I could run over 1000 just fine
[19:21:32] <MarcelineVQ> This might be okay with flood coolant, the dust would be awful otherwise
[19:21:56] <XXCoder> cermtic tools would explode when hit with coolant
[19:22:12] <gregcnc> right ceramic runs dry
[19:22:14] <MarcelineVQ> Is that the case currently? They used to say that about carbide
[19:22:16] <MarcelineVQ> dang
[19:22:27] <MarcelineVQ> that's terrible, the dust that would come off this part...
[19:23:14] <XXCoder> wouldnt be worse than fiberglass lol
[19:23:59] <MarcelineVQ> fiberglass shops are scary :(
[19:24:12] <XXCoder> thankfully work dont run lot of em
[19:24:24] <XXCoder> just 3 varations of one part
[19:24:31] <MarcelineVQ> Can't even stand the resin vapor smell near production shops, lets alone imagine the horror of shops where it's cut
[19:24:54] <XXCoder> it runs on only machine that can run em as fiberglass "clay" would kill chip conveyers
[19:25:16] <gregcnc> 2013 https://www.youtube.com
