The Harvi I-TE never gets old. Watching that 90% stepover for that long of a distance was amazing. The Heller has so much power too it's incredible! I can't wait to see you push the limits of this thing Barry!
@@importanttingwei7747 It has been gone since we got the Doosans in. Makino is good machines but they don't feel the same way Titan does about education. Titan wants to make sure that all the education we bring to our community is completely free and Makino didn't want to support that so we went in another direction.
When Titan said at the end that in the real world you would want to use coolant... But why (except for chip evacuation)? Would this not thermal-shock the cutter? I don’t know what kind of coatings are on the Harvi EMs, but coatings like TiAlN only gets hard when it gets hot; if I add coolant I’d lose the hardness I’d otherwise gain.
@@chulangmo5799 pretty sure it will only thermal shock if it is already hot. If you use continuous coolant from the start it should never reach those high temperature.
The technology in these CNC machine I’ve been watching you for about five years for years whatever it is add from what you had then to what they have now it’s just unbelievable keep up the good work and yes watching tons of chips come off is absolutely jaw-dropping
I have been watching your channel for years now. I'm a 5 year machinist and trying to keep up with all the best tips to improve production. I understand radial chip thinning and trying to maximize depth of cut to get the best MMR. What I can't find is a formula for RPM change when lowering your radial tool engagement.
For my study I went to a company which is almost fully automated with automated vehicles to move already clamped workpieces. It is amazing to see this stuff in real life!
Easy on my old Alfred Herbert 12B with its 24"chuck and lots of HP. 15 ton monster turret lathe I had last century. Date on the bed was 1944, my birthday. Solid cast iron. Push a 3.5 " spade drill down it with 0.5" cut on the o/d. You are spoiled Titan.
You can’t seee this in every cnc shoop. I knew that you would like Siemens, it is for far away the best control.Please make video wher you compare this machine with ex ibarmia with HH.
Good idea. Barry, please compare the most common NC-controls with each other, such as Siemens, Heidenhain, Fanuc and maybe even the Hurco control. P.S.: I agree with you. The Siemens control is the most userfriendly control in the market.
Please do a comparison run of the endmill removing material and a comparison run by turning it off. What’s the cycle time of each run ? I’d love to know…
I actually like that idea! I did it this way just to alleviate some of the torque concerns I had with turning, and thought it might be a good pointer for the times you run into a similar issue
It definately depends a lot what exactly are doing, what material, what is the diameter... Milling small diameter aluminium, where you need high RPM will be way faster than turning. Keep in mind those rotating table do not spin as fast as a lathe; it's often just above 1000rpm or even less than that on bigger ones. But large stainless or superalloy parts where you can't use high rpm, it may be way different.
I was just doing some mill turning today and was wondering. How do you calculate the Rpm you need to rotate the part at as well as the speed of them endmill to find out the chip per tooth and sfm. We were going full depth and milling out. ALarge pocket on a lathe feeding the tool into the material in the X and rotating the subspindle.
I'm sure that he didn't hurt himself. He knew what he was doing. A snowflake like you, I would recommend that you keep your little girly hands safe inside your pockets.
@@barrysetzer Barry you legend. It’s not always you haha. But maybe it’s an Australian thing, we are more used to a normal tone of talking that’s more chill haha.
What was this one programmed with, and with which package? Was the initial post processor good from the get or did it require a few tweaks? KEEP IT UP!
Please help me with my math here? First cut is 2.250" x 0.075" x 300IPM = 50.625 cu"/min........second cut 2.250" x 0.675" x 30 IPM = 45.5625 cu"/min. Am I missing the rotary speed or something here?
The MRR here is difficult to calculate because the feed and speed given are for the back end of the tool that is cutting the larger diameter, whereas the tip of the tool is moving through material more slowly
Very observant! I calculated this by measuring the outside diameter, then the finished diameter. the difference was 63%, so I reduced the feed at the tip of the tool by 37% so that the back of the tool was moving at the desired feedrate!
I have no need for that machine at the moment but I want one. How does the flute edge hold up on the harvi end mills? I've got a cast part with an interrupted cut that I keep getting nicked flutes on with our general purpose carbide end mills. I'm interpolating on a not so rigid setup and holding =/-.0006, which is easy peasy. Will the Harvi hold up? I need a solution...
They are absolute beasts. Did you see the one we did where we started full slotting with one that was already chipped to death from running for 2 hours in inconel? Monster......
I have a question for everyone out there in the machining community. I need to cut an M20 X 4 ID acme thread about 1.5 inches deep in 416 stainless. Tapping is not an option as we will be building a lot of these parts. Does anyone have any thoughts or ideas?
Climb milling is done 99.9% of the time these days… especially on high level machines. One simply reason is that all chips are behind the cutter instead of blasting in front, where the cutter would be running them over and breaking. There are times to conventional mill but ya… Climb Milling is King.
3% is very low if youre using a good quality cnc mill and spindle. For steel and aluminium we generally use between 10-60% depending on doc and other factors. What kinda material and cutter do you use?
