CNC Machining a steel part with TPC and HPC tools | Hermle C400 | trochoidal

Just Machining - 08
In this video I will show you the CNC machining process of a steel part including iMachinig Jobs (trochoidal), HPC drills and end mills, and a nice parting off technique.
The part will completely done in one setup. The last surfaces will be sand papered.

[@BavariaCNC]

Hi! that is a good point I will try to bring that in to the next video. Thank you.

[@fabianbrock]

That's something like 24 tool changes for a ~50mm long part. That makes 2mm part per tool change :D

[@BavariaCNC]

the part is just 38mm :) this is why threads and reamed holes are expensive, but good

[@fabianbrock]

@@BavariaCNC so 1,5mm per tool change. Love your parts, keep making awesome videos, please. 😀

What are you going on about, with length per tool change? That's a needless specific.

[@mjshorty19]

Your customers are okay with those finishes and chatter on the outsides of the part? Or was this just sped up for filming purposes?

[@BavariaCNC]

Hi Michael, I know what you mean. But it looks much worse on the video then it is . You have to keep in mind that the part is pretty small and I film with a macro lens to get it in frame :) Anyway the part is being stonewashed in the end and then customers and I are happy :)

[@elanjacobs1]

Parts like this make me wonder how much tool change time could be saved with something like a Robodrill or Speedio

[@micgalovic]

Compare chip to chip times of the machines, multiple by the number of tool changes and wonder no more

[@elanjacobs1]

@@micgalovic Good point. Hermle spec sheet says 6s chip to chip, Robodrill is 1.3s, Speedio is 1.4s. I count 23 tool changes, so that's 29.9 - 32.2 seconds lost.

[@SaSaraSpanu]

The time won between tool changes will be lost in much lower feed rates in roughing. Robodrills are not very rigid.

[@gerrit2107]

@@SaSaraSpanu for the pretty small tools used on this part it would be fine i think, but you might be right

[@BavariaCNC]

i agree that for this part a robo drill would be very good. I don’t know how much tools they can hold but if they can handle tue amount it would be great. I was looking at a machine like that but i took the Hermle as I also have much bigger parts to do so the c400 was the way to go. but robo drills are amazing and if I would get one I would take one from Häberle cnc @haeberlecnc

[@NasenGuyng]

at high speed machining, you didn't use coolant for filming purpose or it's better not using coolant at all?

[@powylamywany8978]

It depends from the tool and manufacturer. YG-1 says you shoud use coolant with all of their V7 (4 and 6 flutes), Tungaloy on the other hand recemends dry cutting for their VariableMaisters and Sandvik says that in normal steel you shoud pretty much only dry cut with some exceptions. Unfortunately, i have no experience with Hoffman, so i have no idea if they didn't use coolant for filming purposes. Baisicly, you want to use coolant with low cutting speeds, low feed per tooth and hard steels and you don't want to use coolant with high cutting speed, high feed per tooth and softer steels. On some tools it can couse thermal cracking which leads to a very quick wear of the cutting edge. I have even seen a situation in witch a coolant combained with high feed endmill coused the tool to melt. Using and not using coolant is a very hard issue and yuo have to mostly relay on manufacturers recomendations and your own experience.

[@Holzf43ller]

Das kommt mir ein bisschen exzessiv mit dem Material vor. Ist das Hauptsächlich zu Anschauungszwecken? Ich meine, es geht bei dem Prozess nicht um Effizienz sondern um das Endergebnis, klar. Aber wäre schon interessant zu wissen wo Vorführung anfängt und welche Schritte auch mit einem Werkzeug hätten gestaltet werden können statt mit dreien.

[@BavariaCNC]

Servus, das ist tastächlich so produktiv gelaufen. Material ist mein Standardmaterial, da ich ungern kleiner 20mm arbeite.

[@policebox1092]

[@powylamywany8978]

Nice work. How much time does it take you to pragram this kind of tool path? And please make more videos.

No lubricant for the form tap ! I was waiting for the SNAP. Hard to avoid the tool smash in the work holding jaws. That would be the program path not avoiding fixtures?

Hi Thor! from scratch to full cycle run probably half a day.

HI, I didn't see any so far =)

[@hoju1301]

Whats the total cycle time for the part? Or is this the real cycle time in the video (~10mins)?

[@BavariaCNC]

I really show the whole process, so the 10 minutes are the cycle time (10:30 I think)

[@Bizob2010]

Do reamers give tighter tolerances on hole diameters?

[@bobbywright3479]

Yes, the hole has to be good before you use the reamer but it will produce a precise diameter. You can buy reamers in any size you need or have one made for you.

[@BavariaCNC]

@bobby wright described it perfect, so no additions from me :)

Cool part but the cutting data Is wrong ... After 20 Min in cut you have to replace all the endmills ... 0.16 fz? If you mean without the chip thinning effect ok , but in this case the workholding Is not stabile , you hear that , It tries to pull the workpiece in to the tool
