Great video, I’ve won business after writing macro code from watching this video. Customer using macro code still today and is over the moon with his process. Thank Hoffmann
I love how different youtube channels use different terms for the same things. "30 percent stepover" aka "ae 0.3 x D" aka " 30percent RDOC". Some other people use absolute values insead of percentages. Just to add to the confusion.
I am using a 3/4 inch end mill to profile a flame cut 4140 block. DOC is 2.375 and I am wondering about step over and speeds and feeds for this type of cutting.....anyone help me out there?
At Protyp a saw a full slot, 16mm cutter with 32mm cutting length. (25mm width 50mm length) Very simple parameter to produce a slot. Put in parameter for one cut. then repet it. Very simple. There also showed a ramping processs to deep 30mm. After that there increased the diameter form 25mm to 50mm. With very simple parameter. It is possible, but there is better today.
can see benefits for stainless and other harder alloys however I work with a couple of guys who use this method of smaller cuts at stupid high feedrates and they are literally vibrating their spindles into dust and require refurbing every couple years at a 10 grand price tag
Completely agree, sorry forgot to mention that they use it on aluminium and plastics, by switching back to the traditional methods I eliminated the spindle wear problem and even reduced their cycle times sometimes by up to 50%. i've recently moved onto titanium and similar materials and the HSM toolpath is definitely the way forward
Guy Good As well as massively boosted productivity due to less time spent changing tools and higher material removal rate, as well as lower cutting temperatures and thus less need for cooling. Overall, the benefits outweigh the cost of more frequent machine servicing or replacement outside of highly specialized applications.
In my experience the tools actually hold up MUCH better because the majority of the cutting pressure isn't on the corners and the machine actually vibrates less with this style cutting

Hmm.....
Finally some useful information for viewers from a company. Thanks.
Seriously my brain just fell out of my head
Very nice video! I think you've done a great job showing the math to what is commonly know has high speed machining.
Are there some parameter tables that you can share.
Another question how is the contact angle calculated?
Worked for hoffmann group best explanation video i know

there is an ISO standard, but I'm pretty sure no one uses it cause they didn't learn it that way
great cam
is the Garant voice actor the same as the german cinema guy?

eh...I really hope that feed of .5ipt was actually .5mm pt.
5 tooth?
I saw this in 2006 is Zell (Walter Prototyp) So whats is new??

Yeah Walter is having several solutions, but Hoffman is Superior in Rotating Tools, I saw in India.
used by which software?
most modern cam software can do this.

Yeah, on smaller parts it's kind of dumb to use HSM methods as the feeds required to load up the tool properly make the table go nuts.
better for tool life. worse for machine life.
In a professional setting 10 grand is nothing over a two year period. Running just a few percent faster would make up for it. Speed is king.

In soft materials the only advantage is in deep slots, helps with chip evacuation.
what means FZ????
Hi, it´s the feed rate per tooth (tooth feed)
thanks
can you tell me how to calculate RPM and feed to high speed toolpaths?
What variables do i need to consider?
@@josedejesusmaciel2925 I know this is an old question, but I really enjoy this software, and it's relatively cheap...

come on fellas reduced tool wear at the expense of reduced machine life

+Guy Good And don't forget. Less cutting forces and vibration. Vibration is the number 1 killer of ballscrews...
+Kostas Froudarakis Thats why you should not use Weldon or Shrinkchucks. Just Collet Chucks - no vibration with the CENTRO|P from FAHRION
pfft...My Rohm hydraulic tool holders > those.
