What's the total machine time?

 

[wings_of_fire]

No idea. The feed rate was pretty good.

The machining program at 4:40 is something that can invite fatigue fracture in the ball screw material. A home machine shop owner should never use such cutting programs unless $ is never an issue.

So this is someone else's video? I thought you were posting something you had done when I asked.

 

[wings_of_fire]

Yes. It is someone else's video.

I did get a hunch that you thought it was me, looking at the way the question was asked...:lmao:

 

[wings_of_fire]

Most of you must have seen this 5 axis machining video

.

that was the first thing i thought. but you can see when hes squirting the coolant and blowing away the chips that the film is actually sped up.

Good observation!! "thumbsup"

It is clear that while spraying the speed of the video is increased.

The deep plunge and cut. I do that all the time on Krawlfreaks mill and have never had any problems besides him yelling at me to stop.

 

[Calderwood]

I wouldn't have asked about machine time if it wasn't obvious the speed of the video was increased.

Yes its obvious that he will yell...lol
Modern cnc machines are expensive on price and maintenance.

I had not realized the whole video was sped up because at some places he had 1x speed I guess and I though he was speeding up for cleaning and change over. The 4:40 machining process consist of fast circular movement and when a machine moves that fast changing direction, then the ball screw material faces higher compressive forces which can at some point over shoot its loading capacity and affect their molecular structure. These problems don`t show up immediately because they start slow and grow exponentially over time.

Those CNC machines are awsome 4 sure.

But personally i dont want to operate them, and thats proberly the reason i havent used my education as a machine worker mutch since i got it in 1987.

It is proberly allso the reason why my elbows are blown - shouldrs partly blown and my lower back have been blown for decades and ny upper back have been acting up under load for the past decade or so.


Getting old suck

What would your tool path be for that area?

 

[wings_of_fire]

What would your tool path be for that area?

Tool path can be anything that is logical to the CAM software and the inputs by the cam programmer. The two main things are feed rate and depth of cut. It should not exceed the limitations of the machine and cutting tool.

There are other number of important things to look out for as well....

In fact you are the one who will create cam programs perfectly with that vast machining experience you have. "thumbsup"

To operate it, yes age is hindrance.

I understand how the tool path is generated. I use rhinocam to generate mine and and am slowly learning manual g code inputs. I was asking how you would do the pocketing shown at 4:40 since you disagree with how it is being done in the video.

Last place i worked as a painter, we got a robot to do my Work.

Due to the cheap setup and shape of the gears i painted turnover went Down 300 % and use of paint whent up 200 %, and all the houres i had in surplus every day ( waiting for curring oven to catch up ) was gone, so i was not able to setup encorders and brakes for the guys who assembled the gears, and all the other Things i could do while waiting for the curring oven.

Machines and me only Work if i can sit on or in them and have 100% control :mrgreen:

I tried 1 day to feed a CNC lathe, damm what boring uninspiered Work, it was mutch more fun operating my manual TOS grinding machine at allmost same speed ;-)

35 mm K6 CNC isent as fun as 8mm r8 manual "thumbsup"

 

[tom@vp]

that type of milling is called trichoidal milling, its a new technique for roughing deep pockets at full body/full depth cuts that works well. we use it on certain cuts.

the program at glance did not look sped to me, but i could not sit though the whole thing it was hurting my ears and eyes to watch...

that machine wont live a 5 year life span running it like that...

I disagree with the feed rate at which its done.. Very bad for machine life.

But still not sure about the actual speed shown in it. The video has variable speed sectors I guess.
