That’s some very tight programming. Nicely done.

[@davidg3944]

Love the stability of the cut. No bad harmonics, just clean, consistent chips. Only downside is the mess the steel needles make when you try to run them through the chip conveyor...

I'm noticing how the linking moves between each toolpath is fully 3 axis motion, as long as there is no stock in the way. It's a tiny detail but really cool since most of the time there's a Z retract before positioning X & Y to the next lead-in.

[@MrLembnau]

Yep its so the tool doesnt rub on the floor during the linking move

[@themonkeyproject]

​@@MrLembnauhe's talking about the moves between toolpaths. Not the transitions between each step over.

[@taylorcurtis6187]

A lot of cam software has options to keep tool down or limit g0 rapid movements

[@powylamywany8978]

Why did you do everything with one tool? Use a face mill at the beginig and ball at the end and you are down to 4,5 min and extend your tool life.

[@mjshorty19]

Was not remotely worried about cycle time. I was just messing around and wanted to only load up one tool for this part

[@Mike-ff7ib]

A tool change didn't seem necessary to me.

[@steinhausenzg2025]

I agree with you, I would also add an end mill and a spherical cutter. And it would be cheaper in relation to the price of the product. A 20 mm end mill costs $140

[@CncFrezar]

Very good job👍

[@ipadize]

which CAM program did you use? Those Linking moves look sick

[@3073Sean]

Very cool tool strategy!

[@nigels6786]

man I miss machine work too bad the money wasn't there here where I'm at. I'm doin line work now

[@davidawaters]

What’s tool life like at 1350 SFM (5/8” at 8250 rpm)? I need to do some experimenting I think. I’ve been running more like 400 SFM.

Study chip thinning

[@brandonrenwick9125]

1018 or any 1000 series of steel are the aluminum of steels. you can really feed it hard and go very fast. uncoated carbide is prolly good at 5 or 600 sfm but anything with altin alcrn tialn coatings your talking 1000+ sfm. that coating produces a thin layer of aluminum oxide on the tool at high temperatures. which resists wear to the edge. which is why its better to mill steels with air blast only when using those coatings. using coolant cools the edge too fast and chips it up, fracturing the coating until it breaks away. which snowballs into a mess quickly. because you no longer have the oxide being produced if there is no coating.

Одной двадцаткой 🤔 интересно)) а мы бы начинали с хай спид 25 и заканчивая фасончиком 😁😁

Nice chips)

Hello experts, do you recommend which machine for milling hard steel for a budget of 6000 dollars? THANKS

[@Dillybar777]

Spend the 6k taking your work to a shop. No worthwhile machine for that much money

[@pmsilvei]

Wow! 🤤

[@andrewlozinak273]

What machine is this

[@mjshorty19]

An old Mazak VCN 530C
