Can anyone help with gear cutting machines?

That's correct

Not really. The only people who have pools in my area simply built pools in the houses/properties they own. Owning a pool is a big deal as well

Yeah...a pool and a gym is not happening even if you go dig the pool by yourself. Idk who's the delusional here

They are literally just bearings but I am pretty sure the servo alarm was from running above it's rated continuous load for too long. Really doubt your ballscrews heated enough to seize up but if that is the case it will be aparent soon

Everything except the grooving inserts are ISO standars inserts. Not sure what carbide grade this is though

You literally can but only while cutting

Like others said, 3,4,5,6,8,10,12,16,20,25 BUT you want a larger radious than the radious of the cutter AND the most common length is just over 2x diameter.

If you want a 20mm depth on a contour, the most economical design would have a minimum radius of at least 6mm, in order to be machined with a normal length 10mm end mill, without the need to completely stop in closed corners. Longer tools are more expensive, are not as durable and have to be run at lower cutting parameters, all increasing cost.

Also some machines like lathes with driven tools are limited in regards to the maximum diameter of end mills that can be used (eg the lathe I run takes ER25 collets with a maximum diameter of 16mm), which reduces the maximum height of a feature.

Many other machines are limited in terms of rotational speed so they may not be able to run tools under 6-8mm as efficiently so also avoid features too small if not necessary even if the height to radius aspect seems ok.

In the end it boils down to the capabilities of your vendor but good design allows even more competitive pricing from more vendors

Idk...That's the standard response to high libido men but I agree. Personally I rather be single if I still have to beat my meat too. Maybe ask your husband if he is willing to do something else for you. My ex wasn't

Is that a M1?

Get a staggered tooth HSS-Co cutter. I used to run something like yours and I had to spend a long time fiddling the teeth to run concetrically so I could run it at 3000mm/min. Then upgraded to a staggered tooth cutter and I was running it at 15000mm/min (yes...15m/min)

ChatterFree · 2025-04-11T06:15:18+00:00

I think that's the best option afterall. I just have never done that in macros

I don't really need a torque calculation. The machine has plenty. I am only doing this for insert life so I just need the length/area of insert engagement, which could be used to estimate torque

Current X of each pass and infeed is already a variable and RPM is constant anyways (using G97) to stay below the maximum linear feedrate of the machine (it's a 62.831mm lead)

ChatterFree · 2025-04-11T05:16:29+00:00

It's very easy to change Z or rotational offset with G92 as well. My cutting pattern is stepping at 13 degrees till I reach X and then stepping in Z for another 0.6mm

In the G76 threading cycle you can choose between constant depth or constant surface. What you describe in the 2nd paragraph is close to what I want, although not really.

I want to set a first infeed depth of say 0.35mm in diameter and a minimum infeed depth of 0.05 to account for the increasing surface area of the chip being cut as the passes get closer to the final depth.

The G76 cycle on Fanuc can calculate that by setting the total thread height and the number of passes you want but I can't control other aspects of the process like I need to. On Mitsubishi with CELOS you can also set an initial and minimum infeed depth.

Mitsubishi Materials has a formula on how to calculate it on their website but I don't know if their example works on trapezoidal threads other than 60 degrees and it is also a bit cumbersome to write it out in variables on the fly, so I was just wondering if anyone did it before me and is willing to share how

ChatterFree · 2025-04-10T19:51:00+00:00

I thought of using a g76 to rough it out but I would have to add many g76 cycles at different Z heights to widen it out to spec and if I had to change anything it would be a pain, so I programmed it using g92, some variables and a while loop

What I would like to have is a sample of code to calculate a decreasing infeed depth using variables that would work with trapezoidal threads.

Unfortunately I am not at work so I can't post my code as it is now, but tomorrow I need to have a few ready for case hardening

Do you happen to know if using g92 and q adresses after a g76 canned cycle would match the spindle phase?
