If the customer will accept the blend, I would be trying to complete most of the surface with a large ball or bull nose. Then blend the corner with a smaller bull nose tool, and finally finish the last 1mm with a 3mm ball (or whatever size the inner rad is)
However, I think I would probably go...
The actual shininess of the result can be very hard to dial in. You will need to play with stock to leave and amount/concentration of coolant and surface speeds. You might need more RPMs to shear the material, or a sharper cutter, etc? I might think you want a slightly smaller stock to leave...
Your step seems too high? I find that with a 12mm, my magic chipload for a mirror finish is about 0.08mm or less. H&V suggest about half of that...
So I might be expecting you to be under 0.03-0.04mm chipload for finishing...?
Hi Jordan. I did write a private message to you as well. However, I don't really understand your answers, given the other advice here?
For example, here is a rather nice 12mm end mill being held in a 20mm hydraulic holder:
That endmill is from hoffmann and has a small corner rad and the...
Hi, just to be clear, I didn't mean that this was a sensible test. I was just pointing out that when we are talking about measuring microns and putting 50lbs of force on stuff, then it could be moving for reasons other than backlash
I meant only that if you push the whole machine then it will...
If you just push about that hard on the sheet metal outside, do you see similar deflection?
I wonder if you aren't just distorting the whole machine?
On my S700, if I put my hip against the door and push firmly in the Y axis direction I can see microns of movement relative between spindle and...
This is my low tech solution to the same problem. I find them easier to use like this since they don't rotate and then kind of jam on the Y covers (as they do if they are inside). It does need 2 hands to tighten is the only minor disadvantage
The only shorty I have is the 0-10Nm baby torque...
Can you show a photo of such a thing?
I've the Orange Vises and I simply added long extension bars to some long depth sockets and I've several of these that I use on the torque wrenches and socket wrenches (and I have another on a drill for spinning things quickly). This means that the things...
But note that the tools, work offsets etc are stored in similarly named files. So if it's helpful you can pull down say TOLNM1 and copy over the data using a spreadsheet to convert from TOLNI1 (I think that's the correct name)
Actually digression: I find editing stuff on the machine such a pain...
Exactly this!
I'm happy to share my macro to do this. However it's for a Speedio (Fanuc alike G-code controller).
I insert the call as a "manual NC" line at the top of my Fusion setup. It may sound terrible but you can measure your XYZ in CAD and generally you only have 2-3 options (you need...
Speedio owner here. I spent some time playing with this on my machine with some M6 cap head counter bores.
I drill the through hole to size (even bought the correct size drill)
I then played with plunging a smaller end mill into the hole and cutting outward at constant engagement (plunging at...
I think the benefit comes from switching the machine to run in metric. I don't think that calibrating in metric offers any benefits as such
However, whilst I'm not doing high accuracy work, by and large I tend to see work come off my Speedio and measure to within 0.02mm of minimal, without...
In imperial you can only command the machine to 0.0001", which is 0.0025mm
However in mm you can command the machine to 0.001mm
You can pay extra to get an extra digit. So if you command it in inches then that gets you movements to the nearest 0.00025mm. My thought would be that just switching...
Oh my word! That's insane! Tell us more!!
Question: Why do we need a 20mm to do something like that? Seems like a 12mm tool should be sufficiently strong enough to get into the 100-150 cubes range. And assuming you can do that cut on a 16k spindle, then by definition the tool forces must be...
That Fraisa looks impressive! That's a 100 cubic inch cut
For quite a bit less money (but still expensive) I like the Hoffmann slotmaker. The manufacturer claims you can ramp up to 45 degrees (?!). They come in long length or shorter length with CTS.
Here's a 75 cubic inch cut with a fairly...
Tips are £100 here... $120 ish... I scrapped 3 in quick succession before I figured out that G31 trip is a "lethargic deceleration". Something like: I tested it repeatedly without trouble at very high speeds (like 30,000 mm/min), but with the over-travel set below the point the probe would...
I'm not totally in agreement here actually?
If we assume that the probe stylus is your "crumple zone", then you have a fair bit of safety barrier before you smack the probe in a Z move, assuming you are running in G31.
So my preference/argument would be for speeds somewhat proportional to the...
