As always, the proof is in the pudding.
-
The other thing that factors into this is the optimize stepup and stepdown settings in cut parameters
-
Stock models show cubic volume, so just compare the final one to the initial. HSM Advisor will give him MMR, which is necessary for his calculation, but it knows nothing about how much metal he started with or the cubic volume of his part.

Nice, I'll have to start using that. I wish the camera followed the chaining progress, though.

Probing a corner at an angle.
jpatry replied to Tinger's topic in Machining, Tools, Cutting & Probing
I would locate the WPC with a tooling ball, and probe that, instead of trying to locate on the intersects of angles on a skewed part -
Motion between Entry Motion and Dynamic Mill
jpatry replied to Metals and materials's topic in Industrial Forum
Yeah, too large of an entry helix creates some very janky stuff at the transition between entry motion and cut motion. From what I have seen is because it sees material on both sides of the tool, and conventional mills in the helix, and then has to reposition itself to climb mill in the actual cut motion. Reducing the helix radius always made this go away. -
Is this update out yet?

The other day I couldn't figure out why my stock model operations were taking cripplingly long times to regenerate. Turns out that someone had reset the thread limit back to 4 in the multithreading manager settings, after putting it back to 16 everything was back to normal.

Yes, Mastercam ships with a gimped version of Cimco, it's still good, but nowhere near the god tier of the real thing
-
Can you use a stock model as an intermediary?
-
Drill and Bore with same tool... with tool on centerline?
jpatry replied to amw's topic in Industrial Forum
Program the profile cutting to an offset contour, should achieve the same result, Will run on a single offset, but may also be confusing for whoever is setting up the job -
Eliminate Pluging of 3mm endmill -- Only come in from the sides!
jpatry replied to Tagmaker's topic in Industrial Forum
Yeah, the best you can do with the Engrave toolpath is use the ramp entry setting. Honestly, I wish Engrave got reimagined as a variant of 2D Dynamic or even OptiRough instead of what appears to be a variant of Pocket. -
I like the idea of the reamer. I'm still trying to convince the powers-that-be to buy at least a couple of those micro float tension-compression holders, but they still think putting taps in standard ER collets and holders is good enough.
-
I have noticed a radial discrepancy of roughly .002" between a contour chained on a solid edge and a contour chained on wireframe created on that edge. I know this has to be a chaining tolerance issue, so I'm curious where and what exactly are the settings for both of these?
-
Huh, so that's what happened to me the other day...

Haas probe for flatness in Z axis
jpatry replied to david's topic in Machining, Tools, Cutting & Probing
Neat, so I could interrogate 195 and 194 to pull an average z position -
Haas probe for flatness in Z axis
jpatry replied to david's topic in Machining, Tools, Cutting & Probing
With the Renishaw macros that are shipped with there is not a dedicated multisample probing macro to do what you want to do. You would have to take a Z probe sample and dump it out to a separate variable at each location, then perform the math on the sampled values. It appears that I am wrong, Millman has the solution -
It was left with a cylindrical collet installed, and that collet still slides freely in and out
-
Uhh, by default rapid moves are yellow, and feed moves are blue. Are you intending to drill in rapid, or what else is going on here?

How FUBAR is a Sandvik Corochuck 930 that won't tighten? Is it simply a lack of fluid? What fluid do these things even take, and what is the procedure for refilling them? The backstory is it was sitting in the tool storage rack unused for quite some time and it is unknown if someone fiddled with it during that time. What appears to be the fill port is a tamper proof torx, so there should be no good reason to loosen that instead of the 5mm hex that clamps and unclamps. But my suspicion is that is exactly what happened and fluid was lost.

As did I, and my hold on reality was irreversibly lessened

This is great to know. The company I work for has yet to bid on any titanium jobs, but they love to imagine themselves more capable than they are, and make promises that are often of dubious deliverability. And so, it's not a matter of if, but rather of when, thus I'd rather be armed with as much information as possible.
-
Is it because the material is quite springy and does not like to deform permanently in such an operation, or is it due to how titanium likes to adhere to other materials under such conditions?
-
What about form tapping?
-
Oh, I wasn't being naive enough to think I could get them to buy useful tools, I meant convincing them of the use of proper feeds, speeds, depth of cut, and stepover in dynamic milling operations. Okay, their website gave me a giggle... >>Ideal for more powerful machines such as HAAS In what universe? I work in a shop full of Haas, and it's like driving the plastic barbie jeep in the Baja 1000.
