I run mine at .005mm, but then again, my parts are smol. I also use it as a quick toolpath verification, to see surfacing cusps, etc. -
That seems strange. I could see it about cutting the time in half, but going from 10 minutes to 30 seconds is wild. Just be aware that on a lot of machines, adding microlift will noticeably increase cycle times.

Wireframe vs. Solid Chaining
Matthew Hajicek - Singularity replied to Camelot's topic in Industrial Forum
I do wireframe. In addition to leaving the toolpath intact when importing a new model, it lets me apply Kentucky windage to certain features, like a thin tab that deflects more than the other features being cut by the same cutter, or features with a single sided tolerance that need to be shifted from the model. More control all around. -
Yeah, for single thread. I was looking here: https://www.cpubenchmark.net/cpu_value_available.html#xy_scatter_graph I'm not sure which would do the Mcam benchmark faster. I know the price difference between $590 and $730 is insignificant when it's going to be your money maker.

Any reason you guys prefer Intel over AMD? I'm thinking that Ryzen 9 7950X looks pretty good.

PC Emulator
Matthew Hajicek - Singularity replied to Matthew Hajicek - Singularity's topic in Industrial Forum
There are use cases, such as if you have a bunch of old Mastercam files that you want to bring up to date, but have to move through an intermediate version for compatibility. I could also see it for the older, occasional user, like the guitar maker I worked for in the late 90's; he's mostly cutting wood, occasionally aluminum or phenolic for a fixture, doesn't need the latest, fastest toolpaths, doesn't make a new program very often, and doesn't want to have to learn a new interface. Staying on V9 will work just fine for him. -
PC Emulator

Ok, later in the video they say it can't handle dongles. Someone smart might find a workaround. -
This could be a solution for those wanting to run old versions of Mastercam or supporting software:
-
Since computers are generally good at math, they should be able to make it so when you switch units EVERYTHING is instantly converted.
-
It looks to me like you set your work offset X and Y at the center of the stock, not the center of rotation.
-
Your Xeon is only running at 2.6GHz. I've got a ten year old gaming box that's about double that. Mastercam loves clock speed, so the fastest i9 you can get is the best. I assume you're running off SSD's and not over a network? I'm still using X9. Does modern Mcam still have the RAM saver function? It recompiles the file to be more compact and efficient, clearing up the space that had been occupied by stuff that's been since deleted.
-
It's also critical that your work offset in the machine is EXACTLY at the COR in all axis'. Any error will be doubled when you flip the part 180 degrees. I dial it in this way: After getting it close with indicating and probing, I'll do a test cut on a piece of aluminum, with a skim pass, flip 180 degrees, and cut again. Measure across the faces. If it's .002" off, move .001" and try again. You can do this for both rotary axis' and get within tenths.

Modify the Stock Model

What do you do if you have to change the ops before the dummy ops? -
Modify the Stock Model
Matthew Hajicek - Singularity replied to cnc4hobbyists's topic in Industrial Forum
I'll just add a dummy op to remove the unwanted stock, and post-ghost it after updating the following stock model. Just remember to un-ghost it if you need to regen the stock model for any reason, and then re-ghost it before posting. -
I have yet to find any of my work that will tax a modern GeForce. Bone plates on a pyramid fixture, arrays of a hundred parts on high density fixturing, etc. I'm sure there's a limit where it makes sense to go Quadro, but that limit keeps moving with every generation of cards.
-
There's also the RTX A6000, for $4k.

Ok, what if the "barrel cutter" has a one million inch radius?
-
Would the software be happier with a barrel cutter (circular section)?
-
Or they'll think 1/32", but round it to .030", so I use a .050" endmill.
-
Well, I guess I learned something. I tried the same program, skipping the corner drills, and it worked just fine. Tool life is still acceptable.
-
I have some families of parts with pockets with 180 degree clearance corners, and I'll pre-drill those. Otherwise the cutter would be in a full slotting condition as it enters the corner. The alternative would be to go to a smaller cutter, but that would negatively impact cycle time. This kind of clearance corner, but deeper:
-
What did your reseller say when you asked them?
-
Still valuable, thanks for mentioning it. I'm making this decision now myself.

Is there a Long Cutter Rule of Thumb?
Matthew Hajicek - Singularity replied to [email protected]'s topic in Industrial Forum
HSMAdvisor can give you reasonable suggestions on cutting parameters to start with for cuts like that. Then once it's running, play with the overrides until it sounds best, then write down the actual feed and speed to put back into the program.
