Something definitely looks wrong with your G68.2 lines. It looks as if they have the post setup for a C Axis machine, rotating around Z.

The order of rotations for Eulers Angles should be Z, X, Z again. The J's look good but the I's don't

Gotter figured out.

I J and K were ok

My A moves before g68.2 lines have been coming inverted +,-. When I fix this ,the code is seamless. the machine only uses B180. to correct pre positioning that is out by more than 90. deg. in A. That is why it took so long to find the trouble.

the problem probing at angle may not be the lack of software it seems...

If not, it may likely be connected to my post processor not agreeing with the machine!

I have been getting movement out of travel on the g68.2 line. the B axis on the head wants to08.nc turn upside down!

In case your curious...  

The V536 file is code that worked for another dept. found on this machine.

I have the team at inhouse solutions looking at it for me. I'm sure we will get it straight.

turn off LV3

IDK what that is... lol I am still learning g-code after 20 years!

this VCF has 3 meters of X , so if u r not close to position, it will often b out of range after g68.2 .

we r getting probing software Tuesday.

thanks again.

s

good to know.

Looks like we r ordering software... it did the same thing.

I did need linear movement pre positioning to get within the range of motion for the offset/ angle. before g68 . (top mapped approach point)

but thanks for clarifying things for me. We were not sure how to tell if the software was capable or not. looks like not.

s.

Please check this code and let me know what is wrong, or how to fix it.

This is a bore measure path p9814, but I will need a boss measure code.

Here is the not working code that I tried...

Thanks in advance for any reply.

Steve.

Also , as I have had to explain to the one guy,... to state the obvious.

If chips are left to get sucked into the tool, there becomes a big problem.

Still !! after years of rereleases !

We have request #R-14452 logged to add support for a separate min radius for the finish pass."

That has been on their agenda since  January 2019!!!

maybe it is good in 2022? I doubt it.

If any, what would be the drawbacks of using dynamic tool paths?

Be careful with "dynamic contour"... If you use the finishing path. It ignores the min. toolpath radius and plunges thru material that it just finished carefully leaving out of the path! Still !! after years of rereleases !

I need my W to hang out all the time to clear the collision zone in misc. values

so I am constantly repairing my tool paths, going back to push this "set to op defaults" button.

what good is the default if you have to keep calling it up manually?

mc 2020 now

LOL  we r finally cutting !!

but I was off when they had to do final setup and use my file.

it is running ok but I was unable to get my hands on, to do a proper fine tune.

so it squeals a bit... all is well , but no real feedback here.

I'm on an old Toshiba boring mill now.

thanks again to Everyone who chimed in.

MasterCAM software, I can't understand the meaning of drive surface and drive curves in MasterCAM. Please give me some guidance.

they r what drives your toolpath.

c-plane front or side...

But when he loaded My config on his computer

Sounds like one of those problems that a toolpath can get that is in the "backbone" of the file like a corruption.

u may need to build a whole new config. and toss the old one. I had config. issues that persisted after repair installation.

until I got a diff. PC. 

Hope u can keep most of your definitions and such. Good luck . 

easier to ignore the issue? who can say

Alt+F9 is the keyboard shortcut to toggle the gnomon display.

hey that is cool, I have never seen them show up in the top corners, showing c-plane and t-plane.

thx.

I set up a part on the face plate to interpolate the same hole in two different rotational positions.

I use marker inside the hole to see where it touches and adjust accordingly. Doosan has a spot in parameters where u also need the location input besides your Offset settings. they need to match.

There is a way to get the readout to show movement, if it is out, as u rotate the trunnion , but idk how.

the same toolpath with 2d Dynamic as I did 2d Contour.  I don't see an option anywhere to limit the toolpath to a boundary

Sounds like a partial chain with contour is what u need, just break the long leg to isolate the aria better.

Or use Opti-rough like The Millman said.

Where there is a shadow , there must be a monster, better keep looking!

  we have shadows when laptop is running other monitors. 

I haven't seen any monsters yet but I  keep checking over my shoulder.

I wanted a drill intended for aluminum. 

no such luck here. Just the cheap old HSS jobber drills.

do u have any idea what kind of cutting speed can I get away with on crap drills?

I've been using close to 200 but not over yet...' how  much more can she take Captain?'

thx

S.

For sure, I will let u know , but I have no bench line as I do one off work almost exclusively. I sure it will be better than a standard YG four flute XL.

I'm sure they r value... ,   that's why I can have one. LOL

SAFETY THIRD!  HAHAHAHAHAHAHAHAH.  that is good sht! 

thanks .

I really like the YG-1 Alu-Power endmills for Aluminum.

Thankyou all for the great thread! looks like Alu-power wins for today. the purchaser offered it up.

interesting reading here. all I can offer is my appreciation.

tried their Ti end mills

do u mean the yellow coating? should I go with thru tool or coated?

will a rougher be worth it? if I need a .3 deep cut with a dangling tool length?

thx again.

Good morning all, I have a project outside my typical work experience.

100 pcs of extrusion to mill . the part is about 4" tall with .3 wall thick.

I think that a three flute endmill is the way to go but the Question is which one?

about 5/8" or 3/4" dia. likely needed. I did prototype the job but , chipping everything away took for ever. 

So I'm thinking of cutting out chunks now. 

thankyou.        s.

Plus, I probably don't see the behavior that annoys you, because I'm constantly "Overriding my Autocursor settings".

For selecting wireframe arc centers > hit "C" on the keyboard

For endpoints > "E"

For Midpoints > "M"

For Quadrants > "Q"

I used that C a million times...

 then I  pretty well gave up on those for unreliability! another huge irritation!

 how do u get them to work properly?

maybe it was that old PC I had?

"grumble grumble".

some one had the same question, I read the response...

it was just another software for robots as far as I could see.

sorry. I have used MC for over 20 years and never heard of it being used to control a robot.

that said , u can make 3d code follow your geometry with Contour 3d... what r u after?

I thought 2021 was even better.

I have tried 2021 on another work station... it took about 5 minutes to see the first thing that bothered me.

u can no longer approach an arc slowly and lock onto the arc rather that the solid unless there is no solid under your cursor. I don't like to use solid geometry for tool paths because it is unpredictable and can spontaneously change. I had to figure out another way to isolate the arc geo. I used the arc filter for that project. just add another click or two. that is how it goes now a days just add more clicks for everything! why? simple work just keeps getting harder to accomplish.
