THANKS GCPDE.

THE CODE LOOKS FINE AFTER i CHANGE THE SWEEP TO 90 DEGREES.

HI,there,

the generated G-code shows compensation occured on arc move, whne I use 3/8 ed bore a .8" hole, I checked "start at center" and "perpendicular entry", but didnot check "output arc move for helixs", in control definition, "helixs support" is actiived.

how to fix this porblem.

thanks in advance.

Eric

THANKS ALL YOU GUYS,

LEANT LOTS

thanks for your inputs.

Hi, there,

I have a job which has a flat bottom hole of 8.500mm (0.3346)" with depth of 44.5mm (1.750)", tolerance is 0.001", the internal surface finish is 1.6um, Can anyone give suggestions on tooling,RPM,feed,depth cut? the material is Al6061 T6.

thanks very much.

Eric

Please someone send me a copy at [email protected]

thanks very much!

thanks Cris and Ron,

I made a mistake when I set Minor dia. for OD thread. now it is fine.

Another question, do you think I need do multiple cut for M20x1.5 on Aluminum? I set cutting speed 400sfpm and feed rate 8.4 ipm (chip load .003"/tooth), is the setting OK?

thanks

Eric

Hi, everyone,

firs time to mill a one start right hand M20x1.5 OD/ID threads, I searched the forum, there was no answer to my question, so post it here,hope you guys can help me.

Qeustion:

first I mill a boss 0.7815" in Dia.,and the set thread mill Dia. is 0.57"(from the supplier, also I checked it by cutting), I set the Major D 0.7815", pitch 0.059055, use "wear" bottom up,

why there is no cutting? I did not set wear to any value.

thanks very much.

Hi, guys,

1/8-27 NPT, through hole, aluminum 6061 T6, HAAS VF-2(20 HP) Rigid Tap, spiral flute tap, what is the suggested RPM?, do I need tap ream the hole?

thanks

Eric

To 35K CHIPPER,

Could you please tell what kind tap holder you use?

Did you ever use Lyndex Positive Drive for such small tap? how deep for 1.4mm tap?

do you use lub. oil while tapping?

thanks

Eric

use short drill bit drill first.

then use long TiN drill peck drill, Q around 0.04, feedrate around 0.0006.

I did two holes around 1.75", no broken

Hi,John

our machine is HAAS VF-2,I am sure the machine set up for rigid tapping.

do you think the Lyndex Positive Drive maybe a factor?

I did not try to use a ER holder to hold the 1-72 rolling tap.

thanks

Eric

Hi, John,

I use Lyndex positive drive holder for 1-72 rolling tapping, through hole, 7mm deep, rpm 1440(feedrate 20), A9 lub. it was broken when finish 10 holes.

do you use positive drive? is it not "rigid" enough? I noticed that there is still a little movable space, not like in ER collet chuch that the tap was deadly holded.

Eric

Hi,Guys,

I have no experience on rigid tap, my questions may be stupide, pls don't laugh, , help me, thank in advance.

• What type tap is suitable to CNC Rigid Tap on CNC? Rolling form tap, spiral fluted tap?

• What type holder is used for rigid tap? Positive drive holder, normal collet chuck holder? Which is better?

• For small thread hole, such as,1-72 7 mm deep, 2-56 12 mm deep, what tap is the best choice?

• I noticed that there is a little bit material pushed out when forming tap a through hole, how to deal with this?

• When working on Aluminum and Stainless 306, what type tap do you use? And how is about the feedrate?

• When rolling tap, do you use lub. Oil ? How do you handle the coolant in the drilled hole?

• What brand tap do you suggest?

• how to do 1/8 NPT tap on Aluminum, peck tap or not? what type tap do you suggest to use?

Eric

I will have a job, material is Kovar, size is 3.8x4.0x28mm, in the center there is a hole dia 2.6mm, and on the side there are two 0.6 mm holes,

what kind of drill suggested to use, cutting speed and feed ,peck depth?

TIA

Eric

Hi, guys,

Have you ever met this problem that you can not chain some geo., but when you turn off MC and run it again, it is ok.

what is the problem? is this a bug?

thanks

Eric

Q1: how to delete the import entities

Q2: why some toolpath icon color change to gray and green after finishing the recongnition

Q3: how to import the geo to a different level

thanks

HI,

better to use wear instead of control, and set up proper "tip offset" especially at the confined space

we did lots prototype jobs in our company, and sometimes there are only a few geo different in the two different version, and the toolpath are already built up, my question is how to replace some geo in the file I have already built up instead building up all the geo again.

thank you guys. I got it.

to John and Axela 06

I still have question about the file you upload, why did not you chose "coordinate method" instead of "tool plane method" in the first transform? and why did not transform both controur and pocket in the transform? is there any other problem?

Eric

HI,Eric

It did not work.

can you please just draw a pocket with hole in the center, then transform them in the way that I mentioned.

thanks very much.

Hi, guys,

there are two vises on my vertical CNC table, in each vise I will machine 5 same parts,so I use transform toolpath, my question is that I'd like make the 5 same parts in the second vise, how to ransform the tooppath?

thanks

Eric
