is the break thru option turned on for one of your paths? i remember that stumped me in the past, or maybe the length comp is set to center on one and tip on the other?

LOGITECH M510

if you're really concerned about the stepover this seco tool r220.21-02.00-R160.4A has a 1.38dia flat section, .080 max doc, but the insert is only 3sided

and this one is similar to the kyocera with a 1.25 flat R220.21 -02.00-SC12.4A .085 max doc

i've also been in the same boat with the scallops they leave giving me trouble with subsequent ops

what i have done for high feed mills was use an optical comparator or a cmm to get the points, then draw the shape as a custom tool, heck you could use a height gage and some radius gages to get you close to the shape

most manufacturers will give you a reference radius to use, i dont think that method works very well (not a very accurate method)

ive also been machining 6al4v, once you get an established process with it, can you let us know how well the hf mill works and how long the insert life is? ive been kicking around the ideas of engagement milling and high feed cutters to speed up our roughing process a little bit but as of now its very reliable , were using a 3" r290 sandvik, and its slower but very consistent insert life

if this is what your're trying to accomplish, this may help, http://www.emastercam.com/board/index.php?showtopic=74938&hl=, ill be glad to help if this is the way you would like to do it

we have 1 hinge type on one of our 500mm horizontals the rest are scraper , the hinge does a terrible job keeping small or light chips out of the tank, its pretty ridiculous how bad it is , if we run the machine 3 shifts a day, every week we can get about 2 5gal buckets of aluminum chips out of a 170 gallon tank, the scraper type take a year+ to build up enough very fine chips to warrant a good tank cleaning

bolt them down, pretty much every mtb tells you to do this in the installation manual, case in point we have a couple doosan 500mm hmcs, their weight is 30,000lbs, when i send the y axis up to the top and rapid x end to end, there is a point on the reversal of x i can literally turn the jacking bolts by hand, i also had to increase the x axis acc dec times on all of them to keep it from literally jumping off the floor

ever done a post edit?

we get that snotty crap too on just one machine we have and its nasty as heck aint!!, it usually happens when sombody lets the concentration get too low for a while, then dump alot of concentrate in to compensate, im not sure why it does it

our shop uses chemetall 8620 it works good but not a great rust inhibitor

we've used castrol mb-50 at one point and it was the best semi synthetic that i've ever used, never stank and tool life was great!! its more expensive than the chemetall , but imo the true cost is less, i can give you a contact to call at castrol if you're intrerested

using that procedure to output the subs, and researching the mp documentation and surfing the forum , ive figured out how to make the post automatically number the subs incrementally from the main program , without having to manually enter program # for each transform op, which is definitely a step up from where i was a week ago!

anyway can anybody throw me a bone on how to make the subs post out separate file names instead of all in one file? ive been messing with it for a few hrs now and , i just don"t understand it, ive read the chaper on "file manipulation" and "how subs work" i just can seem to get it to work per the ref guide and haven't found anything on the forum about it that gives an example

my post is based on mpmaster

thanks for the tip djstedman that works great

have you tried increasing the toolpath and tool shape tolerances? when i have issues with stock models this seems to fix it most of the time, and sometimes i just have to delete the stock model and do it over again

whats the best way to get mastercam to output a toolpath as a subprogram? im running into some difficulties trying to figure out whats best,

i personally envision a misc interger/real post mod,

for example i have a toolpath group i want to post, there are 10 toolpaths in this particular group, 4 of them are too large to fit in the machines memory,

i go to the said tool paths i enter a value in misc interger\real (####) this would be an indication to the post that I want this tool path to output as a sub,

it outputs the main program with m98 p### as indicated by misc real\integrer in the correct sequence and i also get my subs as separate files named O### so i can load them onto the cf card and then load the main program onto the cnc

seems simple enough, but modifying posts is not my strong point,(i can do simple stuff, or if someone posts up thier logic i can usually figure it out)

im not really into cut/paste programs because its error prone and time consuming if your tweaking a program

ive looked thru mc to see if there was a better way to output subs but i can only find them thru the transform ops and drill cycles, neither of which apply to my situation

different size monitors/ aspect ratios did that from past experiences, ive had it happen in x6 and x5, all you should have to do is reload the tool bar state that you're using and it should be ok

what type of carbide drill are you using to tap drill the holes?

yea im pretty sure i did when i figured it out a while back, ill check when i have the chance

Anyone care to prove this out or let me know what i'm doing wrong?

i dont think you're doing anything wrong

I tried it as well and it does the same thing to me only on dynamic facing

incremental retracts seems to be using the clearance plane value instead of the retract value

if you want the incremental retracts on a dynamic facing style paths ive used a regular 2d core mill just picking one chain, and if u do set the min toolpath radius to 2.5% and zero stock to leave on walls, seems to work just as well for me

thanks for the response

yea the machines are equipped with ai-nano

ill check those parameters along with the firmware and pmc on monday

its not a keep relay i checked there

i was saving the ladder trace for last , im not going to be fast at doing that and was trying to get a part in production on friday, and i'm under the assumption that if it is pmc related i cannot do much about that, wouldn't it require doosan to fix?

i have one doosan dhp 5000 fanuc 18i that does not stop in single block when ai nano is active , is there a parameter that will change that ?

i have 2 other doosan dhp 5001s with fanuc 18i that do stop in sbk when ai nano is active

i've looked myself in the parameter books and cannot find a related parameter and have compared both machines parameters and couldn't find anything different relating to ai nano parameters

thanks for any input

Bob,

 

Also, if you are doing this on a HMC, you'll REALLY want to consider entering your starter hole with the opposite rotation.

The added issue of droop from horizontal mounting will make this a necessity.

That's they way I do it and it WILL save you tooling.

I've watched people try it without opposite rotation and have the drill edge bite and then it's busted tool that went into launch mode at terminal velocity.

ive never considered that factor, but i did just change all my macros to reverse the spindle on the entry, thanks for the tip

another tip for anyone is to slow the tool changer speed down, most machines have a mcode for slow tc cycle, in addition i slowed the slow tc cycle for our doosan hmc even slower in the machines parameters for smoother operation i had a few that broke off during a tc

it almost sounds like the machine is still in g93 inverse time mode dispite your G94 unit per minute mode

yea the g72 working like a g65 simple call

it is assigned (if my memory serves me) somewhere between parameters 9010 and 9020 on a 16 or 18 series im not sure about the 30 series so that it calls up a macro program 9010 or 9011 9012 etc...

you could also do a g66 pxxxx that would work like a canned cycle where it stays in the mode and just change the x, y and repeats the cycle, i dont have the post for that type but it is another possibility

ill collect the necessary files at work tomorrow and put em on the ftp when I have a chance

heres how my post outputs , if you want ill send you the post, macro, and control def it could be refined im sure but we dont do too much deep hole drilling

i know it says jobber drill i couldnt think of a file i have with a deep hole drill off the top of my head,

but i put the tsc commands in the macro for "g72",

the "S" is for the proper rpm, and the D is used to feed in from the r plane at 1.5 or 2.0 x the d value, then it kicks up the rpm to the S value and turns on tsc, feeds to z depth at F, then it backs off incremental .015, coolant off and spindle 150 rpm ,then feed out at 3 or 4x the F to the r plane

roger that, figured id throw it out there jic

i have noclue what this is at all but this line looks like it has a typing mistake

 

get_ent(&ptr, &e_ptr, &entity, SURF_ID|SOLID_ID, &bsuccf); !!!this one has a "b" after the & and before the "succf" , the other lines in your post don't have it
