We use carmex solid carbide threadmills with the taper on the cutter and don't have this worry with inputting the taper in the taper angle box..just curious what brand tooling are you using that has 13 teeth or are u counting every tooth on the cutter if so that sounds like a low amount..I find using 1 tooth to work better and to enter cut by start at top of hole and to enter and exit at center rather then leading in and out of hole with radius to prevent accidental gauges..I know it's climb cutting this way but less hastle and retracts in my opinion also some controls will error out with a arc lead in with wear turned on..I've been cutting threads for long time and all different sizes and pitches and find this method to be sure fire every time and great finish..doing it the way above I can see why people are intimidated by thread cutting and why everyone that runs across a job that requires thread cutting comes to me for advice..all about the right tooling and cutter dia.'s as well as the way you approach it and it's as easy as drilling the hole to be thread cut

All the articles I've read say cuts with ease but wasn't sure about the real world applications lol..thanks again

Has anyone had any dealing with drilling and cutting NAK55 steel. I have a project comimg up with alot of work and wondering how this stuff drills,cuts and taps..I use sumitomo carbide high speed drill and mill star insert cutters and just your regular run of the mill end mills with TiAIN coating. What is this material compariable to when maching and drilling.. Should I machine it as if it were a P-20 steel ?? any info greatly apprecited. Thanks..

its something in the software.. i have been complaining to the IT guy about it ever since upgrade to 6..never had this issue in X5. we have yet to install X7 due to all the issue that have been posted on here. X6 is up and running stable and cannot afford the down time due to bugs or crashes that may risk by the upgrage to X7..

thanks guys once I mentioned I was looking into it online they contacted our MC reseller and we are drilling holes now.. well he is lol..

Currently our shop has a ( deckel dmu 50 ) 5 axis or 3+2 not sure which, but the operator wants only to use work nc software to do the drilling on this machine and the posted path is often buggy and cant be trusted to drill unattended. I am wondering if there is a post that comes with the MC install that can be used on this machine to do drilling with or a generic post that can be modified to work. The operator says theres probablly not one available do to these machines being new in the USA. Im wondering if hes just telling me this to avoid doing any drilling on this machine or if hes even had our IT guy contact our MC sales rep to investigate the issue of getting a working post for this machine so MC can be used. Hes a die hard work nc guy but if its not going to do the job we need then in my opinion we need to use MC to do the job if theres a post available to work with this machine..thanks in advance.

we use these type drills from sumitomo with great results using TSC on our vertical machining centers. http://www.sumicarbide.com/prodline_drilling.htm

its internal threading and I have always done my threadmilling from top to bottom. Is this the wrong way of doing so because it works with no problems. as far as the m04 code for these particular cutters I was thinking just make sure and go ccw with spindle and to climb cut instead of conventional from top down..and thanks fo rthe info but please correct me if im wrong about normal thread mill cutters(m03) spindle rotation and weather starting from top to bottom versus bottom to top.I have only done about 25 to 50 holes using the thread mill path and had great success with right hand threads starting at top to bottom but never tan across using a M04 rotation cutter for right hand internal threads..also Im not sittting in front of my work computer it may default to bottom to top when climb cutting with a cutter spinning in reverse (M04) to produce right hand threads..for threads im new to I always do a test run in a scrap piece of alumunium before I cut them in the actual part so as to not scrap the part for im still learning the thread milling ans so far I like it just want to make sure I do it right.. thanks..

gonna be milling some 6mm standard threads in hardened s-7. using a solid carbide cutter. only thing different is the cutter says to run with a M04 instead of M03 in the nc code. do I need to change anything in my thread mill path besides the way the cutter turns. Currently I conventional cut and I start at top and go to bottom with my thread mill cutters but this a first with one that has to be run cutting in reverse or M04 spindle code. just looking for any info that any one has that may have run these types of cutters before when doing thread milling. thanks in advance.

having same problem since our IT guy installed X6MU2 on our computers the other day.. I am also noticing about a 20 sec delay once MC opens up before it will alow you to do anything. it says not responding until it gets unstuck..think im going to have the IT guy uninstall and reinstall X6 MU2 and see what happens.

no its all brand new and parellel to the table. all tools will repeat within .0002 sometimes not changing at all. so Im not sure where the .002 margin is coming from..machine is less than a yr old as well..its a toyoda fv1680..

yeah we actually had to get a new probe a few weeks back for ours quit on us but we installed it indicated it in flat within .0002 re callibrateed it and still get a .002 variance with tools..its not a big deal if you are aware of it but I would like to get it tighter if its possible.. I too touch off all my tools in the same manner as you described abouve.. anything 1/2 or above use the auto rotating feature and drills and smaller cutters touch off on center..

or is there a software that is good and worth the money that can give me this info as well..

Im relatively new to thread milling but now are shop is going full bore with it. I found specs for threading npt threads and straight threads but now we are getting into nps threads and others I cant think of off the top of my head.. I have already found some dicrepancys in our geometry that we use for 3/8-18 npt but have since figured out the correct major diameter to use to get the right end result. I am wondering if there is some kind of spread sheet that gives you all the info needed to thread mill standard and metric threads and of all different thread categories unc,npt,nps, etc ...I guess like a configuration sheet , you input the thread type you want and it gives you the right numbers and what not to go buy to achieve correct end results..thanks in advance..

Currently using that style reinshaw touch off probe TS27R in our new toyoda Vmc. It works good for getting u close if your not worried about .002 plus or minus on your touch offs. In order to get a accurate touch off you have to blend your cutter to a established surface and adjust for it in your lenght offset page for finishing tools you can't afford to be making cuts too deep. I personally thought it would be at least within .001 at most being its a reinshaw probe. But we just order a new part pick up probe and laser touch off system from reinshaw hoping for tighter tolerances on the tool touch offs..and decreased set up times with the part probe. Hth..

ok I figured it out somehow today and cut a threads using a solid carbide carmex 18 pitch cutter for cutting a 3/8-18 npt in hardened H-13. Now I want to start doing more thread milling and was wondering if anyone had any specs on speeds and feeds for carmex cutters for thread miling.I went to there web site but they want you to email them the info and they generate the code for you. it would be easier if I could just input these specs my self into MC on my cutter parameters and go from there.. thanks again..

Im not running X6 so I can't open the file. I do know I'm using a tapered cutter pretty sure its a 3 row multi flute cutter its also solid carbide its not a single flute..I'm needing to tap a id 3/8-18 npt threaded hole..never done this before. Not at work to get the name or style of cutter just recalling what I saw today about the cutter. Thanks..

Im new to thread milling and have read through the topics in the search of the forum on thread milling. I am looking for a example possibly geometry and settings in a mcx file that I can reference to in machining a 3/8-18 npt. I know we have a tapered thread mill just for this application but I do not understand how to tell mastercam the info needed for milling a 3/8-18 npt.. any help is greatly apprecitated..thanks..

Any one got any examples of good mains to run in memory mode to call out subs from data server on a fanuc 18i-MB control for a toyoda fv1680 machine. I got one from and older fanuc 18i but it you had to take the safe start out of sub program to get it to run. now with the same main it throws up error when it calls out the g5.1q1 for next tool in the subprogram unless I leave in the safe start that MC generates at the begining of each tool path it posts out.. this dosent make sense to me so im wondering ifg I need a new main program. heres an example of what im running for a main. % O0001(MAIN) G00 G40 G49 G80 G91 G28 Z0.

I made some fixtures in the past out of a dense wood material that I always called wrenwood. I need to get this stuff again but have lost the info to the company I used to get it from and wrenwood is not the actual name of it for google dosent give me link to what Im looking for. It use to come in 6foot by 2 foot lenghts and 2 inch to 6 inch thinkness. Im wondering if anyone on here has used this stuff and knows the proper name for it or something that may work better for making a clamping fixture to hold plastic parts that need to have areas machines on them. thanks,,

yeah I knew they were basically a crossover cable but the ones I have seen in the past like allan listed above supports hardware handshake capabilites as well as loopback testing from the machine and the pc. I finally got ahold of milltronics and they sent me documentation on the wiring they reccomend which is the simple software handshake setup and the pin numbers that get crossed.. I couldnt find what pin numbers exactly needed crossed I made one yrs ago like allan has displayed but have forgotten since then what was what..thanks for all the info..gonna save that cimco link in case I ever need it again..

Anyone have or know where a wiring diagram for making a db9 to db25 null modem cable is that works for a milltronics partner machine I believe its the centurion IV controller..thanks,,

thanks man.. not use to the new site yet..lol..

Been a while since I been on here and the forum has since been upgraded but what happened to the FTP site that was accesable to forum users is it no longer available or someplace else now. I did a search and come up with nothing.. used to find alot of helpful free ware utilities on there and would check it out from time to time.. thanks..
