Hey Guys; I am breaking stuff again. I am tapping three 5/16"-18 holes in 7075 AL .625 deep, I used a letter "f" drill .775 deep. I ran the tap at 270rpm and 15.ipm and the tap broke on the second hole first part so I have around 600 more holes to tap. Oh yeah the tap is a morse high proformance spiral flute bottoming tap. Castrol clearedge 6519 coolant around 6% Valenite quick change rigid tap holder Okuma mc-v4020 with rigid tap Help Please!!!

I have been working on a project for about six months off and on. The drawing is finally finished and I am starting to put toolpath on it but I am not positive on the best way to cut the part. It will require turning and mill (3 and 5 axis) work to be done. The biggest problem that I am having is that i did it in solids, and do not have a clue how to cut them. So I guess that i am asking for insite on how to do so? Next biggest problem is the part proprietary and I can not just put it on the ftp. Can anyone one help??

Thanks Salahuddin

Can you help me with the convertion from mm/min to inch/min. I am not computing all that well today.

I am reaming .125" 6061 w/a 29/64" reamer only left .010" material for the reamer to take out. I am getting chatter and not sure what speed and feed to to cut at. Right now I am running it at 1000RPM and 7.IPM. Thank you for the help in advance cause I am needing it today.

I got it to work after reading the MD-CD documents. thanks for the help. But I need to make some other changes to the post if i keep the same name will it just update on its own.

Steve, I got the original post from MC9 and updated it. I edited by going file,edit/open external, mcamX, lathe, posts. Is there another way.

Thanks John I will start reading

First thing,I have edited a post in X but can not associate it with a control definition. Second, I went back to MC9 edited the post the same way. Updated it to X and now it tells me that a program is missing to continue change in control definitions. The file that it shows in header of the dialog box is lathe.set I am trying to find the fastest way to edit a post and the test the post to make sure that it is correct for my machines. There has to be an easy way to do so that I am overlooking. Oh yeah I am real green at editing posts and control defs. Thank You for your help in advance.

Thanks guys, I raised my sfm to 400 and feed at .008. Finished from both sides like Tim suggested and reduced the chatter so that with the right light you can see it but you can not feel it in the part anymore. Thanks again for the quick response I am making parts again. Matt

The material is 1018 crs, If you know much about cars this is the fly wheel side of a torque converter. I bolt the three lugs (that bolt to the fly wheel) to a fixture plate on the chuck. the groove I.D. is 10.030. The lathe is a Okuma captain l370, Chuck is Kitagawa 10" hydralic chuck, tool hoolder is 1" shank, insert has .03 radius. I have also tried a smaller iscar tool without any luck also. I do not have enough turret space to run two tools. It only seems to chatter on the finish. It takes two rough plunges leaving .01 at the inside and outside of the groove. Than profiles the groove from inside to outside for the finish What would be a good feed and sfm for this be.

Can anyone give me a better idea on cutting a face groove? I can not cut this groove with out chatter on any of my parts. It is .275 wide and .05 deep. I use a valenite tool with a .236 wide insert 150 sfm at .004 per rev. I have tried leaving more material for finish, less material for finish, slowing the feed down and slowing the sfm down all wothout any luck. Any input I would be greatful for. Thank you in advance.

Chris, I have made some of the changes, But I have had keep my machines running also so have not got them all done. Thanks for the help. And your right on the gear change being a M I do not know what I was thinking. Sunday I like to take the day off. Thanks, Matt

Chris, I have been away a couple days sorry. Right now I use the MC9 Okuma post and modify the program alot. The machine is twin turret but the bottom turret has over .030 runout so i do not use it. In the program I have to recognize both turrets with G14 for the bottom and G13 for the top turret. It can not have any text. The machine needs 4 places past the decimal but can not have a decimal to recognize the deminsions. The machine has 4 gears that go from G41 to G44. I use mostly the higher gears. Any help you could give me would help. PM me if you would like. Thank you very much, Matt

I know asking for a post is a bad deal on the forum but could any of you tell me who wrote your okuma 3000 post. I have had my reseller and a local guy look at what i need and they have never got back to me on it. Any help on editing a post would be great also. thanks matt

Thanks John!! I redownloaded the html and set it up like the sheet said. It made a setup sheet but I have not set a machine definition I just use an updated post so I think it use mill.set and the cycle times are off. Thanks again for the help I think that I will use the tutorial on machine def. tonite to set my okuma and try again to see what i get.

I tried to do what the link was telling me to do but everytime I told it to make a setup sheet it said that installation was done improperly.

John, I have downloaded the trial but i do not know how to get the info into the setup sheet

I do not understand how the setup sheets work. I have never used them because I program, setup and run all our machines and we make a custom product so they part are mostly the same. Now I can not keep up with demand and i am starting to get help. But the help can not read my mind and does not know how we make the parts so I would like to start using setup sheets so that they will understand without me having to tell them everything. I am wanting something that has a picture of the part showing the orgin and a tool list with full description of the tool. Can anyone show the light?

Matt, My e~mail is down for server updates i will try in the morning Thanks Matt

I need help can not figure this one out. I have imported a drawing from mcam9 and made some changes to the geometry, rechained the new tool path and now i get a regen error on all of my operations. I also do not know how to put the file on the ftp. If you can help i can email it to you. Thanks a bunch, Matt

I have just purchased In-House Solutions tutorials for mill, lathe, solids, mill solids update, and 4 and 5 axis they are really good so far but I can not find the downloadable files for the drawing. Can anyone help out I maybe overlooking the obvious. Thanks Matt

This is off the topic but I am wanting to change coolant types. Right now I use val-cool vnt 800 and I am not all that happy with it proformance. I also need something that does well with hard water. Any suggestions??

Thank you guys. I will give these a try.

Can anyone help? Every time I post on a job using my fourth axis the work offset changes on every rotation. I need them all to be the same. I use the mpokuma.mmd and the mill3-axis vmc.mmd in MCX.
