How did you adjust the angle. Do you have a special adjustable threading bar? I've never seen one, was it homemade or bought. Not to say they don't make them like I said I've never seen one.

You could also use approach, retract points in your already created operations. In home/ref points under linking parameters. That way you don't have to create an extra op & will give the same result.

Subs +1000 I wonder if many in here use them as not much is said about them in these type of transforming posts. I know I can't live without them. I don't like having a program consisting of redundant code if it's not needed.

Lil more info would be nice. Make sure your depth is set to the bottom of the slot in parameters not the top & use depth cuts if needed. Chain can be at any depth but your depth parameters must be set right. Don't worry, all new users do something like that I know I did on my first post. I think they should make new users read the guidelines before you can post like you have to do when downloading somethings when signing the agreement. I know most don't read those things but it could help cause there aren't that many guidelines. Even make you look at it two times so you really read it. Welcome to the forum, there are a lot of good programmers in here that are willing to help. I have learned many things that I've never thought to ask along with my questions. Don't be afraid to search for things, there's alot of info there also.

Do it in the lathe if you don't have a tap to finish the thread. I ran into this a few years ago & after a scrap part did the next one in the lathe. Now we have a tap. I don't think a smaller insert will work either because of the angle of the helix. Only with acme. You almost have to see it yourself to understand why it won't work & even when you see it you still scratch your head a bit. I've been through it. Good luck.

Did this work for you before you mixed the posts up? Is your post set up to output g55 for every path? I understand what you want to do with both offsets being output. Check control deff so that work offsets is set for work system. Could be a post issue also. You might have to force your coordinates to be output. Check the control deff first & if that's ok maybe a post guru in here might help you out. Search for pwcs in here & lots of topics come up that might help you.

I only have 35000 bytes in our mill, it sucks big time but I've gotten fairly good at shrinking programs through filtering & subs but I do have to dnc a bit also. Its a good old leblond makino & makes good parts but almost no memory. I was told to double our memory it was gonna cost 10 grand or something crazy like that. I wish we could get 20 megs for 3g. Sounds like a bargain in this industry but a ripoff in the rest of the world.

I'm not sure if this adds anything but I'll say it anyway. Say you want to create 40 of the same parts out of 1 piece of stock using 1 work offset. You can use transforming to machine all parts after the first part with a similar method. Do your 1 first path then transform it. You can even kinda of nest your parts this way if you don't have that option using transform mirror, rotate etc. You can subprogram using inc so your code isn't a mile long. This can be very handy. Thought I'd add a little more about transforming for those who don't know much about it.

If you are in the machine deff it will only let you pick posts that you set up in the control deff. Go into control deff click click post tab then click add files. Click post you want to add. If there's no post there for your machine you can update your posts with updatepost.dll in chooks.

Damn that would suck. What all did you break when that happened? I know I would've had a hard time not breaking something or get away from it for a few minutes to cool off. 

I would think almost everyone would agree with Dave. Even if you are using new cutters if the machine isn't perfect (has any slack at all) you have to adjust your wear offset. I wouldn't program any finishing without it. Kinda sucks there's no wear offset on surfacing or hst paths. Had to do some work arounds today instead of using a simple flowline or contour path. If you'd research using offsets a little bit it's very easy. If part comes out small enter 1/2 that amount into your wear offset. That's literally all the operator has to do. Just as easy as setting your tool length offset at the machine so your operator shouldn't have much trouble with it. IMO

I will admit when I'm wrong & I think I might've been wrong on this one after thinking about it a little more. I've done multi starts on cnc before but I oriented the spindle whatever degree needed for # of leads then using the same threading code. On a manual (been a while) but I thought the threading dial will engage at the same position nomatter where you engage it. So as nine blue says you have to index it. In the old days I've even seen a centerline scribed then adjust the top compound when halfnut is engaged until you are positioned at 180 on your centerline. Kinda crude but have seen it work. I would like to hear how it worked out for him also.

Didn't predator show you pocketing the wall? Haha I think we've all been there. It's always some dumb little detail that'll burn ya.

Crazy millman is right u need to move back .5 cause of the 2 leeds. 1" will cut at the same pos as your 1st pass.

Na, no darts coming from here. Were right & the rest of the worlds wrong, yeah right!! I was told in school 25 years ago that we would be using metric & sae would be dead by now. Probably won't ever happen. Salah is definatly right about speed & vibration, but 3000 still seems slow.

Wow I didn't think Aussies spoke anything but metric. Learn something new every day. 

If you have auto selected mastercam doesn't need geom but it puts the tabs where the software thinks they should be. If you want the tabs in specific places create square points at desired positions, select manual then check the use square points box. HTH

Setup your operation defaults. Do a search in help for operation defaults it will show you how to do this. This schould give you what you need.

Hss or carb? What's the material of the part? Need a lil more info.

I use the same post that you are using and it outputs G94 (ipm) for tapping. I've never seen a G95 output from it. There might be a switch in the post for it, not 100% sure but is something you could check.

I don't see it in the ftp where you said it is.

The part you are machining was it a model or print that was imported or did you draw it yourself? I know sometimes when I import an inventor or autocad drawing the arcs are segments not arcs. I think this might make mastercam output line moves instead of arcs. I know filtering can solve this problem if the lines are close to an actual arc but if they are not smooth enough to be considered an arc this may be causing your problem. Maybe create actual arcs yourself, toolpath them and see what your posted code looks like. Just a thought.

Honestly I myself don't get to use them much due to the jobs we do & our machine has less memory than a calculator so i have to dnc or filter the crap out of them to use them. While saying that don't get me wrong these toolpaths can be very efficient cutting the material. Dynamic mill Is a very nice tool & the other paths can be very useful also, 2d & 3d. Looks like X5 is gonna have some new 3d paths that look very cool. Depends on your machine & the part you are working on. It's something worth looking into IMO. 2d hst chaining is a little different than what you are probably used to. Look in help & play with the paths a little bit.

Tapping oil +++ , coolant works sometimes depending on what coolant you are using. Using both won't hurt. Definatly use an interrupted tooth tap as others have said.

I'm glad to hear someone else has the tools disappearing with multiple machine groups. Happened to me the other day & had me confused. Thought I did something wrong since I started the program a few days before & was picking up where I left off. Some of my tools were gone in my ops. Hope it gets fixed.
