Are you doing both undercuts in the same toolpath? Or, separate toolpath operations for each one? Which toolpath are you using?

from a previous posting. quote: What would be truly appreciated is an honest statement from CNC Software about MTM and where it stands. Considering the many broken promises regarding MTM, it seems only fair that that some kind statement or press release should be made. The lack of 'official' statements regarding MTM are only alienating loyal and patient customers. This thread did go a bit off topic. But, we are still patiently waiting for that "official statement" from CNC software on where they stand on this.

ahhhhh... I just reread his post. I believe you are correct.

Check out Mitsubishi Carbide. I opened the catalog and found a few different choices.

quote: Your D+Z+ isn't sticking because you have the "update tplane/cplane when changing graphics view" checkbox checked in your settings configuration. Uncheck it and your t/c plane will not change unless you change it manually. Or you could add a hotkey or a RMB button for "planes = +D+Z" to make it easy. Can't you set that right in your machine def also, under General Machining parameters, so it is defaulted to the machine you select? quote: hey Kaz, where at in MI are ya? Tip of the thumb.

I'm working on a job with c-axis contours on the main right now. Its a good thing we don't have any machines with subs.

quote: I have been hearing that since...I dunno...like the first X version...."just wait till X2"...then "just wait till X3"...ect. Why wait when there are other viable solutions? Waiting for a maybe is a waste of time and money. When I first started at my current job we were running v9. I convinced them to keep up with maint. and stay up to date. We made it up to the X2mr2 release. I finally got the other guy to start using X2 about a month ago. But as for the future releases, I don't think they are going to keep maint. on my seat. Lathe hasn't had any improvements that are worth the cost of paying it. And yes, i was told the same thing since X. Still waiting.

quote: Do you have IGF-XL or Advanced one touch? It's IGF-XL. What is the difference with advanced?

Actually, I have the full Okuma ADMAC Parts package with One touch IGF, OSP simulation and complete 3d machine models. It can do some awesome stuff. I haven't really used the one touch IGF much. The problem i have with admac is that it takes me way to long to program parts with it start to finish. It seems that the amount of time allocated to programming a part these days keeps getting shorter and shorter. I can just do it way faster with mcam and manual edits if 4ax. Then a quick program check. On the other hand, it does give you 100% guaranteed and fully verified code with all the "bells and whistles" specifically for your machine.

I figured you would show up at some point in time. I remember talking to you years ago on this topic. Nice clean code you got there. Maybe one of these years i'll finish that 4ax post i was working on.

Yep...pinch turning on that one. quote: I haven't seen Okuma code in many moons. That is pinch turning. We always started the top tool .01 closer in Z and the bottom tool .100 closer in X so they would cut first and second pass at same time, then the depth of cut could be doubled for each turret. I personally prefer doing it that way, double depth of cut, depending on the part of course. But, there is always more than one way to skin a cat. I'd post another example, but my work day ended an hour and a half ago. Anyone else have some example code? Or are we just gonna criticize what i posted? Edit: BTW 32 Okuma CNC's, 15 of em lathes. and that's just in this building.

quote: Why so many synch codes? Honestly, I didn't notice that before. That's a good question. One that i can't answer. This was programmed in '99 buy a guy that isn't here anymore. I just grabbed the first one i saw.

Here is sync'd canned rough cycle. This actually runs on an LR25 4 axis. But the code will run on the LU also. Note this is manually edited code, not straight from mastercam.

We've got an LU-400M here. Awesome machines. I'll see if i can dig up some code for ya.

@ dfehrman excellent first post quote: As my Milling Programmer has no problem creating flawless programs with no editing required, for MTM, I fight this all day long Yep, i fight this all day long also. Makes for a fun work day, doesn't it? quote: For milling, I give you all the credit in the world - excellent job!!! For us MTM guy's - you are FAILING MISERABLY. nuff said.

Try creating a point where you want to start. Then chain that point also.

quote: I would make sure the imported geometry was on an unused level before I imported it. my thoughts exactly.

It's pretty straight foreward really. Just make sure you use color 115 for the tool body and color 55 for the insert. Both body and insert must be closed chains, and the insert must overlap the body. -edit- and as gcode said, its alot easier if you have something close to start with.

quote: Hey Dave, Google this: iscar chip thinning calc And the first link will be an Iscar Excel spread sheet with all kinds of useful stuff in it. The 7th page of the document has exactly what you need. The iscar excel file is what i use to calculate surface finish. Works like a charm.

Check out which colors you used when you drew the tool. Taken from mastercam help: "It is strongly recommended that you use the default insert and holder colors. The default colors are: 14 (insert up color), 55 (insert down color), and 116 (holder color)."

If you mean to get the tool to rapid out of the hole, set the ref. point in toolpath parameters to a positive Z. edit: I should read all posts before replying

quote: What's it going to take to get Lathe fixed fed up with the basic things never getting fixed. I dont even have to list them. anyone using it already knows the stupid problems. Money would be well spent on a new lathe package from someone else amen brother and yes, we are all aware of the stupid problems with lathe. I, for one, am getting sick of doing this ->

If all else fails. Try drawing a vertical line from the end of your toolpath down to the drilled hole size, and add that to your chain.

I have never attempted to broach keyways on a lathe. But, I know PH Horn makes tooling specifically for this application. You should check them out.

so you are trying to change a post for a specific machine def.???
