In the Operations Manager, green check the toolpath you want to edit, "right click" with the mouse to get the drop down menu, "Toolpath Editor" is on that list.

I am on X7, so am not sure if this will apply to higher versions - You can also use the toolpath editor in mcam to change individual moves on toolpaths, so it will post with the reduced feed rate, but AFAIK you need to manually set each arc individually. It's a little time consuming. On this forum there is a post about setting a post processor up to do that for you automatically. Search for "Linear to ID/OD feed rate convertion" if you are interested in that. Either doing it yourself or maybe having reseller implement it for you. I haven't run any programs with it yet, but I am going to and think it will work well and is a good solution to this. I have always edited the code by hand afterwards when I knew there were arcs that would need it, or if there were problems running a program, and that way is also time consuming. I thought I had seen a video a few years ago showing doing arc feedrate changes with the "Highfeed" option, but I have never played with it, so I am not sure if that is possible.

Thanks for posting this Colin. I had thought this was interesting when I first saw it, and put it in my mpmaster post I use for the horizontal machines today. I like it. For some reason though, on the first depth cut of a toolpath I am not getting the adjusted feedrates on the arcs. I am using post version V16.00 P0 E1 W16.00 T1369940991 M16.00 I0 O1 of mpmaster. Might anyone have an idea of why that would be, or what to look at? Edit : I just noticed that if the toolpath that is using the arc feedrate adjustment is not the first toolpath being posted, it works just fine. The problem I have is showing up if the toolpath with the arc feedrate adjustment is the first toolpath being posted, and only on the first depth cut. ( 1/2 FLAT ENDMILL TOOL - 1 DIA.

That's weird. I occasionally have issues like that with a file. Where the stl is being saved in a different location/orientation, or is being brought in by verify in a different orientation/location. The only work around I know of is to either Xform stl and move the stl by the amount it is off in verify, or open the stl file and move it where it needs to be and then use it.

When I save the files, I make sure I'm in Top/Top view. Then I do Save Some, select the solids you want to save, then save it as a .stl file. Try doing that and see if your model is coming into verify in the correct spot.

Yeah, soild model for just the part and select the solid for verify. And then an .stl file for the part and the fixture. My opinion from over the years if if I can't get a solid model of a weldment or casting to make my own. It makes it easier to make an accurate program and catch mistakes and I think is worth the time to make models if needed.

I think it's the "Swept2R" Chook that will take a wireframe path and change it from zig zag to cutting in one direction.

Could you use contour toolpath on one edge of your shape, use the stock to leave to get the tool where you want it, then save the toolpath geometry out of the backplot?

I am assuming you want one work offset? In your Transform Operation Parameters, under Work Offset Numbering, check "Maintain Source Operations". Then under View Manager set a work offset for your initial plane to the appropriate number. And I believe the Method should be Tool Plane in the Transform Operation Parameters. (I am still using X7, so I can't be of much help if the software has changed much after this version. I don't know if it has or not)

Hello, Right now if me an the other guy at work that programs have the same file open, we can both be saving right over top of each other's work and not realize it at the time. Is there a way to where if you open a file that the other person already has open, you maybe get a pop up message saying that? Maybe more of a Windows question than a MasterCam question, but was wondering how other people handle that situation? Oh, we are using X7 and Windows 7 Professional

OK, thanks. I'll have to try that sometime.

Hello, I am using X6. I have a program that I made for an HMC, and I want to take it and change it to a live tooled lathe. When I go to "files" in the toolpath manager, and go to "replace" it will only let me grab other ".MMD-7" files, I can't see how to get it to see ".LMD-7" files. Under the file type filter there is only ".MMD-7" file type listed. Is there a way to switch between lathe and mill machine machine definition and keep the toollpath the same as they already are? Or do I need to do something like export the operation and import them into the different machine group? Thanks, Brian ***edit - OK, I just copied and pasted the operations into a different machine def, and it seemed to work ok. But now I am curious on if there is are other ways to accomplish this?

I didn't do it on the mill posts, but on the post I use for the Mori NL's, I put a pop up alarm in if the work offset for if a plane isn't actually set to a number in the view manager. The way I set the post up everything needs to be G54 for the main spindle and G55 for the sub, so I have the post toss an alarm if a plane isn't set to one of those two numbers. A bit more to put in to cover the work offset numbers you would use on a mill, but you might be able to set up the same type of thing.

I've modified some things in the post, but this is the post we were using for the Okuma's when I started working here. Here is the header from the post: [post_VERSION] #DO NOT MOVE OR ALTER THIS LINE# V16.00 P0 E1 W16.00 T1349277595 M16.00 I0 O0 # Post Name : Generic Okuma 4X Mill.pst

Ron - No I never tried going the other direction and seeing if that got the same results. I'll check it out tomorrow. Goldorak - Wear comp. Yeah, your code looks how I would expect.

I found a parameter page in the Okuma manual, and I took a picture of the parameters on the machine. The link is a droppbox link to the pdf and the picture. https://www.dropbox.com/sh/altgji635smvh5u/AABOenkBxIQzvo4IUrDs-l4ca?dl=0 Any Okuma Gurus know if there is anything there causing any issue with the cutter comp?

oops, posted in the wrong thread, moving to the right spot

Brad - We program the centerline of the tools. So start value is 0. On the program I was having the issue with yesterday, changing the offset at all, positive or negative, caused an alarm. Orvie - Thanks. I looked through our machines parameters and couldn't find a page that looked like that. I'll have to look in the manual and see if it is maybe a numbered parameter? Seems like a likely possibility that something like this could be the issue.

So, I've ran into from time to time on programs for out 2 Okuma mills where the operator can't change the tool diameter offset without getting an alarm. The control is OSP10M/OSO-U100M. Everytime it happened I thought "I need to figure that out", but never did. I think I found out today. It looks like the Okuma control actually turns comp on on the line after the line that has the G41. So, for milling circles, if there is a G2/G3 command after the G41 line it alarms out. Having another G1 line in between fixed it on a program we were running today. I changed this: G0 G90 X0. Y0. S2700 M3 G56 H4 Z6. M8 Z.1 G1 Z-.53 F60. X.0921 F21.6 G41 D4 X0. Y-.534 G3 X.634 Y0. Z-.5144 I.0921 J.534 X-.634 Z-.4831 I-.634 J0. X.634 Z-.4519 I.634 J0. X0. Y.534 Z-.4363 I-.5419 J0. G1 G40 X.0921 Y0. X0. G0 Z.1 Z6. to this: G0 G90 X0. Y0. S2700 M3 G56 H4 Z6. M8 Z.1 G1 Z-.53 F60. G41 D4 X.0921 F21.6 X0. Y-.534 G3 X.634 Y0. Z-.5144 I.0921 J.534 X-.634 Z-.4831 I-.634 J0. X.634 Z-.4519 I.634 J0. X0. Y.534 Z-.4363 I-.5419 J0. G1 G40 X.0921 Y0. X0. G0 Z.1 Z6. And then the cutter comp worked at the machine like it was supposed to. It seems like this is the fix. Wanted to see if: 1. That is actually the explanation and fix for this problem. and 2. What to do to my post/mastercam settings to get the output that will work for the Okuma mills?

Yes, just the top of the boss.

The orange is the finished part. Made out of 3/4" x 3" stock. There is .060" on the face. If you want to play with it sometime, I would be interested to see how you approach it. Or anybody else that wants to also, feel free to have at it

JoshC - I hadn't thought about that. That would eliminate a few steps. Thanks! Also, if you have time, what would you do to accomplish the same thing? I'm by no means locked into doing it like this, or think it's the best way, just kinda how I developed to turn a program into a production program. It is pretty much all Aluminum parts, and not a ton of metal coming off. Generally just want to blast through it Getting rid of those up and overs cuts a decent chunk of cycle time out. BCW - I had not noticed that option before. I will have to check it out, Thanks!

So on this particular part today, I am cutting back and forth roughing with one toolpath. Then up and position and a rough and a finish on a boss with a seperate toolpath, stepping over .010 on the depth and dia for the finish pass. So for the boss I want to use cutter comp. I can just offset the geometry and use wear comp like normal, easy enough. Was just having one of those moments where I go "I wonder if there is a way to get this to work with the cutter comp actually set to off" I assuming not, but curious.

Hi, On X7, is there a way to get cutter comp output if I use geometry for the centerline of the tool? What I do is use the contour toolpath to get stepovers and depths like I want, then I save the geometry from backplot, and redo my toolpaths cutting back and forth with no retracts to get rid of all the up and over moves, and keep the tool down.

if it just a straight bore, you can use a regular lathe drill cycle. Just put in the radius you want to drill at as the "X" position for the drill point on the lathe drill parameter page. I was always told 2/3 of the insert edge is the max DOC for an insert. On an indexable drill, that is a pretty big stepover, so do what makes sense to you. I took a .200 DOC with a 1-3/4" dia drill in aluminum the other day and it worked great. Remember, if you do boring with a drill, the setup guy is going to set the offset as a drill, so you need to account for that in any boring part of the program.
