LOL

I really like NX but had to give my boss a little lesson a few days back on just how quick i could get something done.

Literally 10mins and I had posted code for him for a job that gets killed in NX

 

They both did the exact same job, posted good code

but some thing can be done so much faster

 

Someone has to spend time in NX day to day in order too appreciate how quick MasterCam is.

Im lucky to be able to use both

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

PEACE

 

Challenge:

I would like to create shoulder bolts in MC quickly just like in NX. Can you?

Your opinion. I've never had an issue with it.

Yeah, I remember the first time I used the Dyna Face op. The setup guy came in screaming because his finish facing path took thousands of lines of code. That was filtered at .03". Not just my opinion. Also the OP position as well.

If you really want to use face toolpath... did you know that?

I think you missed the initial post. He said dynamic facing caused code that was too large for his application.

errrr - go to contour and select single chain, and pick one of the curves. Select no comp (ie centre line) and for the lead in/out extend by 51% (for minimum air cut).

I know you're then facing with a one pass contour toolpath and not a face toolpath, but ???

Do you moan that when you have to ream a hole, you use a drilling toolpath because there isn't a toolpath called ream?

How difficult do you want to make things for your self?

I can moan, but geez, you can moan more.

That's not the point. I know how to contour. The point is the Facing op is next to worthless. Even on simple geometry.

why fix something that is not broken.

You are correct. The X8 dynamic mill paths were better than the X9 optirough. At least X8 could process the depths correctly.

Realistically, you don't need to create geometry if you use the pocket ops. Just select the solid face (and maybe an entry point) and you are good to go. 

You guys are right. The facing op is simple. I just think it is too simple. Below is a picture of a VERY simple part that MC completely bombs on.

I wish you would venture into that forest and and Fall Out of this "tree"

 

Never Heard so much dang Complaining

Please elaborate on how perfect the MC facing routine is. Maybe, after 10 years of using it, I am unaware of the proper use.

I didn't quite understand the question.

 

Guitar:   2" facemill that stays in the cut while using the standard Facing without extra geometry

Yes, that is good. And, we are assuming that he is facing simple geometry in this case. If you get any more complex than a simple rectangle, MC facing always seems to fail. Then you need to start playing around with pocketing because the MC facing paths are severely limited and start demanding 50% tool overhang. One thing that really frustrates me is the inability to specify F/S and stepover over rides for the finish pass. So, your facing almost always ends up being 2 ops.

You just need to set the parameters in the facing options.

 

Maybe X5 didn't have enough options, I can't remember

That is cutting air. The idea is not to leave the part.

I've never understood this logic personally ^. The facing toolpath always works fine for me... How much time are we talking here (wasted cutting air)? I guess if you are routinely facing 4 foot lengths or so, sure you don't want to cut air for that much, but in "regular" size blocks (3,4,6,10" etc) whats the big deal? I know someone will chime in about production and how much time you save by eliminating that one extra pass, sure I get that, but glad that isn't an issue for me! 

You said you don't have enough memory, holy crap that must stink! 

Keep in mind that facemills are generally large diameters and clearing the part of the radius of a facemill can take alot of extra time for each pass. Yeah, if your are doing 5 aluminum parts it may be no big deal. If you are doing 1000 steel parts, that can be a huge cost.

Sorry, I meant that when using depth cuts, I'd have to manually enter the value 100 times for each depth of cut. Not very practical. CAP works for each depth of cut.

Actually, what you could do is program to cut 1 depth and then use transform with a negative Z delta shift on a pth that uses toolpath editor. This would be almost the same as using depth cuts. 

For drilling CAP use 1st picture "untitled"

For contour use "toolpath editor" instead of CAP pic "untitled2"

I think you may want to go back and review your history. Starting with Surfcam  

Cool and glad NX was able to give you that type of toolpath finally. :laughing:

And, while we are on that subject. This form of milling process was NOT designed by Mastercam. This was an add on created by a 3rd party vendor...Nexion who initially created this to work within Surfcam. This process has been sold to may other Cam companies, including NX. So, don't go claiming some great achievement by MC for "creating" these paths.         

This would have been done much easier and quicker in NX. 

"Glad you got it figured out and you can define the exact entry and exit using that vertical line. "

LOL. Why would you want to? Just create entry/exit points using 2d paths like everyone else on the planet.  You can even control the entry feed over ride using this method. Creating vertical lines for entry/exit is non productive. It's like creating a 3d tool path when a taper mill can be used, and faster. Really, now. Teach him the correct way to do it. Life is much easier that way.

In X8, change at point (feedrate) seems to apply only to a single element, whereas in X9 the feedrate stays on for the rest of the toolpath. Is there some setting to make it back non-modal?

Yup. Look at the yellow icon within the CAP dialog. Look at the one you have selected then choose the other one.

Cool and glad NX was able to give you that type of toolpath finally. :laughing:

Unfortunately, we don't toolpath with NX here

what was the tool holder

did it survive the break

Most of our tool holders are circa 1970. Unfortunately, it survived. Just a stub, solid em holder.

How do they hold up in Waspaloy and Inconel?

Well, since it is an endmill made for aluminum I would say not very well. Maybe you can tell us.

Anyone having a problem linking their account?

On MasterCam.com my profile is linked to my old job's mastercam. I tried a new code and it doesn't work. Also, I'm on NetHASP if that makes any difference. We have a few days left of current maintenance.

I have always had to use a dongle in order for the linking to work. I could never get it to work from the network.

We ran hundreds of parts with this 1 end mill over the past 7 months. Yesterday I said, "sounds like your end mill is getting dull". Operator said "no way". Today, it finally broke.

I love these Swiftcarb end mills

Played.

Poorly

Yeah, I knew that's what your mechanic would say to you.
