Multiaxis Toolpath Problem

[Verisurf - Ernie Husted]

Is there any 5-axis programmers out here that would like to have this fixed?

 

I have tested and tested it and it just doesn’t work, I still have to make my own toolpaths to get around this problem.

 

I’m referring to the Multiaxis Toolpath Entry/Exit Approach and Retract height. I can not get it to feed in from the Feed plane or the Approach height, when I select the Entry/Exit stuff the Toolpath always Rapids to the start entry point; this is like rapiding right to the floor of Contour or Pocket, that wouldn’t be good! We need the same Feed control for 5-axis Toolpath. Both Curve5axis and Swarf5axis have this Rapid problem. We need to be able to feed in and out of the Entry or Exit point.

 

Other then the above problem, Curve5axis and Swarf5axis does create very good toolpaths.

Ernie so are you saying you have a fix for this

Or putting one togeather?

[Verisurf - Ernie Husted]

No fix,

 

Just looking for other 5-axis programmers to agree so that Mastercam will fix it.

I'll try it out today or tomorrow and answer back on my opinion but at face value, I'd have to agree with you.

 

Is the rapid move in the NCI? Could the problem be in MP?

[cadcam]

I Agree I would like to have feed plane to the entryexit.

[Tri-Tech]

This one needs attention.

 

We need tools that work

[cadcam]

Have you folks tried calling CNC?

I HAVE HAD THIS SAME PROBLEM AND PRIOR TO 8.1 IT WAS NOT THERE.5AXIS SWARF AND CURVE ARE MAJOR IMPROVEMENTS TO RULED 5AXIS BUT THERE ARE PROBLEMS WITH THE QUALITY(I MEAN SHOULD YOU HAVE TO EDIT YOUR DATA MODEL TO MAKE IT USEABLE).

[Reece L Gibson]

I have a file I will upload to the FTP site if it's O.K.

I played with Entry/Exit parameters on the Multiaxis parameter page ,used the 5 axis post that shipped with Ver 9 and it feed into the work and not rapid motion.

Is this what you want?

[Tri-Tech]

MillTurn, thanks for the your time.

 

We don't need to post it, we can see a Rapid move with Backplot.

 

Rapid from Clearance to Approach height, feed to start of lead-in, feed in length,thickness and height values simultaneously.

I agree with you Ernie.

 

Seems as though I cannot get it to feed in those conditions and I believe it should. Thgough it's never caused a problem with the types of parts that I have done, it could potentially cause a problem if I had more stock than I thought.

 

James, shhhh, you're yelling! Turn caps lock off please.

[James Barnes]

james IM YELLING BECAUSE ITS an imPORTANT issUE.

[Guest CNC Apps Guy 1]

Ok, Ok, sheesh.

[Tri-Tech]

There is only four other 5-axis programmers out here.

 

Come on there must be more then that

Well, considering there are probably only a couple hundred or so 5 Axis Milling machines in SoCal and a large percentage of them are in CATIA/UG houses........ do the math, then on top of that add the bootleg factor, those people don't always like to speak up when criticizing something they are getting for free....

 

So.... Ernie, are you saying that someone at CNC does not think this is a valid issue and that's why you're "taking it to the streets"????

That is right James,

 

I think it worked

Can we do a poll to see how many Mastercam 5-axis Programmers are out there?

[sir Camalot]

Count Off; One......

We do 5ax, though all in wood. I haven't had to use this. I see where this could allow alot more control and would like to see it refined.

[sir Camalot]

After looking at this a little closer, if you don't use either setting in entry/exit(approach height or retract height)and you set the retract to desired height and feed plane to desired height(multiaxis parameters page) and then adjust the plunge rate and the retract rate (tool parameters page)to the desired amounts would you really need the other buttons?

[Guest CNC Apps Guy 1]

Uh, I would be three.

[Ron Roderick]

I would be another. Only have access at work, but can't get out on the web.

So am I 4th or 5th?

Count me in,,, Deckel Maho 50e

[BOBANNON]

Well, I am a 5 axis user but with lasers not mills! Are there any other Laser, plasma, or Waterjet people out there? I've used several CAD/CAM systems but I am new to Mastercam and having a wonderful time trying to get decent output....our support tech says "well I thought your posts worked fine." NOT.

 

P.S. I agree that your problem should be fixed!

 

....Still fishing and very hungry.

[Ron Roderick]

Cadcam,

You can be 4th, I'll take the fifth.

We also have 2 posts with a lot of hard wired safety moves that i would like to get rid of.

I alter some of our 3-axis posts for Yasnak Matsuuras. Our 5-axis machines are Deckel-Maho 60 and 125 . I have only used 5-axis shwarf cutting on two jobs, most of our work is done in 4-axis planes on rotary tables. We found that G7 in posting for our jobs are easier to set up
