Closed Wall Keller

[TheePres]

Anyone willing to take a look at Closedwall.MC8 in FTP site. I need to keller closed angle wall with a dovetail like tool, and none of the surface toolpaths will allow the undercut.

Use Flowline and turn off the gouge checking and use the "Direction" switch to get it out of the way on retracts and stuff. I do this all of the time.

Turning off Gouge Checking did the Job. Thank You.

[Guest CNC Apps Guy 1]

You're welcome.

Well I had done it I guess you don't need it on the FTP.

 

I put it up any way.

I know we discussed this previously, but I am wondering if in defining 1.00 Diam Dovetail with corner radius will MC think smaller diam.? Does this make sense? I need to end up with 1.00 after radius.

It is going to look at the widest part if that is 1" at the Arc tangences then yes.

I would think that if you define the tool correctly it will make the proper calculations.

One thing to watch out for is your transition motion. Broken is the default, it transitions in the xy first then z which is great for a regular toolpath without undercuts but gouges on a toolpath with undercuts. Either direct or smooth work well.

 

hope this helps

[TheePres]

Is it possible to draw a 2-d flat tool and define it as tool?.

 

Roger, i did notice that transition you mention and on this particular geom. none of other methods would work, So I saved toolpath geometry and stiched it manually the opposite way.

[cadcam]

Did you look at my file by chance it worked perfect.

 

I just checked it and updated it to the FTP

I did look at your toolpath, looks great. Geometry i loaded is just a small cut of actual part, not allowed to place entire part in FTP. The smooth transition you have used is not appropriate to this part, and broken transitions as Roger pointed out go into wall first then (Z) axis. Thanks for your help and input.

[cadcam]

Well its to bad you can not share the hole file.

this way I good go over your real issues.

 

I thought this was the hole part sorry.

I do alott of this type of work.

 

Later jay

Jay,

You guys did great in showing me how to run the toolpath. The only issue would be, greater control of broken transition direction.

[Roger Peterson]

Can you post a file that contains all of the undercut areas only?

 

if not good luck,

[TheePres]

Have added Closedwall2.mc8, that shows corner of part with undercuts.

[Roger Peterson]

TheePres, change your gap motion from smooth to direct in the gap settings dialogue box this will eliminate the gouging of the side wall. On the surface parameter page in the direction dialogue box punch in 10 in the retract angle and this will eliminate the gouge on the bottom of the part. Having problems uploading the file to the ftp.

 

hope this helps,
