Surface Finish Contour

[MattMj]

I'm having a problem with Surface Finish Contour while trying to cut some drafted (15 deg) letters. The tops of the letters are cut into a curved surface but the finish depth is flat. In other words at the top of the letter N the draft is .15" tall and at the bottom it's .05". The Surface Finish Contour will only cut down to the .05" then it stops. I cannot make it cut that last .05 of my letters. I have tried entering depths and also incremental. I have run into this problem before but only since I've been using X2.

Please help if you can,

Matt

is there still the "cut depths" tab in X2..for surface-finish-contour?

[MattMj]

Yes there is, and I've entered the top (highest point) and the final depth in and it still stops at the lowest point of the top draft. I know that sounds confusing :-)

If you can put the file on the ftp site, I will

take a look at it for ya.

Just a thought ...

in the finish contour parameter page look at the cut depths button.

 

If incremntal is checked try setting adjustment to top cut to .0001

Then adjustment to other cuts try setting it .00005. Your may want to make that a default setting.

 

If you have absolute checked put the depth you are finishing at the max. depth (-.150). You may want your minimum depth set to .005 or a tad higher.

Kannon,

Yes it is still there as my reply indicates

[MattMj]

I've tried adjusting the depths all over the place and still no luck. Also the cutter I'm using is a 15 deg .03125 dia. flat cutter.

If someone could tell me how to post to the ftp site let me know.

Thanks,

Matt

Go to the 'cadcams ftp' site at the top of the page

and pick the MCX2_files

 

I can only get on with internet explorer for some

reason

 

User name: mastercam

copy and paste it in there

(give the name of the file)

 

Or you can zip it and email it to me

My email has an unlimited file size

Try picking a straight cutter.

 

If the draft of the surfaces and the draft of the

cutter are the same, sometimes it won't cut down the

walls of the draft.

 

or try picking a 14 deg cutter. Either way it

won't gouge.

 

I never use custom drafted cutters on any of my

moulds from the tool list. I uses straight flute

and the draft just gets cut by the geometry.

 

i may choose to put a drafted em the same deg or

less in the cnc.

 

The software will never know

[MattMj]

That last suggestion worked Rick. I guess it didn't like the cutter being the same as the draft.

Thanks,

Matt

Should you be projecting a pocket toolpath to a surface?

WHat material are you cutting these letters on?
