lathe backplot groove

[babolino]

hello all,

 

Is that still a bug or am I missing something?

 

when I select a second offset in the groove-finish box, it backplots the wrong cotter edge.

 

I think it only happens whean I chosse cutter comp in control.

 

the code seems to be ok.

 

in verify it´s also the same, it cuts to much of the part.

 

any Ideas, anybody has the same problem?

[babolino]

anybody?

[Columbo™]

In the tool, parameter page, did you adjust the compensation there?

I have had the same prob here as well. One guy's looked good in backplot... then trashed his part.

@ Columbo:

 

What do you exactly mean to adjust the compensation?

[Columbo™]

Look in the tool description under the parameter page, the compensation is on the lower left.

 

[babolino]

sorry guys, I think I´m to stupid today.

 

can somebody describe "how to" step by step?

 

thanks in advance.

[Columbo™]

Double click the tool, go to parameter page, bottom left are the comps.

[babolino]

Okay, so far, so good.

 

I tried all the settings it doesn´t changes anything but the position of the corners in the toolpath.

 

when I choose the comp type "center", it cuts in to bothe walls of the groove.

 

I tried with a lot of groove forms. when I chosse the groove to be defined by a contour, select a secon offset and chosse "control" in comp type it happens every time.

 

can anybody try that and If your toolpath is okay would you please post it on the ftp?

[Columbo™]

Can you send file???? (e-mail)

[babolino]

hello,

 

I´ve put it on the ftp in the lathe directory,

 

file is "GROOVE_PROBLEM_2ND_OS.MCX"

 

thanks again.

babolino,

 

In your groove finish parameters page, change the compensation type to " computer "

 

When in control it is compensating the tool width ot your tool.

 

 

PS..... heck of a groove

[babolino]

......and that´s the point. In some kind of situations we need the compensation to be computed in the control, I just want to know if there´s a way to show the correct toolpath moves in backplot and verify when cutter compensation is selected to "control".

 

anyway is that a bug, or it´s just unusual to select comp type "control" when working with a second offset?

[Columbo™]

I see what you are saying. I'll look into it in more depth in the morning.

 

Sleepy eyes will not help the situation right now. Been here since 5 AM.

Mornin'

 

I looked into a bit this morning and I see your concern. I usually only use the "computer"

as the compensation type. I did try all options and agree that it does violate the part. I'm not sure if its a bug or not.

 

Hopefully someone can help resolve this.

 

Good luck
