Can't generate a 'correct' contour

[palr717]

Pic related, it's the geometry of the finished part.

 

problem is every time I use rough/finish to make a toolpath, it just turns the OD and completely ignores the contour. If I go point-to-point, it creates huge steps that my groove won't be able to finish. if I do plunge-turn, it'll hit the contour, but it cuts torward the positive on the angles.

 

I just want it to be one, simple pass. start at beginning of contour>cut angle/radius>cut "flat">cut front angle/radius>done. I don't understand why the rough/finish toolpaths aren't making the cut, and there aren't any settings to my knowledge that'll let me plunge/turn negatively exclusively, in one foul swoop

 

please excuse my noobiness, I'm still pretty new at this and i'm having to teach myself. thanks

Really sounds like someone should be contacting their reseller

 

MLC CAD is down in your neighborhood, might try giving them a call

uh, well do you have any idea what could be causing this problem? i apologize if this sub forum isn't for questions, i was under the impression it was

I know EXACTLY what the problem is, that however doesn't change the fact it is OBVIOUS you need some very basic training and your reseller is the source for that, a forum can't train you

 

The forum if really good for help after you have some basic understanding

 

and if you are an Industrial user this is the wrong forum, this is for educational users

yyeah, I don't have the means to take a course, and there aren't many videos online that cover the lathe in mastercam..so if you could just help me out i'd really, really appreciate it

[palr717]

or even better, if you could point me in the right direction to get some very basic training that i OBVIOUSLY need, i'd really, REALLY, appreciate it

if you looked a few threads down you would have found your answer

"how to machine an area" isn't the most telling title, but okay.

So what are good questions for the "Educational Forum"?

I went to school for Master Cam, they didn't even hint on lathe.

It was mostly about creating surfaces and milling.

I learned lathe by trial and error and help from the forum.

 

palr717,

Your problem is in your rough parameters, check your plunge parameters.
