Lathe Groove issue

Hello everyone!

 

I'm having a problem while making a groove. The groove doesn't start or ends where it should. It's leaving a lot of material causing me problems on the finishing pass. Any help please? F3d file attached.

 

Thank you all!groove.jpg

Hi @europrecisao ,

It seems to me the tool is going where it should go (see image below).

When you simulate, does it look like this on your screen?

Thanks,
Paolo

Hello! I'm having this:

And at the end I'm having the same thing:

Thanks for your help!

Have you tried changing your Stepover? That's what determines how much material the roughing passes will leave behind. You had it set to 1mm, with 0.5 I get the toolpath you can see below. 

The following finishing pass will take the 0.5mm of the 0.6 left on the part, but leave 0.1 mm on as per stock to leave.

@paolo.bastianelliThat helps at the end but it's starting the same place. I notice the tool path is coming back for the rest of the material at the beggining. Is this a normal behaviour?

Message 6 of 7

If you're referring to the very last pass, yes, that's intended behavior. Due to the fact you're doing Roughing and Finishing all in the same toolpath, the tool will go back and do a single finishing pass at the end of the roughing passes.

If instead you're referring to the last of the roughing passes, the one where the tool works its way to half the groove in one direction and the other half in the opposite direction, you can avoid it by unchecking the Roughing Clearing Pass checkbox. It's up to you. Either way, the toolpath will remove all programmed material.

 

I hope this helps.
Paolo
