Hi Guys,

Is there any way to get Bobcad V25 to output a helical toolpath on leadin instead of line segments on 3d toolpaths. I know I saw SBC's post on scripting somewhere here but I'll be darned if I can find it. Any help or ideas to reduce to amount of code on these toolpaths would be appreciated.

Check the posting tab for your 3d tool paths. It has an option for line or arc output. I don t think it works for the lead in, but the rest of the movements where an arc fits it will be posted as one.

Hi Al,

I see an arc fit tolerance, that I am using. I guess what I am looking for though is how much tolerance does it take.

What tool path are you using? The defualt settings should work just fine...

Using Z level rough and finish.
I have attached the file I was working with.

If you are using the Mill Pro package I would drill a hole for your roughing end mills to start in. This way you won't need to helix or ramp down in order to get in the cut.

Using ADV Rough you have the option to pick a drill tip position. The reason why it's called a drill tip position is simple. The point you pick would be for the hole your drilled, and how deep in Z it went.

Using this option your 3D rough path with start in the drilled hole and eliminate the need to ramp the tool into the part.


Do you have an older controller?

17476 lines of code with arc fit off

7517 lines of code with arc fit on

I am running an older control and using mill pro. Thank you for your suggestions and I will give them a try.

Z Level Rough with ramp option using arc fit = 1231 lines of code

ADV Rough using drill tip and arc fit = 190 Lines of code

That is a huge about of code savings!!!!!!


You asked about your arc fit tolerance. The default is .0005 But because your machining tolerance you are using for this part is .001 I matched these values

It took your Z level finish from 540+ lines of code down to 380+ lines of code. So that will save you a little bit as well.


Anyway I hope that helps.
