Port milling X8 educational

[Azi]

Hello everyone,

it has been some time since last i asked you about help.

Now i have different problem to solve - Port milling

 

part to mill:

 

I have pre-drilled a hole:

 

Now to my problem:

- how do i tell to mastercam not to go behind a green line A

- it starts machining like i want, but then skips in the depth causing many many collisions

(don't mind my imaginary long tool)

 

Results:

Our school has edu version of X8, so if smn is willing to take a look directly at the toolpaths and my flawed settings, i would appretiate it.

Even some pdf sample with "how to" settings would be nice.

Tryed it with lollipop mill:

roughing with flat mill:

 

Toolpath with lolli:

 

0 result - the tool wont cut into material:

Z steps from previous operations are 0.5 mm

 

Settings:

 

I think i have tryed literally everything to make it work, sadly with 0 results.

I even tryed to use bigger tool for simulation, nothing happend.

Its hard to tell what you are doing with out actually seeing the file. Do u have 5 axis for this part? For the green line, try splitting the surface at that line and then select the top part of the surface as a check surface. also if that is a flow line tool path I find creating the spline to the out side of the port will usually drive the tool better. Its hard to guess at it Ive been on port expert since X6 so its been awhile since Ive used flowline
