milling a 90 degree V groove in abs with a 90 degree V-tool

[katy.eldridge]

I am trying to programme a CAM path to cut a V groove 4mm deep 90 degree 8mm wide.  I have programmed the cam path using 2D Contour and changing the spec on the countersink tool in the library.  The groove has to reach a point and not flat on the bottom.  

The programme works in fusion and cuts the groove but when its is manufactured on our Router it is cutting the groove a 1mm to short do you know why this could be? Could it be in the tool set up?  When it cuts the groove with an end mill without the 45 degree edges it cuts deep enough.  Does anyone know why this is or am I using the wrong program ?

Hi,

Did you try the „Engrave“ tool?

hi yes I did but I couldn't get it to follow the contour. I could try it again. At the moment i've been trying to trick it by picking and end mill tool in the fusion but choosing the 90 angle tool on the router this doesn't work for different depth of groove though.

Your toolpath in Fusion looks correct. That said, I'd likely favor the Trace toolpath for this, along with using Start/End extensions of the selected contours.

Hi,

I would do that with the Trace Tool.

thanks I will give that a go on the router and see if it solves the solution.  thanks so much for the advise
